Moisture can cause severe damage to a home when exposed for a long time. Hence one easy way to deal with it is building wrap, generally known by many names such as house wrap, building wrap, or WRB.
Its purpose is to protect the building from bulk water from excessive rain, wind-driven moisture, and water vapour. Applying the sound barrier in the correct place with assistance from experts and professionals such as western Sydney builders can be significant.
This will help protect the building designs, perform better against weather deterioration and also enhance the overall aesthetics of the building. This barrier has three primary defence mechanisms: drainage ability for rain penetration, water holdout for bulk water, and proper permeance or breathability for water vapour.
So let’s have a closer look at why one needs building wraps to fight the effect of weather over the years.
Effective Benefits Of Applying Wraps To Your House!
- Bulk Water Holdout: Bulk water holdout can be the most basic function of a WRB, which is basically holding out as much water off the building. A high-performance house wrap ought to pass a couple of tests to measure its resistance.
First comes the water ponding tests, which measure the wrap’s resistance against a pond of 1-inch water for approximately two hours. Next comes a more stringent hydrostatic pressure test in which the material is subjected to a high-pressure water column for a time period of five minutes.
- Drainability: One of the most significant functions of a wrap is to remove trapped water from the wall assembly. Most professionals like western Sydney builders test the drainage ability of the house wraps in accordance with the ASTM E2273 measure.
Given the wide variety of drainage building wraps available in the market, the water’s rate can vary significantly. As technology advanced, the use of integrated drainage systems in such wraps also increased. This is done by creping, weaving, embossing, or using filament spacers.
- Permeance: Be it any kind of wrap, it needs to breathe in order to prevent moisture buildup in the wall cavity. The permeability of the building wrap measures the amount of water vapour transmission the wrap will permit over a period of time.
As its most basic function, a WRB must hold out liquid water
Conclusion
Having a building wrap is a very efficient way to retain your building’s structural performance and looks over the years. However, as you have seen, the effect of water, which may be in bulk or even vapour, can be very detrimental to your building. This is why you should get your building protected with a WRB from a professional from the Executive Building Group today!
