Babcock Davis 48×48 ThermalMax Roof Hatch

The Babcock Davis 48×48 ThermalMax Roof Hatch provides stair access to roof areas on your building while also insulating your home or business from the elements. The inside measurement of this hatch allows more room to bring up tools and equipment to the roof and meets the 16 Sq. Ft. requirement several states have now adopted. The ThermalMAX series sets the new standard for thermally efficient roof hatches. Designed with a thermal break to keep cool-cool and hot-hot, this hatch boasts an R-20 insulation rating making it today’s most energy efficient hatch. We also offer the safety railing for this unit to insure safe entry and exit from the roof with full OSHA compliance.
