Building Physics Reports: U-values, WUFI & Junction Solutions

Desktop U-value calculations, WUFI hygrothermal assessments and practical thermal-bridge and junction solutions. Straightforward defined reports from £100.

Discuss your concern

The problem

An architect, surveyor, contractor or homeowner needs a clear technical answer about insulation performance, a wall or roof build-up, moisture risk or a difficult thermal junction.

What an investigation could involve

Agree the technical question, drawings, material properties and deliverable. Undertake an appropriate U-value calculation, 2D thermal-bridge model or WUFI hygrothermal assessment. Where requested, compare practical junction and building-envelope improvements against agreed design constraints.

What you could receive

A scope-specific PDF report with results, stated assumptions, limitations and practical design options where supported by the assessment. Straightforward single-build-up U-value calculations or initial desktop junction reviews start from £100. Detailed ψ-value modelling, WUFI assessments and multi-junction solution reports are quoted individually.

Building physics & junction solutions

U-values, WUFI, 2D thermal bridging and practical junction recommendations can be commissioned as a single agreed technical scope. Straightforward desktop reports from £100; detailed modelling and multi-detail reports quoted individually.

Scope and limitations: Desktop calculations depend on supplied information and cannot verify concealed as-built conditions. Design proposals also require separate fire, structural, weatherproofing, manufacturer and statutory checks where relevant. The £100 entry price does not include a full WUFI assessment or a detailed thermal-bridge calculation. An appropriate scope, necessary competence, insurance, timing and survey conditions must be established before any paid investigation.

Free initial conversation & no-obligation quotation

Tell us about your building or junction.

Describe your concern, junction or project and optionally attach photographs or PDF drawings. We can review your enquiry and discuss a suitable scope, quotation and appointment options. Your initial conversation and quotation are free; site investigations, thermal modelling and detailed technical reports are scoped and priced before you agree to proceed. An initial enquiry review is not an inspection, diagnosis or formal report.

Maximum three images, up to 8 MB each. Please do not include people or sensitive personal documents.

Up to two PDF files, 12 MB each. Remove confidential drawings, names and personal information you do not have permission to share.

There is no charge for the initial conversation or quotation, and no payment is taken through this form. You can also email vertexenvelope@outlook.com.
