The Historical Development of EPS Insulation System

January 04 [Sun], 2015, 12:59
As we all know, EPS Partition Wall insulation systems (ETICS) or external insulation decoration system (EIFS) appeared in Europe in the early 1970s. In 1973 the first oil crisis in Germany, as well as the government's financial support for homeowners of this system has played a great role in promoting. From 1973 to 1993 in the Federal Republic of Germany about 300 * 10 square meters of building facades with the ETICS, thus saving more than 18 * 109L of heating oil.

ETICS make more stable temperature and humidity during the seasonal transition, it significantly improves the living comfort program. The system by reducing the temperature changes and moisture condensation facades, and significantly reduces the damage to buildings and reducing overall construction costs. Therefore, heat is not only a wise investment in new buildings, but also a useful measure of innovation, especially in the building facade must be refurbished occasions.

1970s first ETICS early arise in the construction site will be added to the emulsion adhesive cement. This composite material under the solid polystyrene foam board on the wall to be insulated. Products and processes using the same glass fiber mesh embedded in the reinforcement layer or insulating panel primer emulsion layer. In the early stage, most of the synthetic resin for the decorative coating on the undercoat layer.

For these reasons, as well as a two-component system shortcomings mentioned before, for ETICS, today the backbone polymer-modified cement mortar mix has replaced almost all other systems.

In practice, however, there has been a lot of problems when using EPS Wall partition system, especially in the field in the emulsion adhesive when mixed with cement. According to this process, cannot guarantee the same water-cement ratio, and mixing, and therefore cannot obtain a stable quality adhesives and undercoat, resulting in bond strength or flexible enough, resulting in product performance is not up, and may even damage the building facade surface. These drawbacks are also present in the two-component system, in which the system is added to the emulsion in the field of dry mix mortar.
