The Legalett ThermalWall PH Panel system is a simple and cost effective way of boosting the wall insulation performance of practically any building, be that new build or renovation to Passive House or Zero Net Energy (ZNE) building standards. The ThermalWall PH Wall Panel System is a Passive House Institute PHI Certified Component.
ThermalWall PH Wall Panel System is the perfect way to add insulation when trying to reach Passive House or Net-Zero standards. ThermalWall PH are Passive House Certified components for Cold climates by the Passive House Institute. View our Passive House Institute PHI Certificate here or the PHI Certification Report here.
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 insulation panel is taking the North American continuous exterior insulation market by storm…
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. But over the last few years it has become common for green builders to reject foam, especially as alternatives like rock wool became available.
ThermalWall PH Panels are installed on a 25,000 sqft manufacturing facility in Haliburton ON that is intended to be Passive House Certified. This facility already utilizes Legalett’s GEO-Passive super insulated slab and foundation forms.
