Pitched Roof

The pitched roof or attic area of a building can be insulated in many ways. Based on local building traditions, requirements, and regulations in combination with the usage of the loft, ROCKWOOL solutions can provide you with the right solution for new-build properties as well as renovations.

Effective pitched roof insulation offers additional thermal comfort, sound protection, and exceptional fire resistance, making it ideal for residential and commercial properties.

Our products are made from premium-quality stone wool, with solutions available for pitched roof insulation below, between, and over rafters, as well as insulation that is placed under the roof. We offer high-performance systems and solutions for homes and businesses.

Why do we need pitched roof insulation?

In tropical climates, a substantial amount of heat is gained or lost through the roof of an uninsulated home.

As heat penetrates the building - potentially raising temperatures to uncomfortable levels. Poor insulation can be costly for property owners and tenants, as spending on cool residential and commercial buildings can be expensive.

To avoid costs and improve living conditions, insulating a pitched roof is among the most popular construction methods of today. Effective insulation can not only help enhance comfort but help reduce air-conditioning costs by up to 40%.

With insulation installed below, above, and between the rafters of a pitched roof, it enhances the aesthetic and water tightness of the roof as well as maximizes the weather resistance of your home.

As noise pollution continues to become a major problem in towns and cities1, properly insulated pitched roofs can also help to create a peaceful living environment.

Our products help to:

  • Conserve energy – and reduce bills
  • Reduce noise pollution
  • Prevent heat gain
  • Provide fire protection

With ROCKWOOL pitched roof insulation, your building is protected for its lifetime.

Calculator and savings

Pitched roof insulation is an affordable and energy-efficient solution for your project or refurbishment. Effective roof insulation can prevent heat from entering or cool air from escaping your roof space, helping to reduce energy bills substantially.

When working out how many ft² you will require, whether you use rolls or slabs as your insulation material, we can match the thickness of the insulation to almost any specification – depending on your needs.

Use our ROCKWOOL U-value calculator to determine the thermal performance of the building's roofs and possible cost savings. For more details on the technical specification, visit our ROCKSPEC Specification Toolkit.

By installing insulation in the pitched roof area with ROCKWOOL insulation, you not only create a thermal barrier, but also increase the acoustic and fire performance of the construction. You also enable the use of the attic area as a living space – such as a game-room for the kids, an extra bedroom, or even a bathroom for your convenience.
