Builders and specifiers who use an online tool to calculate the U-values of their projects can look forward to an evolution of its capabilities very soon
The Actis U-value simulator, which for the past 13 years has been enabling specifiers to calculate the thermal efficiency of every element of a project to ensure it meets Building Regulations, is poised to gain some new features.
The simulator, which simplifies the process of juggling insulation thickness and membrane requirements, helps architects and contractors choose the right combination of insulation materials.
It enables users to try out different combinations of Actis’ flagship honeycomb-structured
Hybris insulation, in various thicknesses, along with its insulating vapour control layers and insulating breather membranes.
Its second iteration, which was launched five years ago, added an invaluable feature for contractors working on roof refurbs – an option to select 400mm centres in addition to the default 600mm setting.
And the next phase of its development, being carried out by the company’s research and
development team at its headquarters in south-west France, will add further user-friendly features, ensuring it continues to be both versatile and easy to use.
The Actis U-value simulator, which enables users to try out different combinations of Actis’ flagship honeycomb-structured Hybris insulation, is being updated with new features behind the scenes
Actis UK and Ireland sales director Mark Cooper explained: “The simulator has helped
thousands of builders choose the right products for their projects since its launch in 2013.
“We updated it a few years ago because it was quite mathematically tricky to work out
the U-value of a roof in an older building as they generally have 400mm centres, rather
than the 600mm centres which are normal with new builds.
“So that was a game changer for builders refurbishing properties, who, since 2021, have had the same experience as those working on brand new developments.
The simulator offers users the chance to play around with a mix-and-match range of insulation products and membranes in pitched roofs, ceilings, timber frame and masonry walls to see how the different combinations affect the project’s thermal efficiency. It produces an estimate in seconds.
The findings can be saved as a pdf which also includes a cross section of the build-up showing exactly which layers are used, where air cavities are maintained and which rafter sizes are required.
The results can also be emailed to one of the technical team at Actis, who can use the figures to prepare a report to be included in a planning application.
