In terms of the named “NBS Domestic Specification”, this has been chosen because it has primarily designed with the expectation for use on small domestic projects. Clearly, if anyone thought this content is suitable for one of their simple, small scale, commercial refurbishment projects then they would be welcome to use the service for this.

  1. The right insulation to use as Basement wall insulation is rigid foam insulation. The special rigid insulation board available from Dr. Energy Saver won't absorb moisture or support mold. It can't settle or compress like fiberglass insulation, and it can stop cold air infiltration instead of allowing it to pass through the insulation layer. As a bonus, insulation has an integral radiant barrier that reflects heat for additional comfort and energy savings.
