The energy efficiency of a building is one of the most important aspects that affects the comfort of the occupants and the amount of heating and air conditioning bills. The constant increase in energy prices makes the topic of choosing the right insulation increasingly important. Is it possible, and how, to improve a building’s energy efficiency using stone wool insulation?
Energy efficiency of a building – why does it matter?
In recent years, there has been more and more talk about energy efficiency, mainly in the context of saving and reducing the energy required to heat a building. With well-designed solutions, energy is used efficiently and energy losses are kept to a minimum.
The use of materials that improve a building’s energy efficiency is of great importance not only in terms of reducing running costs and improving living comfort. Improved performance plays a major role in terms of ecology – it reduces the amount of greenhouse gases that have a destructive effect on the environment.
What makes Rockwool stand out?
Rockwool products are insulations that are made from natural stone wool. Today it is one of the best and most effective thermal insulation materials used in the world. Rockwool products stand out:
- a low thermal conductivity coefficient, which means that they provide high insulation;
- fire resistance – wool in fire class A1 is a non-flammable product;
- durability and dimensional stability, which means that even over time the product parameters remain unchanged;
- high vapour-permeability, thanks to which the material allows the walls to “breathe”;
- good sound insulation, protecting the interior from noise from outside, as well as from other rooms and floors.
Rockwool not only improves the energy efficiency of a building, but also has a positive effect on the comfort of the inhabitants.
Using Rockwool for energy savings
The great advantage of Rockwool is the variety of products. Depending on where they are installed, they are adapted to the specific needs of the space. The range includes stone wools for:
- external walls;
- internal walls and partitions;
- sloping roofs and attics;
- flat roofs;
- floors and ceilings.
Each of these places is exposed to different factors, so the parameters of the products must be adapted to specific needs. For the interior of the building and the partition walls, acoustic insulation is very important to ensure the comfort of the occupants every day. External wall insulation, on the other hand, should effectively protect against heat loss in winter and excessive heating in summer.
How do you choose the thickness of insulation?
Energy efficiency also depends on the thickness of the insulation layer, which is selected individually. When designing a building, consider:
- climate zone;
- the type of envelope (wall, ceiling, roof);
- the specific design requirements;
- the energy performance of the building.
For external walls, an insulation thickness of 15-20 cm is recommended as standard, while for roofs the value is up to 30 cm or more. On rockwool.com/en you can choose the right thickness of dedicated stone wool for different installation locations.
What can be done to really improve the energy efficiency of a building?
To make a real improvement in the energy efficiency of a building, Rockwool insulation needs to be matched to specific factors. In modern buildings, specific solutions are recommended at the design stage, taking into account the needs of the construction technology or climate. For older and retrofitted buildings, it is best to select products in consultation with specialists. An energy audit can be a good solution.
Summary
Improving the energy efficiency of a building involves considerable expense. However, it is worth treating the cost as an investment that will lead to real energy savings and lower bills. The basis is the right choice of materials, so it is best to choose Rockwool insulation because these are proven and durable solutions that do not lose their properties over the years.
