Acoustic and Intumescent Sealant is an absolute essential for soundproofing. General advice for the majority of soundproofing products, especially with the use of Acoustic Plasterboard, or installing rigid materials, is to leave a 2-5mm gap from the perimeter to reduce 'Flanking Transmission', a negative impact of sound taking an alternative route to the direct and 'obvious' path, for instance through the wall and not the two adjacent walls. This form of 'Flanking Transmission' is where the two solid materials in contact quickly pass through vibration, and the Acoustic Sealant acts almost like a putty, it does not set solid. Acoustic Sealant is also to be used between Acoustic Plasterboard layers, and on each sheet, to increase the air-tightness of the 'acoustic barrier'.

We are always looking for the best ways to describe to you the world of soundproofing through introducing guides that range from the basic principles of sound, how to best soundproof surfaces and what to look for, and how to understand acoustic test data, to name a few! We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!
A combination of the following will always result in a much improved acoustic performance.
Whether you're soundproofing an already existing home against neighbour noise, specifying materials for a clients 'future-proofing' or adhering to acoustic regulations, it is important to select the correct system, with the right methods applied. Something often neglected is the contact of materials with one another, and incorrect installation of materials. A common error is assuming that a ceiling soundproofing system, the use of Acoustic Plasterboard, for example, should be fitted tightly against the adjacent walls to minimise the gaps. This is incorrect, and this is because this will not only allow vibration to transfer into the walls but will limit its suspension, meaning that its performance for impact will be lessened.
Acoustic Sealant is essential to soundproofing walls, floors and ceilings. Whenever we are recommending the use of it, it is because there needs to be a 2-5mm expansion gap from the adjacent surfaces, and this where you apply Acoustic Sealant.
Get the best from your soundproofing system by using Acoustic Sealant in the correct places. With any concerns or questions on how to install a specific system, talk to us about your project on 01937 588 226.
This product is part of the following systems:
With large projects and the number of gaps that often require sealing, a 300ml requires a very frequent changeover which can cost time. With the use of an Acoustic and Intumescent, it helps with smoke prevention in the case of a fire by expanding with the heat and remains viscous and flexible under the correct temperature range as hardening will cause vibration to transfer into the adjacent surfaces.
At first, you will want to cut the nozzle to a pea size opening for an approximate 5mm bead application and puncture the tin lid on the inside with a screwdriver or other device long enough, forgetting to do so could cause the adhesive to come from the other end when pressure is applied to the applicator gun.
When dried the sealant will remain a white colour, the sealant can be sanded down and painted over during decoration.
