Insulation is the most effective way to improve the energy efficiency of a home or a building.
Insulation of the building envelope helps keep heat in during the winter and out in summer to improve comfort and save energy.
We design the roof insulation systems to meet SANS 10400-XA regulatory requirements.
We do R-value calculations and provide advice on the optimal use of roof insulation materials.
The introduction of new Energy usage regulations (SANS 10400-XA) and Energy efficiency codes (SANS 204) has profound implications on the design philosophy of roofs.
The thermal insulation as well as the structural and aesthetical requirements of a roof are designed interactively.
Insulation could add additional benefits such as acoustics and waterproofing.
