Metaglas® Discs The Optics of Glass The Strength of Steel
Metaglas® safety glass with Factory Mutual Approval(FM)Mechanically prestressed Metaglas® windows constructed of borosilicate glass fused with a dimensionally adapted metal frame-ring, constitute an alternative to conventionally annealed or thermally prestressed (tempered) glass discs.

A principal advantage lies in the fact that the possibility of a sudden, unexpected rupture is totally excluded, and any crack that might develop, at worst, may slightly affect visibility.

In addition to the unsurpassed pressure and impact resistance, the metal frame provides rigidity to prevent breakage in the event of uneven bolt tightening during installation.
