Why acrylic edge strip will be called 3D edge strip
Exterior insulation system (ETICS) or an external insulation decoration system (EIFS) in early 1970s appeared in europe. The first oil crisis in Germany in 1973, and the government to private saving the financial support of this system have played a significant role in promoting. From 1973 to 1993 in Federal Republic of Germany about 300*10 square meters of the building facade is equipped with ETICS, so as to save more than 18*109L of heating oil.
ETICS temperature and humidity is more stable when the season changes, so significantly improved the living comfort program. The building of the system by reducing the temperature change and the condensation of moisture, reduce damage to buildings and reduce the overall cost of construction.Therefore, the insulation is not only wise investment in new buildings, but also a good innovation measures, especially in the building facade to be renovated.
The first ETICS appeared in the early 1970s, is in the construction site will cement adding emulsion adhesive. This composite material will be foamed polystyrene solid to heat insulation wall. Using the same products and procedures will be embedded in the glass fiber mesh reinforced layer or insulating board bottom coating emulsion layer. In the early days, most of the synthetic resin used for coating bottom decorative coating.
However, in practice, there are many problems when using this system, especially in the emulsion adhesive when mixed with cement in the field. In this process, can not guarantee the same water cement ratio, and mixed evenly, thus unable to obtain stable quality adhesive and bottom coating, resulting in bond strength or flexibility is not enough, resulting in product performance standards, and may even damage the facade. These shortcomings also exist in the two-component system, emulsion in the system in the field is added to the dry mixing mortar.
For these reasons, as well as the previously mentioned two-component system shortcomings, for ETICS, this polymer modified cement based mortar has almost replaced all other systems.
