Africa Thermal Insulations (ATI) specialises in thermal insulation products that meet the recently updated building regulations, as required for proof of compliance and occupancy certificates.  In the past, the decision on whether to include roofing insulation or not was most often left to the architect or owner of a building. It was an optional choice and insulation was often excluded, viewed as an unnecessary expense. However, with the recently legislated new building regulations, it is now essential for builders and roofing specialists to highlight to customers the need for effective insulation – not only for the benefit of reduced energy bills but also to meet specific industry standards and obtain the required compliance and occupancy certificates.

The newly legislated SANS 10400-XA: 2011 and SANS 204: 2008 introduce the requirement for proof of compliance with the standards set out for energy efficiency in buildings. This means that architects and building developers need to ensure that new buildings and building refurbishments are designed to meet the prescribed energy efficiency standards; that a building’s performance in terms of energy usage is calculated and documented; and that the building is built to perform accordingly.  Thermal insulation materials – for roofs, walls and floors – constitute a key element in building to achieve the required thermal resistance values (R-values) as set out in SANS 204.

At the 4th annual convention of the GBCSA (Green Building Council of South Africa) held in Cape Town last year, several residential green building retrofit projects were announced by GBCSA CEO Brian Wilkinson, including a British High Commission-sponsored ‘green street’ retrofit in KwaZulu-Natal, coinciding with Durban’s hosting of COP17.  Energy performance and the use of the most appropriate green building materials are key to sustainable building – in housing as in other sectors.

keyboard_arrow_upEco-friendly insulation for Castle of Good Hope
keyboard_arrow_downEco-friendly insulation for Castle of Good Hope

Constructed originally between 1666 and 1679, the Castle of Good Hope in Cape Town is one of South Africa's oldest surviving buildings and it is still in use. It is the seat of the military in the city and houses the Castle Military Museum and the William Fehr Collection of Cape Town’s Iziko Museums. Military personnel, museum administrators and tourism support staff are at work within its four-metre wide walls.  However, inside the massive structure of the outer walls, there has been for many years a problem with the working environment. Despite the high thermal mass of the structure, the dark coloured roofing material has a high thermal conductivity and low insulating properties. This means the office space heats up through summer and becomes chilly in winter, once the inside walls have cooled to the ambient temperature.

keyboard_arrow_downInsulation to match new energy efficiency standards

The National Building Regulations have been updated to include Part X, which addresses environmental sustainability, and Part XA, which establishes requirements for energy efficiency in new buildings and renovations. The application of this new legislation, which came into effect in November 2011, is good news for the environment and will help individuals, businesses and the country as a whole to save electricity.  In home building, insulation is often considered a luxury and is overlooked, yet its primary purpose is to save energy and improve the home’s comfort. To insulate the ceiling and geyser system properly in a typical home costs less than 1% of the total per square-metre building costs and effective insulation is one of the few building materials that will, in effect, go on saving money over the lifespan of the home.

abeproof thermo-shield, a new heat-shielding and waterproofing product from a.b.e. Construction Chemicals, was used recently to waterproof a large roof area of the Sunbel building in Voortrekker Road, Bellville, Cape Town.  abeproof thermo-shield is a water-based waterproofing membrane which incorporates advanced insulation technology. It contains fine spherical particles that minimise the surface temperature on roofs and walls by re-emitting most of the radiant heat energy away from the building before it can reach the interior. As a result, internal temperatures are kept low and the energy costs required to cool the building are reduced.

Alububble radiant barrier insulation, manufactured by Africa Thermal Insulations (ATI) has been used for many years mainly in industrial applications. Over recent years it has gained popularity in domestic applications as well. Although it is clear that the product works, there have been no recognised test methods that measure the difference radiant barriers make to internal temperatures when installed. ATI therefore decided to conduct a test case study using thermal imaging.  First, in an uninsulated house, it recorded thermal images and temperatures at different points outside and inside the building. These temperatures showed the heat flow into the house. A retrofit installation of Alububble was then completed in the house and thermal images and temperatures were recorded again.  The outside temperature on both days was recorded at 30°C but the difference in the internal temperature, once the Alububble radiant barrier had been installed, was notable. The diagram illustrates the temperature readings on both the insulated and uninsulated house.
