By Paul Kennington, technical director, Veka UK.
Five years ago, Veka introduced WinDoPlan to integrate structural and thermal calculation directly into window and door specification. The platform enables Veka systems to be configured within defined structural and thermal parameters at design stage. Wind load can be calculated using project-specific location data and building characteristics, allowing suitability to be assessed before quotation, manufacture or installation.
Whole-window U-values are calculated based on actual configuration, distinguishing between frame and centre pane performance to support accurate thermal assessment. Automated validation checks identify oversized or unachievable designs, helping ensure configurations remain within defined performance limits before progressing further.
For fabricators and specifiers, early-stage modelling supports clearer decision-making. Defined performance parameters reduce the likelihood of redesign, support more accurate quotations, and contribute to predictable delivery across projects.
As energy efficiency expectations continue to evolve, including the direction of travel toward the Future Homes Standard, configuration-specific calculation is becoming increasingly important. Assessing wind load and thermal performance based on actual design intent supports greater clarity and consistency from the outset.
WinDoPlan brings together a wide set of features that streamline specification and support day to day fabrication:
- Download Manager offering access to component drawings in PDF, DWG and DXF formats.
- Fully dimensioned cross sectional views to support detailed verification.
- Interactive 3D images for clearer visual understanding of product configurations.
- A dedicated Projects Area with templates, free text notes and fabricator branding options.
- A Free Draw area for representing bespoke shapes such as arched or circular frames.
- Area weighted U-value calculation to support preparation for evolving regulatory requirements such as Future Homes Standard.
- Postbox Support, giving users direct access to Veka’s technical team when guidance is needed.
- Recently introduced, Fastenings Planner to help ensure sufficient fastenings are specified.
WinDoPlan forms part of Veka’s wider technical framework, developed over four decades of operating in the UK market. Modelling capability sits alongside validated testing and structured technical governance.
Veka’s Windows product set is independently verified as conforming to the Code for Construction Product Information (CCPI), ensuring product information is managed accurately.
