Thermally broken roof hatches reduce heat transfer between interior and exterior surfaces to resist condensation. The units are available in standard and custom single-leaf sizes and provide polyisocyanurate insulation (R-20+) for superior energy efficiency. Products include a thermally broken cover and curb and have corrosion-resistant aluminum construction. The hatch comes with a slam latch with interior and exterior turn handles and padlock hasps. Compression-spring operators in telescopic tubes provide lift assistance. An automatic hold-open arm with grip handle release is also included.
