Select Underlay

To achieve the highest and most professional result when installing GrandOak as a oated oor system, we recommend using a quality underlay. GrandOak has a 2mm or 3mm EVA foam underlay, offering a superior higher density fabrication compared to a generic closed cell foam. This ensures thermal and acoustic standards are exceeded for residential and commercial applications.

Perfect for both concrete and timber sub oors, Grand underlay offers peace of mind with up to 200mm extra wide overlapped water resistant 100um PE lm, ensuring your oor is protected for years to come. Refer to our website for our Installation guidelines.
