AngelStep® 250

complementary acoustic underlay

AngelStep 250 makes it easy to achieve the highest acoustic rating of 6 stars. As a high performance acoustic underlay, it can be used on its own or in harmony with the AngelStep range to increase acoustic performance. To find out how this can be achieved, please contact Acoustica for technical support.

Add AngelStep® 250 to other AngelStep® acoustic underlays for a bespoke solution to airborne and impact noise. Ideal for layering, AngelStep® 250 is just 4mm thick with an open weave polyester construction that can fine-tune the end acoustic result.

Easy to install, AngelStep® 250 is suitable for underfloor heating systems and is moisture and rot resistant. Like all AngelStep® flooring, it’s unaffected by weight and won’t degrade, offering durable performance for the life of the flooring.
