Co-ownership: The hunt for heat loss

Condominiums are also affected by the energy transition. Among the work to be carried out to reduce energy consumption in the area is the insulation of buildings. The risks of overconsumption are in fact most often caused by energy losses. As part of a renovation, it will be necessary to establish a diagnosis beforehand in order to highlight the priority works. Here are the renovations to consider to fight against heat loss in condominiums.

Insulating the walls from the outside

Another effective solution to combat heat loss in condominiums is to create a cover around the building in order to reduce thermal losses. According to the law on energy transition, insulation is compulsory if the renovation works represent at least 50% of the facade.

Insulating the walls from the outside significantly reduces energy consumption. You will be able to achieve savings of up to 30% if the work has been carried out under the best conditions. Insulating the facade from the outside is therefore a good solution to reduce greenhouse gas emissions and save energy. It will also be an opportunity to improve the aesthetics of the building.

No intervention will be necessary in the apartments, everything is done outside. There is thus no impact on the interior dimensions of the dwellings. However, the ITE can be more or less complex depending on certain architectural or technical constraints.

Insulation of low floors

Buildings lose heat through the roof, but also from below. Part of the heat accumulated on the floors escapes through unheated spaces. These include the boiler room, the car park, the cellar, etc. It is in this context that the insulation of the low floors comes into play, which consists in applying an insulating material to the level of the basement ceiling. To obtain sustainable and efficient work, you can call on an expert like Hellio who offers quality support.

Insulation techniques for low floors

Insulating floors, also called basement insulation, is done using two main techniques. First, there is the flocking, which consists of projecting the insulation on the ceiling of the basement. Subsequently it will swell in order to cover the entire surface. This method suitable for spaces with irregularities. The other method is the installation of rigid rings which is used for regular surfaces. Here, insulating plates are fixed with dowels. To avoid heat loss, it is imperative that the panels are contiguous.

In both cases, the insulation must remain visible or be wrapped in a coating or plate. This will provide a more aesthetic rendering to your condominium. The floor must also be properly ventilated to avoid the risk of moisture infiltration in the insulating material. There is a third technique which designates insulation from above. It will be a question here of setting up rollers in the heated rooms. However, this solution is rarely used because of its many constraints: impacts on occupants, cost, complexity, rise in ground level, etc.

Which insulation material to choose?

To insulate the floors of a condominium, you have the choice between a wide variety of insulators. It will be necessary to choose according to the thermal performance of the latter and the deployed solution. You can also rely on the most commonly used insulation materials for condominium insulation.

Expanded polystyrene (EPS) consists in particular of light and solid plates with high thermal performance. These are very easy to install and affordable in terms of price. Polystyrene is generally used for renovating basements. Glass mineral wool, on the other hand, is one of the most efficient materials to use for insulating low floors. It has the ability to withstand extreme temperatures and very resistant to rodents and fire.

Insulation of the roof terrace

Insulating the roof terrace is also a possible solution for certain buildings. Very effective, it allows to make savings on heating bills (up to 20%). The work is being done on the roof terraces, with a slope of less than 5%. Insulation is placed between the vapor barrier and the waterproofing membrane or directly on it.

Window replacement

This operation allows fight against energetic losses through the windows. The presence of old single-glazed windows in a condominium can quickly cause heat loss. In order to avoid this, the installation of new windows is required, preferably with the choice of double glazing. This will improve the insulation of the common areas. Likewise, the heating or air conditioning needs in private areas will be reduced. Before starting operations, take care to consult the condominium regulations in order to have an idea of ​​the measures imposed.

The implementation of a new heating system

When your condo’s heating system is outdated, then it’s time to change it. Take the opportunity to choose an economical model that offers a real performance gain. Thanks to less expensive energy, the condominium will be able to save money. Likewise, energy requirements will be reduced due to the performance of the device.

Insulating pipes by heat insulation

Insulation is one of the solutions to combat heat loss in condominiums. It designates the insulation of hot water pipes with a heat insulating sheath covering the piping. The goal is to be able keep the water at a high temperature. The higher the building, the longer the hot water network. Therefore, the heat tends to decrease mechanically as the water travels through the pipes. Thanks to the thermal insulation, you will need less energy to heat the sanitary water and the rooms of the dwelling.

Advance in the hunt for waste

The hunt for heat loss is essential in condominiums. This goes through a lot of work including insulation. Concretely, it will be necessary to insulate the low floors, the walls, the roof, the pipes… Also do not forget that several actors intervene within the framework of the thermal renovation of a condominium. It is therefore imperative to talk to all concerned and find a quality expert to whom to entrust the work.
