The plastic used in such curtains is usually PVC and each is made to measure to fit each door perfectly. Exact sizing is important to produce efficient savings, it is essential that the curtain does not touch the floor. A 1mm-2mm clearance is ideal in order to prevent the miss shaping of the entire curtain and maintain its sealing ability. Over time, the PVC strips will stretch and you may find they are touching the floor. If this happens, trim the bottom off all PVC strips to achieve the original 1mm-2mm clearance, use a ruler and marker to match the trim on each strip before cutting to ensure a nice even line.
The curtains can be fitted in a variety of ways to suit a number of different situations. You might want them to be easily removed for certain circumstances, or have them installed as a permanent fixture. Your installer will be able to work out the best mounting system to suit your needs and also offer you a range of colors such as yellow, blue, gold, and several others including translucent shades all in a variety of thicknesses and flexibility. Thicknesses range from 1mm to 2, 3, 4, and 5mm. Three millimeters is the most common choice and is ideal for large traffic doorways, providing easy access while offering good sealing and visibility abilities. If you have two doorways access, it is best to have one as a solid closed door to avoid draught and to maximize your energy-saving efforts. If that’s not possible, you can choose a thicker curtain and step up to a more rigid type, four or even five-millimeters thickness for the doorway less utilized.
The best option is still the one where the door is closed and no curtains are used, we come to this conclusion due to the chemicals and energy involved in the PVC production and later disposal, as we move forward we all become smarter and more reasonable in protecting our environment we are confident that the new generation can and will be quiet easily adapt to having to open a door to enter a shop to get their favorite wanted goods. This is based on a trend adopted by all shops and public access buildings that heat or cool with Air-conditioning systems. If you decide to adopt this new way, keep the doors closed and implement symbol No.L5 Air-conditioned premises and print the PDF available.
Example: Room/shop 10m x 10m x 2.5m in height well-insulated no additional heat load requires 12 kW Cooling/Heating capacity = 4.0 kWh compressor power consumption. E.g. With the door open and with door curtains fitted can reduce the A/C running time by two hours.
