Taraflex Combisport 28 / AE 28 Systems Installation ... - Gerflor

SUB-BASE
The Sub-Base must be dry, clean, smooth & level BS 8204 SR1 (3mm deviation over 2 metre straight
edge), free of nibs or loose material, and constructed to withstand design loads.
Note:
The performance of the System 28 will be adversely affected if it is installed over an uneven
subfloor. Therefore we cannot guarantee the performance if fitted outside the above
recommendations.
VAPOUR BARRIER
A vapour barrier, such as minimum 1200 gauge polythene sheeting, should be installed over all ground
level slabs and new concrete bases above ground level, Joints shall be lapped a minimum of 150mm,
and should be taped and sealed with waterproof adhesive tape, with edges upturned to the same height
as the plywood overlay board at all perimeter walls.
5 – Positioning Perimeter
PERIMETER EDGE DETAIL
“System 28” sports boards, as in common with other wood based products; attract moisture, resulting in
expansion or contraction when installed in a new building or a building undergoing renovation. We
would recommend for a sports hall up to approx 800 m² that a minimum gap of 20mm is left at all
perimeter and abutments. For sports halls in excess of 800 m² contact Gerflor Technical Department.
The expansion gap is then filled with “System 28” Perimeter Foam (20mm x 50mm) and then trimmed to
finished board level. The Gerflor Taraflex Sport M Plus or Taraflex Surface is then fitted in the normal
manner to within 10mm of the perimeter wall. Skirting/rebound boards should be fitted after the
installation of the floor covering. Any skirting/rebound boards should be wall fixed only 1mm proud of
the surface of the floor.
