Tapered Insulation
Gradient applies its technical expertise to combine insulation materials effectively, optimising overall system performance. This is particularly important for tapered insulation solutions, where existing roof falls may need to be reconfigured or reversed to improve drainage efficiency.
Gradient's Tapered Solutions - Designed Around Your Project
Gradient's tapered roofing systems are manufactured to the exact requirements of each individual project, meaning no two schemes are ever the same. Drawing on over 35 years of expertise, Gradient works with an extensive range of high-performance materials - including PIR, cork board, and hard mineral wool - to create bespoke single-layer solutions that optimise both thermal performance and drainage in one efficient build-up. Every system is produced to ISO 9001 standards with full traceability, and manufactured off-site to the finest tolerances, so boards arrive on site ready to lay with minimal cutting, waste, or delays. Whether you're working with a built-up felt system, single-ply membrane, liquid roofing, or mastic asphalt, Gradient has a tapered solution that fits seamlessly into your specification.
Expert Design Support, From First Brief to Final Board
Choosing Gradient means far more than selecting a product — it means partnering with a dedicated team of technical designers and roofing specialists who are with you at every stage of the project. From the initial consultation and drainage analysis through to full system design, manufacture, and delivery, giving specifiers, contractors, and clients a single, reliable point of contact.
The team's depth of knowledge means complex roof geometries, challenging existing falls, and demanding performance targets are all handled with precision and confidence. Submit a project request and Gradient's designers will get to work on a tailored scheme.
The Benefits of Tapered PIR Insulation
Bespoke Designed Drainage
Gradient’s design team work closely with customers to advise, create and manufacture bespoke single-layer insulation solutions. These tailored systems ensure compliance with minimum fall requirements across a wide range of roof applications
Thermal Performance
PIR insulation boasts an impressive thermal conductivity (lambda value) as low as 0.022 W/mK, making it one of the most efficient insulation materials available. This performance allows for thinner insulation layers while still meeting stringent energy performance targets.
Cost Reductions
By combining insulation and roof falls into one single-layered system, tapered PIR significantly reduces material and labour costs.
Structural Load
Compared to traditional methods such as concrete screed, tapered PIR insulation is significantly lighter. This makes it an excellent choice for both new construction and retrofit projects where reducing structural load is important.
Installation Performance
Unlike screeds which needs time to cure, tapered PIR insulation can be installed immediately. This significantly reduces project timelines and eliminates the need for additional subcontractors.
