Roof Insulation

Roof Insulation


Why should roof insulation be a priority?
No point in setting the heating to the maximum. What you need to do is insulate better: you have to take note of this to improve the energy efficiency of your home. When carrying out renovation work to improve insulation, start with roofs and roofs, the main places of heat leakage, up to ... 30%! Therefore, with roof insulation, we will achieve 30% savings thanks to lower energy consumption. But why is roof insulation a priority?

Why is it necessary to conduct thermal insulation of roofs and attics?
Raising the heating temperature, with its consequent increase in costs and pollution, is a useless and not very environmental business because in poorly insulated homes, heat seeps directly through roofs and ceilings. On average, heating accounts for 62% of energy consumption, so it is important to start by improving the heat we produce at home.

Why insulate roofs? Simple: Thermal insulation of roofs significantly reduces heat leakage, which in turn means that we need to use less heating or lower the temperature. Less consumption and pollution along with greater savings will be the direct result of roof insulation, which is becoming increasingly economical, fast and accessible.

On the other hand, did you know that good insulation is the best way to improve your home heating when cold looms? A well insulated roof and/or roof will also allow you to keep the house cool in the summer, when climate control is on.

Excellent thermal insulation protects the house from external weather conditions, whether cold or hot. If you use an air conditioning system, you can save energy at this level.

Finally, insulating the roof, roofs and attics does not only insulate from cold or heat. Isolators also provide excellent sound insulation against external noise.

Therefore, thermal insulation of ceilings and ceilings is not only necessary, but also very interesting for all these advantages. To improve our energy performance while reducing consumption and carbon emissions, we start with roof insulation.

How to choose insulation for roofs and ceilings?
In recent years, a variety of options for insulation materials for the roof has multiplied. Although fiberglass wool is still the most widely used roof insulation material in Spain (about 75%), there are a variety of materials to choose from:

• Synthetic insulators (polyurethane foam, expanded polystyrene, extruded polystyrene, etc.)
• Metal insulators
• Natural condoms of vegetable or animal origin
• Heat Reflective Coatings
• Insulators of the new generation with the latest technology

Among these different types of insulation for roofs and attics, and according to the above criteria, we can choose the one that best suits our needs and budgets. These are the most common materials:

Rock wool, mineral wool or glass wool that provide heat and sound insulation, as well as good value for money

Cork, cotton, hemp or sheep's wool, 100% natural and environmental

Cellulose filler, another environmentally friendly insulating material that is used in rare cases to insulate surfaces.

You also need to know how to choose a ceiling heat insulator that will provide good performance: for this you need to go to the resistance. The resistance of the acoustic heat insulator will depend on its thermal conductivity and thickness. All of this information is available on the product label. The concepts of performance and thermal resistance of insulation are very important to being able to access certain types of financial aid.

When is the roof and attics insulated in homes?
The answer, obviously, would be: isolate ASAP! More than a priority, thermal insulation of roofs or suspended ceilings should be the starting point for any energy renewal that focuses on lower consumption, lowering the bill and adopting more environmental behaviours.

In fact, the renovation improves the energy efficiency aimed at acoustic and thermal insulation of the roof, and increases the effectiveness of other types of work that we carry out later. For this reason, thermal insulation of the roof should be the first step in improving the energy efficiency of our homes.

Thermal insulation of roofs and attics in buildings and homes is an ideal part of the energy transition framework and environmental transformation.

Carrying out heat and sound insulation of ceilings, suspended ceilings and attics will also give us the right to access the assistance that we will mention below, which will significantly reduce the price of works.

What are the prices and subsidies for home roof insulation?
Prices for roof insulation can vary greatly. The price depends on the type of roof, as well as on the type of insulation, its thickness, the necessary work, etc. Let's take several examples:


At first glance, it may seem to us that the cost of work on improving the thermal insulation of the roof is high. But it is not. Apart from being a very profitable investment in which you can save a lot of money and energy consumption, you can also benefit from financial aid:
Insulating roofs and attics is a priority to improve our energy efficiency. Therefore, thermal insulation is the first step in improving heating, insulation against heat in summer and against noise pollution throughout the year. Less consumption means less bill and less energy.
Why is insulation important?
Insulation consists of thermal insulation of the structures of the house. Thermal insulation of the roof, along with a high-quality roof, is very important for the house. A well insulated house will not only be more comfortable, but also reduce energy consumption and thus provide more savings. There are different types of insulating panels and tiles that contribute to optimal insulation. Therefore, the selection of high-quality materials is of primary importance.
Materials suitable for thermal insulation of surfaces
To insulate the ceiling, various materials are used, both of natural and non-natural origin. There are different types of
insulating sack:
• wood fibers
• grained glass
• Cork.
• Expanded polyurethane foam.
The first type of panels consists of compressed wood fibers, which provide excellent heat and sound insulation of the ceiling. Widely used for flat surfaces.
Particleboard is made from a blend of glass with other recycled materials. It is particularly suitable for roof thermal insulation and is very resistant to water and vapor.
Those made of cork, which last longer than others, contribute to roof insulation and counteract water damage.
The latter consist of expanded polyurethane foam sandwiched between two layers of fiberglass or of the same material: they are excellent thermal insulators, water repellent and resistant.
As for the prices, those in polyurethane are less expensive than the other mentioned materials: however, the latter are natural and serve not only as excellent heat insulators but also as sound insulators.

Which covering to choose the best insulation?
The choice of roofing covering is very important to make the most of your roof thermal insulation board. This, in fact, protects the entire structure by preventing water from contacting the insulating layers. The most common covers are:
• PVC Tile
The importance of insulation board and ventilation
Using insulation for your roof includes:
• Better Living Comfort
• energy saving and economy;
• Maintenance of the entire structure.
Roof ventilation, that is, building a structure that allows air to pass between the insulating layer and the roof, is also very important. This is because it contributes to the maintenance of the board and thus to the well-being of the underlying environments. A ventilated roof, which is more expensive than a non-ventilated roof, allows the insulation to remain dry during the winter, avoiding the appearance of moisture. However, in the summer, ventilation prevents heat from penetrating into the house, which will therefore be much cooler.
