    The Air-Cell product will be well supported by the wire ties in the wall and restrained by the spacers so sagging to this extreme is unlikely. However, if this was to occur assessments show that the effect on the Total R-value performance could be approx. 15% reduction, but the Total R-value achieved would be still likely to meet that required by the BCA.

  • But over time I'm guessing that the aircell would eventually sag up against the skins of the brick anyway wouldn't they? Would this affect the effeiciency as I userstand that it is reliant on the airspace.

    The Spacer Biscuits are required to position the Air-Cell correctly, and to prevent it from being pushed against the brick leaf because if this were to happen it would be difficult to re-position.

  • Are the spacers required? A builder with any skill could centre the insulation.
