Linear Rib-S

ACOUSTIC SLATS FOR WALLS AND CEILINGS

Gustafs Rib-S with a 0,5 mm edge radius, lets you create spaces with stunning wood slatted ceiling or wall panels. Utilizing real wood veneer Gustafs Linear Rib System integrates the Capax, Quick-Up installation system to achieve a reliable, labour saving and exclusive interior finish. Many parameters can be adjusted individually before losing the advantages of a standard solution. You can vary the core, the veneer, the colour, the dimensions, open or closed gaps, coloured gaps. Gustafs timber cladding panels can also be used in curved installations.

Material

Made with a fire resistant fibre gypsum high density, 1200 kg/m³ core and a natural wooden veneer. An all-natural product.

Acoustics

With a standard installation our Linear Rib gives a large open area of 24% which warrants for a good sound absorption. By increasing the installation interval even higher sound absorptions can easily be achieved. Our acoustic felt, Acoustex is 0,2 mm, and available in black, white and grey.

Fire Reaction

Gustafs Linear Rib System is made for public spaces. The individual parts and the final installation has B-s1,d0 – which means little or no contribution to fire.

Gustafs Linear Rib acoustics

Quality in room acoustics requires a well-balanced combination of absorption and reflection. Gustafs Linears will deliver perfect recipes and provide good sound diffusion too. Simply adjust the room acoustics by varying the spacing. These Helmholtz absorbers are typically used to reduce mid to medium high frequencies.

FIRE CLASSIFICATION
Reaction to fire

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

The fibre gypsum core of Gustafs panels is regarded an inherently none-emitting source of VOCs, just like stone, ceramic, metals, glass and concrete. The panels are also completely impregnation-free and that is why our panels are naturally very low emitting, guaranteeing a healthy room air quality.

5  natural benefits of the fibre gypsum core

Gustafs Linear Ribs are produced with a high-density, reinforced fibre gypsum core having inherent properties regarding dimension stability, emissions, sustainability, fire safety and acoustics. These 5 fundamental demands in today’s modern building industry effectively eliminate most traditional wood-based alternatives.

Stability

Unaffected by indoor climate changes, fibre gypsum doesn’t bulge, warp or swell – making zero-spaced joints perfectly viable. The ribs will stay stable and straight, with a beautiful end result over their full life time.

Fire Safety

Non-combustible and homogeneous by nature, fibre gypsum doesn’t need chemicals to achieve its fire rating. A Linear Rib with a wood veneer wrapping still consists of 97% fibre gypsum and has a fire classification of B-s1,d0.

Acoustics

Acoustically, the use of wall cladding with a higher density is usually favourable compared to lighter materials. Fibre gypsum-based ribs are heavier than wood-based wall cladding materials and sound waves will not make them vibrate or resonate.

Sustainability

Thanks to the cores high density and low thermal conductivity, the ribs help to maintain room temperature, reducing the need for cooling or heating. Fibre gypsum contains of 94% recycled material. Even better is the fact that 17% of the total content comes from post-consumer recycled material, very important for the certification of buildings.

Emissions

Fibre Gypsum cores are extremely low emitting. One of the reasons is that they are produced without wood binders and automatically without added urea-formaldehyde or isocyanates. Interior Panels and Ribs, containing 97% Fibre Gypsum, will per definition have very low TVOC and formaldehyde emissions.
