Floor preparation

Stage 2

EXPOSED EDGES:

Must have temporary framework installed to all exposed edges.

INSULATION:

Ensure that all high/low points are removed from the sub-base and that insulation boards are laid flat. Insulation boards should be tightly butt jointed with staggered joints.

MEMBRANE:

Installing polythene will separate the insulation to the screed floor using 500 guage or similar, joined with tape. Ensuring that all air pockets are removed and are free from punctures and creases. Isolation strip should be fixed to wall/floor junctions and around any columns, pipework etc.
