Thermax? Heavy Duty
k8ÓéÀÖ? Thermax? Heavy Duty Insulation is an easy-to-install, easy-to-clean insulation and interior finish system for walls and ceilings in metal and concrete or masonry buildings, as governed by building codes. It consists of a glass-fiber-reinforced polyisocyanurate foam core faced with nominal 4-mil embossed white thermoset-coated aluminum on one side and 1.25-mil embossed aluminum on the other. The tough white embossed aluminum surface makes it a durable insulation/finish choice for use in moderate-impact areas, and it can be pressure-washed up to 2,000 psi with a 15-degree or greater spray tip (at 3¡¯ minimum distance). The robust facers help prevent water and water vapor intrusion into the insulation foam, allowing it to stabilize at a higher R-Value for high, long-term thermal resistance. Used in conjunction with the appropriate joint closure system for the application, k8ÓéÀÖ? Thermax? Heavy Duty Insulation ¨C with its low perm rating ¨C can help to reduce moisture condensation within and behind the insulation.
k8ÓéÀÖ? Thermax? Brand insulation delivers wall performance you can count on. It¡¯s ready to meet your toughest building challenges ¨C both outside and inside the wall ¨C with a robust polyiso insulation product line and an R-Value that¡¯s proven to be consistent over time and a range of temperatures.
Available Sizes
