Construction companies and glazing industry professionals are increasingly discovering the benefits - both in internal and external applications - of one of the oldest forms of glazing - glass blocks. Now firmly on the specification lists as a mainstream building product, glass blocks exhibit excellent strength while offering fire resistance, good acoustic insulation and light transmission Fast becoming a rival to standard construction materials, glass blocks are now also available in pre-cast form for speedier installation. Fire Stop Blocks (F30s) carry internationally recognised fire certification, give two hours integrity and 30 minutes thermal insulation. They also have the added security of being anti-vandal and bullet-resistant while also having excellent light transmission, allowing 80% of natural light to pass through them.
