How to convert the thickness of geotextile and gram weight, can non-woven fabric be cold insulation? | JINHAOCHENG

How much is the gram weight corresponding to the thickness of geotextile?

The weight of geotextile varies from 100g to 1000g per square meter. Since it is non-woven fabric made by repeated needling, it is impossible to judge how thick it is by hand touch, and special non-woven fabric thickness measuring instrument must be used to measure it.

So 100 grams of heavy non-woven cloth thickness how to calculate?

The answer is incalculable.We can only according to the geotextile technical indicators to determine its g, 100 g non-woven fabrics and short wire cloth and filament fabric, although both are 100 grams, but the thickness is different, the thickness of the short wire cloth 100 g in 0.9 mm (millimeter), whereas the filament in the 0.8 mm, of course, there will be 2% to 3% error exists, because different types of equipment and technology operations are distinct, so can't avoid the existence of the error.

Geotextile Felt

Can nonwoven geotextiles keep warm?

Because non-woven fabric is made of high strength and anti-aging polyester fiber or polypropylene and polyester chips as raw materials through special processing, so it has a good corrosion resistance, acid and alkali resistance, fracture strength and frost thawing resistance.

For example, in the construction of the greenhouse cold insulation system, non-woven cloth can completely replace the use of felt, laid simple, save time and effort;In terms of roof insulation, the traditional facade insulation system is to build a structural layer after the lowest layer is tamped down, then pour aerated concrete on the structural layer, and then lay an asbestos insulation layer, and then lay a waterproof layer and non-woven cloth on the top layer.

Such meeting causes cloth to be exposed, below the long-term illuminate of ultraviolet ray, shortened its life;With the progress of science and technology, people are constantly innovation, invented a new roof insulation structure: the way of inversion insulation system, this method is and traditional way of is, in turn, will be the top of the waterproof layer and the geotextile laid in the foam asbestos insulation layer below, make the cloth not exposed deep underground, thus greatly extend the service life and make the insulation main body is more stable, reliable, and saves the cost of the engineering cost.
