Tyvek has long been the Kleenex brand for house wrap and it has become a critical component to your exterior wall performance. Until the last few years, house wrap was not required in residential building codes and most of the homes we work on that were built in the 90’s and earlier have no house wrap or weather barrier installed, which can cause a lot of mold and rotting to the wall sheathing and framing. The concept behind a good house wrap or weather barrier is that it allows the moisture to escape your home but does not allow it to enter. We install a high performance weather barrier (house wrap) on EVERY project to ensure your home is protected and performs like it should.
