New aluminium entrance door range

Deceuninck Aluminium has launched the Decalu88 aluminium entrance door, which uses a patented thermal stress control system to help eliminate bowing.

It means that the new Decalu88 entrance door offer is supplied with a guaranteed maximum bowing tolerance of only 2.5mm in temperatures up to 80°C and deflection of as little as 3.5mm in temperatures as low as -30°C.

Nigel Headford, Deceuninck Aluminium’s business development director, said the minimal movement in the door under extremes of thermal stress “re-wrote design convention”.

“Movement in a door-set under temperature change is a nightmare for installers because you can’t legislate for it when you’re setting the door,” he said.

“The patented mechanism used in Decalu88 minimises bowing in the door under heat or cold, which means the design constraints don’t apply. You can have a dark colour on a south facing elevation. It’s not a problem.”

The range includes a choice of 30 contemporary aluminium insert panels, plus 21 flush finish options, each using the same composite thermal break technology.

This uses special ABS inserts within the thermal break, which adapt to temperature change allowing the internal and external faces to expand and contract independently of one another limiting bowing to a maximum of 2.5mm, even in extreme heat.

U-values on the Decalu88 panel entrance door are as low as 1.1W/m2k. Maximum sash weight is 150kg.
