How it works    

Screws and plates provide thermal bridges across insulation systems - a significant problem associated with mechanically attached insulation assemblies. Thermochec insulates screws and plates eliminating thermal bridging.

The Thermochec system consists of factory laminated insulation boards with the top board having 6" diameter plugs removed for fastener placement.

 

Once the fasteners are applied, the plugs are then adhered in place with Thermochec adhesive effectively isolating the fastener and plate, eliminating thermal bridging problems. Thermochec also provides protection for the waterproof membrane from fastener back out and the sharp edges of plates.

Why Thermochec is better  

In mechanically attached systems, the insulation stress plate and the steel fastener (both excellent conductors) become "heat sinks" through the system, conducting heat to the cold surface of the roof and exposing cold fasteners to the underside of the steel decking inside the building. The resulting cold spots inside the heated space, attract condensation and consequent corrosion of fasteners and decking, to say nothing of the actual heat loss.

Considering Factory Mutual's increased density of fastener placement in corners and around the

 

perimeter, this can be a significant problem. Fastener density will vary dependent on on parapet height, building height, exposure, topography, ground roughness, and wind isotach readings for the area.

With this in mind, a system that eliminated thermal bridging for insulation securement, would be extremely beneficial to the thermal performance of the insulation assembly, and would further, effectively stop the condensation problem.

Thermochec Features and Benefits:

  • Top portion of the insulation assembly has 6" diameter plugs removed for fastener placement.
  • Fasteners are applied and plugs are adhered in place with Thermochec adhesive.
  • Eliminates condensation on fasteners and decking.
  • Protects the waterproof membrane from fastener back-out and the sharp edges of plates.
  • Stops heat from escaping through the metal fastener.
  • Protects the membrane over the fastener from foot traffic.
