Is R-tech waterproof?
R-TECH® Rigid Foam Insulation In addition, R-Tech has excellent dimensional stability, compressive strength and water resistance properties.
What R-value is R-Tech?
InsulFoam EPS has R-values that vary depending on temperature and the density of the product installed. For instance, our standard R-TECH, sold in home improvement stores, has an average R-value of about 3.9 per inch at 75°F.
What is ISO board roof insulation?
Polyisocyanurate thermal insulation, also referred to as polyiso, PIR, or ISO, is a popular low slope commercial building roof insulation. It is a thermoset, closed-cell foam that is an optimal insulation solution for low slope roofs. It can also be used as a roofing cover board and in building envelope applications.

What is R-Tech made of?
R-Tech is a high-performance, rigid insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers. R-Tech is available with factory laminated metallic reflective facers, white facers or a combination of the two.
Which side of R-Tech faces out?
If you’re wondering whether to put the foil side of foam insulation board shiny side in or out, consider whether you want to make the space inside warmer or cooler. If you want to make the space warmer, the foil should face inside so it can reflect radiant heat back into the room.
How good is polyiso insulation?
Polyiso is stable over a large temperature range (-100°F to +250°F) and can be used as a component in roof systems utilizing hot asphalt. Polyiso has low density, good adhesion to facers, low water absorption and low vapor transmission.
What is the R-value of ISO board?
For the R-value of polyiso wall insulation, a full thickness, 180 day aged value is recommended. Foilfaced polyiso has an R-value of about 6.5 per inch and permeability faced polyiso wall insulation has an R-value of around 6.0 per inch.
Which side of R Tech faces out?
Does R tech insulation work?
The core of R-Tech is the same high-quality EPS as our InsulFoam insulations and meets or exceeds the requirements of ASTM C578 Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. R-Tech has excellent dimensional stability, compressive strength and water resistance properties.
Can InsulFoam get wet?
properties will remain stable over its entire service life. There is no thermal drift, so the product is eligible for an Insulfoam 20-Year Thermal Performance Warranty. surface that is virtually impervious to moisture. manufactured with an inert additive that deters termites and carpenter ants.
Is InsulFoam waterproof?

Which way does foil backed insulation go?
The foil insulation goes on top of the moisture barrier, followed by the roof covering. If you use bubble foil or rigid foam insulation, it also goes on top of the moisture barrier. Remember that there has to be an air space between the foil and the roofing.
Is polyiso waterproof?
Polyiso and extruded polystyrene foam boards have the strongest waterproof properties.
