As you can see, besides the main “consumers” that we have already dealt with in the previous text, there is heat drains that you probably did not even know. Through them, only a small part of the heat is lost, but it is very important to us that these are the places where we can make the greatest savings ourselves. How much time do you need to shake well with all the installation pipes and electrical outlets? Perhaps not one afternoon, and they give 15% of the total losses in the sum total! If you attach windows, doors and individual ventilation openings (which also does not require any major investment), you will see that you can eliminate over 60% of all possible heat sinks in your apartment or home. If you have time and few resources, we strongly recommend that you embark on the ceiling of the basement and the floor of your attic with synthetic mass or polymer insulating plates.

Basic types of insulating materials

Before you get to work, get acquainted with the basic types of insulation materials:

Type of Setting Where Applicable Basic Benefits and Disadvantages:

  • Non-woven materials (in bales or rolls)
  • Glass wool
  • Rockwool (“Rockwell”)

They fix themselves with a “barbecue” from the lining or between the layers of the wall. In the finishing of the walls, floors, and ceilings, as well as the roof constructions, Laki for the “do-it-yourself” installation: almost every novice knows how to compose a “barbecue” from slats, especially in smaller areas traffic.

Dishwasher: For safe installation, HTZ equipment is required: gloves and mask/face goggles

  • Foam materials
  • Foam wool
  • Fiberglas
  • Polyurethane foam

Sprays or bubble into recesses using a special tool. Open or inaccessible cavities in the walls, as well as small cavities around installation tubes, windows etc. … It is most often used to repair existing insulation (application into inaccurate cavities or holes of irregular shapes)

Flat materials

  • Extruded polystyrene foam (XPS)
  • Expanded polystyrene foam (EPS)
  • Polyurethane foam
  • Poly-iso-cyan-uratic foam
  • Cork

Inner walls: Because of its flammability and for aesthetic reasons, it is always covered with a layer of clay or plasterboard plates with a thickness of 1cm or more.

Exterior walls: thick panels are used, mandatory finishing with a layer resistant to atmospheric influences (various types of mortars with additives and facade coatings). Basement walls;

Nonventilated roofing structures of low inclination The largest insulation power in relation to the thickness of the layer and the price of all the above materials. All types of panels are available with a large number of warehouses and are relatively inexpensive, and simple to do “do-it-yourself” installation.


  • Plastified paper
  • Polyethylene foil with air bubbles
  • PVC foil
  • Plastic cardboard

Usually in combination with plates and glass wool, especially on surfaces with a lot of moisture (roof structure). Roof constructions, ceilings, floors, exterior walls … Cheap and easy to install. Disadvantages: The efficiency depends on the direction of the heat flow. The possibility of unwanted condensation of moisture.

Liquid insulators

  • Perlit
  • Vermiculite
  • Vaserdiht

They are not strictly intended for thermal insulation but are often used in combination with other means, especially for work in older homes.

When you’re done with these “little things”, it’s time to face the last challenge: doors and windows. Do not drop this step, because it can turn out that just carpentry is the biggest “swallow” of heat in your home.
