Detailed information

Product detailed description

Polystyrene foam with high level of compressive strength - ideal for rooms with poor soundproofing

  • High load-bearing capacity
  • Very good impact sound reduction
  • Protection against rising moisture
 
The SELITAC® underlay range is one of our premium products. Manufactured from high pressure resistant extruded polystyrene foam, these underlays are impressive thanks to their outstanding performance data. From 2.2 mm for low installation heights up to 5 mm for excellent thermal insulation. SELITAC® underlays with AquaStop have an integrated vapour barrier to protect against rising moisture. They are certified by TÜV Rheinland and feature the Blue Angel to confirm their status as particularly environmentally friendly products.

Installing SELITAC® AquaStop:

A STEP-BY-STEP GUIDE

Before installation, please note: Check the base in accordance with CEN/TS 14472 and ensure that the quality of the base is suitable for proper processing. In general, the base should be clean, level, dry, resistant to tension and compression and should not contain any substances such as plasticisers, solvents or other diffusing substances. It must be ensured that the base is in a state of equilibrium humidity and that the CM value is below 2.0% (for cement screed) or below 0.5% (for anhydrite screed and anhydrite flowing screed). The processing instructions of the flooring manufacturer are to be observed as binding specifications.

  1. Cleaning the surface - Clean the surface thoroughly with a brush or vacuum cleaner. Remove any adhesive and paint residues completely.
  2. Laying out the first panelLay the first panel of the underlay flush with the wall over the entire width of the room. Make sure that the aluminium side is at the top.
  3. Masking jointsTo protect against moisture, seal possible joints with SELITstop® Aluminium-Foil Sealing Tape to make the joints vapour-tight.
  4. Masking the wall connection area - To protect the wall connection area from moisture, we recommend SELITstop® Moulding Protection Belt.
  5. Installing the flooringLay the flooring in the same orientation as the underlay. Do not place any load on the underlay. If necessary, place the board under your knees/feet to distribute the load.
  6. Finishing the installationRepeat steps 2 – 5 until the entire floor has been installed. Connect the individual panels of the underlay using the easy click® contour. Seal all joints with the Aluminium-Foil Sealing Tape to make them vapour-tight.

 Meets the increased requirements of the EPLF and MMFA (Group 1)
