Insulation roof sheeting.

Insulated roof panels are an ideal roofing solution for anyone looking to benefit from lower running costs straightforward maintenance and upfront cost effectiveness. There are at least two good reasons why this approach makes more sense than installing the insulation under the roof sheathing. They re much lighter and easier to work with than plywood sheets. In warm climates zones 1 through 4 low density open cell spray foam insulation is the typical choice since it is vapor permeable and will allow drying of the exterior sheathing and roof framing if they happen to get wet via diffusion into the interior of the building.

For new construction use rigid boards to insulate slabs and the outside of foundation walls. Foam board sheathing insulation johns manville polyiso foam sheathing insulation boards provide a continuous layer of insulation to reduce thermal bridging and improve energy efficiency. If there is a roof leak the insulation will be damaged by the water leaving you with less insulating value. Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away.

For the same reason insulation shouldn t touch the roof s underside. The moisture is held in place by the insulation which allows for damage to the framing and other building components. 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. Foamular 150 1 in.

Polyiso consists of a uniform closed cell polyisocyanurate foam core and provides one of the highest r values per inch of any rigid insulation. The problem with the insulation against the sheathing expands. 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 airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.

Zip system r sheathing is the simple all in one structural panel with built in exterior insulation. Working with home insulation boards insulation panels typically come in 4x8 foot sheets. Install them using panel adhesive or screws. Insulated roof panels have all of the advantages of regular roof sheets but have an added layer of refinement and efficiency that ordinary panels do not have.
