First of all, when using the rock wool board, we must be careful to guard against Rain Water and not to work on rainy days, which is very important. Moreover, it is necessary to consider whether it is used for cold or heat preservation. If it is assumed that it is cold, it must be moistureproof. Only in this way can we achieve a good effect.

The air quality of the confined space in the car is more related to our daily health. The VOC in the car mainly comes from carpets, dashboard plastic parts, roof blankets, seats and other decorative glue. The plastics, rubber parts, fabrics, paint materials, thermal insulation materials, adhesives and other materials used in the car contain organic solvents, additives and auxiliaries, which will also increase the VOC value inside the car. This does not include the large VOC manufacturers such as floor mats, trunk mats and seat covers installed in the rear market.
