FAQ
What type of flooring is this underlay suitable for?+
This 1m x 5m underlay is designed primarily for use with laminate and vinyl flooring. It’s also compatible with engineered wood, though you may want to check the manufacturer's recommendations for specific thicknesses.
How thick should I cut this roll to achieve the correct thickness?+
The recommended thickness will depend on your flooring type and desired level of noise reduction. Generally, 12mm – 15mm is suitable for laminate and vinyl, while engineered wood may benefit from a slightly thicker layer.
Does this underlay provide adequate sound insulation?+
Yes, the foam construction offers good sound insulation properties, reducing impact noise transmission between floors. However, results can vary depending on wall construction and other factors – consider additional acoustic measures for particularly noisy environments.
What is the roll width of this 1m x 5m underlay?+
The roll width is 1 metre (approximately 39 inches). This allows you to easily cut the underlay to your required length, minimising waste and ensuring a perfect fit for your flooring project.
How easy is it to cut this underlay?+
This foam underlay is relatively easy to cut using a utility knife or scissors. A straight edge can be used for accurate cuts, particularly when working with longer lengths.
Does the colour of this underlay match standard flooring colours?+
The underlay is typically white, but variations may occur. It’s advisable to check the colour against your chosen flooring before installation to avoid noticeable differences.
What is the approximate weight of one roll?+
The weight will vary slightly depending on the density of the foam, but a typical 1m x 5m roll weighs approximately 8-12kg. Please check the product specifications for precise details.
Can I use this underlay in a damp environment?+
While suitable for most flooring types, avoid prolonged exposure to damp environments. Consider using a moisture barrier membrane beneath the underlay if installing over concrete or other potentially damp subfloors.
How does this underlay compare to thicker underlays?+
This 1m x 5m roll offers a good balance of performance and cost-effectiveness. Thicker underlays provide greater noise reduction but can increase the overall floor height and may not be necessary for all applications.
