WHATEVER THE ISSUE, WHEREVER THE APPLICATION, GRADIENT HAS THE TAPERED INSULATION TO SUIT YOUR ROOF

By James Wilkinson, Design Team Manager at Gradient

In basic terms, tapered insulation is an ideal solution for directing water run-off whilst ensuring the roof achieves regulation levels of thermal performance. It’s not an outcome that happens by accident; it requires good planning, installation and a high-quality system that is designed to meet the specific demands of the application.

Gradient, with our bespoke delivery of flat and tapered roof solutions, works closely with clients to navigate each element of the insulation process to ensure a project’s success. From specification and design through to the manufacturing stage and beyond, our turnkey service provision gives clients peace of mind that the tapered insulation system delivered will keep their roof watertight and warm for years to come.

We have a wide range of tapered insulation solutions which can be tailored to suit a variety of applications regardless of size, complexity or profile. They include:

Powerdeck® F: This BBA-certified product is faced with a mineral-coated glass fleece. Its variable lambda value (between 0.024 and 0.026 W/mK) is based on the board’s thickness. Suitable for a multitude of waterproofing systems including adhered single-ply membranes, poured and rolled felt applications, and mastic asphalt; Powerdeck® boards benefit from high compressive strength and dimensional stability.

Powerdeck® U: Has the same variable lambda value as Powerdeck® F. Its bituminous facia makes it the ideal board for torch-on waterproofing systems. Powerdeck® U is also BBA-certified.

Eurothane® Eurodeck: Compatible with mechanically-fixed, single-ply waterproofing systems, this excellent thermal insulation board offers a consistent lambda value (0.022 W/mK). BBA certified, Eurothane® Eurodeck ensures a superbly-flat surface finish in new-build and refurbishment projects.

Rockwool Hardrock Multi-Fix (DD): A BBA-certified stone wool insulation board, which has a mineral-coated white fleece, this is a true allrounder when it comes to compatibility. Single-ply, EPDM, liquid membranes, green roof systems; Rockwool Hardrock Multi-Fix is the ideal accompaniment to a wide range of adhered and mechanically-fixed waterproofing systems. Its dense composition not only reduces the transfer of airborne noise, it absorbs vibration and sound pollution caused by direct impacts such as heavy rain.

In addition to our core solutions, we have developed a variety of specialist products for non-standard applications. Topcover, for instance, provides added protection for PIR boards in areas of excessive traffic and high loadings. The ultrathin board, which contains a high compressive strength, is ideal in flat roof applications that experience intense thermal cycling between cold winter temperatures and extremely hot summers.

We’ve also a range of pre-bonded hybrid systems, such as a PIR/mineral wool panel, which maintains excellent thermal performance whilst offering superb acoustic properties. Again, this is particularly effective for absorbing the sound rainfall on a flat roof, an issue which is addressed in BB93 guidance for performance standards for the acoustics of school buildings.

Each of our specialist systems is imbued with the quality afforded by Gradient’s regular production methods; a process, which coupled with our teams’ technical expertise, allows us to create a bespoke tapered insulation solution that will long-term protect your roof and building, as well as safeguard against costly remedial works incurred by less-effective insulation systems. That’s why, when it comes to protecting your building’s most protective element, it pays to engage with a specialist such as Gradient.
