Insulating roofing barrier STRATHERM®

HPVpolypropylene

STRATHERM® is a roof underlayment HPV (High Permeability to water Vapour) with thermal insulation reinforcement. It is a roof underlayment and radiant heat shielding. DESCRIPTION STRATHERM® can be laid, either directly on insulation, either onto discontinuous support with a non- ventilated air space, underneath. Its intrinsic thermal performances combined with its metallic faces, will increase the buildings thermal insulation and improve summer comfort. Advantages: STRATHERM® is laid in compliance with standards and DTU in force as well as installation rules for certified flexible roof underlayments (CSTB notes N° 3651- 2 of January 2009). STRATHERM® is unrolled, parallel to the gutter line with 10 cm overlapping, by using the upper tongue for slope > 30%. If slope is ≤ 30%, it's necessary to make a suitable sealant bead under the upper tongue. STRATHERM® is a symmetrical product to optimise cuts, waste as well as installation time. For example, an oblique cut used for valley can be reused above, simply flip the product. STRATHERM® is easily cut with a utility knife (for more safety, use a snap- off knife).
