Rubber insulation cotton is a commonly used building insulation material, which can not only be used in indoor HVAC pipes, floors, walls, etc., but also can be used outdoors. Whether rubber insulation cotton is afraid of being rained on depends on its waterproof performance to a large extent.

Rubber and plastic insulation foam made of rubber and plastic closed cell structure material, this structure is different from the open cell fiber structure so easy to absorb water, even if the surface is damaged, closed cell structure can prevent water vapor intrusion. In addition, the surface of the rubber insulation cotton is covered with a waterproof film or coating, which has good moisture-proof performance. Therefore, under normal circumstances, the rubber and plastic insulation board will not be directly soaked by rain and hygroscopic. It can effectively prevent water from penetrating into the interior of the building structure, thus maintaining the thermal insulation effect of the building.

Although rubber insulation cotton waterproof performance is excellent, but the rain has strong corrosion, especially in heavy industry areas. Therefore, in a short period of time, rubber insulation cotton is not afraid of being rained on, but long-term rain will accelerate the aging of rubber insulation cotton. When rubber insulation foam is used outdoors, try to protect it.

When using rubber insulation foam, try to avoid long-term exposure to rain. If it is unavoidable, appropriate waterproof measures should be taken, such as installing waterproof layers or using waterproof materials for protection. At the same time, standards are also critical for construction. It is best to do regular inspection and maintenance, and timely deal with any existing problems, such as damaged waterproof layers, cracks or damaged insulation boards.

Rubber insulation cotton has excellent waterproof and moisture-proof performance, so it is not afraid of rain, but long-term rain may lead to its performance decline or other problems, so it needs to be protected.
