Rigid Insulation With Plywood Sheathing

The panels provide a continuous energy efficient surface.

Rigid insulation with plywood sheathing.

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. Continuous rigid insulation is a construction solution that provides a thermally efficient building enclosure. 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.

Follow with a 2x4 frame wall and insulate it with batt insulation. 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. Omega ci is available in 4 x 8 sheets in 2 1 thickness contact laminators technical support for alternative thickness availability. Featuring integrated moisture air and thermal protection zip system r sheathing completely reimagines traditional wall assemblies by streamlining exterior water air and thermal management.

The glass fiber reinforcement contributes to improved fire performance and dimensional stability. 1 inch and 2 inch thicknesses are common. 3 benefits of rigid foam sheathing. A common choice is drywall.

The boards are available in several thicknesses and r values. Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding. Rockwool comfortboard 80 is a rigid mineral wool insulation sheathing board that is non combustible water repellent fire resistant and sound absorbent. For these products the permeance will not change with increasing thickness.

Rigid insulation sheathing is made of a rigid plastic foam that is typically sold in 4x8 or 4x10 foot boards. Zip system r sheathing is the simple all in one structural panel with built in exterior insulation. 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. Plywood has an r value of 1 25 and fiberglass batts have an r value of 3 14.
