U-value Calculator
For projects using SOPREMA PIR, XPS or Multifoil Insulation products in floors, walls, pitched roofs and flat roofs.
This u-value and condensation risk calculator should be used where SOPREMA insulation is being specified independently, and the warm flat roof is not part of a complete SOPREMA insulated waterproofing system solution.
Designed to support accurate specification, the calculator allows you to select your target U-value and assess the insulation thickness and product options required for a range of common construction elements. Applications include pitched roofs, ceilings, walls, and ground floors, helping you evaluate build-ups efficiently at both design and specification stages.
Simply complete each section with the relevant construction details to generate calculated U-values based on recognised methodologies. The tool is intended to support informed decision-making by providing clear, consistent outputs aligned with SOPREMA insulation product data, helping you progress your project with confidence.
