Deceuninck Aluminium has launched the Decalu88 aluminium entrance door which uses a patented thermal stress control system to all but 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’.

He said: “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.

“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.

Nigel continued: “You have to look at what this door has been tested to: 80°C – not Fahrenheit – and even then, it only moves 2.5mm. In the temperatures ranges we get here in the UK – you’re not going to notice any movement.

“That’s a real plus for installers, which is why the Decalu88 is also going to generate opportunities for fabricators. The U-values are great, you can go big, there’s a flush option – everything you’ want in an entrance door is there.”

The launch of the Decalu88 Entrance Door follows that earlier this month of the Decalu163 Lift-and-Slide, which can accommodate sash weights of up to 400kg, and with single, twin and triple-track options.

The Deceuninck Aluminium range also includes the Decalu88 Aluminium Bi-folding Door, which accommodates individual sash weights of 200kg.

Deceuninck Aluminium also offers a series of casement options including Decalu 88 Steel and New Steel, designed to replicate steel commercial windows; plus a hidden sash and retro option. There’s also a turn-and-tilt option and the ultra-energy efficient, Decalu101 Scand.

Offering manufacturing efficiencies of up to 40% and with lower stock holding, the Decalu range is supplied in dual-colour, textured finish options and marine grade as standard.
