Exterior Sheathing Insulation Prettier

Insulation sheathing membranes rely on tape to complete the air barrier.

Exterior sheathing insulation. Extruded polystyrene foam insulation like styrofoam brand residential sheathing is inherently resistant to moisture which can wreak havoc on other building materials. For the rigid insulation to be used as a water resistive barrier the vertical plane of the exterior face of the sheathing must be as smooth and continuous as possible. However most structural exterior wall sheathings lack insulation value.

This concept while not new has become more accepted in recent years and is being used in residential construction. This concept while not new has become more accepted in recent years and is being used in residential construction. The tapes should be applied on a clean dry warm surface.

Structural sheathing and non structural sheathing. Moisture can compromise the performance of cavity insulation and damage drywall wood framing and osb or plywood sheathing. Non structural exterior wall sheathing also prevents intrusion of either water or wind and in some cases it acts as a radiant barrier.

R matte rmax r matte plus 3 1 2 in. Exterior sheathing can be loosely grouped into two categories. Adding one inch of insulating sheathing r 5 will increase a 2 x 6 stud wall from an.

Best of all they are waterproof and eliminate the moisture retention problems of conventional sheathing. 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. The glass fiber reinforcement contributes to improved fire performance and dimensional stability.

Non structural exterior wall sheathing works with the building s envelope to provide added insulation. Adding insulating sheathing to the exterior of the assembly is a simple method of increasing the overall thermal resistance of the wall assembly beyond what is possible with cavity insulations thereby increasing the overall efficiency of the house.
