Parallel Sliding doors PSK-Portal

Wooden doors PSK-Portal - the principle of operation of the PSK-portal is very similar to the principle of operation of a bus door - when you turn the handle, the sash moves inside the room and moves to the side, opening the passage. Perhaps this is not the most compact version of a glass door, but it is definitely one of the most affordable. The glass unit, profile and frame for PSK-portals are the same as in the production of wooden windows. This ensures both high thermal insulation performance of the PSK system and affordable prices.
