Knauf acoustic strips

3 products

Knauf acoustic tape is a self-adhesive polyurethane strip essential for decoupling metal profiles and reducing structural noise in partition systems. Poor perimeter sealing ruins the insulation of any wall. You can filter our website by category or price range to find the exact format your project requires. At Brikum, we ensure fast shipping so renovators and DIY enthusiasts can achieve completely airtight finishes without delaying the work.

Guide to choosing your perimeter insulation without making a mistake

Having good boards is useless if sound gets through the profiles. If you are going to buy different models to soundproof a space, our technical team recommends checking 3 basic details before choosing:

  • Channel or stud width: The strip must cover the base of the sheet exactly (they are usually 46 mm, 50 mm or 70 mm) to eliminate acoustic bridges at the source.
  • Polyurethane density: The greater the foam's elastic memory, the better it absorbs daily physical impacts.
  • System compatibility: Use consumables that fit well with the Knauf plasterboard you plan to screw on afterward.

Quick comparison of tapes for metal framing

So you do not get confused while browsing our online store, here is what each exact product is used for:

Product Main use Material Ideal application
Knauf acoustic tape Decoupling structures. Elastic foam. Perimeters (floor, ceiling and walls) of partitions.
Knauf paper tape Joint reinforcement. Microperforated paper. Smooth joints between plasterboard sheets.
Knauf corner bead tape Protection against impacts. Paper with aluminum strips. Exposed outer corners and sharp edges.

Installers are clear about it. Trying to save a few cents on the price of perimeter adhesive ends up being very expensive when the soundproofing has to be redone. Original Knauf acoustic tape stands out for the strength of its acrylic adhesive. It does not shrink, does not come loose in damp areas and keeps the profile firmly in place before final anchoring with screws.

How to install the tape step by step

Follow these 4 steps to comfortably comply with building regulations during your renovation:

  1. Clean the surface: Wipe the back of the galvanized sheet to remove dust or factory oils.
  2. Apply in a straight line: Unroll the tape gradually, centering it properly on the web of the metal profile.
  3. Anchor it to the wall: When fixing the profile to the structural slab, the pressure from the plug or screw will compress the foam, sealing the gap 100%.
  4. Close the structure: Install the panels and tape the joints using Knauf filler and paper tape.

Frequently Asked Questions about Knauf acoustic strips

What difference in sound insulation is there when using a Knauf acoustic band compared with screwing directly?

Gain up to 4 dB of overall sound insulation. If you don't install this perimeter tape, floor vibrations travel directly through the sheet metal to the plaster. This creates an acoustic bridge through structural transmission that negates any previous effort to soundproof the partition wall.

How many meters of tape do I need per square meter of board?

It is not calculated per square metre of wall. You only need to measure the linear metres around the perimeter of your structure (floor, ceiling, and the two supporting side walls). A standard 30 m roll is more than enough to frame a normal room of between 12 m² and 15 m².

Is Knauf corner bead suitable for corners that are not exactly 90 degrees?

Yes, without any problem. With very flexible aluminum strips integrated into the paper, you can bend it by hand to adapt it to wide or very tight angles. It’s the perfect solution for attics or partitions with unusual geometries where a traditional metal corner bead won’t fit.

Do I need to put polyurethane tape on the profiles of a continuous suspended ceiling?

It’s essential. You have to stick it to the back of the U-shaped or angle profiles that go against the perimeter wall, just before installing the ceiling furring channels. If you don’t, the impact noise from the floor above will travel down the walls to your new ceiling.
