Foil roof sheathing.

Johns manville ap foil faced polyiso foam sheathing boards are available in r values up to r 28 and offer a reflective foil facer on one side and a non reflective facer on the other. The rigid board sheathing has a one inch layer of continuous insulation for maximium wall and worksite efficieny. As an added plus weyerhaeuser rbs can even help keep non air conditioned uninsulated rooms like garages workshops and porches cooler increasing a home s usable space. Radiant barrier roof sheathing is a great product that will reduce your power bill.

Foil backed osb is applied mostly in attics. The goal of a foil backed osb is to cool the air within the top layer of insulation in the attic or wall by emitting the radiant heat absorbed through the roof or exterior walls which reduces the delta t and lessens the overall energy use in a building. However it is also used in wall systems. Ap foil provides exceptional heat moisture and air control and when installed correctly eliminates all major thermal bridges that cause heat loss.

Ap foil provides exceptional heat moisture and air control and when installed correctly eliminates all major thermal bridges that cause heat loss. Oriented strand board osb with a thin layer of low emitting aluminum foil attached to one side is a common type of thermal radiant barrier sheathing. Rbs radiant barrier sheathing weyerhaeuser radiant barrier sheathing rbs comes pre fabricated with a reflective foil layer that reflects up to 97 of the sun s radiant energy minimizing heat transfer through the roof and insulation to interior living spaces. Foil insulation underlayment is recommended under a metal roof and in most cases the shiny side should be facing up but there s a catch.

Thermo ply is manufactured to withstand the most rigorous of job site conditions. 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.
