Due to their thickness, our acoustic mats are very heavy.  Their weight allows the tiles to be fitted without adhesive (loose laid) as each tile butts together and stays put.  These heavy mats can be handled by a fairly strong individual but we would advise getting another person to help with installation due to the lifting and laying down.  Feel free to get in touch if we can help further with any queries regarding our Soundproofing Acoustics range.
