Thrutone ENDURANCE is the highest density slate in the Irish market which means it offers the best resistance to Ireland’s famously volatile weather, with the extra fibres giving the product its highest flexural strength and a specialist silicone paint providing a unique water repellence.

Thrutone ENDURANCE is accredited to the highest environmental standard BES 6001 and Tegral is the only Irish manufactured roofing product to achieve this rating. Thrutone ENDURANCE is an evolution of Tegral’s best selling ThrutonePlus slate , but with a series of major product enhancements achieved at a cost of over €2m. Following years of intensive product development and rigorous testing*, Thrutone ENDURANCE can now claim the following product benefits:


  • Highest density slate on Irish market which means the best frost-resistance
  • Extra fibres to give the highest flexural strength
  • Unique silicone paint to provide the best water-repellence
  • Improved paint application & rigorous testing to ensure the highest quality standards
  • BES 6001 Accredited – environmentally sustainable


As well as being “Irish made for Irish weather’ and an elegant and beautifully designed product to dress any roof, Tegral Thrutone ENDURANCE comes with a 20 year colour and 30 year structural guarantee, giving roofers and home owners the ultimate peace of mind.

Speaking at the launch of Thrutone ENDURANCE, Paddy Kelly, Managing Director of Tegral said, “ThrutonePlus has been our best selling slate product for decades, and we’ve invested over €2m to enhance it with some transformational improvements to make it stronger and more durable. The end result is Thrutone ENDURANCE, and we’re so excited to finally be in a position to launch this game-changing new product to the market. Feedback so far from roofing contractors and merchants is extremely positive, and pre-orders have been very encouraging. Between product improvements and delivery to market, we’ve invested over €2m in developing  Thrutone ENDURANCE; it represents our biggest NPD innovation in over 10 years.”
