LWS&I Windows and Doors

uPVC SLIDING SYSTEMS



uPVC sliding systems offer better arrangement possibilities by saving space and providing the outstanding option of seamlessly connecting rooms. They can be used to connect a living room with the garden or a flat with a terrace so that the space is unobstructed by protruding thresholds. These systems are so easy to use, especially in HST options, that anyone can use them, and their performance is good enough to complement passive buildings.

This is the ideal solution for all investors intending to replace walls with glass and eliminate unnecessary barriers. The use of specialized glazing and additional joinery, such as blinds and shutters, offers the possibility to conveniently control the amount of light and heat that enters the room. All such products are available from LWS&I.
