The saying goes that every second counts. And Knauf Insulation know that conducting hundreds of U-value calculations over the course of a year means that the seconds, minutes and hours quickly add up.

They also know that whether you're designing your next project, helping your customers in branch or just researching insulation U-values and properties, time is of the essence.

With this in mind, Knauf Insulation have launched a free online U-value calculator that will save you time. And because it has been developed from the ground up, it is quick and easy to use.

Their U-value calculator allows users to choose from a range of typical build-ups, or enter the specifications for their own project. All calculations are performed in line with the requirements of Approved Document L.

Once the U-value has been calculated, the tool recommends the most suitable Knauf Insulation Glass or Rock Mineral Wool product for the chosen application. Users are then able to download detailed calculations, BIM files and product data, or send a copy of their calculation to their email address.

This is just the start – over time they will expand the range of typical build-ups to incorporate the calculations you do most using the direct input tool.

As well as the new online U-value calculator, the Knauf Insulation Technical Support Team can provide 3D U-value calculations for more complex projects such as rainscreen façades over the phone or via email.

Their new U-value calculator is free to use and can be accessed here. Once you’ve completed your calculation, don’t forget to leave your feedback, to help them improve user experience further.
