Sound Blocking Insulation

Do You Want Insulation That Does More Than Just Insulate?

Then You Need Rockwool Flexi Available From Us Greengates Builders Merchants Accrington, Lancashire

How about an insulation which also reduces noise?

The Rockwool SoundPro range reduces ear-deafening noises from machines or the activities of people, and provides ambient situations that allow normal conver­sation.

SoundPro range includes Rockwool products for walls, ceilings, roofs, around machines, and under floors effectively to dampen noise from, or to, the neighbours.

The Rockwool SoundPro range has an open fibrous structure making it ideal for absorbing and regulating noise. Noise should be dampened to such an extent that it no longer interferes with the activity you set out to do. The widespread use of hard reflecting building materials in modern architecture amplifies the problem of noise indoors. For example, Rockwool is used in walls, roofs and floors to dampen the noise from next door neighbours and in enclosures around noisy machines.
