Pitched Roof Insulation Eco-Versal

Pitched roof insulation is the key to maintaining a warm, energy-efficient home or workspace. Using specialised insulating material to seal off one of the most significant areas of possible heat loss helps transform roof spaces into cosy, usable environments.

What is insulation for pitched roofs?

It is a thermal layer fitted within the roof structure. Depending on the project, the insulating material is fitted between rafters, above rafters, or below them. Between-rafter systems are the most common in UK homes because they balance excellent performance with ease of installation.

These insulation systems are designed to contain temperature fluctuations and control moisture. They create a thermal barrier and protect against cold draughts and excessive heat.

What is pitched roof insulation used for?

Insulation for pitched roofs contributes to:

• Thermal protection for loft conversions and attic refurbishments.
• Boosting thermal stability in new-build pitched roof systems.
• Delivering energy upgrades in older properties.
• Reducing noise in living spaces directly under the roof.

Types of suitable insulation for pitched roofs

We have several effective materials that work well for pitched roofs, including:

• PIR insulation panels: Lightweight and rigid. Commonly used between or under rafters for excellent thermal resistance.
• Phenolic insulation foam panels: Slim yet efficient. Ideal for space-constrained areas.
• Mineral wool rolls or slabs: Great for acoustic control, flexibility, and fire resistance. They are commonly installed between rafters. Perfect for lofts.
• Multifoil insulation: Reflective layers that help manage radiant heat. Often combined with other insulation types.

A popular choice among professionals is Kingspan Kooltherm K107 Pitched Roof Board. It offers outstanding thermal efficiency and moisture resistance in a slim build and is among the most reliable insulating products in the UK, depending on the application.
