Loewen's StormForce Series comprises our impact-rated windows and doors. We implement laminated impact glass, and in some cases additional bracing, to meet impact certifications. Besides that, these are the same architecturally correct and high performing windows and doors we're known for.
Born out of an unfortunate necessity, our StormForce Series has been put to the test multiple times in coastal regions like the South Eastern US and Caribbean.
Our structurally enhanced StormForce products are tested and certified by independent agencies. These third-parties test our products based on extreme conditions and varying product sizes. There are several different certifications throughout our product offering including Wind Zone 4 and Wind Zone 3, which are ASTM standards, and High-Velocity Hurricane Zone (HVHZ), which certifies products meet code compliance in the Miami-Dade and Broward counties in Florida.

Features
Impact-product testing and certification is a very esoteric field. There are different kinds of testing overseen by different organizations which produces different kinds of certifications; all of which influences whether or not a product will meet your local building codes. It’s crucial that you consult your local experts when selecting impact-rated products; your local experts will best understand the nuances of your local codes.
Besides the obvious protection against extreme weather conditions, impact products are often implemented for security reasons. It's next to impossible to smash through laminated impact-glass.
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.
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.
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.
