ISO-Acoustic Tape – The Loft Conversion Sound Insulation Tape

Why Use Sound Insulation Tape in a Loft Conversion?

Loft conversions are one of the most common projects where our acoustic joist tape is used. When applied to timber, steel stud or zinc joists, ISO-Acoustic Tape isolates the structure, which means sound waves and vibrations can’t easily travel through the building.

By fitting acoustic tape during a loft conversion, you can:

• Dramatically reduce airborne sound between floors
• Cut down on impact noise like footsteps and creaks
• Helps reduce noisy floorboards
• Stop flanking noise travelling through joists and party walls
• Help meet Part E soundproofing requirements
• Very quick and easy to install

It’s quick, easy, and makes a huge difference to the performance of walls and floor systems in lofts.

ISO-Acoustic Tape Benefits

• Strong self-adhesive backing – quick to apply, no messing about
• Works on all wall, floor and ceiling systems
• Tested and proven to reduce noise by up to 80%
• Helps meet Building Regulations Part E for soundproofing
• Suitable for timber, steel stud & zinc joists

One builder summed it up perfectly:

“Does the job perfectly – its works so well, at least 80% reduction in noise and vibration – I used it on both chipboard floor on joints and plasterboard in our loft conversion – wow – what a difference – totally recommend this quality product – its deffo a professional type tape not a cheap copy”

How to Install Acoustic Joist Tape

Installing ISO-Acoustic Tape is straightforward:

1. Prepare the surface – clean away dust and debris.
2. Apply the tape – run it along the top of each joist.
3. Press firmly – make sure it bonds properly.
4. For damp joists – staple the tape down until dry.
5. Fix your boards – but don’t over tighten screws or countersink.

Once applied, you can carry on with your loft conversion as usual – just with much better sound insulation built in.

Other Uses Beyond Loft Conversions

Although lofts are the most common project, ISO-Acoustic Tape is also ideal for:

• Garden rooms and extensions – soundproofing walls, floors and ceilings
• Studios and music rooms – reducing echo and airborne sound
• Roofing projects – applied to battens and joists before plasterboard or floorboards
• General construction – anywhere you need to stop flanking noise

Its flexible, overlap friendly design makes it easy to fit in all sorts of builds.
