The development consisted of a 19th century stone barn combined with two new build properties. The walls of the existing property were made of solid stone and required a significant insulation improvement to bring them up to standard.
WALLTITE® high density spray foam insulation was applied to the interior surface of the walls to achieve both the U-value and airtightness requirements. The new buildings consisted of a 200mm clear cavity between two leaves of block, so we installed WALLTITE® grade foam to achieve an airtight, homogeneous layer with a U-value of 0.12 W/m2k. The final airtightness test recorded a result of 1 m3/m2/hr.@ 50 Pa.
