TECSOUND FT55 AL Acoustic Pipe Wrap

TECSOUND FT55 AL Acoustic Pipe Wrap Technical Specifications

TECSOUND FT55 AL Acoustic Pipe Wrap is a flexible acoustic pipe wrap designed to reduce noise from soil pipes, waste pipes, drainage pipes, water pipes, ducts and service pipework. It combines acoustic mass, absorption and an aluminium foil facing to help reduce pipe noise and vibration.

Product Specification

Suitable Applications

TECSOUND FT55 AL is designed for pipe and duct acoustic treatment. It is commonly used for:

• Soil pipe soundproofing
• Waste pipe soundproofing
• Drainage pipe noise reduction
• Water pipe noise control
• Downpipe noise reduction
• Air conditioning ducts and vents
• Service risers and service voids
• Commercial, residential and renovation projects

Acoustic Use

TECSOUND FT55 AL is mainly used to help reduce pipe noise, including flushing noise, drainage noise, water flow noise and sound radiating from pipework.

The acoustic membrane adds mass, the felt layer helps absorb sound, and the aluminium foil facing provides a durable outer layer. When fitted correctly, the wrap helps reduce both airborne pipe noise and vibration from rigid pipework.

Typical Coverage Guide

Coverage depends on the pipe diameter, overlap allowance and installation method. As a guide:

• 50mm waste pipe — approximately 38 metres of 50mm pipework per roll, allowing for a small overlap.
• 100mm waste pipe — approximately 16.5 metres of 100mm pipework per roll, allowing for overlap.

Always measure the pipe circumference and add an overlap allowance before cutting the wrap to size.

Common System Uses

• Wrapping exposed soil pipes before boxing in
• Reducing waste pipe noise in bathrooms and ensuites
• Treating drainage pipe noise in flats and apartments
• Improving acoustic comfort in hotels, offices and commercial buildings
• Reducing service noise in risers, voids and plant areas

Important Performance Note

Pipe soundproofing performance depends on the pipe type, pipe diameter, installation quality, overlap sealing and whether the pipe is boxed in or left exposed. For higher performance, TECSOUND FT55 AL can be combined with a plasterboard boxing system and acoustic mineral wool inside the void.

For best results, overlaps should be sealed with aluminium-backed foil tape or suitable acoustic tape, and the wrap should be secured tightly around the pipe using cable ties or appropriate fixings.

Handling Advice

TECSOUND FT55 AL is supplied as a heavy acoustic sheet/roll with an approximate roll weight of 37kg. For larger sections or overhead service runs, we recommend working in pairs and cutting the wrap into manageable lengths before fitting.

How to Install TECSOUND FT55 AL Acoustic Pipe Wrap

TECSOUND FT55 AL Acoustic Pipe Wrap is designed to reduce noise from pipes, ducts and service runs by wrapping directly around the pipework. It is commonly used on soil pipes, waste pipes, drainage pipes, water pipes, downpipes, service voids and air conditioning ducts.

Installation is straightforward, but careful measuring, cutting, overlapping and sealing are important for the best acoustic result. The wrap should be fitted tightly around the pipe, secured properly and sealed at overlaps to help reduce sound leakage.

What You’ll Need

• TECSOUND FT55 AL Acoustic Pipe Wrap
• Measuring tape
• Sharp Stanley knife or utility blade
• Straight edge or metal ruler
• Cable ties
• Aluminium-backed foil tape or suitable acoustic sealing tape
• Gloves for handling
• Marker pen or pencil
• Mineral wool, if boxing in the pipework
• Plasterboard, MDF or suitable board, if creating an enclosure

Step 1: Prepare the Pipe

Before installing the pipe wrap, make sure the pipe surface is ready. The pipe should be:

• Clean — remove dust, dirt, grease and loose debris.
• Dry — avoid fitting the wrap around wet or damp pipework.
• Accessible — make sure you have enough space to wrap, overlap and secure the material.
• Stable — check that the pipe is properly supported before fitting the wrap.

Good preparation helps the wrap sit tightly around the pipe and makes it easier to secure the joints properly.

Step 2: Measure the Pipe

Measure the circumference of the pipe before cutting the wrap. Add an extra 50mm to allow for overlap. This overlap helps create a continuous acoustic layer around the pipework.

For example, if the pipe circumference is 315mm, cut the wrap wider than this measurement so the edges can overlap and be sealed securely.

Step 3: Cut the Wrap to Size

1. Mark the required size on the TECSOUND FT55 AL.
2. Use a sharp Stanley knife or utility blade with a straight edge to cut the material neatly.
3. For easier handling, cut strips into manageable lengths.

For most installations, keeping sections around 1.0m to 1.2m long makes the wrap easier to handle, especially around bends, joints, tight spaces and vertical pipe runs.

Step 4: Wrap the Pipe

Wrap the TECSOUND FT55 AL around the pipe with the aluminium foil side facing outward. Start at one end of the pipe and work along the run section by section.

1. Position the wrap around the pipe.
2. Pull it tight enough to sit securely against the pipework.
3. Make sure the edges overlap by the planned amount.
4. Keep the wrap neat and close-fitting as you work along the pipe.

Try to keep the acoustic layer continuous. Gaps between sections can reduce the effectiveness of the soundproofing.

Step 5: Connect Sections Carefully

Where separate sections of wrap meet, butt the edges together tightly where possible. Avoid leaving transverse gaps between sections, as these can allow noise to escape.

For the best result, stagger joints where practical and keep all connections neat, tight and fully sealed. Around bends and connections, cut smaller pieces if needed so the wrap can follow the shape of the pipework more accurately.

Step 6: Secure with Cable Ties

Once the wrap is positioned correctly, secure it using cable ties. As a guide, use cable ties approximately every 200mm along the pipe run.

The cable ties should hold the wrap firmly in place without damaging the material. Make sure the wrap cannot slide or loosen once secured.

Step 7: Seal the Overlaps

For best results, seal the overlaps and joints with aluminium-backed foil tape or a suitable acoustic sealing tape. This helps maintain a continuous barrier around the pipe and reduces the chance of sound escaping through gaps.

Press the tape firmly into place and make sure all overlaps, seams and joins are fully covered.

Step 8: Box In the Pipework, If Required

For higher-performance pipe soundproofing, the wrapped pipe can be boxed in after installation. This is especially useful for soil pipes, waste pipes, service risers and pipework in flats, bathrooms, ensuites, hotels and commercial buildings.

For improved results:

• Use a double layer of plasterboard or suitable acoustic board where possible.
• Fill the void around the pipe with acoustic mineral wool.
• Seal board joints and perimeter gaps with acoustic sealant.
• Avoid leaving open gaps around the enclosure.

This creates an additional soundproofing barrier and helps improve the overall acoustic performance of the pipe treatment.

Typical Coverage Guide

Coverage will depend on pipe diameter, overlap allowance and the number of bends, branches and joints. As a general guide:

Always measure your pipework before ordering. Allow extra material for overlaps, bends, branches, awkward areas and wastage.

Installation Tips

• Measure carefully — always add an overlap allowance before cutting.
• Use manageable lengths — shorter strips are easier to fit around bends and tight spaces.
• Keep the foil side outward — this provides the durable outer facing.
• Secure regularly — use cable ties around every 200mm to keep the wrap in position.
• Seal all overlaps — foil tape helps prevent sound leakage through joints.
• Box in for better performance — a lined enclosure with mineral wool can further improve results.
• Avoid gaps — pipe soundproofing works best when coverage is continuous.

Important Pipe Soundproofing Note

The final result will depend on the pipe type, pipe diameter, amount of exposed pipework, installation quality and whether the pipe is boxed in or left exposed. TECSOUND FT55 AL can significantly improve pipe noise control, but the best results usually come from combining the wrap with sealed boxing and acoustic mineral wool where space allows.
