ISSUE 1 2008 www.xtratherm.com Insulation for Under Floor Heating Systems XT/UF High performance PIR floor insulation board More than insulation.

Under Floor Heating systems have become the heating method of choice for many new build projects over recent years being particularly suited for use when Renewable Energies such as Ground Source Heat Pumps are integrated into a design. Xtratherm XT/UF Under Floor Insulation will achieved best performance U-value standards with the minimum thickness of materials. Below floor slab Xtratherm XT/UF provides the most efficient means of insulating a floor to the new 2006 standards. Typical floors in the UK have a Perimeter/Area ratio of between 0.4 and 0.7 - 75mm of Xtratherm will achieve a U-value...

Thin-R The floor performance is determined by working out the floor Perimeter to Area ratio, the perfimeter being the total length of the floor perimeter inside the total outer wall of the property and the area is ground floor area only. The above calculations are indicative only, for specific calculations contact technical support. Xtratherm Under Floor Insulation consists of a rigid Polyisocyanurate (Polyiso) core and aluminium gas tight facings both sides, with a thermal conductivity of 0.023. The (l) lambda values and (R) resistance values stated are in accordance with the 90/90 principles...
