Wooden Flooring: Installing Builders' Film for Optimal Protection

Posted on: 13 December 2016

Builders' film is an important material in the construction industry, and it can be used for numerous types of applications. In general, the sheet is made using polyethylene, a strong plastic material. The most beneficial property of the film is its low level of biodegradability. This aspect means that the plastic is impermeable to water and will not be changed due to prolonged exposure to moisture. One of the important uses of PE builders' film is as a vapour barrier for wooden floors. Basically, the layer will prevent the penetration of moisture from the ground and into your floor planks. If you decide to perform this as a DIY project, consider using these guidelines for the best performance of the film.

Choose the Right Film

The polyethylene builders' film products in the market are not homogeneous in quality or performance. Therefore, it is important to be keen when selecting the perfect one for your home. The most important factor is the thickness of the film. Naturally, heavy-duty or high impact products will provide the maximum advantage with regard to moisture protection for your floors. However, the cost can be a limiting factor, particularly when covering a large area. Often, good quality medium impact films will provide a relatively decent vapour barrier.

Install the Sheet Properly

When you place the builders' film beneath your flooring, you should ensure that the layer is smooth and fairly taut. If the sheet is loose and full of creases, the extra plastic will keep shifting as you install the flooring. Consequently, the builders' film will be more likely to sustain tears and rips. This will compromise the moisture protection provided by the sheet. In addition, you should place the polyethylene sheet beneath the subfloor as opposed to above it. Basically, the subfloor is also vulnerable to moisture damage. It will degrade after prolonged exposure to dampness, and mould might even grow in this flooring level. The right placement will ensure the prolonged performance of the entire floor.

Secure without Damage

Finally, you should secure the builders' film without causing any tears or perforations. In simple terms, you cannot drive nails or screws through this plastic layer. Otherwise, the moisture from the ground will be able to penetrate into your floor. There are different installation options provided by suppliers of construction materials. One of the simple solutions is to use non-penetrative clips to hold the edges of the film before installing your wooden floor.
