SlimLine 38’s sleek, user-friendly design makes it a highly insulated system, ideal for both contemporary and classic architectural projects. These narrow-profile aluminium windows and doors offer unlimited design freedom, thanks to their many minimalist variations.

Available in three versions:General information:
  • Classic aluminium window – with smooth, slanted surfaces familiar from wooden windows, it fits well into any classic construction project.
  • Cubic aluminium window – its slim, angular design is best suited to contemporary architectural projects. This type is the insulated counterpart to our Modulusz interior system, and its design is focused on a slim and slender appearance.
  • Ferro aluminium window – slim, with stepped extensions, recommended for projects where steel windows and doors are planned, but higher quality insulation and a more favourable price are desired. This product has been developed to imitate the slim appearance of steel windows and create pleasant shadow gaps on the facade with straight lines.
  • thermal insulation of the frame – Uf 1.9 W/m²K
  • thermal insulation of the entire door – Uw 0.99 W/m²K
  • hidden straps and hinges
  • hidden drainage
  • even with a safety barrier
  • with integrated mosquito net

This system is from Reynaers, not an XS-ALU development. We supply it for projects that need it alongside our own systems.

MasterPatio is a versatile lifting and sliding door solution.

MasterPatio is the most versatile lift-slide system to offer, the ideal combination of a clean look and high insulation performance. Although this sliding door system is not the narrowest, its appearance remains clean with fully concealed hardware and optional concealed motorisation, which can move sliding panels weighing up to 500 kg at the touch of a button.

In addition, sliding doors are not only easy to operate but also offer certified security with PAS 24 and RC2 compliant burglar resistance. The +High Insulation+ design even provides passive house-level thermal insulation.

General information:

  • It has a clean design, even providing a fully concealed wall connection, with a low, barrier-free threshold that remains almost unnoticeable.
  • The pocket design is ideal if you want to hide the door in the wall. In this case, the entire sash slides discreetly into the wall, providing an unobstructed view.
  • Ventilation function and integrated roller blinds with mosquito nets further enhance indoor comfort.
  • thermal insulation of the frame – Uf 1.9 W/m²K

Radikal is our newest minimalist sliding exterior door system. Invisible elegance, as the frame almost disappears, leaving only the view. The 38 mm visible ultra narrow aluminium frame provides maximum visibility while supporting glass sashes up to 1000 kg. The minimalist frame highlights the harmonious interplay of natural colours, making it the perfect addition to a modern home.

The system is characterized by extreme durability, as we used premium marine aluminium alloy with stainless steel reinforcements that can withstand industrial loads. The size is limited only by the triple-layer toughened safety glass, allowing it to meet the needs of virtually any space.

The front door, which not only locks, but opens up space.

Let’s dare to dream big! It is possible to create a monumental door up to 6 metres in length, up to 500 kg, which is beyond anything we have ever imagined. This is not just a door. It’s the face of the house, a work of art of undisputed prestige and taste that will be talked about for a long time to come.

Radikal is where power meets precision, because behind the striking beauty of every Radikal door lies a major innovation: our proprietary 3D adjustable hinge system and magnetic rubber seals. This technology ensures that even doors weighing up to 500 kg operate effortlessly, quietly and elegantly – even when fixed at different angles.

Choose the finish that suits your taste from anodised aluminium, natural stone, glossy or coloured glass, special ceramics, timeless stainless steel or warm wood veneer combined with copper.

The result? A completely unique, unparalleled entrance door.

All our products are made from 50% recycled aluminium, making our doors and windows an environmentally conscious choice.
