2 162 Regulations Fire Republic of Ireland Technical Guidance Document B 2006 Northern Ireland Technical Guidance Booklet E 1994 Acoustics E&W Approved Document E (Sound Resistance) and Robust Details Part E is equivalent to: Republic of Ireland Technical Guidance Document E 1997 (Reprint 2005) Northern Ireland Technical Guidance Booklet G Cavity Wall Insulation A range of insulation products are available including partial fill and full fill boards in sizes to suit all cavity widths. Full-Fill Cavity Wall No need for residual cavity. Suitable for mineral wool and some expanded polystyrene insulants. Insulation thickness must be at least 50mm. Wall tie or suitable fixing is essential. Foil faced insulants are not suitable for this application. Partial-Fill Cavity Wall Used where small residual cavity is needed to avoid risk of rain penetration. Residual cavity must be an absolute minimum of 25mm. Suitable for all insulants. Thinner, foil faced insulation boards reduce heat radiance across the cavity and reach required U-Value. Any problems associated with complete cavity fill can be avoided.

The boards are unaffected by the conditions encountered on flat roofs, including wide fluctuations in temperature or repeated freeze/thaw cycles. Roofmate SL-X insulation is intended for use on heavyweight decks with a ballast layer of gravel or concrete slabs. It can also be used in the Roofmate MK system, which will reduce the rain water cooling penalty, thereby minimising the insulation thickness required. Its rotresistance makes it ideal for insulating roof gardens.
