Installing an internal wrap for Air Tightness and Vapor Control

Efficiency Matrix demonstrates some key techniques and ideas for installing an internal fabric vapour retarding material called Smartvap(Proctor) inside a residential wall system in a temperate climate of Melbourne Australia.

Proctor Smartvap internal vapour retarder, can provide several significant benefits to your home:

1. Controls Moisture Levels: In cold or temperate climates throughout the world where there is a significant difference between indoor and outdoor temperatures, vapour barriers help prevent water vapour migration. It can help control moisture levels in the house, thereby keeping the indoor air quality healthier and preventing moisture damage to the structures of your home.

2. Combined with a heat recovery ventilation system, a vapour barrier can significantly improve indoor air quality and improve the efficiency and effectiveness of the heat recovery system itself.

3. Prevents Damage: By controlling moisture levels, a vapour retarding wrap can significantly reduce the risk of damage caused by dampness, such as mould, mildew growth, or decay in the home. This prevention can extend the lifespan of your building materials and reduce maintenance especially in extreme climates.

4. Energy Efficiency: It can enhance the effectiveness of insulation, providing you with improved energy efficiency. Keeping the insulation dry preserves its R-value (thermal resistance), thus helping save on energy costs.

5. Comfort: A well-placed vapour barrier can also improve the comfort of your home by helping to maintain consistent humidity levels.

It's important to note that the need for a vapour barrier, and where the vapour barrier exists in a wall or roof system can vary based on a region's climate, the type of construction, and local building codes. Improper placement can sometimes lead to trapping moisture in unintended places, so it's best to consult with a building performance consultant when you are considering building a home or retrofitting a product like this onto an existing home.
