Thermal and Sound Insulation

To meet today's regulations and build in accordance with current energy efficiency guidelines, all external constructions need to be thermally protected. Thermal insulation reduces heat losses in the winter as well as overheating in the summer and protects the load-bearing structure from external conditions and strong temperature strain.The thermally buildings are more enjoyable, its lifespan is extended and they contribute to environmental protection. Good knowledge of the thermal properties of building materials is one of the prerequisites for designing energy-efficient buildings. Thermal losses through the building element depend on the composition of the element, the orientation and the coefficient of thermal conductivity. The lower the coefficient of thermal conductivity, the thermal protection of the building is better.

To achieve good thermal protection of the external wall, the recommended coefficient of thermal  conductivity U = 0.35 W / m2K. This requires an average of 10 cm of stone wool rendered facade, or 8 cm of polystyrene, depending on the stated value of the thermal transferability of the material.

 

Types of thermal insulation

The stone wool is most applicable insulation material because of its good insulating properties asn well as the ability to diffuse vapor. The second most applicable materijal is ekspanded polystirene (EPS). There is a difference in investment between the two could range betseen 20-30% in favour of EPS, who is the by far the cheapest insulating materijal.

In the choice of materials for thermal protection, in addition to thermal conductivity, should take other material characteristics under account. This properties are fire resistance, water vapor, diffusion resistance, compressive strength, puncture, durability, moisture resistance etc., should be taken into account.

Next to our own production and sales of extruded polystyrene boards and stonewool materials, also the distribution of a wide variety of other insulation products is and will be a mainstay of the RBCS product portfolio.
