Choosing the best tapered roof insulation is important for any project

Our tapered roof insulation eliminates the need for a structural fall which is great for both specifiers and installers.

Tapered roof insulation is generally a cheaper, quicker and lighter way of creating a fall in your roof. Insulation boards are fitted with a dry installation process and can be used with partially bonded torch applied multi-layer bituminous waterproofing, mechanically fixed waterproofing and bonded waterproofing systems.

Perfectly tailored to your project, we can provide a tapered design service to identify the most cost-effective solution to your insulation requirements and specification for rainwater run-off. 

Our tapered roof insulation benefits:
  • The dry installation process is a quicker, lighter and cost effective way of creating a fall in your roof compared with wet approaches such as screed to fall which can take many months to dry.
