Good thermal insulation performance. The thermal conductivity is about 10%, which is better than polystyrene board. It is a good material for building insulation.
>Good waterproof performance. The foam holes are closed, with a closing rate of %, and rainwater will not seep through the holes.
>Due to on-site spraying, an overall waterproof layer is formed with no seams, which is unmatched by any polymer membrane, reducing the amount of maintenance work.
>Good bonding performance. It can be bonded very firmly to wood, metal, masonry, glass and other materials, and is not afraid of being lifted up by strong winds.
>It is suitable for new roofs or old roof repairs, especially for old roof repairs. It is not necessary to remove the original waterproof layer and insulation layer. You only need to remove the gray sand debris on the surface before spraying.
>Construction is simple and fast. Each job can spray more square meters per day, which is conducive to progress.
>The closing structure is simple. Spray foaming polyurethane to close the ends, no special treatment is required, which is greatly simplified. If roll material is used, a groove must be left at the parapet. If the groove cannot be left for the closing head, a flat iron sealing nail must be used to close the head and caulking paste must be applied.
>Good economic benefits. If the insulation layer and waterproof layer are separated, not only the cost will be high, but also the construction period will be long, while foamed polyurethane will survive at one time.
>Good aging resistance. According to foreign engineering summaries and research tests, the aging resistance can last up to 10 years.
>
>Fast. After foaming, it is durable and can significantly extend its service life.
