Passive House External Wall Insulation System

A simple, cost-effective exterior insulation solution for new builds and retrofits.

Our Latest Innovation for Passive House and Net Zero Energy Wall Insulation and ICF Construction

With a standard R-Value of 28, the ThermalWall PH Panel was specifically designed to raise the insulation levels of a building enclosure to those required for Passive House design or Net Zero Energy design (NZEB & ZNE).  Secured to the outside of any structure with virtually no thermal bridging, it can transform a code compliant R-24 wall into an R-52 high performance envelope.  This easy to install, well-designed EPS Foam passive house external wall insulation panel is taking the North American continuous exterior insulation market by storm…

ThermalWall PH Panel Wall and Ceiling External Wall Insulation Reviewed & Recommended by TreeHugger

It has been a mantra of TreeHugger that where possible, it is better to build foam free. Plastic foams are sometimes made with blowing agents that have serious global warming potential; they are made from known carcinogens and they are treated with toxic flame retardants. I have been called an idiot so many times by people who point out that foam insulation works really well and that it pays back the carbon and greenhouse gas footprint in short order.
