Why Choose Aerolite Insulation

What Affects Aerolite Cost?

Thickness & R-Value: Higher thickness = greater thermal resistance = higher cost per roll and per m².
Coverage Area: Roll coverage will vary; larger rooms or complex roof shapes may increase cost.
Installation Access: Homes with tight trusses, many down-lights or difficult roof access may attract higher labour costs.
Region & Climate Zone: In cooler climate zones (e.g., Johannesburg or Pretoria) thicker Aerolite is recommended, which may affect total cost.

Aerolite Insulation for Different Climates

For coastal Durban or mild-climate areas, the 100mm roll often provides the right balance of cost and performance.
In Gauteng’s mixed-climate zones (Johannesburg, Pretoria, Centurion) we recommend the 135mm roll for maximum year-round comfort.
For homes simply topping-up older insulation, the 50mm roll is a cost-effective option.
