Our loft insulation solutions provide the most cost effective insulation solution with regards to the ratio of cost to energy saved as insulation thickness is largely unrestricted, allowing very high levels of thermal performance.
Whilst regulations in South Africa require one layer of the appropriate thickness, better performance (eg. energy saving) is achieved with 2 layers. To achieve this, a base layer of 100mm is installed between the joists, and the second layer is cross-laid on top of the base layer to prevent thermal bridging.
WHY MINERAL WOOL?
Insulating at ceiling level with mineral wool provides the most cost effective solution to save energy and improve acoustic performance.
Mineral wool reduces heat gain during the day and residual heat loss at night.
At Knauf Insulation, we are committed to helping our customers meet the increasing demand for energy efficiency. Browse our other application pages to find out more.
