The Origins of Isokern: Icelandic Volcanic Pumice

Pumice is a naturally occurring volcanic rock formed when gas-rich lava cools and solidifies. Its porous structure makes it lightweight compared with many conventional masonry materials and gives it useful insulating properties.

Isokern fireplace components use volcanic pumice from Iceland as part of a proprietary manufacturing process. Earthcore developed the brand around modular masonry fireplace and chimney systems, bringing this material into residential and commercial construction.

The result is a fireplace system that combines a natural volcanic material with engineered components designed for assembly on site.

What Makes Isokern Fireplaces Different?

Lightweight Modular Construction

Traditional masonry fireplaces are often built from numerous masonry units and substantial supporting construction. Isokern systems instead use prefabricated, interlocking components assembled according to the manufacturer’s instructions.

The pumice-based construction can reduce the weight of the fireplace system compared with some conventional masonry alternatives. However, foundation and structural support requirements depend on the complete installation and must be evaluated for each project.

Natural Insulating Properties

Pumice contains numerous small pores that contribute to its insulating characteristics. In a properly designed fireplace system, these properties help manage heat transfer through the fireplace structure.

Actual heating performance, fuel consumption, and emissions depend on the specific model, fuel, installation, and operating conditions. The manufacturer’s technical documentation should be consulted when comparing performance claims.

Architectural Design Flexibility

Isokern fireplaces are available in different configurations and sizes, with options varying by product series. Their modular construction supports a range of interior and exterior design applications.

Depending on the model, a fireplace can be incorporated into a traditional living room, a contemporary great room, an outdoor entertaining area, or a commercial space.

The finished appearance can be customized with suitable brick, stone, or other approved finishing materials, allowing the fireplace to complement the surrounding architecture.

Multiple Fireplace and Chimney Configurations

The Isokern product range includes different fireplace systems designed for particular fuels, venting arrangements, and installation requirements.

Model selection should account for the intended application, available space, chimney or venting requirements, local codes, and the manufacturer’s installation instructions. Not every model is suitable for every indoor or outdoor setting.

Isokern Fireplaces in Indoor and Outdoor Spaces

A fireplace can serve as both a functional heating feature and an architectural focal point. Indoors, it can anchor a living room, define an open-plan space, or complement a traditional or contemporary interior.

Outdoors, a suitable fireplace model can create a gathering point for patios, covered outdoor living areas, and entertainment spaces.

The appropriate system depends on the environment and intended use. Outdoor installations require particular attention to weather exposure, clearances, foundation conditions, and the product’s approved application.

A Practical Approach to Fireplace Selection

When considering an Isokern fireplace, evaluate more than appearance alone. Important factors include the opening dimensions, fuel type, installation location, structural support, chimney configuration, finishing materials, and overall project budget.

Review the technical specifications for the selected model and work with a qualified installer to confirm that the system meets applicable requirements.

Conclusion

Isokern fireplaces stand out for their use of Icelandic volcanic pumice and modular masonry construction. These features provide a distinctive combination of material characteristics, installation flexibility, and architectural design options.

For homeowners, builders, and designers, understanding the material, model requirements, and intended application is the starting point for selecting an Isokern fireplace that fits the project’s functional and aesthetic goals.

How to Measure a Stone Fireplace Surround

Explore the essentials of stone fireplace surround measurements, including firebox reference points, hearth positioning, installation specifications, and site conditions.

 

4 Factors to Consider When Measuring Your Stone Fireplace Surround

Accurate measurements are essential when planning a custom stone fireplace surround. The dimensions of the firebox, finished floor, hearth, and surrounding architecture all influence how the finished installation fits and looks.

Whether the project involves a masonry fireplace or a factory-built gas fireplace, understanding the relevant measurements before fabrication can help prevent installation problems, unnecessary costs, and delays.

Here are four common mistakes to avoid when measuring for a stone fireplace surround.

Planning a custom stone fireplace surround? Discover four measurement mistakes to avoid for a better fit, proper clearances, and smoother installation.

 

 

 

Key Takeaways:

  • Use the correct reference points: Distinguish the firebox opening from the overall appliance dimensions and identify which facing components must remain visible.
  • Account for finished floor height: Consider flooring, hearth materials, and installation layers when determining final elevations.
  • Follow manufacturer specifications: Verify opening dimensions, clearances, ventilation, and access requirements before finalizing the design.
  • Assess site constraints: Measure nearby walls, windows, cabinetry, controls, and other features that may affect the surround’s fit.
  • Coordinate before fabrication: Have the measurements and installation details reviewed by the stone fabricator and qualified installer.

Measuring from the Wrong Reference Points

One of the most common measurement errors is confusing the firebox opening with the overall dimensions of the fireplace unit.

The correct reference points depend on the firebox design, its metal facing, and the manufacturer’s installation requirements. Some installations allow the stone surround to overlap the facing, while others require portions of the metal frame, vents, or other components to remain exposed.

Masonry fireplaces also require consideration of the finished firebrick opening and any relevant installation tolerances.

Before measuring, identify the intended finished opening and determine which portions of the fireplace must remain visible or accessible. Clear reference points help ensure that the stone surround fits correctly without obstructing the firebox or its required components.

Overlooking Finished Floor and Hearth Height

Measurements taken from the sub-floor may differ from those taken from the completed floor. Flooring, underlayment, mortar, and hearth materials can affect the final elevation of the fireplace opening and surrounding stonework.

This is particularly important when installing a raised hearth or designing a hearth that sits flush with the finished floor.

Establish the finished floor height before finalizing the surround dimensions. Confirm the required depth, support, and installation details for the hearth with the fabricator and installer.

The necessary allowances depend on the fireplace system, selected materials, and construction method, so generic measurements should not replace project-specific specifications.

Ignoring Manufacturer Specifications

Fireplace manufacturers publish installation requirements that must be considered when designing and measuring a stone surround.

These requirements may address clearances, opening dimensions, ventilation, access panels, facing materials, and the placement of combustible or noncombustible materials.

A stone material being noncombustible does not automatically mean it can be installed at any distance from a fireplace. The complete assembly must comply with the appliance manufacturer’s instructions and applicable building and fire codes.

Review the firebox specifications before fabrication and coordinate the design with the fireplace supplier, stone fabricator, and qualified installer. Resolving compatibility questions early can help prevent costly changes later.

Overlooking Site and Design Constraints

The surrounding space can affect the dimensions and placement of a custom fireplace surround.

Nearby windows, cabinetry, wall returns, electrical components, gas controls, and other architectural features may limit the available width, height, or projection of the stonework.

Before finalizing measurements, assess the entire installation area and consider how the surround will relate to adjacent finishes and furnishings. Confirm that required controls, service access, and ventilation openings will remain accessible.

Accurate site measurements and coordinated drawings help ensure that the finished surround fits both the fireplace and the intended interior design.

Final Thoughts

Successful stone fireplace surround measurements begin with accurate reference points, a clear understanding of finished floor heights, compliance with manufacturer specifications, and careful assessment of site conditions.

Because fireplace systems and installation methods vary, measurements should be verified against the specific appliance documentation and project requirements before fabrication begins.

Working with an experienced stone fabricator and qualified installer helps coordinate these details, reduce avoidable errors, and achieve a finished fireplace surround that fits the space as intended.

  • Use for supplemental heating: Electric fireplaces are generally designed to provide supplemental or zone heating rather than replace a home’s primary heating system.

Quick Tips for Choosing an Electric Fireplace

Before purchasing an electric fireplace, consider these factors:

Measure the room: Compare the fireplace’s heating capacity with the size and characteristics of the space.

Choose the right fireplace type: Wall-mounted, freestanding, built-in, and insert models are designed for different layouts and installation requirements.

Compare heating capacity: Many residential electric fireplaces use up to 1,500 watts of power, producing approximately 5,100 BTU of heat.

Consider the features: Thermostats, timers, adjustable flame effects, remote controls, and safety features can affect everyday use.

Plan the installation: Check outlet locations, clearances, ventilation requirements, wall construction, and placement relative to furniture and electronics.

Consider operating costs: Electricity consumption, usage time, and local electricity rates determine the cost of operating an electric fireplace.

How Electric Fireplaces Work

Electric fireplaces use electricity to power a heating element and create an illuminated flame effect. Unlike wood-burning fireplaces and most gas fireplaces, electric models do not require combustion or a chimney.

Many electric fireplaces operate as supplemental heating appliances and allow the flame effect to be used without the heater. This makes them suitable for creating a fireplace atmosphere even when additional heat is not needed.

A common residential configuration is a 1,500-watt heater, which produces approximately 5,118 BTU per hour when operating at full power.

Electric fireplaces should be selected based on the manufacturer’s stated heating area and installation requirements rather than relying solely on a BTU calculation.

Types of Electric Fireplaces

Electric fireplaces are available in several configurations. The best type depends on the room, available space, and desired installation.

Wall-Mounted Electric Fireplaces

Wall-mounted electric fireplaces attach to the wall and generally require less floor space than freestanding models. They are commonly used in bedrooms, living rooms, offices, and contemporary interiors.

Installation requirements vary by model. Follow the manufacturer’s specifications for wall support, clearances, electrical connections, and heater placement.

If installing an electric fireplace near a television, check the manufacturer’s clearance requirements and the direction of heat discharge.

Freestanding Electric Fireplaces

Freestanding electric fireplaces sit on the floor and are typically among the simplest models to install. Many plug into a standard electrical outlet and can be moved when the room layout changes.

They are useful for spaces where permanent wall construction is not desirable, but adequate clearance around the unit is still necessary for safe operation and airflow.

Built-In and Linear Electric Fireplaces

Built-in electric fireplaces are recessed into a wall or framed enclosure, creating a more integrated appearance. Linear models are often used in feature walls and media-wall designs.

Installation may require framing, electrical work, and either a standard plug-in connection or hardwiring, depending on the model. Always follow the manufacturer’s specifications and applicable electrical codes.

Some built-in electric fireplaces are designed for indoor and covered outdoor applications. Outdoor installation requires a model specifically rated for that environment.

Electric Fireplace Inserts

Electric fireplace inserts are designed to fit into existing fireplace openings. They can update the appearance and function of an existing wood-burning or gas fireplace without requiring the combustion associated with those systems.

Before purchasing an insert, measure the opening carefully, including width, height, depth, and the available electrical connection.

Electric Fireplace Heating Capacity

Heating capacity is one of the most important factors when choosing an electric fireplace.

A typical 1,500-watt electric fireplace produces approximately 5,118 BTU per hour at maximum heat output. However, actual heating performance depends on room size, insulation, ceiling height, outdoor temperature, and other factors.

Rather than assuming that one wattage rating will heat every space equally, compare the manufacturer’s recommended heating area with the characteristics of the room.

Electric fireplaces are generally best viewed as supplemental or zone-heating appliances rather than replacements for a home’s primary heating system.

Electric Fireplace Features

Modern electric fireplaces offer a variety of features that can affect convenience, appearance, and control.

Flame Effects

Many models provide adjustable flame brightness, color, speed, or intensity. Some include glowing ember beds, logs, crystals, or glass media.

A flame-only mode allows the visual effect to operate without activating the heater, which can be useful year-round.

Thermostats and Heat Settings

Many electric fireplaces offer multiple heat settings and thermostatic controls. A thermostat can cycle the heater to help maintain a selected room temperature.

Timers and automatic shutoff functions can provide additional control over operating time.

Remote Controls

Remote controls commonly provide access to power, heat, flame brightness, temperature, and timer settings. Some models offer additional controls through a wall-mounted control panel or mobile application.

Choosing the Right Electric Fireplace

The best electric fireplace for a particular space depends on several factors rather than appearance alone.

For a simple installation, a freestanding or wall-mounted electric fireplace may be appropriate. A built-in or linear electric fireplace can provide a more integrated appearance for a feature wall or custom installation. An electric fireplace insert can be used to update an existing fireplace opening.

Heating capacity, installation requirements, flame effects, thermostat controls, safety features, and electrical requirements should all be considered before purchasing.

Natural stone can be extremely heavy, depending on the type and thickness of the material. Large fireplace surrounds are often fabricated in multiple sections to make transportation and installation more manageable.

Multi-piece construction can create visible seams or joints and requires careful fabrication and installation to achieve proper alignment.

The structural requirements of a natural stone mantel should be evaluated before installation, particularly for large or heavy surrounds.

What Is a Cast Stone Fireplace Mantel?

Cast stone is a manufactured architectural material designed to replicate the appearance of natural-cut stone. It is typically produced using cement materials combined with aggregates and other components, then formed in molds.

Because cast stone is manufactured rather than quarried as a finished architectural piece, it can be molded into specific shapes, profiles, dimensions, and decorative details.

Benefits of Cast Stone

Design flexibility: Cast stone can be molded into custom shapes, profiles, trim, and architectural details.

Consistent appearance: Manufactured production provides greater control over color, texture, and surface characteristics.

Large-format possibilities: Depending on the manufacturer and design, cast stone can be produced in substantial sections, reducing the number of visible joints.

Architectural versatility: It can be used for traditional, transitional, and contemporary fireplace designs.

Reproducible designs: Molds allow architectural details and profiles to be produced with consistent dimensions.

Natural Stone vs. Cast Stone: Key Differences

The primary difference between the two materials is how they are produced.

Natural stone is quarried and fabricated from an existing geological material, so variations in color, veining, and texture are inherent to the stone.

Cast stone is manufactured using a mold, allowing greater control over dimensions, profiles, surface characteristics, and decorative details.

Choosing Between Natural Stone and Cast Stone

Natural stone is well suited to homeowners who value the authentic characteristics and natural variation of quarried stone. It can provide a distinctive, one-of-a-kind appearance, particularly when the veining and color variation are central to the design.

Cast stone is well suited to projects where dimensional consistency, custom profiles, architectural detailing, and large-format designs are priorities. Its molded manufacturing process provides greater control over the final shape and appearance.

Understanding these differences can help homeowners, designers, and builders select the fireplace mantel material that best fits the project’s aesthetic and functional requirements.

Gas, Electric, Ethanol or Wood Burning – Choosing Your Fireplace

From gas and electric to ethanol and wood burning, discover the fireplace options available for new construction, renovations, and existing homes.

 

Knowing Your Options When Choosing Your Fireplace

Sometimes you’re constrained by the architecture of the home or business in which you live, so you don’t have as much flexibility to choose whatever fireplace you want to purchase. However, you might be surprised to find that you have more choice than you think when it comes to selecting a new fireplace for your space. There are 4 main types of fireplaces: gas electric, ethanol and wood burning. Traditionally, many existing homes in the Greater New Orleans area have one or more wood burning fireplaces with chimneys installed.

An easy transition from a wood burning fireplace to something else is to run a gas line to the fireplace and install gas logs or some other gas logs alternatives. Or, to make it even more simple, homeowners can install a gas starter and use wood like they would in a wood burning fireplace. Introducing access to gas with your wood burning fireplace opens up more options than you think.

Explore gas, electric, ethanol, and wood-burning fireplaces when choosing your fireplace and learn what will work for your home's space, style, and heating needs.

 

 

Key Takeaways:

  • Consider the whole installation: Available space, ventilation, fuel access, heating needs, maintenance, design preferences, and local requirements should all factor into your fireplace choice.
  • Gas fireplaces offer variety: Direct vent, vent-free, and B-vent models provide different approaches to heating, ventilation, and installation.
  • Electric fireplaces are highly flexible: They can be installed in many locations, offer customizable flame effects, and can often operate without heat for ambiance only.
  • Ethanol fireplaces provide real flames: They do not require traditional venting and can be used in a variety of indoor and outdoor applications when properly installed.
  • Wood-burning fireplaces deliver a traditional experience: They provide the sights, sounds, and atmosphere associated with a conventional fireplace but require appropriate venting and ongoing maintenance.

Choosing Your Gas Fireplace

Gas fireplaces come in three styles – direct vent, vent-free or ventless, and B-vent. If you have smaller spaces with less option to install a fireplace, the vent-free fireplace is low-maintenance and can be installed in virtually any space with no venting required. We have a full line of vent-free / ventless fireplaces, which you can view at our gallery page.

Direct vent fireplaces require more space and venting to be installed. This type of fireplace is installed during new construction or a major addition / renovation. Direct vent fireplaces have a 70% heat output, offer better air quality because they are venting to the outside air, a steady source of flame and warmth, and a blower that can be manually controlled for heat distribution.

B-vent fireplaces offer a more traditional fireplace approach with a vertical chimney and an approximately 50% heat output. Enjoy realistic flames and the crackle of a wood burning fireplace. B-vent fireplace installations are ideal for outdoor or for spaces that are partially outdoors like lanais and screened porches.

Choosing Your Electric Fireplace

Both the electric and ethanol fireplaces offer complete versatility as to location and use. Electric fireplace literally can be plugged in anywhere. The flames and colors of electric fireplaces are set by a remote control. You can also choose to turn off the heat and use the fireplace for just appearance and ambiance. Electric fireplaces can be moved from room-to-room, and you can take it with you if you move locations.

Choosing Your Ethanol Fireplace

Unlike the electric fireplace, ethanol fuel burns clean, and it burns “real.” The heat and appearance of the flames of an ethanol fireplace are hard to distinguish from the real thing, and yet, they have a softer, more ambient look that, combined with their design features, makes an impressive display in any room. Ethanol fireplace products can be installed both inside and out because they operate without venting or custom installation and do not produce smoke or ash.

EcoSmart ethanol fireplace units sold by Foster-Taylor Fireplaces come in all different styles, shapes, and sizes. From fire pit tables, to stand-alone square or circular units, to fire pits, bowls, and fire boxes; EcoSmart ethanol fireplaces offer multiple and varied options for your signature style or design.
