SIGA Tapes, Adhesives & Membranes

Benefits of a Well Sealed House

  • Reduction of heating and cooling costs when it comes to air leaks and convective energy loss. Convection is often around 40% of the net loss of energy in a dwelling and can be much more in older buildings.
  • Protection against building damage from water and mold.
  • Higher quality living atmosphere with sound reduction. Large temperature gradients and drafts are perceived as uncomfortable.
  • Protection against vermin

Most people understand the concept of preventing bulk water from entering the home but controlling vapor on the inside is important as well. Water will always find a way in. SIGA’s Majvest WRB home wrap allows water vapor to escape back to the outside, as a very vapor open but waterproof membrane. Pair that with a SIGA Majpell vapor closed membrane on the inside and your walls will be well protected from mold growth and water damage. The Majpell prevents moist interior air from getting into the cold walls and condensing. It also creates a large perm gradient between the outside and inside membranes, encouraging vapor to migrate the exterior and evaporate away.

SIGA's Wigluv tape is extraordinarily versatile when it comes to new construction and renovation projects. It gets more sticky over time and doesn’t embrittle. The Wigluv is quite flexible and can move with the home unlike caulk, foam or backer rod and caulk system. Once a contractor uses SIGA they are always repeat customer. Wigluv is a superior substitute for Zip System tape and sealing tapes that come with windows. These manufacturers make windows and panels, not tapes. Pipe penetrations, raceways soffits and other chases are sealed with ease with it comes to Wigluv, sticking to metal, slick plastic and other vexing substances. It stretches well and is vapor open, allowing components behind it to dry to the outside.
