Armatherm™ 500

Armatherm™ 500 Structural Thermal Break Material

(Thermal Insulation Material – TIM)

Reducing heat flow within a building’s thermal envelope reduces energy consumption as well as potential condensation issues. Armatherm™ 500 thermal break material (TIM) significantly reduces energy lost from thermal bridging in building envelope connections. Armatherm™ 500 structural thermal break material is a high strength, thermoset polyurethane manufactured in several densities. Armatherm™ 500, made in the USA, is able to transfer a wide range of structural loads with a range from 20 psi – 4000 psi. Armatherm™ 500 has R values as high as 3.8 per inch which is superior to the properties of aerated concrete and wood blocking.

The Armatherm™ 500 thermal insulation blocks do not absorb water due to its closed cell structure, and has very limited creep under load. This helps reduce energy lost via thermal bridging pathways within building envelope connections, reducing heat flow, energy consumption and potentially dangerous condensation issues. The standard thicknesses Armatherm™ 500 is available in are 2”, 1” and 1/2”, but the high strength, polyurethane material sheets can easily be layered to achieve the desired U value and thickness specifications. It is very versatile and can be used anywhere that features a penetration or transition exit through a building envelope where a thermal bridge occurs and can be cut and drilled on site easily, if required. The most common specifications include Armatherm™500 150 and Armatherm ™500 200. Although it is often specified to prevent thermal bridging in buildings to reduce heat loss, Armatherm™500 is ideal for cold storage facilities to prevent the subgrade from freezing. It can sit directly under the column base to help prevent the transfer of cold temperatures into the ground, making it the perfect solution for frozen food storage.

Applications using Armatherm™ 500 to reduce heat flow include:

Armatherm™ – Parapet Roof Penetration Thermal Bridging Solution

Locations like roof to wall and parapets require structural framing for support which means thermal bridging is prevalent. They can be prevented by including thermal break materials under the parapet connecting the facade and roof insulation to overall improve the R value by as much as 30%. A thermal break can also be installed at roof penetration points where structural elements are supported, within the building envelope. 

Armatherm™ – Column Base Thermal Bridging Solution

Traditionally, structural columns extend throughout the building envelope and slab insulation at their base. Thermal bridging can be prevented with the addition of a thermal break, and Armatherm™ 500 is the ideal solution for load supporting thermal break requirements thanks to its limited creep under load and high strength.



Armatherm™ – Foundation Wall Thermal Bridging Solution

The foundations of a building are part of the envelope, and the connection from slab on grade to foundation wall and wall above foundation walls are both areas with the potential to feature thermal bridges. The addition of an Armatherm™ 500 series thermal insulation block can support and transfer loads of up to 2150psi, while helping reduce energy loss drastically. Armatherm 500-280 can be used in poured -in-situ balcony applications to greatly reduce heat loss at balcony connections.
