Lifelines weigh less

Spider, a division of Safeworks LLC, has released its 25- and 50-foot self-retracting lifelines that weigh 14 pounds and 19 pounds, respectively. Despite weighing less than other self-retracting lifelines of the same lengths, the products, which contain galvanized steel cables, are said to be as durable as heavier lifelines.

Roof system combines materials

GAF Materials Corp. has made available its TriPositeXL™ Extra-Long Life Roofing System. The system features polyisocyanurate insulation with a fiberglass facer that is said to eliminate warping and provide mold and wind-uplift resistance. Asphaltic waterproofing layers, which are available in built-up and modified bitumen versions, reportedly eliminate blisters between the insulation and base sheet. And a single-ply, fleece-backed weathering membrane, which is available as a TPO or PVC membrane, is said to provide puncture resistance and be durable against foot traffic and debris.
