CAD Designs and Calculations
Expert CAD design and calculation services for your building envelope.
SOPREMA provides a comprehensive, seamless experience for your entire building envelope needs.
As part of our service, we deliver high-quality CAD designs and essential calculations, including U-value, wind uplift, and roof drainage assessments.


Building Regulation Compliance
Our CAD designer collaborates with architects to create bespoke designs and on-site sketches that align with SOPREMA’s installation capabilities. They ensure all details comply with current building regulations while fulfilling client requirements.
Comprehensive Calculations
U-values measure the rate of heat transfer through building elements such as, a roof, wall, or floor, measured in units of W/m²K, U-values. The lower the U-value, the better the insulation, making this calculation essential for meeting Building Regulations and Standards. Our team ensures all calculations are accurate and compliant, giving you peace of mind about your project’s thermal performance.
For roofs with multiple areas, such as pitched roofs with many segments, our designer provides detailed, colour-coded drainage plans which help to visualise roof performance.
We offer comprehensive WuFi calculations, guiding you from initial evaluation to full, detailed reports. Our service includes assessing whether your intended build-up will perform as expected, making necessary adaptations, and delivering in-depth reports. These reports feature clear graphs, outline the tested parameters, and provide precise results detailing acceptable limits.
Wind uplift is the upward force exerted by wind on a structure, which can cause damage or failure if not properly accounted for. We ensure your project meets wind load requirements with precise calculations tailored to your system.
Our Technical Sales Managers offer a refurbishment support service including:
- Core samples of existing roof areas
- Summary of condition report
- Recommendations
- Specification of works and system specification
Ongoing Support for Your Project
SOPREMA stands by your side at every stage of your project. Before construction or refurbishment works begin, our designs and calculations help you understand how a certain system is going to be installed. We remain on stand-by while the works are underway, in case any changes are required. After successful completion of your project our CAD designer will follow up to ensure details are updated and calculations match, ensuring peace of mind for warranties
