Rigid Insulation With Plywood Sheathing

3 benefits of rigid foam sheathing.

Rigid insulation with plywood sheathing. Featuring integrated moisture air and thermal protection zip system r sheathing completely reimagines traditional wall assemblies by streamlining exterior water air and thermal management. A common choice is drywall. R panel is manufactured with a closed cell polyisocyanurate foam core bonded to fiberglass reinforced facers and designed for use over metal nailable and non nailable roof decks with a variety of membrane systems. The panels provide a continuous energy efficient surface.

Keep in mind that any interior rigid insulating panel must be covered by a barrier. 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. Follow with a 2x4 frame wall and insulate it with batt insulation. The boards are available in several thicknesses and r values.

The glass fiber reinforcement contributes to improved fire performance and dimensional stability. Omega ci is available in 4 x 8 sheets in 2 1 thickness contact laminators technical support for alternative thickness availability. Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding. More effective insulation with r values ranging from 3 6 to 8 0 rigid foam sheathing has much better insulation per inch than other materials i e.

Comfortboard 80 is an exterior non structural insulation sheathing that provides a continuous layer of insulation around the commercial or residential building envelope. Omega ci is a rigid insulation panel comprising a closed cell polyiso foam core bonded to a premium performance coated glass backer and a 5 8 fire treated plywood face. 1 inch and 2 inch thicknesses are common. Johns manville r panel rigid roof insulation board offers r values of up to r 23 6 providing high thermal efficiency.

Zip system r sheathing is the simple all in one structural panel with built in exterior insulation. For these products the permeance will not change with increasing thickness. Rockwool comfortboard 80 is a rigid mineral wool insulation sheathing board that is non combustible water repellent fire resistant and sound absorbent. For faced rigid insulation boards such as foil faced or glass fiber faced polyisocyanurate the permeance of the facing is often much lower than the permeance of the polyisocyanurate and will govern the overall permeability of the sheathing board.
