Acoustic & Partition Joints We Seal

Even a tiny unsealed perimeter gap around a stud partition wall, floor track, soffit junction or service penetration significantly reduces airborne sound insulation (Approved Document Part E / BB93). Our CSCS and CITB SSSTS certified applicators work alongside drylining, fit-out and main contractors across the North West and UK-wide to apply high-density acoustic and intumescent mastic seals to partition perimeters, deflection heads, glazing frames and floor junctions.

Why Specialist Acoustic Sealing Matters on Site

Failing pre-completion sound insulation testing (Part E / BB93)

01

Sound leaks through unsealed 3mm to 10mm perimeter gaps at the base and head of plasterboard partitions. Continuous, full-depth acoustic mastic beads seal air paths and protect acoustic ratings.

Air-leakage and draughts failing commercial air-tightness tests

02

Sealing window interfaces, drylining perimeters and floor-to-wall junctions prevents air leakage and helps commercial buildings pass air-permeability testing.

Keeping pace with fast-track drylining and fit-out programmes

03

We deploy experienced CSCS/SSSTS mastic applicators from our Liverpool and North West base to keep ahead of plasterers, tapers and following trades.
