Reducing energy consumption through good insulation

Published on : 24 June 20206 min reading time

Do you want to be able to reduce your energy consumption so that you can spend less on heating? A good insulation of your home helps to reduce this energy consumption and will save you money. Here’s what you need to know about it.

Finding the right solution to thermally insulate your roof

Poor roof insulation is particularly energy-intensive, as it is responsible for heat losses of at least 30%. This is a large percentage, which of course means that you have to spend more on heating in winter! This means that you consume more wood or fuel oil, for example. But that’s not all, poor insulation also causes you problems in the warmer months, when the temperature rises, because the heat “enters” your home through the roof. In order to remedy these problems, which are detrimental to your well-being and also to your finances, it is particularly important for you to find an effective insulation solution. This will help you, among other things, to insulate your entire roof. Regardless of whether you have a relatively flat roof or a conventional pitched roof, you really should not neglect to have a good (standard) insulation of your entire roof. Not only will you gain in terms of comfort, but also in terms of your heating (winter) and electricity (summer) budgets.

How can you perfectly insulate your entire roof?

The insulation of a house concerns important points: the floors, the walls, and everything that concerns the roof as a whole. Indeed, a defect of insulation on your roof, will have the consequence to contribute largely to decrease the insulation of your house. Insufficient attic insulation will increase your energy consumption, with the consequences we all know: you will consume more fuel to heat your home with wood, oil or electricity, and your heating budget will inevitably suffer. Because of poor insulation, you will be cold, even though you have pushed the level of your heating! In concrete terms, if the floor under your roof is not insulated, or is poorly insulated, your home will consume more energy, since this floor will let both the cold in the wrong season and the heat in the summer. This has the consequence of disrupting your comfort in your home, on the one hand, and on the other hand, of course, it increases your energy consumption for heating in the winter, and for air conditioning or fans when it is very hot. When we talk about roof insulation, we must also think about the attic, which also needs to be insulated. The purpose of this is to reduce heat loss to the outside and cold air infiltration inside the house.

What materials should be used to insulate a roof?

Are you wondering how best to insulate your roof and what materials are used to do so? To effectively insulate your roof, an insulation professional will use different means, depending on whether the premises are heated and occupied (bedrooms or other rooms), or unoccupied (with no plans to use them). It is also important to know that a thermal insulation will be different, depending on whether your roof is flat, or has two classic sloping sides. Indeed, there are insulating materials adapted for each roof. The insulation of the spaces, under the roof, fitted out and heated, can generally be done with XPS polystyrene panels for your flat roof. These panels are often recommended for this type of roof. If you have a roof with two sloping sides (for example), the insulation professional will, to best insulate the attic, use rock or glass wool. This type of material comes in rolls, which are simply unrolled on the floor. They have the particularity, among other things, to insulate correctly, to be non-flammable, and to considerably attenuate all the noises coming from the outside. When the spaces under the roof are not heated, nor used as an additional living room (bedroom, dressing room, office, playroom, bathroom, etc.), roof insulation can be made with rock wool, glass wool or cellulose wadding. The rock or glass wools are installed in the same way as before, while the cellulose wadding will be distributed over the entire floor surface. The cellulose wadding can be in the form of rolls to be unrolled, but also in bulk or in panels made of the material and textile up to 15%, which are compressed together. Depending on the case, the insulation professional can also offer another solution, to insulate all the unused space under the roof. One must be aware that one wants to make one’s attic in the future, since using cellulose wadding or other material projected or dispersed on the floor makes it impossible to use the space afterwards (or difficult to clean). If you plan to use your roof space in the more or less distant future, you should use rock or glass wool, which can be moved easily.

Insulate to reduce energy consumption

Proper insulation helps to ensure that no calories are lost between the roof and the rest of the house. In other words, heat is not wasted and does not go outside the home. At the cost of properly heating a home, it is essential for the home owner to have the insulation of the attic and roof carefully checked. A thorough diagnosis will allow you to know what you are dealing with, concretely, concerning your roof, as a whole. From there, you will be able to call upon a professional recognized in the total insulation of your roof, so that he can take care of the insulation work to be carried out.

The benefits of properly insulating your home

Making sure that the house is well insulated means, first of all, starts with being sure that you will enjoy more pleasant living conditions and comfort than before. Indeed, when it is very hot outside, the heat enters the house through the roof. A lack of insulation means that very quickly, the heat rushes through the floor, and “heats” a home where you are looking for coolness. Living comfort is disturbed during the day, and especially at night! Children and adults are therefore victims of this heat which remains in the dwelling. Air conditioners and fans have to be used for long hours. On the other hand, during the winter period, the floor lets the cold pass through, and the wind can also cool the house on its side. This implies discomfort for the occupants of the dwelling, who are cold, raise the thermostat, but still feel the cold anyway. In a second step, having the roof fully insulated will clearly help to reduce energy consumption. The amount of money spent on heating will thus be seriously reduced. In addition, you can benefit from a tax reduction, if you qualify, for your roof insulation. In front of all the possible advantages, for you and your budget, there is no hesitation to have.
