What this work involves
Discuss internal or external insulation and assess the complete build-up, including junctions at walls and roof windows.
- Internal or external approach
- Junctions and vapour behaviour
- Internal finishes and ventilation
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Compare glazing and shading as connected envelope components.
What the drawing needs to explain
Record window orientation, opening elements and existing shade. Add the main use periods so a specialist can assess the comfort question concretely.
Allow for later maintenance
Keep operating instructions and maintenance agreements for the different systems together. Record where filters and inspection points must remain accessible.
Which trade-off matters?
More glazing does not automatically call for active cooling. Compare window size, shading and use first, then assess which technical provisions are appropriate.
Cost factors for this service
Costs depend on roof shape, access, build-up and reinstatement. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for roof insulation. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging roof insulation?
Thickness alone is not enough. Performance also depends on material, junctions and the existing roof assembly.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
