How the stocked flooring system fits together
1. Isolate the perimeter
Use the appropriate 30mm, 50mm or 100mm perimeter strip to prevent the dry floor making a rigid connection to surrounding walls.
2. Level the substrate where required
114173 Dry Levelling Compound is used to form a level full-surface base on suitable uneven substrates. Flooring elements are not laid directly across open joists.
3. Lay, glue and screw
Bond the rebated laps with 106182 Greenline Floor Glue and use 19mm flooring screws for 2E11 or the appropriate 22mm screw for the specified thicker element build-up.
Selected published flooring acoustic test results
| Tested build-up | Reported laboratory result |
|---|---|
| 2E31 direct on the brochure's defined concrete base floor | ΔLw 21dB; reported Rw 61dB for the stated complete construction. |
| 2E11 over 20mm Fermacell dry levelling compound | ΔLw 18dB. |
| 2E22 over 20mm Fermacell dry levelling compound | ΔLw 20dB. |
