Snow Guard Tests

The Truth About Test Results


 

Professional Testing: At MetalRoofSnowGuards.com we take pride in our product test results. Each model has been tested by Architectural Testing, Inc., the most respected name in building envelope testing. Our conclusive test results speak for themselves and are the most reputable in the industry. Click each image for a larger picture.

"At IceBlox, Inc. we have applied over 30 years of snow retention experience to developing quality snow-guards that have passed the test of time. Part of the reason our snow guards are so dependable is because they are designed to work and last a lifetime. We will continue to innovate and test all new products to be certain they retain the same quality as our Snojax, SnoBlox and Icejax products." -Brion McMullen, President / CEO

The Test Apparatus
The tests performed on each model of snow guard simulate actual and realistic snow loads and weight conditions. We tested each guard by applying pressure via the steel rod, simulating weight, while measuring the force of the load against its face. Our tests simulate actual snow load shear conditions unlike other competitors snow guard testing that pulls upward on the face of the guard, a force that is never found on a snowy, icy roof. We also found it necessary to only perform static laboratory testing since our 21 year unbeaten track record of the SB-190 clearly speaks for itself!
Flush Mount
The test presses on the face of the guard where the snow load is greatest, simulating real snow load conditions. Please note that all our guards have a forward mounted flat face designed to form a strong holding field across the entire roof to retain the snow & ice until it can safely melt away.
 

IceJax I
We tested both methods of attachment, adhesive mount with SureBond SB-190 and mechanical mount with # 14 SS screws & silicone. We have also tested additional alternative tapes, adhesives and sealants but have not been pleased with the results or longevity of any other variety of snow guard adhesion. The SureBond SB-190 repeatedly provided optimal holding power and is time proven since we first pioneered its use for our polycarbonate Snojax II snow guards in 1985.
Impressive Results
We were impressed to find that when we were done testing, each guard was still intact and the release was directly attributed to screw failure or release of the mounting method, not because of a structural failure by the guard. This image was taken after this guard had just held 6388 Lbs, notice how its only disfigurement is where the screws broke and dug into the guard.
