ARMATHERM™ Thermal Envelope Solutions
Thermal bridging through steel and concrete framing can have a significant impact on a building’s energy performance. Reducing heat flow within a building’s thermal envelope reduces energy consumption in addition to eliminating potential condensation problems.
Armadillo Structural Connections group has developed Armatherm™ thermal break materials that significantly reduce the amount of energy lost from thermal bridging in structural steel and façade connections and improve building envelope performance by helping to meet ASHRAE 90.1 energy code compliance.
Armatherm™ FRR and Armatherm™ Series 500 thermal break materials can be used anywhere a penetration or transition exists in the building envelope creating a thermal bridge. Solutions using Armatherm™ to minimize heat loss include balcony, canopy, parapet, masonry shelf angle, cladding/ Z-girt and curtain wall mullion connections. Improvements in the effective U value of wall assemblies can be realized by as much as 60-70%.
ARMATHERM™ Minimize building energy loss and improve building envelope performance.
Armatherm™ FRR, Structural Thermal Break Manufactured for exceptionally high compressive loads to give zero deflection in service. FRR is to be employed in high force connections or large cantilever arrangements.

ARMATHERM™ FOUNDATION TO WALL TRANSITION THERMAL BREAK
Armatherm™ 500 series material can support and transfer loads up to 17N/mm2 (2,500 psi) while providing minimal energy loss. When used with Armatherm™ rebar, the heat loss at these concrete connections is reduced significantly. Foundations are a part of a building’s envelope. The connection from slab on grade to foundation wall and wall above foundation wall transition are both areas where thermal bridging occurs. Additionally, if the lower level of a building functions as an uninsulated storage or parking area, the support columns or pile caps connecting the base slab to the first floor also create a thermal bridge.
Columns traditionally extend through the building envelope and slab insulation at their base. Thermal bridging can be prevented by using Armatherm™ 500 series material as a load supporting, thermal break directly under the column base. This is particularly important in cold storage facilities to prevent the sub grade from freezing.
Cold bridging through a single masonry support bracket might be quite small, however when multiplied by the number of connections on a building the energy loss can be a concern. Armatherm™ BWS pads offer a quick solution to this problem.
Energy costs are only set to increase, keep the heat in the press in the right place. With a continuous running temperature of 500°C (930°F) and a compressive strength of 360 Mpa (53 KPI) Armatherm™ Mica 500 Asbestos Free Press Platten Insulation material is THE solution.
Roof to wall and parapet locations require structural framing for support which prevents continuous insulation from roof to façade. This creates a thermal bridge which can be prevented by providing an Armatherm™ 500 series structural thermal break under the parapet connecting the façade and roof insulation and improving the effective R value by as much as 30%. A thermal break can also be installed within the envelope at roof penetration points where structural elements are supported.
