Building Regulations

All buildings must comply with the building regulations which only set the minimum standard for buildings. These regulations must be read in conjunction with development plans that may in fact have a higher standard of thermal insulation than that set in the building regulations.

We recommend that you build using thermal performance criteria that surpasses any current or upcoming performance levels set by building regulations and in doing so, future proof your building.
