How can we help you?

Yes, up to maximum 3000 mm lengths and 1200 widths you can customize the dimensions freely.
Panels with length 2400 mm and longer have a maximum width of 600 mm.
You can save cost by using our standard formats: 600×600, 1000×600, 1200×600, 1500×600, 1800×600, 2400×600, 3000×600 mm.

We have many, but fixed widths and depths on our Linear Ribs. Length wise customizations are more flexible, but ribs are, depending on their dimension, produced in full lengths of 2400, 2550 or 2970 mm, and other lengths are cut from these. As an example, lengths of 1250 mm lead to up to almost 50% waste when cut from a 2400 length.

Yes, depths can vary from 130-400 mm and lengths from 400-3000 mm. For the surface on both sides, you can select any of our veneers with clear or pigmented lacquers. You can also design these surfaces with laminates or painted with solid colours. All 3 visible solid wooden lipping’s on the edges will normally come in matching wood species, but contrasting looks are possible too.

Yes, the Feltfon range is very customizable, and we love the input from our creative customers. Normally designers rework one of our existing solutions regarding form, colours and combinations with Gustafs other solutions, like wooden Linears. Regarding combinations, Gustafs Mix Ceiling system is the ultimate unified installation system.

We will use the same wood specie, but there will be a slight deviation in structure and colour impression between solid wood and sliced veneers.

The pictures give a good impression of veneers and colours, but they will vary, depending on the quality and calibration of your screen. Wood is also a natural product, and each wood veneer is unique. Variation in colour, pattern and texture is a natural part of the look.

Working with wood for more than 100 years, we have developed Gustafs Selected, a joint technique ensuring a vibrant yet harmoniously consistent appearance across larger claddings. Crown and half-crown cut veneer flitches are reverse slip-matched. Gustafs Selected is our standard and simplifies the installation by reducing the need for on-site planning. Let us know if you want straighter grain directions, so we can help you to achieve the best result with rift cut veneers.

There are no differences regarding the surface options or for the classifications of the acoustics and fire safety. Most solutions have some limitations regarding the maximum dimensions for ceilings use, but other wise the installation system will be different.

Gustafs is a fully owned brand of Gustafs Scandinavia AB. Our production is located in a small village called Gustafs, in the heart of Sweden. We produce 100% in-house.

The sound blocking characteristics of Gustafs solutions are limited, but the heavy density of our fibre gypsum-based products is more beneficial compared to lighter wood-based materials like MDF and Plywood.

Gustafs solutions with fibre gypsum cores have been produced and installed, with almost the same design and construction, since 1986. The wood veneer on our solutions ages beautifully and the core is dead, not influenced by time. We guarantee a minimum lifetime of 50 years!

Yes, all Gustafs solution using a fibre gypsum core are non-sensitive to variations in temperature and humidity. The dimensions will be stable over time and in combination with Gustafs Capax installation components we guarantee zero spacing installations. For panel on 4 sides, for Linear ribs in the in-line joints.

Also, Gustafs Feltfon solutions, using the rPET Acoustex material can be installed with zero spacings in all directions, without the risk of shrinking apart over time.

Yes, you can. Please be aware that direct (typical wall) installation with Gustafs Capax system adds minimum 4 mm to the total installation depth for panels, 17 mm for Linear Ribs, and 10 mm for Feltfon designs. Most walls and ceiling will need levelling works to get a good final and flat result.

Gustafs products with a fibre gypsum are designed for indoor use, but we have done many installations in car parking houses, entryways for shops and offices, underground stations, etc. All these are semi outdoor climates and always protected from direct rain and direct sun light. Contact us before prescribing Gustafs products for such environments.

All Gustafs Feltfon solutions and Gustafs Lamellow Spa panels can be installed in outdoor environments. These solutions are not sensitive to natural cold or hot temperatures or water. Feltfon colours will gradually fade over time when used on walls where they will be exposed to direct sunlight. Soffit use for example will not fade the Feltfon colours.

Yes, no problem to use our products on doors. We can also supply the door manufacturers with veneer from our in-house veneers shop, for matching designs on walls and ceilings.

Yes, but in varying ways depending on the solution.
– Panels need a slotted backside for radius down to 1000 mm. The veneer direction should be along the curved surface.

– Linear Ribs can be installed on curved surfaces without any extra post treatment.

– Lamellow and Lamellow+ panels do flex down to a radius of minimum 1000 mm.

– Lamellow Flex and Lamellow Flex+ can be curved to radius 300 mm, convex and concave.

– Modules needs to be produced curved in their final shape.

– Feltfon Linears cannot use the Capax system for curved walls or pillars, but tailored solutions for all kind of curved situations are easily achieved.

Yes, maximum 1 hole per ceiling panel with a centre position and accessories with a weight of maximum 1 kg. Maximum panel width 600 mm.

Gustafs Nano Panels. Regarding their acoustic properties, Gustafs Nano solutions are less reliant on insulation and air voids behind the panels.

Gustas has 3 different demountable ceiling solutions in its Capax assortment, and this is how they work.
1. The Gustafs T24 Panel system for ceilings has a fully concealed and demountable carrier system. A clever small upwards and sidewards movement of the panels releases them one by one from the grid. No additional space above the installation grid is needed. Putting the panels back in place is done in the opposite order.
2. The Gustafs CEILING-CD system for Linear Ribs let you demount each rib by a small sidewards movement, this releases the 5 individual clips that hold one rib in a length of 2400 mm. Re-installing is done by a straight upwards movement so that the clips will lock in place.
3. The MIX ceiling system holds Feltfon solution, Blayde baffles, Linear Ribs in various dimensions and shapes, as well click-on LED lamps.
Feltfon solutions are hold in place by firm friction and be pulling at the connection point, they will release. This process can be repeated many times.
The Blaydes and Linear Ribs can either be slided off one by one in the length direction, but this movement requires space in the length direction. Alternatively, you can create smaller demountable sections where you remove shorter lengths of the Blaydes or Linear Ribs that are installed with zero length spacings in both direction. Contact us for the technical drawings of these “hatches”.

Cleaning is performed with a dry mop or vacuum cleaner. On grease, fruit, wine, and coffee stains, use synthetic detergent without ammonia. Blood stains are removed using cold water. All lacquered surfaces and Gustafs Acoustex/ Feltfon are approved for cleaning products containing up to 70% alcohol.

Yes, you can but take the following in regard.

• Sub-constructions should support Panel and Linear products every 300 mm instead of the standard 600 mm. We recommend the use Gustafs EHIP panels.

• Deeper Linear Ribs are more sensitive to side impacts than Ribs with little depth.

• Corners are extra exposed to impact, and we recommend the use of protecting corner profiles like Gustafs Capax 3229, 3239 and 3208.

• Surfaces exposed to impact from pointy objects, like mobile hospital beds, should be protected additionally.

Yes, as all lacquered finishes can be cleaned with products containing up to 70% alcohol, they are very suited for use in health care rooms.

For sports hall we recommend Gustafs EHIP panels or Gustafs Feltfon.

For swimming halls, we recommend Gustafs Feltfon or Lamellow Spa.

Yes. Gustafs products with fibre gypsum cores have a high specific weight and will reduce vibrations to a minimum for optimal sound reflections, making them perfectly suited for concert halls. Combining sound reflective and absorbing mechanisms in one and the same solution, provides the perfect tool for every acoustician. Gustafs robust installation system Capax, contributes to even less-resonating claddings.

Yes, you can re-use Gustafs solutions, as all are, or are available in, fully demountable and re-usable versions, both for walls and ceilings.

Gustafs Panels and Linears with a gypsum core have a high thermal mass and are good in storing thermal energy. They will help to even out daily fluctuations in room temperature and save power consumption. Using lighter colours in your design will help day light to reflect further into the room and reduce the need for artificial lighting.

Yes, often it does. Gustafs fire certifications with class A2-s1,d0 are valid regardless of what veneer type is used. High Pressure Laminates and veneers with acoustic Nano perforations reach class B-s1,d0 and not higher.

Gustafs Feltfon surfaces have a B-s1,d0 classification.

It can have effect, but Gustafs fire classifications are always valid with our lacquers, pigmented lacquers, stains, oils, or paints.

Yes. The panels fire safety is not affected by the acoustic perforations as the panels core is a non-combustible material. An air void behind a perforated panel could give a chimney effect and perforated panels must be backed with a mineral wool insulation to remain the fire classification valid.

Gustafs Linear Ribs have been tested while installed with a spacing and with an air void, alternatively with a void filled with a mineral wool. That’s why we can offer rock-solid fire classifications for all types of installations.

Linear Ribs are wrapped with veneer and the total surface of veneer per square meter, exposed to fire, is larger compared to the veneer surface on panels.

Room acoustics are set by the shape and volume of the room and additionally by the sound absorption of the wall and ceiling claddings. Also, furniture and other obstacles will influence. We recommend consulting an acoustician for the best result.

Yes, in our in-house Nano hole production, we punch away circular material hats with a diameter of 0,5 mm. 300.000 pieces per square meter. The material is removed and not only pushed sideways, which is the case when cheaper techniques using pointy needles are used.

Yes, but only if the wrong coating techniques are used. Being Nano Acoustic specialist and having it all produced in-house, we have developed several methods, so you can add treatments from clear lacquers to dark pigmentated lacquers onto Nano perforated surfaces, without making the holes smaller.

Sound waves are transformed into heat energy already when penetrating the small Nano holes. Compared to large hole perforations, Gustafs Nano solutions are less reliant on the insulation and air void behind the panels.

Gustafs Panels or Linear Ribs do not absorb sound themselves, but the round hole perforations or the spacings between Gustafs Linear Ribs allow sound waves to reach the acoustic felts and the sound absorbing insulation. Gustafs Nano, Gustafs Feltfon and Gustafs Lamellow do absorb sound as they are, and need less added insulation materials behind them to reach comparable results.

Roughly, insulation does absorb sound twice as effective as an air void. To achieve approximately the same result, an air void needs to be double as deep as insulation. Apart from that the density and structure of the insulation are other parameters for sound absorbing.

Our tests have not been able to show significant and measurable differences between low and high depths of ribs. The spacing between the ribs makes the difference. Varying Rib depth can have an effect on the diffusion and reflection of sound waves.

No.
