INSTALLATION
- Installation of isocheck should not commence until roof, window glazing and wet trades are completed and the structure is watertight.
- Floor should be a level screed / concrete with a smooth surface, or an in-situ concrete base. The floors should be level, sufficiently dry and swept clean.
- Apply Isocheck Acoustic Angled Flanking Band on the edges of the Isocheck boards just before they are pushed against the perimeter walls to isolate the board from the wall.
- Board fitting should begin at the furthest point from the entrance and marked out so as not to finish with any panels less than 200mm wide.
- The decking must be laid in broken bond pattern, with all joints glued and staggered.
- No Mechanical fixings should be used.
- Isocheck adhesive is applied to both the top of the tongue and the bottom of the groove on each side of each joint.
- The boards are then pushed tightly together. Surplus adhesive should be wiped away from the surface with a damp cloth.
