PVCUw valueHigh definition finishing


A folding door system opens up rooms in a particularly elegant and efficient way. The beauty of a multi-fold door is that the multiple panels fold up to create an opening that can be as large as the size of the door frame. All doors are folded in a space-saving manner and conveniently slide to the side. In this manner, every room can be opened out fully, making use of the whole width. Both opening directions available: inside or outside opening.
Thanks to the optimized bogie technology and pin-guided rollers, the Fold & Slide hardware convinces by means of its perfectly smooth operation.
Doors can be designed in various combinations, sizes, decorative partitions and all other individual features of the product may vary to fit your home design needs.

Insulated glass units

Insulated glass units play significant role achieving pleasant, comfortable indoors environment, high thermal properties and preventing heat loss. Our standard 2 -layers or high-performance 3-layers insulated glass units are produced with energy-saving low-emissivity (Low-E) selective coating and filled with argon gas. Warm edge spacer bars between glass layers significantly reduce conductivity (compared to alu) and uplift the overall U-value of a window. Depending on the purpose, insulated glass units can have additional characteristics: safety & security, solar or sound control and etc.

Below, our special glasses range. Contact us for more information.

Safety & security glass units

Safe and secure insulated glass units can be tempered, laminated or combine both characteristics in one. It provides protection against the risk of injuries due to accidental breakage and serves for protection of property from vandalism to burglary. Several options are available depending on required level of safety/security.

Solar control glass units

Solar control glass units reflect and filter the sun’s rays, protect all the interior surfaces from fading at same time allowing natural daylight into the room without uncomfortable visual glare. If you are worried about overheating where the glass is under direct or frequent sun exposure, then the insulated solar control glass units is your choice.

Sound control glass units

In order to avoid annoying traffic noise we recommend to choose insulated sound control glass units with increased noise reduction level. We offer a broad range of special glasses depending on desired acoustic level.

Glass controls noise by:

  • Reflecting the noise back towards the source,
  • Absorbing the noise within the glass.

Self-cleaning glass units

Self-cleaning glass with special coating is the ideal solution for higher floor buildings with limited cleaning access. The glass uses the natural daylight and the rainwater to break down organic dirt. It also dries quicker and tends not to leave as many streaks, or traces of water. As long as you have daylight and rain, it’s nearly maintenance free.

Anti-fog glass units

The occurrence of external condensation can be a problem, especially in spring and autumn on high thermal insulated windows or doors. Anti-fog glass units significantly reduce the amount of external condensation and make your living space more comfortable while ensuring a clear view through the window.

Decorative glass units

Decorative glass units with timeless textured patterns enhance style and design for your windows and doors. It
is an elegant way to create privacy to certain areas.
