Insulation and soundproofing
warmer, quieter, more efficient
Insulate roof, floor, cavity wall, façade and crawl space. Soundproof walls, ceilings and floors against neighbour noise. Waterproof roofs, balconies and basements. One contractor for the full project — from survey to handover and ISDE subsidy application.
Where does a home lose heat?

Insulate your home: each building part separately
We insulate roof, attic, floor, crawl space, cavity wall, façade and basement. For each part we choose the material that fits your home, available space and the ISDE Rd requirement (min. Rd 3.5 m²K/W, cavity Rd 1.1).
Roof insulation
Pitched roof from inside/outside, flat roof with PIR or EPS.
Attic floor insulation
Fastest, cheapest measure if the attic is unused.
Floor insulation
Boards or blankets under the ground floor.
Crawl space insulation
Ground foil and chips — moisture first, then insulation.
Cavity wall insulation
EPS beads or mineral wool after endoscopic check.
Internal wall insulation
Stud wall for homes without a cavity.
External wall insulation
Highest performance and ISDE € 20.25 / m².
Basement insulation
Walls, ceiling and floor — always with damp proofing.
Pipe insulation
Heating and hot-water pipes in crawl space and shafts.
HR++ and triple glass
Glass replacement including secondary glazing for monuments.
Soundproofing against neighbour and street noise
Footfall from upstairs, speech through the party wall, tram and terrace noise. We measure where sound enters, determine impact vs airborne noise, then choose the construction.
Wall soundproofing
Stud wall on resilient channels — up to 10–15 dB.
Ceiling soundproofing
Against footfall from upstairs neighbours.
Floor soundproofing
Floating screed with Ico ≥ +10 dB for HOAs.
Acoustic glass & doors
Glazing, sealing and heavy doors.
Neighbour noise
Which measure helps — and which does not.
Dry first, then insulate
Insulation on a damp structure leads to mould and timber rot. That is why we carry out waterproofing and moisture control ourselves, in the same project.
Roof waterproofing
EPDM/bitumen, repair and renovation with insulation.
Balcony & terrace
Rubber coating or membrane including drains.
Basement waterproofing
Tanking, joints and injection against rising damp.
Moisture control
Survey first, then targeted mould solutions.
What does insulation cost per m²?
Guide prices including material, labour and disposal, excluding VAT. Labour on insulation work qualifies for the reduced 9% VAT rate. After a survey you receive a fixed price per m².
