KNOWLEDGE HUB / CORE

5 natural benefits of the ceramic composite core

The slats of Gustafs Lamellow+ Cera are produced with a high-density, reinforced ceramic composite core having inherent properties in terms of dimension stability, emissions, sustainability, fire safety and acoustics. The slats are therefore ticking every box regarding these 5 fundamental demands in today’s modern building industry.

Stability

Unaffected by indoor climate changes, both the rPET Acoustex felt, and the ceramic composite doesn’t bulge, warp or swell – making large panels and zero-spaced joints perfectly viable. The end-result will be beautiful and remain so over the full lifetime.

Fire Safety

The non-combustible ceramic composite core of the ribs, nor the Gustafs Acoustex PET felt backing need chemicals to achieve their fire rating. The complete Lamellow+ Cera panel holds a true fire classification B-s1,d0.

Acoustics

Acoustically, the use of a wall cladding with a higher density is usually favourable compared to lighter materials. Ceramic core-based ribs are heavier than wood-based solutions and sound waves will not make them vibrate or resonate. The Gustafs Acoustex backing has superb sound dampening qualities.

Sustainability

The high-density core of the Lamellow+ Cera ribs has a low thermal conductivity, and stabilizes the room temperature, reducing the need for cooling or heating. The Lamellow+ Cera ribs contain 17% post-consumer recycled material and the acoustic felt minimum 50%, very important for LEED or BREEAM certification of buildings.

Emissions

The ceramic composite core of the Lamellow+ ribs is extremely low emitting. One of the reasons is that these cores are produced without wood binders and automatically without added urea-formaldehyde or isocyanates. Also, the PET acoustic felt is very low emitting, resulting in a overall product with per definition very low TVOC and formaldehyde emissions.

KNOWLEDGE HUB / CORE MATERIALS

Installed directly on an existing wall or ceiling.

The Lamellow+ Cera acoustic panels are really simple and quick to mount, directly on any existing wall or ceiling. Depending on the total construction of the installation, sound absorption class A or D will be reached, but all constructions will achieve fire safety class B-s1,d0.

 

WALL / CEILING
CEILING T24 SUSPENDED
CEILING T24 DA

Acoustic class A

To reach acoustic absorption class A for walls, add 45 mm mineral wool insulation behind the panels and for suspended ceilings use Gustafs T24 Capax system to create a 200 mm air void, no additional insulation needed.

Acoustic class D

For acoustic absorption class D, install directly to the wall or ceiling.

Fixtures

Depending on the sub-construction, screw or nail in the felt between the ribs or use glue. Use screws and nails in colours matching the felt.

VERTICAL OR HORIZONTAL

Lamellow panels can be installed both vertically or horizontally.

Cut the acoustic panels to fit your wall or ceiling. Cut the slats with a sharp saw and the acoustic felt with a carpenter knife.

With our low emissions, you can breathe out.
And everyone else can breathe in.

The ceramic composite core of Gustafs Lamellow+ Cera ribs and the Acoustex felt backing are regarded inherently none-emitting sources of VOC’s. These naturally very low emitting qualities plus the impregnation-free fire safety of the Lamellow+ Cera panel, guarantee a healthy room air quality.
