ThermalTight combines two essential building envelope materials into one: Neopor® GPS semi-vapor permeable rigid insulation by BASF, and a high-performance WRB laminated to the exterior of the panel, that acts as both a water and air barrier.  ThermalTight is typically more cost effective than a traditional WRB wrap paired with a separate insulated panel. 

The self-gasketing, vapor permeable WRB features a patent-pending flap system to eliminate the “reverse shingle” common with panel systems that require taping on top of seams. By adhering it to the outside of the rigid foam, ThermalTight creates one of the most effective air & water barriers for the building envelope.

With one less trip around the building envelope, ThermalTight makes it possible to manage water, air, vapor and thermal all in one panel. The different vapor permeability of the layers help manage moisture flow, allowing the wall to dry at a controlled rate. Integrates with ThermalBuck for true continuous insulation.
