There are many reasons a home’s exterior isn’t completed in a given timeframe. Weather or labor delays mean that once a house is wrapped, it can end up sitting and waiting before the final siding is installed.
For most housewraps, including Tyvek, that means there is a risk of the material being broken down by the sun’s UV rays. Tyvek’s HomeWrap has a UV-exposure limitation of 120 days, after which the wrap can become less stable, causing tears. Damaged wrap would then need to be replaced before proceeding with siding installation.
Kingspan’s GreenGuard HPW Building Wrap is UV-stable for up to 6 months, giving builders more time to get the housewrap covered before it degrades. And if you need even more time, some of Kingspan’s wraps, such as the GreenGuard RainArmor and GreenGuard C2000 Building Wraps, are UV-stable for up to 9 months.
For sunny climates or projects that may see a longer span of time between placing wrap and adding siding, Kingspan’s Building Wrap product line is a better option.
