Introducing the ThermalBlock Series - Our Most Energy-Efficient Roof Hatch.
High-performance building enclosures deserves the best in roof hatch openings whether you are in Zone 1 or Zone 8. The ThermalBlock (RHTBA) Series of thermally broken roof hatches provides an energy-efficient solution to reducing building energy costs with an R value of 20.
- The durable construction and finish are designed to withstand heat, cold and UV exposure.
- 3” of polyisocyanurate insulation in both the curb and cover give the roof hatch a thermal resistance of R-20.
- Continuous gasketing maintains an air barrier and provides a thermal break between the curb and flashing.
- Counterbalanced lid and easy-to-operate handle allow one-handed operation.
