2" thick insulated “sandwich”
construction consists of exterior and
interior steel skins pressure bonded to
an environmentally safe polystyrene core
for greater strength and quieter operation.

Sectional R-value 9.1

Both steel skins are separated by a continuous
silicone filling to form an efficient thermal break

Tongue-and-groove section joint for exceptional strength
and thermal sealing
Virtually maintenance-free because of Clopay’s three stage
rust-proofing and prepainting process

Superior dent resistance and greater
security are provided by a full 24 gauge
exterior steel skin
