The laminate is coated, on both planar surfaces (46, 47), with sheets (48) highly reflective of radiant thermal energy. The door material is incorporated in a system providing a rapidly acceleratable and deceleratable reel (12) and drum onto which the door material is rolled as the door is opened. The driving system (14) of the reel includes position sensing apparatus and braking apparatus. The door system also includes sensing devices (16) to detect a vehicle, a vehicle blocking device (18) to preclude impact on a closed door, and a control system to open the door and vehicle blocking device appropriately to allow the vehicle to pass through the doorway. Alternate embodiments of the door material are provided with horizontal guide bars (51) or with a security mesh (56) embedded in the door material.
