Eurocell has partnered with Windowmaker to support the development of a new U-value and G-value calculation solution designed to help fabricators prepare for the Future Homes Standard and more detailed new-build compliance requirements.
Integrated into Windowmaker’s existing compliance and quoting software, the solution gives fabricators access to verified Eurocell thermal-performance data within their established workflows.
Supporting more detailed performance calculations
The move to the Home Energy Model is expected to increase demand for product-specific performance information. Rather than relying on a single calculation across multiple window configurations, fabricators will increasingly need to provide individual U-value and G-value calculations for each frame specification.
To support this change, Eurocell has worked with Windowmaker for more than two years to integrate over 10,000 validated data points covering its window and door systems.
As a product configuration changes, the software automatically recalculates:
• U-values
• G-values
• Frame factors
This helps fabricators produce accurate performance information more efficiently, reducing manual calculations and the administrative burden associated with compliance and certification.
Compliance integrated into existing workflows
Because the Eurocell data is embedded directly within Windowmaker, calculations can form part of the normal design, estimating and quotation process. This enables fabricators to assess performance as products are configured rather than completing a separate calculation exercise later.
Gary Doxey, Head of Commercial Operations & Technical Sales at Eurocell, said:
“The Future Homes Standard will significantly change how window and door performance is evidenced, particularly as compliance becomes more granular and product-specific.
“By investing more than two years in developing and validating our technical data and integrating it into Windowmaker’s platform, we can help fabricators work within familiar systems while preparing for evolving requirements.”
Remi Gruszka, Head of Sales UK & Europe at Windowmaker, added:
“We’ve worked closely with Eurocell to integrate verified performance data into our platform, helping fabricators generate accurate calculations quickly and consistently within their existing workflows.”
The development forms part of Eurocell’s wider commitment to helping fabricators, housebuilders and specifiers respond to changing Building Regulations through accurate product data, practical technical support and digital specification tools.
