MAX PROTECT
We know that making a hole in a roof is something that has to be 100% secured. Severe weather can affect the structural integrity of the house and by choosing the right window you can help reduce the risk of major damage.
MASTERWOOD
We guarantee that all our wood is certified, rigorously selected, Arctic Nordic Pine, which is known for excellent density and increased durability due to very harsh weather conditions of the region.
COMFORT AND SAFETY
Comfort Glass keeps the house warm in the winter and prevents heat build-up in the summer. Additionally, thanks to blocking 95% of UV rays, it protects furniture and carpets from fading. That's all thanks to the double-pane window glazing unit filled with krypton and covered by two low-emission, double action layers of coating.
MAINTENANCE
Our maintenance process starts in the making. See how our PVC frame windows construction looks like step by step..
NEXT 20 GUARANTEE
20 years homeowner to homeowner transferable guarantee. Add value to your home when you resell or rent it on top of the peace of mind you get.
NOISE BLOCK
Enjoy the silence! The Noise Block technology reduces external noise 50% more effectively than comparable windows on the market. It consists of a 6mm thick, toughened outer pane, an advanced flashing system and an inner pane with 2 layers of noise-reducing film.
TESTED TO PERFECTION
We hit our Ultima roof window with a 50 kg impactor. It might sound extreme, but then so might be the weather. The result? Nothing happened. Proof that our windows resist even the most extreme weather conditions.
