Floors and ceilings insulation

Floor and Ceiling Insulation with Polyurethane Foam

The plank between the floors or between the last room and the roof space loses 15-20% of the heat of the house. Polyurethane foam applied to the ceiling or under the floorboard creates a perfect thermal barrier.

We choose the right type of foam

We use exclusively high-quality polyurethane foam in two variants, each optimized for specific conditions.

Closed Cell

High density, waterproof. Ideal where there is contact with humidity or high mechanical resistance needs.

  • ✓ 100% waterproof
  • ✓ Higher R-value (6.5/inch)
  • ✓ High mechanical strength
  • ✓ Ideal for foundations, exterior applications and tanks
Open Cell

Ușoară și flexibilă, permeabilă la vapori. Excelentă pentru izolație fonică și spații interioare.

  • ✓ Excellent sound insulation
  • ✓ Very lightweight
  • ✓ Vapour permeable
  • ✓ Ideal for lofts, interior walls and attics

Why Polyurethane foam?

Quick on-the-spot application

Foam applies directly to the existing ceiling. No demolitions, no excessive dust.

100% surface cover

No point, no insulated areas. Complete and uniform layer.

Reduction of noise between floors

Open-cell foam insulates excellent sound. Increased comfort.

Reduced weight

The foam is light. It does not require the layout of the board.

Compatible with installations

Foam surrounds pipes and cables. It doesn't block access to installations.

Guarantee 25 years

Permanent solution without maintenance.

Types of Projects

Subspace ceiling under roof

We insulate the ceiling of the last room under the roof. The most effective point of insulation.

between floors between floors

Reduction of noise and thermal losses between levels.

Unfurnished attic space

insulate the floor of the roof space. Cheaper than insulation of the roof.

Basement and subsoil

We insulate the basement ceiling — the warmer ground floor.

Industrial Tavan

industrial buildings and high ceiling warehouses. You're saving a lot of heat.

Tavan Between Apartments

Block solution — noise reduction from the upper neighbors.

Frequently Asked Questions

Plank or Roof — What Is More Is insulated?

Depends on whether the attic is arranged. Unused roof space — insulate the plank (cheapier). Liveable attic — insulate the roof.

Can I insulate the ceiling without raising the floor?

Yeah. We apply foam to the ceiling in the room below or from the attic above.

How thick does the foam layer have to be?

Minimum 5cm closed cell or 10cm open cell for optimal thermal efficiency.
