T-shaped batt of insulation - has U=shaped vapour barrier extending beyond longitudinal ends of batt for connecting consecutive batts

摘要

This T-shaped batt of insulation with a U-shaped vapour barrier covering the lower surface of the batt. The vapour barrier covering the lower surface of the batt. The vapour barrier extends beyond the longitudinal ends of the batt. Consecutive batts are connected by folding adjacent vapour barrier extensions upwardly, and connecting these extensions in any suitable manner. The T-shaped batts are formed either by notching out the edges of the batt using a high speed saw or by attaching a wider piece of insulation on top of a narrower one. The batts of insulation fit between parallel support members however the narrow horizontal flanges or adjacent T-shaped batts overlap on top of the support members and are retained by a covering panel.
