- Carrying capacity 120 kg. per mounting
- Economical and timesaving
- No cold conductor / no line loss
- Optional positioning in outer or inner wall
- Remember pre-drilling through frame and fittings
K-Wall is made from high quality HDPE (high density polyethylene). Additives are added, which secure lifespan and optimal strength, without deformation.
The K-Wall series makes it easy to fit doors and windows in most types of building work and, at the same time, the new BR15 insulation regulations are respected.
K-Wall is obtainable in two variations with two sizes each:
- K-Wall-28i: For building-in with 28 mm flange
- K-Wall-50i: For building-in with 50 mm flange
- K-Wall-28e: For retrofitting with 28 mm flange
- K-Wall 50e: For retrofitting with 50 mm flange
K-Wall is used in connection to fit of door- and window frames, where there is a need for firm and strong support for frame screws. K-Wall is manufactured of HDPE, which is why it doesn’t create a cold conductor like for instance a metal mount would do. K-Wall is ideal for forward movement of doors and windows in connection to external re-insulation.

Acoustics
Acoustics play an increasingly important role, when it comes to indoor climate in both new constructions as well as renovation of older buildings.
With a step sound reduction of up to 4 dB, Knudsen Sound Wedges and Sound Reducer make it possible to comply with the highest demands presented for reduction of step sound in floor separations, in an easy and economical way.
On top of that, informative measurements show that a considerable reduction of airborne sound is obtained.
New!
The Sound Wedges now all come with our newly developed soundproofing sole.
The sole still provides the best step sound insulation - with minimal compression.
