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

How much does thermal insulation of a house cost in Cluj-Napoca?

The cost depends on area and insulation type. A facade with 10 cm polystyrene averages 60-120 RON/sqm including materials and labor. A 150 sqm facade can total 9,000-18,000 RON.

What's more effective — polystyrene or mineral wool?

Expanded polystyrene (EPS) is cheaper and easier to install. Mineral (basalt) wool offers better acoustic insulation and is fire-resistant. The choice depends on budget and building requirements.

How much can energy bills drop after insulating my home?

Studies show a well-insulated home can reduce heating energy consumption by 30-60%. The investment payback period is typically 5-10 years.

What polystyrene thickness is recommended?

Current standards recommend a minimum of 10 cm for facades and 15-20 cm for roofs. The greater the thickness, the better the insulation, but cost increases proportionally.

What is graphite-enhanced polystyrene and why is it better?

Graphite-enhanced EPS (grey EPS) has a thermal conductivity coefficient 20-30% lower than standard white EPS. This means better insulation at the same thickness.

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.
