Compliance with Building Regulations Part L and Part E
Implementation of the amendments to part E and L of the Building Regulations came into force in 2002. Amongst the new measures it is required that the thermal bridging and fabric insulation be improved (part L) and the resistance to sound reverberation, especially at low frequencies, required (Part E) be increased.
Compliance with the new regulations can easily be achieved using our Hi-Spec range of lintels.
