House insulation that keeps the heat where it belongs

Facade, roof, loft and ceilings by one crew. We first find where your house leaks heat, then design an insulation build-up for your masonry. You know the price before the scaffolding goes up.

Uninsulated house: heat escapes through the walls, around windows, through the ring beam under the roof and the plinth.

What we insulate

Each part of the house gets a different build-up. What they share: continuous insulation, correct thickness, no thermal bridges.

Worker on a lift renovating and insulating a facade

External thermal insulation composite system (ETICS)

Facade insulation

Polystyrene, graphite polystyrene or mineral wool depending on the masonry and fire requirements. Water-resistant XPS on the plinth, base rails with drip edge, anchoring per board specification and a new render in the colour you choose.

Worker laying insulation between rafters in an attic

Between rafters, above rafters or on the loft floor

Roof and attic insulation

Habitable attics get insulation between and under the rafters with a vapour-control layer; when the roofing is replaced, above-rafter boards. An unused loft only needs the floor insulated, the fastest saving a house can get.

Technician checking a layer of blown insulation in a loft

Cellulose, mineral or wood fibre

Blown-in insulation

Loft floors, cavities in timber ceilings, sloped roofs and double-skin flat roofs. The material is blown in through a hose without dismantling anything, fills every gap and is finished in a day.

How the job runs

Five steps from the first call to handover. You know the date of each step in advance.

Site visit

We measure, check the wall build-up, base and loft. Free, no obligation.

Design and quote

Written layer-by-layer design, itemised quote, schedule.

Permits and funding

We check notification duties and prepare documents for a grant or interest-free loan if you qualify.

Installation

Scaffolding, substrate, bonding and anchoring, reinforcement, render. Inspection points are photographed.

Handover

Joint inspection, protocol with photo documentation and material warranties. Thermal image of the finished facade on request.

Questions we get asked

Do I need a building permit to insulate my house in Czechia?

Under Building Act 283/2021, insulation that does not change the appearance of the house or its fire safety usually needs no notification. If the colour or layout of the facade changes, or the house is in a heritage zone, we check with the building office for you.

Polystyrene or mineral wool?

Thermally they are close. Mineral wool is non-combustible, dampens street noise and lets old masonry breathe; polystyrene is lighter and cheaper. We often combine both: wool around windows and entrances, polystyrene on the main area.

How long does it take?

External wall insulation of a typical family house including scaffolding and render takes 3 to 5 weeks. Blown insulation of a loft floor is done in one day.

Are there subsidies for foreigners who own a house here?

The 2026 Nová zelená úsporám scheme offers direct grants for lower-income households and an interest-free loan for other owners of family houses. Eligibility depends on ownership and permanent residence in the house; we go through the conditions with you.

Do you work outside Prague?

Yes, across the whole Czech Republic with regional crews working to one specification and one inspection checklist. Site visits are free everywhere.

Tell us about the house, we will send a plan and a quote

A few details are enough. We reply within 24 hours, arrange a free site visit and send an itemised quote. You do not need to measure anything or choose materials, that is our job.
