EJOT: Fixing innovation streamlines installation of flat roofs with tapered insulation

  • 22 Mar 2021

Roofing and cladding fastening systems specialist EJOT UK has developed a new mechanical fastener solution to help installers save time and money when installing flat roofing with tapered insulation.

The JBS-R/EcoTek combination brings together a high performing concrete screw (JBS-R 7.5) with a high-quality telescopic tubewasher (EcoTek) to provide a fixing solution that is adjustable to fit the required depth of insulation.

It is universally suitable too, providing a solution for mineral fibre, EPS, XPS and PIR tapered insulation.

As the illustration below shows, this makes the fastener suitable for any insulation depth of between 70mm and 590mm, using fewer fastener/washer combinations than current mechanical fixing approaches.


This can easily reduce fastener use for a slope insulation of 120 to 260 millimetres by as much as 25%, subject to the application, a site survey and pull out test. 

Installation is easy, as only one embedment depth is needed whatever the insulation thickness and adjustability is achieved thanks to the innovative way that the EcoTek tubewasher is driven into place using a custom tool with the fastener already in place.

And where the insulation is especially deep, installers can simply use EJOT’s flanged A-cone and extension – this helps to eliminate the awkwardness of drilling deep using standard SDS drills. 

‘Huge potential to make a difference for installers’

Kevin Rackley, Product Manager for Flat Roofing Fastener Systems at EJOT UK, says: “Cut to falls insulation is used in around a third of all the flat roofs installed in the UK today so it is important that we innovate and find ways to make this approach as easy and cost-effective as possible.

“This is why the JBS-R/EcoTek fastening system offers huge potential to make a difference for installers. Given the need for only one set embedment, using JBS-R/EcoTek means installers don’t need to think about the usual variety of product combinations on site – the job can be done easier and quicker with an all-round better result. 

“And using this new EJOT product combination also simplifies ordering and stockholding for contractors with no need to source a variety of different concrete screws and stress plates.”

Long term performance is assured when using the JBS-R/EcoTek fastening system, given the quality materials used to manufacture both fastener elements.

The JBS-R concrete screw manufactured from case hardened steel and the EcoTek tubewasher is formed from high grade plastic to provide a lasting solution.
