What to check before hiring a thermal insulation

Graphite-enhanced (grey) EPS is more efficient than white EPS at the same thickness
Ask for references from similar completed projects and visit a site if possible
Don't sacrifice material quality to reduce cost — poor insulation costs more in the long run
Choose a minimum polystyrene thickness of 10 cm for facades and 15 cm for roofs
Request a detailed quote specifying brand and material type
Verify the company offers a written warranty for the insulation system

Frequently Asked Questions

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.

Is roof insulation more important than facade insulation?

25-35% of building heat loss occurs through the roof. The optimal combination is insulating both facade and roof. If budget allows only one intervention, the roof takes priority.

What is a thermal bridge and how is it eliminated?

A thermal bridge is an area with higher thermal conductivity than the rest of the structure (window sills, lintels, corners). It can cause condensation and mold. It's eliminated by continuous facade insulation and correct detailing.

How much does thermal insulation of a house cost in Dej?

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.
