The ThermalBlock thermally broken roof hatch provides superior energy
efficiency with R-20 insulation in both curb and cover which reduces
condensation and building energy costs.
How Does the ThermalBlock System Work?
Two continuous
gaskets with low thermal conductivity create a thermal block between the outside
and the inside. When the weather outside is colder, this combination of
insulation and gasketing moderates the temperature on the inside of the roof
hatch reducing condensation and icing. The roof hatch can also reduce the amount
of heat transferred from a warmer exterior, keeping air conditioning costs
lower.
Manufactured from 11 gauge aluminum, mill finished. The durable construction
and finish are designed to withstand heat, cold and UV exposure.
