Retrofit Soundproofing: Cellulose Injection Service
Soundproofing for Walls, Floors & Ceilings
If you want to stop noise without the disruption of a full renovation, our Celbar Injection Service is the answer. Using our specialised Cyclone Pumping System, we can soundproof your existing structure with minimal impact on your home’s finish.
Based in Borehamwood, we are one of the few specialists in London and the Home Counties offering this "drill and fill" acoustic solution.
How the Cyclone Injection Process Works
Traditional soundproofing often requires removing plasterboard, which is messy and expensive. Our pneumatic system allows for a "surgical" approach:
-
Precision Access: We make small, strategic holes (approx. 50mm) in the existing wall, ceiling, or floor.
-
The Cyclone Pump: Our high-powered Cyclone machine pumps loose-fill Celbar cellulose insulation into the cavity at high pressure.
-
Dense Packing: The machine ensures the insulation is packed to a specific density, filling every nook, cranny, and gap around pipes and wires that standard slabs simply can't reach.
-
Seamless Finish: Once the cavity is full, we seal the holes, leaving the surface ready for a quick flick of plaster and paint.
Why Choose Injected Cellulose?
-
100% Fireproof & Safe: Despite being made from recycled paper, the insulation is treated with borates, making it Class 1 Fire Rated. It will not support a flame and acts as a fire block within your walls.
-
Superior Sound Absorption: Because the Cyclone pump packs the material so tightly, it creates a massive "acoustic sponge" that kills echoes and blocks airborne noise like talking and music.
-
Vermin & Mould Resistant: The same treatment that makes it fireproof also makes it naturally resistant to pests and fungal growth.
-
Minimal Disruption: Most rooms can be completed in a single day, with no need to move out or strip the room to the studs.
