Products & services
Recycling plant Diksmuide
We have been committed to recycling our PVC products for many years. That is why we built our recycling plant in Diksmuide back in 2012. We are therefore delighted that customers are attaching increasing importance to recycling and sustainability. Through our recycling activities, we directly contribute to preventing waste from ending up in landfills or being incinerated. Thanks to these efforts, we avoided the emission of 45,000 tons of carbon equivalents in 2024. This is equivalent to 2.9 million windows that we save from incineration and give a new life. We collect and recycle PVC material from window and door manufacturers and installers worldwide. This so-called pre-consumer material consists of offcuts and cutting waste that are generated before the product reaches the customer.

Elegant: windows and doors in PVC
Elegant: the window profile for those who value both aesthetics and performance With Elegant, Deceuninck proves that plastic profiles also fit perfectly with contemporary, modern architecture. The frame has a sleeker design and is available in two installation depths: a 76 mm and a 115 mm version. Depending on the desired style, the frame can be combined with different wing designs. The Origin offers a solution for those who like a classic, rural or rectory style. The Abstract offers an extremely minimalistic appearance and Infinity a very subtle transition from profile frame to wing. The wing can be recessed or flat, and the latter is unique for plastic profiles. Rectangular instead of rounded glazing beads further contribute to the sleek look. Although plastic already excelled in terms of thermal and acoustic performance, Deceuninck also went a step further here. The Infinty wing is also available in a ThermoFibra version. The standard steel reinforcement makes way for structural glass fibres that are already introduced during the extrusion process. The result? Profiles with the same stability, but better thermal and acoustic performance. The frame profile in turn received a thermal reinforcement based on steel wire reinforced PVC hard foam to further improve the insulation values. “In combination with this frame, Elegant ThermoFibra is the best working steelless plastic window and door solution on the market. The ThermoFibra Infinity wing can achieve a Uf value of 0.88 W/m2K together with a standard fixed frame. It carries the Passive House certificate.
Decalu aluminium windows and doors from Deceuninck
Our years of experience with plastic profiles were applied in the development of the Decalu aluminium series. These 3 central pillars make the Decalu aluminium series unique. Excellent technical performance The integrated thermal insulation and optimised centre closure ensure high performance values from 0.96 W/m²K across all designs. All existing seals are applied during the production process instead of on site. This ensures optimum and even placement and consequently better performance in terms of wind and water tightness. Our sustainable coatings are available in any RAL colour and are always Qualicoat class 1 certified. Focus on design Several design options are available and have been worked out down to the smallest detail. For example, the seals have been reduced to a minimum width and optimally placed for minimum visibility. Decalu profiles have the smallest visible width for maximum light incidence without sacrificing performance. The entire range is equipped with concealed hardware as standard. The drainage is invisible without the use of cover caps to hide the drainage channels. User-friendly The Decalu range is compatible with various high-quality hardware brands for effortless operation of your (sliding) windows and doors. Our Decalu doors have an integrated anti-bi-metal technology to prevent deformation. This way, your front door closes perfectly in every season! The concealed hardware and high-quality coatings make the maintenance of your aluminium windows and doors a lot easier.

WinLinck: fast, efficient and circular
Deceuninck unveils its latest innovation: WinLinck, a modular installation method with a click system specifically developed for modular construction. With WinLinck, installers can easily click windows into the opening without the use of foam. The system is assembled off-site in a controlled environment, after which the window is clicked into place on the construction site. WinLinck is more than just a window or click system—it is a new way of building windows. With WinLinck, Deceuninck once again takes a step towards a more sustainable and efficient construction sector.
