Laminated Glass

Unprotected Home

During extreme weather events windborne debris travels at high enough velocities to shatter glass. A broken window or door will allow storm winds into the home, if these winds don’t find an exit, they’ll make one.

Protected Home

Though impact glass may shatter, the lamination layer prevents the barrier from being compromised, meaning the strong storm winds are prevented from entering the home.

An impact sealed unit employs one or two standard panes of glass alongside one laminated pane. The laminated pane actually comprises two panes that are laminated together. Though the glass may shatter, the laminated interlayer remains intact.

Impact Glazing

Keeping hurricane winds out of your home.

A compromised building envelope during an extreme weather event can cause catastrophic damage to a home, as strong winds can now enter the structure with no way out. Loewen’s impact glazing prevents windborne debris from penetrating the home. Even when broken, the glass fragments remain integral, adhering to the plastic interlayer, to preserve the building envelope.

All Loewen StormForce products use industry leading laminated glass. Laminated glass has the look of ordinary glass but offers a fortification against accidental impact, forced entry, sun damage and noise that far surpasses that of standard glass.

With impact products rated up to DP 85, Loewen’s superior design is able to withstand 9,000 cycles of positive and negative wind loading, 105 psf structural loading and the impact of a D-Missile*.

* D-Missile certified products are tested to withstand impact from a 9 pound 2 x 4 stud, 8 feet in length, at an impact speed of 50 feet/second. Products are then tested to withstand 9,000 positive and negative wind loading cycles without failure of the building envelope.
