Thermal Insulation Of Walls: How Does It Influence Hvac Heating Consumption?

Many residential buildings have become true energy predators. This is largely due to the fact that the first regulations on thermal insulation for walls, roofs, and windows have been practically non-existent until the 1980s. Found out here about Greenwood Furnace Repair Company

A well-insulated building consumes less energy because it better conserves the temperature inside. In contrast, poor thermal insulation generates more expenses in the heating bill since heat escapes through walls, ceilings, and windows.

Thermal insulation on walls

Thermal insulation of walls and walls can be approached in three ways:

  • Exterior Thermal Insulation System – This action consists of acting on the exterior facade of the building. Its main advantage is that the thermal insulation of the entire building is improved and, in addition, its exterior appearance is embellished.
  • Injection system in the air chambers of the walls. This method consists of injecting an insulating material (fiberglass, polyurethane …) into the air chamber that exists inside the walls. The great advantage it has is that it does not modify the external appearance of the building, which is why it is a situation used on those facades that cannot be altered due to their artistic or historical interest.
  • Insulation on the interior walls. It consists of improving the insulation inside the house, and it is usually done in those buildings whose walls do not have an air chamber. When carried out inside the homes, the square meters of the room are trimmed.

Thermal insulation in windows and roofs

In addition to improving the thermal insulation of walls, it is also necessary to act on the roof (roof) and the enclosures (windows and doors), since they are elements through which energy losses also occur.

In the case of roofs, the actions vary depending on whether it is flat or sloping roofs:

  • On flat roofs, the thermal insulation process is easier because it can be carried out on the roof waterproofing.
  • On sloping roofs, the process is more complicated and can be approached in two ways: isolate between the chamber that joins the roof and the last slab, or raise the tiles to place a thermal insulation system underneath.

In the case of roofs, the following actions can be carried out or have been carried out:

  • In flat roofs, the thermal insulation process is easier because it can be performed on the roof waterproofing.
  • In sloping roofs, the process is more complicated and can be approached in two ways: isolate between the chamber that joins the roof and the last slab, or raise the tiles to place a thermal insulation system underneath.

As for the windows, the old metal or wood will be much less insulating than the more modern models, with quality materials, such as carpentry of some non-conductive material such as PVC, or profiles and glass with a low U value. ( Numerical value indicating the insulating capacity of the glass ).

Other aspects of improving

In addition to improving the thermal insulation of walls, roofs, and windows, it is convenient that energy rehabilitation also deals with:

  • Insulate Floors and Ceilings. It is advisable to install a thermally insulating material on ceilings in contact with living spaces. And also on floors that are in contact with non-habitable spaces, that are supported on the ground or that are in contact with the outside air.
  • Improve the thermal insulation of interior partitions, partitions that separate the houses from different neighbors, and the walls that separate the common areas (elevator boxes, landings …).
  • Install a thermal insulating material in hot or cold water pipes. This prevents heat losses in the hot water transport and also corrects possible condensation in the cold water pipes.
