What is XPS?

It is a foam material with a homogenous cell structure, designed and used for thermal insulation.
Polystyrene, the rawmaterial of XPS is extruded in the desired thickness along the line during extrusion process. With the production carried out under continuous computer control, a stable cell structure which resembles a homogenous honeycomb is obtained.

Cells are connected to each other from their entire surfaces and air is trapped inside the cells. With the steady dry air. the most known and the best thermal insulation is provided. Surface of the material which comes out of the line is structured as smooth, squared, gritty or gritty-corrugated according to the requirements of the details.

The production technology enables a stable cell structure with an appearance of honeycomb. With the help of this structure, extruded Polystyrene materials (XPS) do not absorb water, are not affected by moisture and they have a certain superiority over other thermal insulation materials.

Thermal Insulation in Structures

Thermal insulation in buildings provide energy saving, reduce gas. soot and dust emission and realizes direct benefits for the environment. Wall, thermal bridge, floor and ceiling surface temperatures have significant effects on both internal comfort and structure shell. We need thermal insulation materials to protect our buildings against physical changes which occur in building components such as expansion and shrinkage due to different climate conditions and to provide buildings which are lasting and reliable.

As per European Standards, thermal comfort is defined as the difference between internal building temperature and internal wall surface temperature being 2-3°C at most. Condensation in thermal bridges, humid areas, mould formation and cracks can be prevented by using the correct insulation solution which suits to the project. Healthy and comfortable living can only be possible in areas which have appropriate temperature and humidity conditions. While insulating the building, due attention shall be paid to potential thermal bridges such as large surfaces like walls, roof and floor which are open to heat loss and also plinth wall, beams, lintel, radiator guards, parapets, reinforcement concrete columns, window ledges, supports between windows, outer wall corners, wall connection points. If thermal bridges are not insulated this may cause significant heat losses and also causes condensation, molding and formation of cracks.

Therefore, external thermal insulation is the healthiest application for structure health. In this application no heat bridges are allowed and building materials which form the building shell remain on the warm side. In the means of cost efficiency, thermal insulation is desirable for both ecologic and economic aspects and provides return of investment in a short time. For efficient thermal insulation in structures, thermal bridges, plinth level and face nonbearing walls shall be insulated with Teknopan completely and in a continuous manner.
