UNDERLAY

G2 EVA & G3 EVA Underlay

To ensure the highest and most professional result when installing GrandOak as a floated floor system, it is important that what is laid underneath your GrandOak floor is designed to last the test of time. Grand Underlay has a 2mm or 3mm EVA foam underlay, offering a higher density fabrication compared to standard closed cell foam. Ensuring thermal and acoustic standards are exceeded for residential and commercial applications.

Perfect for both concrete and timber subfloors, Grand underlay offers peace of mind with up to 200mm extra wide overlapped water resistant 100um PE film, ensuring your floor is protected for years to come.

Ask your local retailer for Acoustic ratings.
