Insulation for Rainscreen Cladding
U-value CalculatorStart your U-value calculation >
Ventilated façade walls (also known as rainscreen cladding walls) typically provide protection from the elements to tall steel-framed or concrete-framed buildings. Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility can be used in the external walls of relevant buildings over 18 metres in height (England & Wales) or 11 metres in height (Scotland).
The insulation of choice in these types of walls is a stone mineral wool slab installed against the sheathing board prior to the installation of the rainscreen cladding system.
