Installing floor heating is an investment in both comfort and energy efficiency. In order to take full advantage of it, however, it is essential to pay sufficient attention to thermal insulation. Bricknest, specialist in building materials and modern installation techniques, explains why insulation plays a crucial role in floor heating systems, which materials are most suitable and what points to consider when installing.
The role of insulation in floor heating systems
Insulation under floor heating determines the performance and energy efficiency of the system. It performs several functions that directly affect the comfort and cost of heating.
Prevent heat loss
The main purpose of insulation is to limit heat loss to the subsoil — for example to the basement or foundation. Without a proper insulation layer, a large part of the heat disappears “into the ground” instead of heating the room. This results in higher energy consumption and unnecessary heating costs. Good insulation boards act as a thermal barrier that sends heat up exactly where it is needed.
Improving comfort
High-quality insulation ensures uniform heat distribution over the entire floor area. This creates a pleasant feeling and prevents cold zones. In addition, a well-chosen insulation material reduces the heating time of the floor, which is especially noticeable in winter. A well-insulated system responds faster, keeps the temperature stable and creates a comfortable and comfortable indoor climate.
Materials for insulation of floor heating
Various insulation materials are available for floor heating, each with their own characteristics and benefits. Bricknest recommends the following solutions, depending on the type of space and the desired insulation level.
Expanded polystyrene
Expanded polystyrene, better known as EPS, is one of the most commonly used and affordable insulation materials. It combines excellent thermal performance with light weight and easy installation, making it ideal for both new construction and renovation.
- Advantages: low cost, moisture resistant and good thermal insulation value.
- Cons: susceptible to mechanical damage and flammable.
We recommend using higher density EPS because it offers better load-bearing capacity and longer life.
Foil insulation
Foil insulation consists of several layers, including an insulating foam layer (such as polyethylene foam) and a reflective aluminum foil. The foil reflects heat upward, which significantly improves the efficiency of the floor heating system.
- Advantages: high efficiency thanks to the reflective effect and additional watertightness.
- Cons: costs slightly higher than EPS and requires careful placement to keep the foil layer intact.
Foil insulation is the perfect choice for those who strive for maximum energy efficiency and a sustainable heating system.
Features of the installation of insulation
The correct application of insulation foil under floor heating is a decisive step for the performance and durability of the entire system. Careful installation prevents heat loss and increases efficiency. Bricknest recommends that you use the following guidelines when installing.
Technical Recommendations
When installing insulation, several technical factors play a role that directly affect the efficiency of the system:
- Thickness of the insulation: the required thickness depends on the subfloor and the climatic conditions. A minimum of 5 cm is usually recommended for living areas.
- Waterproofing: check that a waterproof layer is present; if not, apply a foil to prevent moisture infiltration.
- Moisture protection: protect the insulation from direct contact with moisture by placing a vapor barrier on top before the screed is poured.
- Connection: make sure that the insulation boards connect seamlessly to prevent thermal bridges and energy loss.
