The Features of FAKRO’s Laminated Glass

FAKRO offers laminated glass on all its skylights and roof windows. FAKRO uses a number of different configurations of glazing based on the requirements of the skylight or roof window, this includes double, triple and now Canada’s first quadruple glass unit. Laminated glass has many benefits.
Sound reduction airplane
Superior Sound Reduction

Reduces the effects of sound by up to 30% compared to standard double pane glass, and up to 50% less than a acrylic skylight. Bring natural light in without additional noise such as traffic or planes.

Hammer resistant security glass
Additional Security

Laminated glass is more difficult to break and penetrate. So, if you are concerned about security it is worth considering. The vinyl interlayer holds the glass together in case of breakage.

Uv protected glass
Best in class UV Protection

Laminated glass lets the light in but protects your home from UV rays. The ideal choice to prevent fading of your floors, furniture and artwork.

Increased Safety
Increased Safety

Laminated glass provides additional safety. Even when broken it does not shatter because the two inner layers of glass are bonded to a thin plastic membrane.

Many building codes require laminated glass for out of reach applications.
