Dutemänn agrees a new supply agreement with Deceuninck Aluminium

Aluminium door and window specialist, Dutemänn has agreed a comprehensive new supply-agreement with Deceuninck Aluminium. As part of the new partnership, Dutemänn will begin manufacture of its own uniquely designed variant of the easy-fit Decalu88 Bi-folding Door, which will be branded as Elän; and the Decalu 163 Lift-and-Slide, which will be sold under Dutemänn Glide product range.

Dutemänn will also begin manufacture of the complete Decalu window range including tilt-and-turn, fully reversible and new flush casement options which will be supplied under its Schärpe brand.

Martin James, Managing Director, Dutemänn, said that the ultra-low u-values achieved by Decalu across its range were instrumental in driving its’ decision to team-up with the aluminium systems leader. He told Windows Active: “Our customers are owner-driven businesses, with impressive, modern showrooms. They always have their own fitters (they wouldn’t sub-contract) and they tend to work in the architectural or self-build spaces. They are looking for quality and with 2025 and the Future Homes Standard on the horizon, they are also looking for great u-values.Deceuninck Aluminium and Decalu delivers that. It’s one of the very few aluminium systems that gets down to 0.8W/m²K, today. That’s going to be very important because window and door design is going to have to change – it already is.” 

Designed in the UK, flush inside and out, and with u-values as low as 0.8W/m²k triple-glazed – and 1.2W/m²k with a standard unit – Deceuninck Aluminium’s new Flush casement window epitomises the aluminium systems company’s approach.Launched in January 2023, it is, however, only the latest in a series of new product roll-outs which began with the Decalu88 bi-fold (u-values in this case go even lower to 0.68W/m²K).  

This was followed by the Decalu163 Lift-and-Slide; then the Decalu88 range of contemporary casements, reversible, tilt and turn, and heritage options – each delivering u-values low enough to comfortably meet whatever changes Part L and Future Homes delivers. Martin continued: “As with everything that Dutemänn has done over the years, we didn’t restrict ourselves to a UK centric search, we looked at what was on offer in Germany and in the Benelux countries – because they lead the way.  Deceuninck Aluminium is relatively fresh to the UK market but that didn’t concern us because the system is proven. What was important was that Deceuninck Aluminium was prepared to listen and to work with us as a genuine partnership. That has happened and more. It’s been 12-months in the making, but it’s been an absolute pleasure.” 

Set up in 2010 as a specialist supplier of aluminium bifold doors, Dutemänn has seen rapid growth to become one of the UK’s leading manufacturer’s of quality aluminium doors and windows. 

Nigel Headford, Director, Deceuninck Aluminium, said: “Dutemänn is a very high-profile fabricator with an established reputation for quality, service and innovation. It’s decision to partner with us, is built on those shared values and particularly the lead we have taken in the supply of energy-efficient aluminium windows and bi-folding, lift-and-slide and composite aluminium entrance doors. With the new Future Homes Standard around the corner, that assumes increasing importance.”
