Tested to Withstand Category 5 Wind Speeds

ICP Category 5 Wind Speeds
August 4, 2020

Time to eliminate mechanical fasteners and minimize tile installation damage, Polyset AH-160 is the only solution you need for tile attachment.

Polyset AH-160 is a two-component, low-pressure polyurethane adhesive that is specifically designed to bond concrete and clay roofing tiles to approved underlayments. It virtually eliminates the need for screws, nails, wire-tie systems, or other fasteners that can puncture the waterproofing membrane or roof deck. Polyset AH-160 also provides added support underneath the tile, enhancing its load-bearing characteristics.

To validate Polyset’s AH-160 superior holding power to mechanical fasteners, a third-party independent lab built two identical roof decks. One of the roofs decks was adhered with Polyset AH-160 and the other was attached with two screws. A high wind-rain simulation test was conducted on both roof decks side-by-side and the performance results were captured on video.

Watch this video to see what happens when the roof decks are subject to rain and high winds in a testing chamber.  They start with Category 1 strength winds of 90 mph. Both decks appear to be holding their own, but when the winds are increased to Category 2, or 110 mph, the deck that was fastened with the two screws begins to chatter. The Polyset AH-160 deck is still securely adhered.

At Category 3 speeds of 120 and 130 mph the tiles of the Polyset AH-160 deck remain in place, but the screw-fastened deck is unable to withstand the higher force winds and the tiles begin to lose their attachment resistance and break-fly off. The test chamber is then set to Category 5 with wind speeds of 160 mph. The Polyset AH-160 roof tiles are bonded strongly on the roof deck and each individual tile is held firmly in place.

Polyset products are available in the form of low pressure one- and two-component polyurethane foam adhesives in pressurized disposable and refillable packaging. All Polyset roofing adhesive products offer speed and simplicity through unique dispensing technology, strong adhesion properties, along with ease in application and durability. For steep slope applications, Polyset roof tile adhesives are approved for use in the most stringent high-wind regions of the world. For low slope applications, Polyset commercial roofing adhesives are specifically designed to adhere insulation boards, cover boards and single ply fleeceback membranes to various substrates.
