Armatherm™ FRR

Armatherm™ FRR Structural Thermal Break Material

(Thermal Insulation Material – TIM)

Armatherm™ FRR structural thermal break material provides a combination of low thermal conductivity and high compressive strength and has been used in hundreds of structural steel framing connections transferring load in moment and shear conditions.

Armatherm™ FRR thermal break material can support up 43,000 psi and has an R value of 0.9 per inch. The material is made of a reinforced, thermoset resin which is fire resistant making it the ideal material for use in structural steel and façade thermal break connections.

Applications using Armatherm™ FRR to reduce heat flow include:

Armatherm™ Thermal Washer and Bushing

With a bolt through insulation pad there is a slight thermal transfer along the connecting bolt. To further reduce heat loss, Armatherm™  bushings and washers can be used on the warm face of the structure. A thermal break at the bolt connection will reduce heat loss an additional 4% per bolt depending on the wall assembly construction. In extreme applications (e.g. Indoor Swimming Pools), to prevent condensation on the bolt head, a polyurethane nut cap can be supplied to effectively screen this cold surface from the internal environment.

Structural Steel Thermal Break Connection

Armatherm™ Thermal Break Pads are often called Thermal Bridges, balcony isolators, structural thermal breaks, cantilever steelwork thermal bridging, cold bridge isolation, thermal partitions, steelwork thermal break, thermal bridging, cold bridging pads, cold bridging solutions. All of these solutions use Thermal Insulation Material TIM to prevent thermal bridging.

More about Armatherm™'s FRR Thermal Break

Armatherm™ FRR thermal break material can support high loads of up to 40,000 psi and has an R value of 0.9 per inch, as well as great mechanical properties. 

As used within a number of prestigious, high-profile projects across the world, the Armatherm™ product range includes the innovative FRR material which harbors inert and water resistant qualities. This makes it ideal for a number of applications and locations, including cladding fixings, foundation to wall transitions, column base and roof penetrations. 

With more legislation changes coming into play each year to protect the future of the construction industry, Armatherm™ can be used in renovation projects to rectify a number of poorly isolated connections within existing buildings, as well as structures under construction to make them as efficient as possible. To achieve this and work towards making any building as efficient as possible, these solutions need to be considered within the earliest stages of a construction project, which is why it’s imperative for architects to understand the importance of these products and how they can help a structure meet certain efficiency criteria.

The FRR product specifically, is a structurally sound high performance thermal break material which delivers thermal insulation between interior and exterior steelwork, and / or concrete, to prevent thermal bridging. It can help work towards improving building envelope performance, dramatically reducing heat loss and preventing surface condensation from forming inside the building that can be caused by cold transfer meeting warm air. Structural thermal break concrete connections are at high risk of making a building inefficient so it’s imperative that solutions are considered. 

With its durable, long-lasting and cost-effective properties, along with lower repair and maintenance costs, concrete is often widely specified within the building industry. Although concrete naturally provides a high level of thermal mass, which enables it to absorb, store and release heat to regulate a building’s temperature, a simple penetration through the material or the presence of another can cause a thermal bridge. Should this occur, it will hugely impact the energy efficiency of a building as well as increasing its running costs, resulting in an inefficient and uneconomical structure. When working with such materials, structural steel thermal breaks must be at the forefront of plans to ensure all the framework, foundations and building envelope is as efficient as possible. 

When using structural thermal break pads in a parapet roof location, the U value of the roof assembly will be improved, and the potential chances of condensation problems occurring will be prevented at the structural connection. The FRR and 500 series thermal break materials can transfer the loading conditions in these applications while simultaneously reducing heat flow significantly, creating continuous insulation. The efficiency of these locations can be improved by as much as 80% which is invaluable in light of legislation updates and changes.
