What are the dimensions of the DuoLift Acoustic Separation Pads? We supply a pack of 10 DuoLift acoustic separation pads, each measuring 250mm (W) x 250mm (L) x 3mm (D). They are made from agglomerated cork and recycled rubber, which easily absorbs sound and impact between the joists or your subframe. How many DuoLift Acoustic Pads do I need? This is dependent on the size of your decking or cladding structure. Due to their protective properties, you can never use too many. Ensure you have an even covering of pads across your subframe, which should be sufficient to absorb any sound or impact between the joists. What is DuoLift? DuoLift is an innovative product developed by Millboard. Its intention is to support and overcome the challenges of installing decking on hard surfaces. It provides options for various heights and helps fit decking around differing landscapes and levels. With a clever system of joists, frames, and support components, DuoLift can raise your decking to a maximum height of 350mm.
