Attic insulation
An insulation approach matched to the attic, existing build-up and intended use.

Insulating a pitched roof from the inside
Internal roof insulation involves more than placing material between battens. Existing layers, moisture behaviour, ventilation, connections and the later finish must be considered as one build-up.
A considered build-up
The existing roof build-up sets the starting point
A pitched roof may already contain membranes, insulation, sheathing or finishes. We account for what is visible and known when assessing an appropriate next step.
Moisture and ventilation context forms part of that assessment. We do not offer a universal construction recipe: the right layers and detailing depend on the specific property and chosen solution.
Keep the attic within the insulated zone
When internal roof insulation may fit
For attics intended to sit inside the heated zone.
- A pitched roof that is accessible from the interior
- An attic used as a practical or heated room
- A renovation combining insulation with a new sheet finish
- Roof surfaces around an existing or replacement roof window
SCOPE
Technical context we review
The edges and interruptions matter as much as the main roof surface.
- Existing roof sheathing and known layers
- Known moisture marks and ventilation context
- Battens, knee walls and interruptions
- Connections to walls, floors and roof windows
Insulation values and layer build-ups are only tied to a specific, documented solution.
METHOD
A build-up for each property
Technical choices should be traceable and executable.
Use and outcome
We discuss the attic function and intended finish.
Existing layers
Visible build-up, access and relevant concerns are inventoried.
Develop the details
The insulation zone, connections and possible finish are coordinated.
Installation
The agreed internal insulation work is carried out.
Finishing
Where included, sheet and detail finishes meet the selected build-up.
BUILD-UP AND MATERIALS
Materials follow the building context
Not every insulation product or vapour-control layer is automatically suitable for every roof. Existing layers and drying direction are part of the technical assessment.
Ventilation of rooms and construction elements also cannot be addressed with a generic statement. Where specialist assessment is needed, that must precede confirmation of the final scope.

Insulation and further finishing
Real working images of insulation, sheet preparation and finishing; they do not prescribe one fixed layer build-up.
The photographs show real Noordvaro work and relevant working situations. They are not a before-and-after sequence from one project.

Internal roof insulation questions
Why the building situation determines the solution.
Can every pitched roof be insulated from inside?
Not with one standard build-up. Existing layers, condition, access, moisture and ventilation context require assessment first.
Which Rd or Rc value do you provide?
That depends on the specific selected and documented solution. We make no universal insulation-value promise on this page.
Why does moisture matter?
New layers change how heat and moisture move through the construction. That is why the existing build-up belongs in the assessment.
Is ventilation automatically modified?
We assess the relevant context but do not name a standard measure without knowing the situation. The agreed scope determines what is carried out.
Can sheet finishing be included straight away?
Yes, where appropriate, insulation and interior finishing can be coordinated. Materials and details are agreed first.
Could a subsidy apply?
A subsidy may apply to certain insulation measures. Conditions change and depend on the property, the measure and the current scheme.
