The technology of tomorrow - V-Perfect
We are thinking about the functionality, but also about the aesthetics of our products, which is why in the production of the PRIMO window we use the most modern technologies currently available on the market, based on the assumptions of Industry 4.0. Such a solution is the V-Perfect flashless welding technology, which we use as standard in the PVC PRIMO windows.
It allows the corners of PVC windows to be joined almost imperceptibly during the welding process. The result is a perfect jointing effect, unattainable with any other technology.

WIŚNIOWSKI brand PRIMO windows are guaranteed for up to 7 years. We are sure that this is just blowing the whistle, but we also want you to know that you can count on us.
PRIMO windows by WIŚNIOWSKI are designed and manufactured using VEKA window profiles, which are classified as class A according to PN-EN 12608.
We guarantee an elegant and modern design for our windows, which you can personalise with the Home Inclusive 2.0 collection.
