JL Industries is now offering a redesigned line of steel and aluminum roof hatches that provide higher insulation value, easier installation, and improved cover operation. The new Diamond™ Series is designed to reduce energy costs with R-6 polyisocyanurate insulation in both curb and cover, which exceeds IECC requirements of R-5 for curbs. A one-handed latch opening for ladder access and counter-balanced lid provides the functionality and safety that building owners are looking for to comply with OSHA fall protection. Installation is easier with the new Diamond Grip™ feature that secures the roofing membrane and backer rod without special tools.
The Diamond Series replaces the RHG and RHA series that has been offered for the last 22 years by JL Industries, and will be available in seven standard sizes and a full range of custom sizes. Double wall and higher R-Value curb insulation are optional features for this new series. To reduce solar heat gain, the standard finish for steel models is a durable, textured, IR-reflective white powder coat finish. The hatches meet industry wind uplift standards of 50 psf and support a live load of 40 psf. When ordered with JL Industries’ compression-fit railing system and self-closing rigid gate, the roof hatch meets the new OSHA standards for protection of workers on walking/working surfaces.
