Roof insulation

Roof insulation is the process of adding a thermal barrier to the roof structure to reduce heat transfer between the inside of a building and the outside environment. It helps keep indoor spaces cooler in hot weather and warmer in cold weather, while also lowering energy bills.

Common Types of Roof Insulation:

1. Fiberglass Batt Insulation

   • Affordable and widely used.

   • Easy to install between rafters.

   • Requires proper sealing to avoid gaps.

2. Spray Foam Insulation

   • Expands to fill gaps and cracks.

   • Provides excellent air sealing.

   • More expensive but very energy efficient.

3. Rigid Foam Boards (XPS, EPS, Polyiso)

   • High insulation value per inch.

   • Suitable for flat and sloped roofs.

   • Good for both above and below the roof deck.

4. Reflective or Radiant Barriers

   • Made of aluminum foil sheets.

   • Reflect heat rather than absorb it.

   • Effective in hot climates.

5. Mineral Wool (Rockwool/Slag wool)

   • Fire-resistant and soundproof.

   • Good thermal properties.

   • Heavier than fiberglass.

Benefits of Roof Insulation:

• Reduces energy costs by 20–40%.

• Improves comfort by maintaining indoor temperatures.

• Reduces condensation and moisture buildup.

• Increases building lifespan by protecting the roof structure.

• Adds acoustic insulation against outside noise.
