At Triflex, we provide tapered insulation schemes as part of our liquid roofing systems. Every solution is created to order through our Triflex bespoke project specification proposal process, ensuring the perfect balance of drainage performance, thermal efficiency, and long-term waterproofing durability for your warm flat roof.
Our tapered insulation roof system schemes are fully compliant with BS 6229:2025, and BS5250 as well as designed to your exacting U-value requirements. We ensure that our tapered insulation solutions are relevant to all building regulations in your region, providing performance and reliability you can trust.
Why choose tapered insulation in warm roof builds?
Optimal drainage & waterproofing protection
Our tapered insulation schemes are designed to achieve a design fall of 1:40 to ensure a finished fall of at least 1:80, directing water efficiently to outlets and preventing ponding. The reinforced waterproofing of our PMMA liquid roofing systems deliver outstanding waterproofing performance in a single process, rapidly installed for a long-term service life.
Energy Conservation
Whatever your exacting thermal requirements, we ensure that the U- values meet both relevant regional building regulation and your project requirements. From thermal calculations to condensation risk analysis, we take a considered view. With experience in energy efficiency and regulations in England, Scotland, Wales, Ireland and the channel islands, our expertise is available to all specifiers across the UK and Ireland.
Complete service from design to support
From initial roof survey to detailed CAD layout drawings, thermal calculations, and installation guidance, our Triflex bespoke project specification proposal process ensures your tapered insulation is compliant, efficient, and future-proof.
Key advantages of Triflex tapered insulation for liquid roofing systems
- Integrated drainage falls to meet BS 6229:2025 requirements
- Thermal continuity to meet Building Regulation U-value limits
- Bespoke design for each project, ensuring accuracy and minimal waste
- Seamless integration with Triflex cold-applied liquid roofing systems for a fully waterproof solution
- Easily refurbished with reapplication of Triflex liquid systems in the future
When to specify Triflex tapered insulation
Our tapered insulation schemes are ideal for:
1. Refurbishment projects where existing falls are inadequate
2. New-build warm flat roof projects requiring integrated drainage
3. Projects requiring precise U-value compliance and condensation control
4. Roofs with complex layouts, upstands, and multiple drainage and outlet points

Single layer solution
With single layer solutions that are factory bonded in optimum conditions, we reduce on-site adjustments, minimise waste, and speed up installation.
Superior Time and Cost Efficiency
Because the drainage falls are built into the insulation layer, installation is quicker and simpler than multi-layer build-ups, cutting labour time and associated costs.
