What Is Tyvek House Wrap?

Tyvek House wrap is a house wrap that is commonly used to prevent water from entering inside your house. Tyvek house wrap is made using unique materials that help to keep air and water out whilst allowing water vapor inside walls to escape.

Tyvek House Wrap Problems

1. Not Resistant To UV Radiation

One of the problems of buying Tyvek house wrap is that it is not resistant to UV radiation and as a result it will need constant replacement during summer time. Tyvek house wrap contains synthetic elements which tend to break down or wear out when exposed to sunlight. If you buy Tyvek house wrap and leave it in the sun for more than 120 days without placing it on your house, it will automatically deteriorate in value and will be useless. Therefore, in as much as Tyvek house wrap protects the house from moisture, it doesn’t do well in hot conditions.

2. Lacks Transparency

Another Tyvek house wrap problem is that the material is not transparent when compared to other house wraps. This means once it has been installed, contractors may find it difficult to see the framing of the house. This may result in contractors failing to properly install the wrap or putting nails in the wrong place

3. Not Mold Resistant

Tyvek house wrap has a problem of not being mold resistant, this is mainly because it is not surfactant resistant. Surfactants are contaminants that usually reduce the surface tension of a liquid and lessen the water resistance of a house wrap. Since a Tyvek house wrap is not surfactant resistant it means that mold will build up in the house and it is very expensive to get rid of mold in a house.

4. Prone To Damage

Another Tyvek house wrap problem is that this house wrap is prone to damage especially during and after installation. In most cases Tyvek house wrap tends to tear up during installation and this can be a huge loss to homeowners. After installation the Tyvek house wrap can also easily succumb to wear and tear thus needing replacement. So if you are looking to a durable house wrap you may have to choose another option.

5. Hard To Handle

Tyvek House wrap is very hard to handle, this is because it requires a lot of proper care before being installed. If you leave the Tyvek house wrap for more than 120 days in the sun maybe because of a delay in construction it will start to tear up before you can even install it. Therefore it is important that you buy your Tyvek house wrap once constructions have begun so that it does not get exposed to harsh conditions for a long time.

6. High Vapor Penetration

Tyvek house wrap has a high vapor penetration which can affect the quality of air you breathe in your house. This house wrap has a rating of 56 US Perms whilst the recommended rating is 10 to 20 Perms. Higher Perms means higher vapor intrusion from the outside into your house. Therefore, if you want to prevent this from happening you may be better off purchasing another house wrap.
