About this service

Thermal insulation is one of the most cost-effective investments for a home, significantly cutting heating costs in winter and cooling costs in summer. Services include insulating façades with polystyrene or mineral wool, insulating attics, lofts, and floor slabs, fitting vapour barriers, and finishing with decorative render. Correctly installed insulation eliminates thermal bridges, prevents condensation and mould, and improves comfort in every season. A specialist recommends the right thickness and material for your building and applies the work evenly, without cracks.

Frequently Asked Questions

Can I insulate only part of my home?

Yes, but specialists recommend insulating the entire thermal envelope for optimal results. Partial insulation can create thermal bridges and condensation in uninsulated areas.

How long does facade insulation take for a house?

For a medium-sized house (150-200 sqm built), facade insulation work typically takes 2-4 weeks, depending on the team and weather conditions.

Can an apartment be insulated from the interior?

Yes, interior insulation is possible with polyurethane foam or mineral wool plasterboard panels. It's less effective than exterior insulation but useful when facade work is not possible.

Does facade insulation require a building permit?

Facade insulation (polystyrene cladding) is generally considered routine maintenance and does not require a building permit for individual houses. For apartment blocks, homeowners' association approval is needed.

What warranty do thermal insulation teams offer?

Properly executed ETICS insulation systems have a lifespan of 25-30 years. Professional teams offer a 2-5 year warranty on the executed work.

How do I choose the right insulation company?

Check if the company has experience with the chosen insulation system, request references from similar projects, ask for a detailed quote specifying materials, and ensure they offer a written warranty.
