Dow Polyisocyanurate Cavity Wall Insulation

Polyiso ci commercial wall construction.

Dow polyisocyanurate cavity wall insulation.

Tuff r polyisocyanurate insulation consists of high performance high r value closed cell polyisocyanurate foam core boards sandwiched between a choice of durable exterior foil facers. Wall and ceiling overview. Foil faced polyiso products have higher long term r values compared to other rigid board products. Thermax sheathing can be installed exposed to the.

Thermax sheathing specially designed to hold a class a fire rating. R means resistance to heat flow. Foil is a vapour barrier and a very good one at that it fact it stops even more moisture than the normal 6 mil polyethylene normally used. Polyiso is the best insulation for cavity wall applications.

Thermax sheathing is a non structural rigid board insulation consisting of a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum facers on both sides. Pour in place insulation spray insulation polyol blends compatible with polyester and polyether polyol formulations the surfactants simplify the mixing of polyols and blowing agents maintain the blowing agents in the emulsion or solution and provide excellent emulsion stability. Ask your seller for the fact sheet on r value. The other is a tri plex facer consisting of a three ply laminate of durable kraft.

Rigid insulation comes in panels of various thickness which provide different r values. The glass fiber reinforcement contributes to improved fire performance and dimensional stability. For more than 35 years rmax has been creating insulation solutions based on the latest building science. Polyisocyanurate foam insulation panels come with a layer of foil on each side to keep the gases in so there is the potential to solve a bit of a growing problem in wall assembly durability.

The higher the r value the greater the insulating power. The glass fiber reinforcement provides improved fire performance and dimensional stability. 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. Thermax sheathing is a nonstructural rigid board insulation with a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum faces.

Continuous insulation provides improved performance compared to typical cavity insulation by creating an uninterrupted thermal barrier across the wall. Specify polyiso for cavity wall applications. Our full line of high quality polyiso based wall and specialty insulation products for commercial residential and industrial applications deliver maximum r values and minimum environmental impact with efficiency in installation cost and design. We offer dow thermax polyisocyanurate and dow styrofoam xps extruded polystyrene known as blue board.

Easy to work with rigid insulation can be incorporated into construction or added later to increase r value. On tuff r insulation one facer is a continuous sheet of aluminum foil. The unparalleled performance of continuous insulation results from the reduction of thermal bridges created by wall framing members.
