Not all flashing tapes offer the same level of performance when it comes to UV resistance. The key metric of performance in terms of UV protection is how long the tape can withstand exposure without compromising durability, adhesion and weather resistance. This is important since complications on the job site like weather delays, contractor scheduling or supply chain issues can often cause flashing tape to be exposed to the elements for longer periods of time.

Some flashing tape options will start to degrade after just a few weeks of UV exposure. The sunlight starts to break down the outer layers of the tape causing it to become brittle and compromise the overall integrity of the building envelope.  And UV rays aren’t the only elements working against flashing tapes. Pros who work in cold weather conditions (below 50F) should confirm their flashing tape has a lower application temperature.  Some tapes are unable to adhere in colder weather, even with the aid of spray adhesives, leading to door and window installation delays. One product, OSI QUAD Butyl Flash, resists UV exposure for up to 180 days and can be installed in temperatures as low as 25F.

Flashing a window or door during the install typically requires three products: flashing tape, sealant and insulation foam.  However, very few brands offer a complete system.  These products will come in to contact with each other during an install and it is important to ensure they adhere well to one another without causing any physical degradation due to poor chemical compatibility. Purchasing and using three products from multiple brands increases the risk of problems.  The easiest way to confirm compatibility is to ask the manufacturer.  And incompatibility does not always present itself in the short term.  It can happen long after the install and flashing system has been covered by trim and cladding.

The QUAD Window and Door System is designed to outlast the elements and gives pros everything they need for reliable installations. Every product is compatible with each other and OSI provides expert training to support residential and light commercial installations. Pros get access to best practices through the OSI certification program and can talk with technical service experts for protocol development. The QUAD Window and Door System includes high-performance products like QUAD Butyl Flash.
