How does insulation work?
External wall insulation can be thought of as a protective cover for the house that provides comfort and warmth. The external wall insulation system consists of several layers of components, the core of which is the insulation board, plus a reinforcing layer and a decorative top coat.
The right insulation for your home
The insulation boards will be fixed with adhesive and mechanical fixings into the facade. But not all systems are the same; they are differentiated by the type of insulation.
The most common types of Insulation are:
- Polystyrene rigid-foam panels (EPS)
- Mineral wool panels
Which type of insulation is right for you depends on several factors - such as the height of the building, the facade surface, the coating, the space available and of course personal preference. Polystyrene boards are more cost-effective than mineral wool slabs, but mineral wool slabs have a better fire resistance and therefore are preferable in certain circumstances.
Protection against weather: the reinforcing layer
The reinforcing layer is applied to the insulation board. It is made from a high-quality filler incorporating fibre glass. Thus, the reinforcement layer protects the insulation from mechanical damage and takes out the stress caused on the surface by weather conditions and temperature fluctuations.
Practical and beautiful: the final layer
The final coat of an external wall insulation composite system consists of a structural render that can be produced to the desired colour and also painted. The final coating may also consist of brick slips.
External wall insulation application is a job for the professional installer
Application of a external wall insulation systems calls for professional work. It should not be undertaken without technical knowledge of the system to ensure the installed system works effectively.
