Junctions · Detailing
Thermal bridging and construction-detail advice
Junction strategy reviewed as part of fabric performance, SAP and buildable construction detailing.
Send a project
Overview
Heat loss at junctions can materially affect the performance of a dwelling. The right response depends on the calculation route, available detail sets and the proposed construction. We help designers understand the effect of junction assumptions and coordinate appropriate details without overstating unconfirmed accreditation or values.
Project requirements vary by building type, location and timing. Send us the project information and we will confirm the right assessment route before providing a quotation.
Particularly useful for
- SAP designs sensitive to junction performance
- Non-standard wall, floor or roof interfaces
- Drawing packages needing coordinated detail references
- Early comparison of construction approaches
Our approach
- 01
Review the construction form and proposed junction strategy
- 02
Identify the junctions relevant to the assessment
- 03
Coordinate recognised or project-appropriate details where available
- 04
Explain assumptions clearly within the energy assessment
What is included
A review of the proposed junction strategy and its implications for the energy assessment, with relevant detail references and assumptions coordinated with the project information. The agreed scope identifies where further evidence or specialist analysis is needed.
Information to send
Send the proposed construction details, wall, roof and floor build-ups, available junction references and the relevant SAP information. Identify non-standard interfaces and any changes from the construction represented by a published detail set.
Scope, fees and timing
Junction advice is distinct from commissioning a new project-specific psi-value calculation. Do not assume bespoke numerical modelling or thermographic site surveys are included; the quotation will identify any additional specialist work required. Values must be supported by evidence appropriate to the actual construction.
Based in Lincolnshire, we support architects, builders, developers and homeowners across the county and throughout England. Most calculation-led work can be reviewed from suitable digital drawings. Send the project location, stage and required date so we can confirm the scope, fee and programme before you instruct us.
