An easier way for construction and more cost-efficient solution, compared to external thermal insulation systems, is the thermal insulation panels installation with glued drywall on the inner side of the walls. This contributes to the desired energy saving and the thermal comfort of the building in fast, clean and low-cost way.

Styropan produces waterproof composite panels (consisting of gypsum boards in various thicknesses and a thermal insulation panel adhered) that can be easily and quickly installed on the inner side of walls. After their installation, you just must apply the proper type of putty and fiberglass tapes in the joints between the gypsum boards and the surfaces will be ready for painting.

The insulating material used is either graphite expanded polystyrene STYROPAN GRAPHITE EPS, or extruded polystyrene STYROPAN XPS. Due to the very low thermal conductivity coefficient (λ) of these two materials compared to others, the least material thickness possible is required to achieve the desired thermal insulation, thus saving space.

In the case of the internal thermal insulation, since the insulating material is on the inner side of the wall, the space reaches the desired temperature very quickly since the heating/cooling system commences its operation. However, for the same reason, after it shuts off, the area will lose its temperature level much quicker as we do not take advantage of the shells thermal capacity (the ability to radiate the heat in the interior space that it has absorbed through radiation).

• It is usually preferred for non-continuous use buildings such as offices, commercial stores, vacation residences, public services, schools, event halls, theaters, cinemas etc. where the top priority is to achieve the desired temperature level without needing to maintain it for long periods of time after the heating/cooling systems shut off.
• It is an easier, more cost-efficient and faster application as no scaffoldings are needed, contrary to the case of external thermal insulation nor any fiberglass base coat or any kind of special coating; just putty the drywall and paint it.
• Sometimes it is the only possible solution for old or listed buildings where their façade must not be aesthetically altered.
