Roof & Ceiling Insulation — Products & Installation

Upgrade your home with high-performing roof insulation. We supply and install ceiling insulation products and materials—glasswool (Aerolite, Knauf, Factorylite), polyester (Fabufill, Isotherm), polystyrene boards (Summit XPS, Isoboard), and radiant barriers (Sisalation, Alububble).

Proper insulation in roof cavities delivers an insulated roof that stays cooler in summer and warmer in winter while cutting energy use. We provide roofing insulation in Johannesburg, Centurion, and Pretoria.

1. Quick Picks For Insulating Ceilings (inside the home)

Aerolite / Knauf (glasswool): Best performance-per-rand for insulated ceilings; choose the recommended thickness to hit your target R-value.

Fabufill / Isotherm (polyester): Soft, low-itch and DIY-friendly insulation for ceilings; typically needs more thickness than glasswool to match thermal performance.

Isoboard / Summit XPS (ceiling boards): Smooth ceiling finish plus a thermal break below rafters; ideal for modern interiors and retrofits.

2. Quick Picks For Insulating Roofs (between or below rafters)

Glasswool (Aerolite / Knauf): Highest R-value between rafters—reliable insulation for roofs in both hot and cold seasons.

Ceiling boards (Isoboard / Summit XPS): Installed below rafters to reduce thermal bridging and improve comfort; pairs with a neat internal finish.

Polyester (Fabufill / Isotherm): Installer-friendly option for insulating roofs; but lower R-values, densities, fire ratings, and acoustic performance.

Roof Insulation Services in Johannesburg • Centurion • Pretoria

Whether you’re in Johannesburg, Centurion, or Pretoria, properly insulating your roof is one of the smartest home upgrades you can make. In Gauteng’s climate, summers bring intense heat that radiates straight through uninsulated roofs, while winters allow warmth to escape just as quickly. Our local installation teams supply and fit high-performance roof-insulation products that keep your home comfortable all year round — reducing electricity costs, improving energy efficiency, and meeting SANS 10400-XA building standards.
