Energy efficiency
Polyurethane Foam Insulation: A Complete Guide
Find out how polyurethane foam insulation works, the full benefits and how you save 40-50% on energy.

What is Thermozolation?
Thermal insulation is a process of applying an insulation material to reduce the heat transfer between the inside and the outside. The most efficient and modern method is the use of polyurethane foam.
Benefits of Thermozolation
- Energy saving: 40-50% reduction in heating costs
- Thermal comfort: Constant temperature throughout the house
- No thermal bridges: Foam adapts to any shape
- Sustainability: 25-year warranty with ISO 9001 certified premium materials
How does polyurethane foam work?
Polyurethane foam shall be applied by spraying. It expands and fills all small gaps, creating a complete thermal barrier without cracks. The process takes 1-2 days and does not require the dismantling of the old walls.
Costs and ROI
The investment in thermal insulation is recovered in 2-3 years by savings on gas bills. After that, you benefit from cheap energy for the next 25 years.
