ZIPS-Floor Module, sandwich-panel

1. Preparing the floor for installation

As a surface for mounting panel systems «ZIPS-Floor» can serve as a floor slab or screed. To minimize the space losses it is recommended to disassemble the old floor construction. Before installation, the floor surface should be thoroughly cleared. The floor must be flat and smooth. In case of irregularities or the presence of defects and inhomogeneities the layer of self-leveling from mixes must be done. The thickness of the screed is determined by the place.

2.Beginning instalation

To avoid straight contact of soundproofing floor with the side surfaces of the walls on the perimeter of the room, bond antivibration tape «Vibrostek-M» (100 mm width) in 2 layers. In case of «ZIPS-Floor Vector» soundproofing system the tape is pasted on the wall close to the floor, when «ZIPS-Floor Module» is used the tape is pasted 30 mm above the floor level. You can use acoustic silicon sealant «Vibrosil» as a glue, the sealant is applied in the «helix shape» with a plunger gun.

3. Laying vapor barrier

To exclude the of moisture penetration in the absorbent layer of the sandwich panels, the surface of the subfloor is closed with plastic reinforced film 200 microns thickness. The film starts on the walls to a height of 150 mm. The film has 100mm overlaps and should be fixed with reinforced tape.

4. Inststallation of sandwich panels

Each panel has 8 vibration-insulating pillars. The panel must be installed on the floor only via anti-vibration mounts. The installation is carried out from left to right. 1-panel ridges are cut short and the long side, all subsequent panels of the 1st series only on the long side. Panels connected to one another by means of a tounge-and-groove connection, tounge-andgroove joints are also held together with screws for gypsumfiber Board 3 x 25 mm, pitch of screws 150 mm.

5. Trim panels/Spacing of joints

With the closure of a number of the panel can be cropped. In this case, a layer of gypsum sheets is cut by jigsaw, a layer of insulation material is cut with a sharp knife. The trimmed portion of the panel goes to the next row. The portion of the panel length less than 300 mm is not used. The panels are stacked with an offset transverse joints in adjacent rows. The distance between joints shall be not less than 250 mm. If the last row of panels not cut a groove into the slots of the stacked strips of fiber corresponding width.

6. Using the optional S-poles and the offset of the existing pillars

Adjacent to the walls stripped portion of the sandwich panels is additionally relying on elastic elements – S-support. An additional elements apply only if the amount remaining in the isolation pad on the cut part is not enough for the stability of the panel.

7. Using the optional S-poles and the offset of the existing pillars

On the back side in the layer of insulation material is cut off a cube (60x60 mm). The hole is sealed with S-shape pillar and filled sealant «Vibrosil». If the existing isolation pad is shifted, unscrew it. If the pillar is moved it should be replaced with the cover made from sound absorbing plate of the same density and thickness as that used in the sandwich panel.

8. Installation of gypsum sheets

After installation of sandwich panels throughout the area arrange-floor flooring 2 layers of gypsum sheets with thickness of 10 mm each, with the overlap joints of the 1st and 2nd layers. The sheets are fixed with screws for gypsum-fiber Board 3 x 25 mm for 1-layer and 3x35 mm for the 2nd layer. The pitch of screws along the length and width of 200 mm and 400 mm respectively. When laying the sheets where twist screws, optionally stripped from chips and burrs with a putty knife or sandpaper. If during installation between gypsum sheets are formed by the gaps and cracks wider than 3 mm, you need to fill them acoustic silicone sealant «Vibrosil»

9. A finishing plywood layer

To provide additional strength and stability of the system «ZIPS-Floor», and also to prepare the finish flooring the polished sheets of waterproof plywood (18mm thick 1,5x1,5mm format) are mounted over gypsum-fiber sheets. The surface is Pre-treated with primer. The area is covered with a layer of rubber mastic evenly using a notched trowel.

10. The fastening of the plywood

Plywood sheets cut into 4 equal parts and placed with a gap of 3-5 mm. The sheets are fixed with screws on wood 3,9х41mm. The diameter of the drill holes is slightly larger than the diameter of the screw, hole countersinked under the cap screw, which ensures that no squeaks in the future use of the floor. The pitch of screws along the length and width of the sheet of 300 mm. After tightening the screws holes sanding by sandpaper. Full mastic drying time at t=+18°C is 24 hours.

11. The final stage

At the final stage of mounting the excess protruding tape «Vibrostek-M», and a polyethylene film are cuted with the finish layer of plywood. The joints and the gaps between the plywood sheets are filled with acoustic silicone sealant «Vibrosil».

12. Laying the finishing material

Put finished floor and mount the baseboard. The finish flooring could be parquet board, laminate, linoleum or carpet. The baseboard is screwed to only to the floor or to the wall.
