1.
Before the floor is delivered to the installation site, doors and windows must be installed in the building, and all “wet” work must be completed, e.g. plastering, partition wall construction, painting, etc. If there are basements under the floor installation site in the building, they must be dry and well ventilated. Hybrid floors can be installed in all living areas such as rooms, bedrooms, kitchens and bathrooms, as well as in most public spaces.
Packages containing hybrid boards must be handled with care during transport and unloading to avoid any mechanical damage. Hybrid boards
in their original packaging should be stored in a dry place, in a horizontal position, on pallets or wooden beams. There must be a free space of at least
75 mm between the hybrid board package and the ground. Hybrid boards should be stored in their original package in the room where they are to be laid for at least 48 hours to allow them to acclimatise. The air temperature should be between +18°C and +24°C. Relative air humidity between 45% and 60%.
2.
The moisture content of the wooden substrate (or wood-based panels) should not exceed 12%. The moisture content of concrete substrates without underfloor heating systems should not exceed 2%, and that of anhydrite substrates should not exceed 0.5%. The measurement results should be documented.
3.
When installing hybrid boards on underfloor heating, the moisture content of the concrete substrate should not exceed 1.8%, and that of the anhydrite substrate should not exceed 0.3%. The measurement results should be documented.
4.
The maximum acceptable unevenness may be up to 3 mm, measured over a length of 2 m. Local unevenness should not exceed 2 mm over a length of 1 m.
5.
Before starting the installation of hybrid boards, the substrate should be swept or vacuumed. The substrate should be free of dust, debris, paint, lacquer, wax, grease, oil, hardeners, sealants, solvents, sand, adhesive residues, grease and other foreign matter.
6.
The substrate should be dry, stable, free of scratches and cracks, and clean with no visible dirt. Cracks
and defects in the cement or anhydrite substrate should be filled. In the case of floating installation on ceramic tiles, joints wider than 5 mm and deeper than 2 mm must be filled.
For adhesive installation, fill all joints between tiles with filler and refer to the adhesive system manufacturer’s guidelines.
Information on the adhesive system recommended for installing hybrid floors can be found at www.barlinek.com
Plywood, OSB boards and chipboard must be structurally sound and installed in accordance with the board manufacturer’s recommendations. We recommend installing wood-based boards in two layers, joined with wood screws. The edges of one layer of boards should be installed in a staggered pattern in relation to the second layer. The wood-based board substrate must provide adequate rigidity and support for the proper installation of the hybrid floor. Board joints should be smooth and should not deflect or spring under load. All screw heads should be slightly countersunk below the board surface.
7.
For floating installation, use underlay with the following parameters:
CS – short-term load ≥ 400 kPa
8.
Hybrid boards must not be installed on existing soft carpet coverings, soft PVC coverings, carpets and other similar materials.
9.
During installation, hybrid boards from several packages should be used, selecting them in terms of colour to achieve a balanced visual effect of the floor.
When ordering flooring, order approx. 3% more boards than the measured surface. Where there are many angles in the room or obstacles, hybrid boards are installed diagonally across the room or at joints with ceramic tiles, and approx. 10% extra may be required.
10.
Before installation, the investor or installer should check the hybrid boards and verify that they comply with the order.
The boards should be checked for quality, finish, gloss, colour and mechanical damage (all information can be found on the label, instructions or product card). In case of doubt, the investor or installer should not use any hybrid board that they consider unsuitable for installation and should immediately contact the seller. Installation of a damaged hybrid board that does not comply with the order, has visible defects or unacceptable visual characteristics will result in the loss of the Warranty.
11.
Heavy objects such as kitchen islands and furniture can be placed on the floor without the need for expansion joints around the fixtures.
However, it is necessary to make a perimeter expansion joint around fixed elements connected to the floor, e.g. plumbing and sewage systems.
12.
Recommended tools and materials for floor installation:
13.
The maximum dimensions of the floor plan of a house/flat at which a floating hybrid floor does not require expansion joints in doorways are 12 m x 12 m.
14.
Lay out the underlay for the boards. Adjacent strips of underlay should be installed tangentially to each other.
For floating installation, use underlay with the following parameters:
CS – short-term load ≥ 400 kPa
It is important that the underlay is able to withstand various types of loads throughout its entire service life. The use of underlay with lower parameters will result in faulty floor installation and loss of Warranty.
Barlinek offers a dedicated Extreme 1.5 underlay that meets the specified technical requirements.
15.
Start installation on the left side of the wall and continue to the right. The expansion gap should be at least 10 mm. Expansion wedges will help to maintain the same gap size. The expansion gap should be made along the perimeter of the room and around any other obstacles such as pillars, stairs, ceramic tiles, etc.
16.
Place the short edge of the second hybrid board against the edge of the first board. Make sure that the edges are precisely aligned. The connected boards must be precisely aligned in a straight line.
17.
Gently tap the edge connection with a rubber mallet and fasten the lock in the order of tapping 1 and 2. When the lock is fastened correctly, the surface layer of the boards should be flush and there should be no visible difference in level between the connected elements.
18.
A hand saw or electric saw can be used to cut hybrid boards. Remember to leave an expansion gap of at least 10 mm after cutting the last hybrid board. The recommended length of the last cut board (A) in the first row of flooring should be at least 200 mm. If the cut piece (B) is longer than 200 mm, it can be used to start installing the second row of flooring. The distance between the end joints in two adjacent floor strips should be at least 200 mm.
19.
Insert the first hybrid board in the second floor strip at an angle of approx. 30° into the lock of the board in the first floor strip.
The minimum length of the board being installed should be at least 200 mm.
20.
If the board does not fall freely during installation, tilt it alternately up and down and press it lightly.
21.
Tap the board on the long side with a tapping block. When installing hybrid boards, always tap the locks on the long side.
22.
Insert the second board in the second row of the floor at an angle of approx. 30° into the lock of the board installed in the first row.
23.
Push the board towards you so that the short edges are touching.
24.
After lowering the board being installed and connecting the short sides, fasten the lock by tapping with a hammer in the order 1 and 2.
25.
Tap the board on the long side with a mallet. When installing hybrid boards, always tap the locks on the long side.
26.
For radiator pipes in the hybrid board, draw holes with a diameter 20 mm larger.
27.
Cut the holes in the board. Draw
a line through the centre of the holes and cut the board with a saw.
28.
Glue the cut piece of board back in place using construction adhesive.
29.
Use a metal claw to hammer in the last row of hybrid boards.
30.
After installing the entire floor surface, install decorative skirting boards. Skirting boards should only be attached to walls using mounting clips or assembly adhesive.
31.
Cross joints in adjacent floor strips are unacceptable.
The minimum recommended offset of joints on the short edges of hybrid boards in adjacent floor strips must be greater than 200 mm.
32.
Important: There is no need to make an expansion joint in passages from one room to another. We only make it on walls and other elements permanently built into the building, e.g. stairs, columns and other obstacles. The maximum dimensions of the floor plan of a house/flat where a floating hybrid floor does not require expansion joints in doorways are 12 m x 12 m.
33.
Hybrid boards can be installed in bathrooms and other rooms where water spillage may occur.
In such rooms, we recommend using an adhesive installation system. In this case, the size of the perimeter expansion joint can be reduced to 3 mm. If the boards are glued to the substrate in other rooms, there is no need to make an expansion gap in the door frame. If hybrid boards are installed as a floating floor in other rooms, it is necessary to make an expansion gap in the door frame with a minimum width of 5 mm (adapted to the type of masking expansion strip).
Use the recommended adhesive system to glue the floor. For more information, visit barlinek.com
In a floating installation system, always make a 5 mm wide expansion gap around the perimeter.
In bathrooms with underfloor heating, regardless of the installation system chosen (floating or adhesive), an expansion gap must be made in the door frame to separate the bathroom from other rooms.
Expansion joints must be used around walls, shower trays, bathtubs, toilet bowls and other obstacles permanently attached to the floor.
Important:
Hybrid boards must not be installed in shower trays, bathtubs, saunas, swimming pools and other similar areas exposed to prolonged contact with water.
34.
When gluing hybrid boards to the substrate, use dedicated adhesives. After installing several rows, press down on the floor with heavy objects (e.g. unused packs of boards).
Depending on the adhesive system selected, use trowel B1, B2 or B3.
35.
It is very important that the floor cooling system is equipped with appropriate control systems that prevent water vapour from condensing on the floor surface. To prevent this, the temperature of the cold water in the pipes should not fall below a specified value. Each room with a floor cooling system should be equipped with a sensor that calculates the relative humidity of the air in relation to the temperature on the surface of the boards and cuts off the cold water supply before the so-called dew point is reached, i.e. when water vapour condenses on the surface of the boards.
Thermostats in rooms should not be set to a temperature lower than 23°C. In addition, the difference between the temperature on the thermostat and the temperature in the room should not exceed 5°C. Example: room temperature 30°C, temperature set on the thermostat min. 25°C.
The floor cooling system should be protected against the water temperature in the system falling below +18°C.
The maximum thermal resistance of the installed floor together with the underlay must not exceed R≤0.15m2K/W. In order to achieve the minimum thermal resistance, Barlinek recommends a glue-down floor installation system or the use of an underlay with a very low heat loss coefficient: EXTREME 1.5
48 hours before installing the floor, turn off the underfloor heating. After installing the floor, you can turn it back on after 48 hours.
The moisture content of the cement screed should be a maximum of 1.8% and that of the anhydrite screed should be 0.3%. Measurements should be taken using the carbide method, known as CM.
The remaining installation and usage parameters are in accordance with the installation instructions and the terms of use and care for hybrid floors. For more information, visit www.barlinek.com
The decision on the possibility of using underfloor cooling requires a heat balance to be drawn up at the design stage. Omitting this stage may lead to the incorrect selection of equipment and insufficient performance of the entire cooling system.
36.
Hybrid floors can be installed on water or electric underfloor heating systems using adhesive or floating installation methods.
For floating installation, use an underlay with the following parameters:
CS – short-term load ≥ 400 kPa
IMPORTANT!
Before laying hybrid boards on underfloor heating, it is necessary to heat the screed and draw up a heating report. This applies only to new, unheated screeds in which the heating system is embedded. The screed heating process should also be carried out in summer. Information on screed heating and the report are available at www.barlinek.com. If a heat pump and floor heating programme are installed, we must perform a floor heating cycle in accordance with the programme . When bonding to the substrate, follow the recommendations of Barlinek, the manufacturer of adhesive systems, available at www.barlinek.com.
The maximum temperature on the surface of the hybrid floor during operation of the heating systems should not exceed 27°C.
The moisture content of the screed in the case of installation on underfloor heating should not exceed:
In order to prevent uneven operation of the hybrid board core, the entire floor surface should be heated. This also guarantees the greatest comfort of use (no colder spots on the floor) .
Floors with underfloor heating must not be covered with carpets.
Furniture placed on underfloor heating, e.g. sofas, should have legs at least 10 cm high.
Do not start the heating system during installation. During the installation of hybrid floors, the underfloor heating system must be switched off and the surface temperature of the subfloor (screed) should be between +18°C and +24°C.
The underfloor heating system should not be turned on until at least 48 hours after the hybrid flooring has been installed.
During use of hybrid floors on floors equipped with underfloor heating, please note that any liquids spilled on the floor surface may evaporate more quickly. Therefore, any stains caused by liquids such as wine, urine, milk, etc. should be removed from the floor surface as soon as possible, as drying on the surface of the hybrid boards may cause permanent discolouration of the floor.
The height of the screed over the heating elements should be at least 20 mm.
