When it comes to roofing, many professionals opt for a synthetic subfloor to improve water resistance and protection against the elements. These products are usually made of long-lasting polymers, which provide greater strength and longevity. There are several types of synthetic subfloors available, such as laminate floors with built-in polyethylene foam backing, luxury vinyl plank (LVP) with a rubber subfloor, and floors designed with cork already incorporated. When it comes to acoustic counterweights for tiles, rubber is often used.
However, this material has one of the highest gas emissions in a home, so it is best to avoid it. A non-stick mat is mainly made of foam and a little asphalt adhesive, making it an improvement over most rubber layers. Healthy options include natural wool felt for wool carpets, polyethylene, ethylene vinyl acetate (EVA) foam, low-odor synthetic rubber, and built-in synthetic felt. Recycled rubber should be avoided. In some cases, an additional subfloor is not necessary.
For instance, if the subfloor is already attached to the underside of the floor covering, then an extra layer of subfloor would not be beneficial. Laminate flooring manufacturers often indicate that a loose subfloor with a pre-fixed subfloor should not be used. The type of roofing material will also determine which type of synthetic subfloor is best suited for the job. Metal roofs work well with a synthetic subfloor that has greater heat resistance since metal can retain more heat.
On the other hand, traditional asphalt tile roofs are better off with a felt roofing subfloor. Synthetic subfloor (without bitumen) is the preferred choice among roofing professionals today. It is important to check the warranty before installing any type of synthetic subfloor since many have a pre-incorporated sublayer and the warranty can be canceled by adding another subfloor.
