The technology we developed in the insulating refrigerator door construction has been transferred to the insulating sectional door's one, gaing energy saving that before was unimagined, even due to the low thermic transmission coefficient we obtained (K = 0,338 W/sqm°C).

Therefore the panels, consisting these doors are produced with a foaming process by which the polyurethanic resins, injected under a warm press, will perfectly adhere to the external sheets (even galvanized even aluminium) becoming as a just one thing.

Upon request it is possible to provide the door with portholes or completely glazed parts.

Depending on the breastplate available above the door, different lifting system are adopted.

All DIMA FROID sectional doors are perfectly balanced and can be easily used manually. The motor unit is suggested where several door opening operations are required. It is even possible to provide the sectional with a small hinged service door outwards openable.
