In steel stud construction, insulation is friction-fitted into stud cavities prior to applying the interior finish. Kraft facings are combustible; do not use in exposed applications. Check local code requirements.
In steel stud construction, insulation is friction-fitted into stud cavities prior to applying the interior finish. Foil faced products used in wood stud construction should be stapled approximately every 8" (200mm) with the vapor retarder facing the conditioned space. Foil facings are combustible; do not use in exposed applications. Check local code requirements. FSK-25 In steel stud construction, insulation is friction-fitted into stud cavities prior to applying the interior finish.
Faced products used in wood stud construction should be stapled approximately every 8" (200mm) with the vapor retarder system facing the conditioned space. For most applications, stapling and/or friction-fitting is all that is required. Consult your architect for specific vapor retarder requirements.
These installation recommendations are general in nature. Other methods are acceptable. Please consult local building codes for recommendations best suited to the application.
