Pack Guide

Government Building Regulations recommend loft insulation is installed to a depth of 270mm. Typically only 100mm is installed (the depth of most typical joists).

Simply combine packs as per the chart below to achieve the required thickness:

INSULATION THICKNESS
Between Joists		Over Joists		Total Thickness	U-Value W/m2K	Meets Regulations
100mm	+	170mm	=	270mm	0.16	Yes

*U-Value (W/m²K): The measure of the rate of heat loss (thermal transmittance) from a building component.
