The number of different panels per decor varies depending on the product line:

• ORIGIN: 8 different panels in format 2025 x 244 mm
• PERFECTION: 8 different panels in format 2025 x 244 mm
• AUTHENTIC: 8 different panels in format 1845 x 244 mm
• CHEVRON: 6 different panels in format 1380 x 329 mm
• EVOLUTION: 10 different panels in format 1380 x 193 mm
• LIBERTY: 10 different panels in format 1380 x 193 mm

Tip: The individual panels differ from each other in colour. The best effect is achieved when they are mixed during installation. We recommend randomly installing panels from four boxes at the same time.

Yes. GRAND SELECTION offers skirting boards and stair noses in the same decor. This applies to the ORIGIN, PERFECTION and AUTHENTIC product lines (not to CHEVRON, EVOLUTION and LIBERTY). All skirting boards are also perfectly colour-matched with the panels. Universal waterproof skirting boards in white (RAL 9016) are also available. You can find more here on our accessories page.

The surface of GRAND SELECTION floors inhibits the growth of microorganisms. In other words: Bacteria cannot multiply on the surfaces of our floors. This is also confirmed by tests carried out by the Hohenstein institutes as per ISO 22196:2011.

All GRAND SELECTION floors meet the safety requirements of EN 14041 and have been awarded the technical classification DS. This means the dynamic coefficient of friction is > 0.30 in dry, clean conditions.

As all GRAND SELECTION floors comply with the highest usage class (AC 5/33), they can also be installed in most medium-sized commercial spaces, e.g. offices, schools, shops, museums or entrance halls.

Damage caused by the absence of protective mats or similar is not covered by the warranty. Therefore, the use of protective mats or other protective devices for hard plastic or metal rollers is necessary to avoid mechanical damage. However, protective mats are not absolutely necessary if using soft and clean rubber wheels.

Yes. All floors that leave the factory in Menznau have excellent hygienic properties, so the product can be used in all interior spaces without any problems. The GRAND SELECTION floors were also tested for volatile emissions. Tests in independent laboratories confirm these properties with the best classification A+ for indoor products. Our products are therefore also ideally suited for allergy sufferers.

All organic materials emit VOCs, which is a purely natural phenomenon. GRAND SELECTION floors, however, have very low VOC emissions thanks to the fact that they are made from natural raw materials. The GRAND SELECTION floors thus meet the highest requirements and are FloorScore and GREENGUARD Gold certified.

Yes, definitely. GRAND SELECTION floors are suitable for underfloor heating (H₂O). Heating system manufacturers allow floor coverings with a maximum thermal resistance of up to 0.15 (m²*K)/W.

The thermal resistance (R) of the floor depends on the thickness of the panels and is listed below:

• 14 mm thick: 0,1 (m²*K)/W
• 8 mm thick: 0,059 (m²*K)/W

Good to know: All GRAND SELECTION panels are also suitable for rooms with underfloor heating (H₂O). Heating system manufacturers allow floor coverings with a maximum thermal resistance of up to 0.15 (m²*K)/W. The rule of thumb: The lower the thermal resistance, the faster the floor heats up. The thicker the panels, the longer the floor maintains temperature.

Our products are available throughout the world from certified KRONOSWISS specialist partners. There you can take a close look at the current collections in exhibitions and showrooms. The companies working with us offer a comprehensive and professional service with advice, transport and installation of the floor. You can find the addresses of all GRAND SELECTION dealers on our website at «Dealer search».

No. Samples must always be ordered via a certified KRONOSWISS specialist partner. They can get you the samples, hand them out straight away or have them delivered to your home. The samples are fragments of the panels, so you can closely examine all the features here, such as colour or surface texture. This makes it easier for you to choose a matching floor, also in terms of its colour coordination with your interior design.

The floor panels are stored in winter in unheated warehouses where the temperature can drop below zero. Before installation, however, panels must reach the temperature of the room where they will be installed. For our GRAND SELECTION floors, we therefore recommend a 48-hour acclimatisation of the originally packed boxes at a minimum temperature of 16 °C and a humidity of 40 to 65 %.

Yes. With floating installation, one or more panels can be easily replaced. It is recommended to have this done by a professional floor installer. For full details, see the complete installation instructions.

A floating floor is a floor that is not permanently connected in any way to the floor, walls or other structural elements of the building. The floor panels are only connected to each other and form a uniform surface. Since GRAND SELECTION flooring is made of wood that can naturally expand linearly, the dimensions can change due to temperature differences or changes in humidity in the room. However, this can easily be compensated for with the use of expansion joints.

With GRAND SELECTION you can freely choose between a floating installation or gluing. Here you’ll find the tested glue products and the respective manufacturers. Please note the instructions of the glue manufacturer.

First: Please always use an underlay. Our specially developed ProVent impact sound underlay has, for example, a moisture-repellent, insulating, noise-dampening and equalising function. If you do not use a ProVent underlay, you will need a PE film as a moisture barrier – especially when installing floor coverings on new subfloors. This prevents moisture damage in the upper and lower areas of the floor. Simply ask your preferred dealer about suitable materials for this type of floor underlay.

The recommended scrap is about 10 %. The allowance depends on the installation method (e.g. random installation), experience and the offset of the individual floor panels (offset by 1/2 or 1/3 of the panel length).

Size depends on the thickness of the panels.

The possible maximum floor area without expansion joints is:

• for 14 mm thick panels: 14 x 14 m
• for 8 mm thick panels: 8 x 12 m

Please remember: If larger areas are to be installed, make a threshold gap.

Yes. All GRAND SELECTION floor panels have the flammability class Bfl-s1 or Cfl-s1 according to EN 13501-1. This means they are classified as flame retardant.

The GRAND SELECTION panels are characterised by easy installation, which you can do yourself. See GRAND SELECTION panels installed correctly in the videos here.

Yes. GRAND SELECTION floors can also be installed in bathrooms and kitchens of flats with normal use without any problems. However, the floor is not suitable for complete wet rooms such as saunas, steam baths, showers or swimming pools. Also, based on our experience with floor panels, we do not recommend installing them under kitchen units as the load is too high and the function of the floating floor would be affected. Remember: Flexible silicone edges should be used to finish the edge or transition areas (according to DIN 18534-1) in the bathroom. Regular checks should also be carried out to ensure that the seals are intact and that the underfloor is not exposed. Please read your installation instructions carefully.
