  • Stone wool angle fillet for flat roof applications The area between horizontal and vertical interfaces can sometimes be the most challenging part of a flat roof to insulate and seal. HARDROCK® Multi-fix Angle Fillets have been specifically designed to create a smooth transition at 90° abutments, for effective flat roof insulation and waterproofing.
  • Consisting of a dense ROCKWOOL insulation slab bonded to a rigid 6mm exterior-grade fibre cement board, this combination of two non-combustible products provides an impact and weather-resistant insulation solution for flat roof upstands and parapet walls.
  • Sound-absorbing trough fillers for perforated steel decks. The underside of an exposed profiled deck is acoustically reflective, which serves to increase reverberant noise in the space below, making for a noisy and echoey acoustic environment. The solution is to install ROCKWOOL Acoustic Infills into the troughs of a perforated deck. This tissue-faced product acts to absorb incident sound, reducing noise build-up, which lowers the reverberation time and creates a quieter acoustic environment.

Choosing the best roof insulation for you

Selecting roof insulation shouldn’t overwhelm you; it’s about finding what suits your needs best. Offering solutions for various roofing applications, including pitched roof, flat roof, inverted roof, and metal roof insulation, there’s a solution for you.

Plus, the type and thickness you choose will depend on several factors, including roof design, building usage, climate, available space, accessibility, and roof type. But let’s break it down even further:

Choosing the right material

We provide a diverse selection of roof insulation materials suitable for different roofing needs:

  • Multi-foil insulation
  • PIR (Polyisocyanurate)
  • XPS (Extruded polystyrene)
  • Phenolic insulation
  • Rock and glass mineral wool slabs, rolls, and boards

Unsure which is right for you? It’s best to speak to our specialists to determine the best material for your building.

Roof Insulation Rolls: These offer flexibility and easy installation, making them the economical choice. Ideal for those aiming to save on labour and materials.

Insulated Roof Panels: While pricier, they provide durability and longevity, resisting sagging and deterioration, making them a solid long-term investment.

When it comes to your roof insulation type, here are some considerations:

Pitched roof insulation

Cold loft insulation is the simplest and most cost-effective option. Insulation is placed over and between wooden joists, above the ceiling of the top floor. Alternatively, a warm loft entails insulation fitted beneath the roof, between and beneath sloping rafters.

Materials like glass wool offer excellent thermal and sound insulation, while roof insulation boards provide rapid installation, albeit with slightly less soundproofing.

Flat roof insulation

The distinction between warm and cold flat roofs lies in the insulation location. In a warm roof, insulation sits on top, keeping the roof structure warm. Conversely, in a cold roof, insulation is between rafters and the roof deck, leaving a cold gap underneath. For optimal thermal performance and easier installation, a warm flat roof is recommended.

Rockwool mineral wool and PIR insulation boards are common choices for insulation for flat roofs.

No matter your project or budget, we’ve got you covered. Need help deciding? Let us assist you in finding the perfect fit for your roof insulation needs.

Frequently asked questions

How much does roof insulation cost?

Well, how big of a roof are we looking at? Plus, what type of roof do you have, and what type of material do you want to use? Long story short, the cost of roof insulation varies depending on a lot of factors, so it’s best to make an enquiry and discover the best solution for your unique needs. Remember, even though it’s an investment to start with, the money-saving benefits in the long-run should pay for itself.
