Balancing Hurricane Impact Resistance and Energy Efficiency

09:59:23 AM on 10/12/2011

With hurricane season wrapping up and cold weather looming around the corner, I thought it would be the perfect opportunity to talk about balancing hurricane impact resistance and thermal performance when trying to weatherproof your building. As we continue to see code requirements for both hurricanes and thermal performance become increasingly stringent, particularly up the East Coast, it can be a challenge to find products that meet the structural and impact capabilities for hurricanes as well as the insulating requirements for the energy efficiency.


But Kawneer can help.


Kawneer has just added two new thermal windows configurations to its hurricane impact resistant portfolio. We now offer the 8400TL IsoLock® Horizontal Sliding Window and our AA®3350 IsoPort™ Single Hung Window. Both configurations are thermally broken and were tested for large and small missile impact. The 8400TL IsoLock® Horizontal Sliding Window, which is a 4” deep pour and debridged thermal window product, achieved a design pressure of +/- 90psf and water performance of 15 psf. The AA®3350 IsoPort™ Single Hung Window is a 3-1/2” deep polyamide thermal window product that has achieved a design pressure of +/- 50 psf and water performance of 15 psf. Both products were tested with multiple installation options making them ideal for new construction or retrofit applications.

These are just a few of the thermal hurricane impact resistant products that Kawneer has to offer, but I hope you’ll visit our hurricane impact resistant webpage for more information.

Stay dry, stay warm and stay safe.
