Felt and rubber flooring underlay provides a versatile solution for soundproofing and comfort beneath your hard floors. These materials offer a combination of properties, with felt absorbing high-frequency noise while rubber contributes to dampening lower frequencies – ideal for reducing impact sounds from footsteps or dropped objects. This type of underlay is particularly well-suited for areas like kitchens, hallways, and bedrooms where noise reduction and enhanced floor comfort are desired. It’s also a popular choice for protecting your existing flooring from damage caused by foot traffic and furniture.
When selecting felt or rubber underlay, consider the thickness you require – thicker options generally provide greater sound insulation but can slightly raise the overall floor height. The density of the material is crucial; denser materials offer superior performance in absorbing vibrations and reducing noise transmission compared to softer alternatives. Ensure the underlay is compatible with your chosen flooring type for optimal adhesion and long-term performance.
Available in various thicknesses and roll lengths, this felt/rubber underlay helps create a quieter, more comfortable living space. It’s often used beneath laminate, vinyl, wood, and even some types of carpet to significantly improve acoustic properties. Check the product specifications carefully for recommended coverage areas to avoid excessive waste when purchasing.

FAQ
What thickness of felt/rubber underlay is best for noise reduction?+
For significant noise reduction, especially in high-traffic areas, a thicker underlay – typically 15mm or greater – made with dense rubber will perform best. Thinner options may offer some sound dampening but won't significantly reduce impact noises.
Can I use felt/rubber underlay under laminate flooring?+
Yes, many felt/rubber underlays are specifically designed for use beneath laminate flooring and provide the necessary cushioning and stability. However, always check the manufacturer’s recommendations to ensure compatibility.
How do I measure the area I need underlay for?+
Measure the length and width of each room you plan to cover in metres, then multiply these figures together to get the total square metre area. Add an extra 10% to account for cuts and wastage during installation.
What is the difference between felt and rubber underlay?+
Felt underlay is generally softer and better at absorbing higher frequency sounds, ideal for reducing footstep noise. Rubber underlay offers superior dampening of lower frequencies, providing greater impact sound protection and often increased durability.
Does thicker underlay raise the floor height?+
Yes, a thicker underlay will increase the overall floor height by approximately 3-5mm per 10mm of thickness. This is worth considering when installing fitted carpets or certain types of flooring.
How do I install felt/rubber underlay?+
Roll out the underlay onto the floor, ensuring it’s smooth and free from wrinkles. Use a roller to compact the material and press it firmly into place for optimal performance. Cut to size using a sharp utility knife for precise fits.
Is felt/rubber underlay suitable for use in bathrooms?+
While some rubber underlays offer moisture resistance, standard felt underlay is not ideal for bathroom environments due to its susceptibility to dampness. Consider a specifically designed, waterproof rubber underlay if using it in a bathroom setting.
What is the typical lifespan of felt/rubber flooring underlay?+
With proper installation and reasonable foot traffic, felt/rubber underlay can typically last for 10-20 years. Regular maintenance and addressing any signs of wear will help prolong its lifespan.
Can I cut felt/rubber underlay to fit around furniture?+
Yes, you can easily cut felt/rubber underlay to fit around furniture using a sharp utility knife or scissors. Measure carefully and make precise cuts for a neat finish; scoring the material first helps prevent fraying.
What is the best way to clean felt/rubber underlay?+
Regular vacuuming with a low-power setting is recommended for cleaning felt/rubber underlay. Avoid using harsh chemicals or excessive moisture, as this can damage the materials and reduce their effectiveness.
