Rigid Insulation With Plywood Sheathing

3 benefits of rigid foam sheathing.

Rigid insulation with plywood sheathing.

Keep in mind that any interior rigid insulating panel must be covered by a barrier. 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. 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. Comfortboard 80 is an exterior non structural insulation sheathing that provides a continuous layer of insulation around the commercial or residential building envelope. The glass fiber reinforcement contributes to improved fire performance and dimensional stability. Featuring integrated moisture air and thermal protection zip system r sheathing completely reimagines traditional wall assemblies by streamlining exterior water air and thermal management.

1 inch and 2 inch thicknesses are common. A common choice is drywall. For these products the permeance will not change with increasing thickness. Plywood has an r value of 1 25 and fiberglass batts have an r value of 3 14.

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. Continuous rigid insulation is a construction solution that provides a thermally efficient building enclosure. 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. Rockwool comfortboard 80 is a rigid mineral wool insulation sheathing board that is non combustible water repellent fire resistant and sound absorbent.

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. Omega ci is available in 4 x 8 sheets in 2 1 thickness contact laminators technical support for alternative thickness availability. The boards are available in several thicknesses and r values. Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding.
