The IHBC has submitted its response to the consultation on the last of three linked consultations of the Welsh Building Regulations, focussed on the energy efficiency and ventilation standards.
The IHBC writes:
‘The U-values of existing old stone walls, roof or floors is difficult to determine due to difficulties with establishing the exact form of construction and thermal properties of the materials used. This is particularly relevant to traditional buildings with solid wall construction….’
… solid wall construction of any appreciable thickness also acts as a thermal store, retaining heat…
‘… Account should be taken of the fact that solid wall construction of any appreciable thickness also acts as a thermal store, retaining heat provided a low level of heat is constantly maintained. The default values suggest that the U-Values of solid masonry walls are worse than they are in reality on most occasions leading to the requirement to insulate the walls. This will not improve the insulation values of the walls by the target amount since the walls are already performing better than the initial reading indicates…’
The Consultations Panel
The IHBC constantly monitors Government Departments and other national and regional organisations for relevant proposed changes to legislation, policy and guidance. The Consultations Panel formulates responses to these documents on behalf of the IHBC.
The IHBC may not necessarily comment on all these consultations, but we are glad to hear opinions on them from both members and non-members.
