Buitengevelisolatie: Everything You Need to Know

Buitengevelisolatie, also known as external wall insulation, is a process of insulating the exterior walls of a building to improve energy efficiency and thermal performance. It involves attaching insulation material to the exterior walls of the building and then covering it with a protective layer such as render or cladding.

In this article, we will explore everything you need to know about buitengevelisolatie, from its benefits to the different types of insulation materials available.

The Benefits of Buitengevelisolatie

1. Energy Efficiency: Buitengevelisolatie can significantly improve the energy efficiency of a building by reducing heat loss through the exterior walls. This can result in lower energy bills and a more comfortable living environment.

2. Thermal Performance: Insulating the exterior walls helps to regulate the temperature of the building, keeping it warm in the winter and cool in the summer.

3. Noise Reduction: Buitengevelisolatie can also help to reduce noise pollution by acting as a sound barrier for the building.

4. Aesthetics: Buitengevelisolatie can improve the appearance of a building by providing a smooth and uniform surface that can be finished in a variety of colours and textures.

Types of Insulation Materials

1. Polystyrene: Polystyrene is a popular insulation material for buitengevelisolatie due to its lightweight and easy-to-install properties. It is available in two types: expanded polystyrene (EPS) and extruded polystyrene (XPS).

2. Mineral Wool: Mineral wool is a natural insulation material made from rock or glass fibres. It is fire-resistant, moisture-resistant, and provides excellent thermal and acoustic insulation.

3. Polyurethane: Polyurethane is a high-performance insulation material that is suitable for use in extreme temperatures. It is also lightweight and easy to install.

4. Phenolic Foam: Phenolic foam is a rigid insulation material made from phenol formaldehyde resin. It is highly resistant to fire and moisture and provides excellent thermal insulation.

Preparing for Buitengevelisolatie

Before installing buitengevelisolatie, there are a few things you need to consider:

1. Building Regulations: Ensure that your building complies with local building regulations and obtain any necessary permits before starting the installation process.

2. Surface Preparation: The surface of the exterior walls must be clean, dry, and free from any defects before installing the insulation material.

3. Ventilation: Ensure that the building has adequate ventilation to prevent the build-up of moisture, which can cause damage to the insulation material and the building structure.

4. Professional Installation: Buitengevelisolatie should only be installed by a professional contractor who has experience with the installation process.


1. What is the cost of buitengevelisolatie?

The cost of buitengevelisolatie depends on various factors such as the size of the building, the type of insulation material used, and the complexity of the installation process. On average, the cost can range from €70 to €150 per square metre.

2. How long does buitengevelisolatie last?

Buitengevelisolatie can last for up to 25 years with proper maintenance and care.

3. Can I install buitengevelisolatie myself?

Buitengevelisolatie should only be installed by a professional contractor who has the necessary experience and expertise to ensure a safe and effective installation.

4. Does buitengevelisolatie require maintenance?

Buitengevelisolatie requires minimal maintenance, such as cleaning and inspection, to ensure its longevity and performance.

5. Can buitengevelisolatie be installed on all types of buildings?

Buitengevelisolatie can be installed on most types of buildings, including residential, commercial, and industrial buildings.


Buitengevelisolatie is an effective way to improve the energy efficiency and thermal performance of a building while providing additional benefits such as noise reduction and improved aesthetics. When considering buitengevelisolatie, it is important to choose the right insulation material and ensure that the installation process is carried out by a professional contractor. With proper maintenance and care, buitengevelisolatie can provide long-lasting benefits for your building and the environment.
