Improving the insulation of our home is a great decision. Having a good temperature at home can be a great improvement in comfort and, in the long run, it will mean significant savings on the energy bill.
Although homes built in recent years meet more stringent insulation requirements, if our home is a few years old it is likely that energy efficiency is not its strong point. When reforming a home to improve its insulation, there are several elements that can be acted upon: ceiling, walls, floor, windows and front door.
Although good insulation is appreciated in any home, there are signs that may indicate that its improvement is especially necessary: in locations with very extreme temperatures, when the energy bill is very high or if there are, for example, humidity problems.
Along with the cost of labor, the cost of the reform will also be added to the cost of the materials to be used, which can make a significant price difference. In this sense, there are materials on the market with high insulating capacity that are also quite inexpensive, such as glass wool, polyurethane foam, cellulose and cork.
Regarding the replacement of elements such as windows and doors, there are also different options in terms of the materials to choose, higher or lower price. But, in many cases, this higher cost ultimately translates into savings in heating and air conditioning consumption.
Insulate the walls, ceiling and floor
If the property is in contact with the roof of the building it is convenient to know that 35% of the heat from a home can escape there. To insulate the ceiling, if there is sufficient height, the most recommended reform is to place a false ceiling below the original, which will be filled with an insulating material. There are also insulating paints that deflect heat, but they are not the most effective solution.
If we talk about insulating walls, the best option is the plasterboard placement a few inches from the original, which generates an intermediate air layer that is filled with insulating material, such as cork or glass wool, with prices of approximately 10 euros per square meter, or polyurethane foam, even cheaper.
With this solution, in addition, humidity problems can be tackled. In fact, in this chapter cork is a highly recommended insulating material, as it is resistant to humid environments, contrary to what happens with polyurethane foam.
The ground can also be a source of cold in winter. In this case, an efficient alternative in case underfloor heating is not within our reach is the laying decking with insulation underneath, which will also improve acoustic insulation. Carpet, and also rugs, are another alternative to prevent heat loss.
Change windows and doors
Another element with a large surface in contact with the outside, and on which the thermal and acoustic insulation will depend a lot, are the windows. To the extent that can reduce energy losses in a building by up to 70%. Replacing the old windows with others with insulating material and glass is therefore essential.
At this point in the design of the renovation, users tend to doubt about what type of windows will compensate more if both the insulating capacity and the price are taken into account. Regarding the price, PVC windows can be somewhat more expensive than thermally broken aluminum windows (about 10%); but when it comes to insulation it is the most suitable material, so in the long run it will be worth choosing PVC. The result will be a considerable difference in both temperature and noise level.
The recommendation of the specialists is to opt for PVC windows with double glazing, with glass with low-emission treatment, capable of reflecting energy. And they also insist that the choice of glass and the installation of insulating blinds and drawers will complete the function of the window itself.
The door of the home is another point of the house in contact with the outside through which heat and cold are lost. Can be replaced by a thermally insulated door, with isophonic gasket to help a more hermetic seal and overlapping plate at the bottom.
