Ceiling Insulation
Improve Comfort, Save Energy, and Protect Your Home
Ceiling insulation is one of the most effective ways to create a comfortable, energy-efficient home. By installing the correct insulation in your roof space, you keep the heat out in summer and lock warmth inside during winter. This means lower heating and cooling costs all year round – while enjoying a more stable indoor temperature.
At Cape Ceilings & Drywalling, we supply and install a wide range of ceiling insulation products, all SANS 10400-XA compliant, ensuring your home or business meets South African building standards.
