The Island Style Roof passed FL's rigorous TAS-125 and TAS-100 testing with zero water infiltration, even under sustained winds of 110 MPH. Its FL Product Approval, including HVHZ certification, confirms hurricane-ready performance.
In uplift testing, the Island Style Roof withstood pressures equal to 342 MPH winds until the test rig’s framing failed—while the roof itself remained intact. Certified under TAS-125, it’s engineered to resist storms far beyond Category 5 strength.
The Island Style Roof earned a Class A Fire Rating after rigorous ASTM E108 testing at Intertek, outperforming standards with flame spread limited to just one foot. These results confirm its exceptional fire resistance and long-term durability.
Wind Driven Rain
For nearly a decade, the Island Style Roof has protected Caribbean buildings with proven durability against hurricanes and tropical storms. To demonstrate its performance for wider markets, Acrylabs subjected the system to the most rigorous testing protocols available.
After repeated storm damage, Florida raised building standards and became a leader in roofing approvals for hurricane zones. State law requires roofing systems to earn statewide or local approval, showing resistance to structural wind loads defined by the Florida Building Code, before permits are issued. The Acrylabs Island Style Roof met these strict requirements, achieving Florida Product Approval for use statewide, including in the High Velocity Hurricane Zone (HVHZ).
At PRI Construction Materials Technologies, an accredited Tampa facility, sample roof sections were built and tested under controlled hurricane conditions per TAS-125 and TAS-100.
Because roof valleys are vulnerable to wind-driven rain, a sample with a valley detail was tested under increasing sustained wind speeds while large volumes of water were introduced. (Wind speeds were posted in the observation window.)
The Island Style Roof showed zero damage and no water infiltration, even as test equipment reached its maximum of 110 MPH.
Wind Uplift
The Proof We Can Stand Up To Hurricanes
Powerful equipment was used to depressurize the roof sample surfaces, increasing pressure from beneath.
Testing was halted at 300 psf when the 2”x10” structural framing of the sample roof section began to tear apart. Even under these extreme pressures, the Island Style Roof system itself showed no signs of damage.
The uplift test pressures equate to wind speeds of 342 MPH, though Florida’s TAS-125 standard reduces this rating to 240 MPH to provide a substantial safety margin. For comparison, a Category 5 hurricane has sustained winds above 155 MPH. The Island Style Roof is engineered to withstand storms producing winds far beyond Category 5 strength.

Fire Testing
To verify durability and fire resistance, the Island Style Roof was subjected to severe fire testing with dramatic results. Sample roof sections were built at Intertek Building Products & Building Sciences in Pennsylvania and tested in strict accordance with ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings.
Both the burning brands test and the spread of flame test were performed, with outstanding outcomes. For a roof to achieve a Class A Fire Rating, the spread of flame test permits flames to climb a maximum of 6 feet up the roof slope. The Island Style Roof limited flame spread to just 1 foot, demonstrating exceptional fire resistance.
Based on these results, the Island Style Roof earned official approval with a Class A Fire Rating.
