Government regulations will be introduced in 2011 specifying minimum insulation levels for all new homes and buildings built in South Africa. Small alterations or renovations to existing buildings requiring a building permit may also have to comply with the regulations.

SANS 10400-A The application of the National Building Regulations Part A: General principles and requirements establishes general requirements for satisfying the National Building Regulations issued in terms of the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977).
Building plans submitted to the local authorities shall comply with the requirements of Form 1, Schedule A and B and Form 2 in order to be approved.

The selection and specification of the thermal insulation material should comply with the following:

the relevant South African National Standards published by the SABS and applicable to the product; conform to the requirements of the South African National Building Regulations; is appropriate for the intended use and application for the particular occupancy or building classification in accordance with SANS 10400 Part A General principles and requirements; comply with the fire safety requirements of SANS 10400 Part T Fire Protection and tested in accordance with the requirements of SANS 428 Fire performance classification of thermal insulated building envelope systems requirements. thermal performance specifications comply with the recommended R-value for the relevant climatic zones in accordance with SANS 10400-XA Energy usage in buildings. Valid test reports

Professionals will no longer be able to disregard the importance of roof insulation as far as the new energy efficiency and fire standards are concerned by settling for “something similar but cheaper”.
Contractors often compromise the Code for Safety to Life from Fire in Buildings and Structures, known as the Life Safety Code, by proposing insulation products similar to what has been specified by professionals, but cheaper, to cut building cost, with total disregard to fire safety. The Consumer Protection Act shall eliminate such practices in future.
Careful consideration should therefore be given to the type of roof insulation materials at specification stage and to comply with the required new performance criteria according to the new classification system in order to avoid any litigation.
