If the flooring is expected to be used in a situation with a lot of foot traffic or heavy equipments that will be transported around, then a thicker underlayment will be required to meet the desired acoustic requirements.Īnother thing to consider is the material of the underlay. Thickness depends on the purpose of the floor and its usage. There is no standard thickness for underlayments under vinyl flooring. Common Question #2 – How thick should the vinyl flooring underlayment be? By incorporating acoustic underlay beneath the surface flooring, it adds stability and durability to the tiles, making it less easy to flex. Point loads (highest weight pressure point) of furniture feet may cause the flooring to have curve indentation and a “soft bouncy” feel when walked on, which is a feeling that some may not prefer. When the vinyl flooring is thin, it becomes a lot easier to flex and bend. In short, vinyl flooring itself can be completely self sustainable and does not require an underlayment to function properly.Īnother reason underlayments may be suggested for vinyl flooring is if the vinyl flooring type is thin. If the building requires a specific STC and IIC value range, then underlayments will need to be incorporated into the flooring buildup to improve its acoustic performance and meet those local requirements. As mentioned previously in some of our articles, every building has to follow its own local building requirements, and one of those requirements is the acoustic performance of the ceilings and floors. Short answer is no, vinyl flooring itself does not necessarily need underlayment, however it may need depending on the acoustic requirements of the building.
Common Question #1 – Do vinyl floors need underlayment? They vary in materials and thicknesses, and all acoustically perform differently. It is typically manufactured and supplied in single sheets or rolls which are then laid flat on the floor and installed between the finished floor surface and the base structure below (typically concrete or wood) of a floor ceiling assembly in a building. So let’s get started! Introduction – What is an underlayment?Īn underlayment is simply another layer of product that goes underneath the building’s surface flooring. We’re here to answer the two big common ones today. With how common it is, comes with a lot of questions regarding it. Many buildings especially residential buildings have vinyl flooring.
