Services / Attic and interior insulation
Attic and interior insulation
Comfort under
every roof.
Attics and interiors need insulation suited to their structure. We help plan the layers, choose materials and define the installation scope.
We start with the structure
We check access, the condition of building elements and the design solutions. We discuss how the rooms will be used and the expected finish.
Technology suited to the application
Mineral wool, PIR boards and PUR foam serve different purposes. We first assess the structure and design requirements, including moisture control and ventilation.
Continuous insulation and sealed joints
We agree the thickness, layer arrangement and details around windows, service penetrations and junctions. Work may include preparation for further interior finishing.
What to prepare
Roof plans or sections, attic photos, approximate area and room-use plans are helpful. If documentation is unavailable, we start with a site visit.
Poradniki: Attic and interior insulation
Insulate the roof slopes or the ceiling?
First decide whether the attic will be heated living space or unused space above the home. This determines where insulation goes and the finishing scope.
Prepare a roof section and photos of accessible layers. Before closing the lining, agree insulation continuity and moisture and ventilation solutions.
What should an attic estimate include?
Separate preparation, insulation, sealing layers, framing and plasterboard. Mark roof windows, chimneys, access hatches and service penetrations.
If the loft will be used for storage, provide a suitable access walkway. Do not treat exposed soft insulation as a usable floor.

FAQ — frequently asked questions
Does thicker insulation always solve the problem?
Material properties, insulation continuity and correct detailing matter as well as thickness. The construction build-up should suit the building, not merely the available space.
Does insulation include plasterboard?
It may, but this must be included in the scope. Insulation alone and complete attic lining are different order options.
Must leaks be repaired before insulation?
Yes. First remove the cause of moisture and assess the structure and existing layers.
Can items be stored on an insulated ceiling?
This requires a properly designed floor or walkway and verification of permissible loads. Do not load soft mineral wool directly.

We confirm the final scope, materials and payment basis in an individual offer before work begins.
Attic insulation — frequently asked questions
How is insulation thickness selected?
Insulation thickness depends on the design, material, existing construction and required thermal performance. Attics also need a plan for airtightness and moisture management.
Can attic insulation be combined with finishing work?
Yes, the scope can include plasterboard lining and preparation for further interior finishing.
