Deceuninck Aluminium has added a slim-interlock option to its ultra-energy efficient Decalu163 Lift-and-Slide aluminium patio door.

The heavy-weight system can accommodate individual sash weights of as much as 400kg and achieves u-values of as low as 0.8 W/m2K triple glazed.

Now available with a slim 53mm interlock, Nigel Headford, Deceuninck Aluminium’s Business Development Director, said the Decalu163, was primed to support fabricators and installers in capitalising on the boom in home improvement.

“Lift-and-slide products are seeing resurgent demand as part of the Lockdown-driven boom in home home improvement”, he said.

“Straightforward to manufacture, with only minimal investment in tooling required, and easy to install, the Decalu163 is now available with a slim 53mm interlock option increasing homeowner appeal, making it an instant win, for fabricators and installers.”

Launched as part of Deceuninck Aluminium’s expanding offer the Decalu163 Lift-and-Slide is available in single, twin and triple-track options.

In common with the the Decalu88 Bi-Fold and its wider window and door range, the Decalu163 is supplied in dual-colour, textured and marine grade finishes – as standard.

It also features the same high performance pre-inserted flush gasket and advanced thermal-breaking technology, used by Deceuninck Aluminium across the Decalu window and door range, guaranteeing thermal efficiency and weather sealing.

“If you can manufacture a product that has proven appeal with installers, for minimal investment and stockholding, why would you buy in?”, Nigel said.

“You can manufacture the entire Decalu range, that’s the Decalu163 Lift-and-Slide, Decalu88 Bi-fold, French and residential door, and the window range on one set of tooling. Highly modular, you don’t need to tie-up cash in stock and manufacturing times are 40% faster.

“Most importantly, it’s a product range that as a fabricator – or installer – your customers want!”
