GBG grilles are made of aluminum bars that are sealed in the insulating area between the two glass panes. Cleaning your windows is significantly simpler since both the inside and exterior glass surfaces are unaffected.

A permanent interior and exterior grid with spacer will give the room a genuinely genuine appearance. To match the style of your home, interior grids are also available in wood laminates or Euro-White. External grids are offered in Euro-White or exterior-compatible colors. Of course windows grids are optional if you prefer windows without grids.
