The use of the airtight wrap tapes is slowly getting popular. It is one of the effective media that seals a structure or a building and creates an airtight unit. This ascertains that there is a complete stoppage to the possible leakages.

Why Airtight Wrap Tapes are Needed?

Obviously to build an airtight space!

According to the experts, any slackness in ensuring airtightness reduces the air quality and the energy efficiency of a house or a building.  The R-value of the walls also decreases considerably with the air leakages.

To be precise, the sidings play a crucial role when it comes to ascertaining building's first line of defence against any infiltration. At times, there can be small cracks and gaps alongside the siding from where the air infiltration takes place.

Effective Way of Applying Airtight Wrap Tapes

Undoubtedly, the wraps act as the barrier to the siding and prevent the unwanted air from penetrating the wall cavities. According to the experts, "To ascertain that the airtight wraps tapes do not leak air, it is applied in such a way that it runs continuously over the entire building structure or enclosure.

There are several advantages of these tapes. Firstly, it helps to withstand the various forces that act on the building before and after construction. Secondly, it provides the building with the required durability without compromising on the comfort of the living.

However, do you know that these also leak? Unfortunately, several contributory factors lead to leakages even after precise installation-

  • Improper Use of the Sealant

Manufacturers' prescribed sealant plays a major role in ensuring airtightness. If the sealing is not done properly, the chances of leakages are high. According to the professionals, sealing the gaps with the manufacturers' tape improves the performance considerably by 25% approximately. Therefore, post installation of the house wraps, sealing the seams is crucial to make a building airtight.

  • Irregularities in the Repairing Leakages

Most instances of leakages have been reported because of the irregularities in the repairing of the cuts or tears. In fact, a so-called energy efficient home loses its efficiency if the sealant is not used correctly. Specifications of the tapes should be kept in mind before applying. For example- house wrap tapes of 6-inches should be used to repair the larger tears.

  • Ignoring some of the Dead Zones of the House

There are times when a person thinks that all the corners of the house have been properly sealed. However, some dead zones get skipped, especially the bottom edges. It is, therefore, recommended to thoroughly check all the nooks and corners of the house to ensure there are no leakages.

  • Improper and Abrupt Sealing

No matter how well you use the airtight wrap tapes, there is a possibility of loopholes because of the rough edges of the windows and doors, or gaps caused during the installation of the various utilities. So, proper care needs to be taken care when it comes to thoroughly sealing such leakages.


Lastly, it can be said that an effective wrapping of the gaps does not always ensure a space that is airtight. Regular inspection and maintenance need to be carried out to keep the house airtight and make it an energy efficient one.
