Classic styling, modern PVCu performance

The Deceuninck 2800 PVCu system is one of the leading window and door systems on the market today. Built from Deceuninck, an industry name that you know you can trust, we use it to fabricate a range of high-quality PVCu windows and doors.

Thanks to a smooth, symmetrical profile, they are undeniably attractive, while multiple chambers offer superb performance, which is aided further by a multi-functional weatherseal that is welded at the corners. Available in a wealth of colours and with complementary trims and accessories, this flexible system is an excellent choice for a wide range of traditional and contemporary applications.

    The windows look fantastic

    "Recently used Dekko Windows to supply the windows and aluminium bi-fold doors for our renovation project. We paid a short visit to their showroom where Rob and Neil were really helpful, showing us around and providing options for us. We were really happy with the whole process and the windows look fantastic. Would definitely recommend this company."
