A Layered Approach to Savings

Thermasheath®-SI Residential Solution for Exterior Walls

This revolutionary new structural insulated sheathing board combines a layer of structural stability with superior continuous insulation, an air barrier and a water barrier. Thermasheath®-SI provides continuous structural insulation across your entire wall to optimize design. Compared to OSB, this lightweight building product reduces time and cost in materials and labor. Being continuous insulation, it is the most effective way to insulate the envelope, reducing energy consumption and greenhouse gases. 

 

It makes sense

Why wrap the house more than needed? By combining a structural panel with an air barrier, water barrier and continuous insulation, Thermasheath®-SI puts the power of multiple building products into a single application. Therefore, one can reduce labor/installation costs while raising R-values, structural capacity and resistance to moisture and air infiltration. Doesn’t that make sense?

It Saves Cost

It’s easy to see how Thermasheath®-SI saves money during construction – it cuts down on the number of materials and trips around the house. It also saves money for homeowners with lower energy consumption through thermal efficiency. Don’t home owners want to save money month after month?

It Maximizes Profit

Combining Thermasheath®-3 in the field with Thermasheath®-SI as intermittent braced wall panels provides a total home sheathing solution. With a single application, builders can cut time and labor costs while maximizing margins, all in a code compliant package. Don’t you want to improve your bottom line?

 


The secret is in the layers.

Structural – Made up of 97% recycled content, the fiberboard layer is a lightweight, rigid structural layer designed for lateral bracing and transverse loads, including portal frames and seismic design.
Insulation – A high R-value polyiso layer that provides continuous insulation and meets the highest energy-efficient standards.
Air and Water Barrier – An impermeable foil facing that repels water and guards against air infiltration.
