Insulation & roofing work
The service in detail
Good insulation starts at the structure: where the roof truss and timber frame take shape, we lay the foundation for a warm, dry and long-lasting roof.
As a master-carpenter business, we always think about insulation from the timber up. When you have us build your roof truss and timber frame anyway, the matching insulation comes with it – cleanly integrated between the rafters, without thermal bridges and without coordination gaps between trades.
The result is a carefully considered build-up of timber, insulation and an airtight layer that saves energy, prevents moisture damage and noticeably improves comfort. Complementary sealing work – for example with proven alwitra membranes – is carried out in close coordination with our sister company Blang & Lauterbach, so that you receive roof and timber from one reliable source.
Whether in Mertert, Wasserbillig, Grevenmacher, Echternach, Remich, Junglinster or Luxembourg City: we give you honest advice on the insulation and protection build-up that suits your roof – and carry it out in true master-craftsman quality.
Variants & options
Insulation around the timber frame
The most effective insulation is installed where the timber sits. We insulate your roof truss and timber frame to the highest standard – between, above or below the rafters – and use a clean airtight layer to keep the warmth inside the house. This means lower heating costs and a pleasant indoor climate all year round.
- Insulation between, above and below the rafters
- Natural and mineral insulation such as wood fibre or mineral wool
- Airtight connections and vapour barrier installed correctly
- Interior insulation and timber cladding in carpenter quality
- Thermal-bridge-free build-up – matched to your roof truss
Complementary sealing – hand in hand with Blang & Lauterbach
