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.
