We may not be very familiar with PVC foam boards, which are used in industries such as commercial decorative shelves, advertising signs, exhibition boards, and exterior wall panels. What are the characteristics of its widespread application?
1. Good insulation, waterproofing, bonding performance, aging resistance, and easy and fast cutting construction.
2. Due to on-site spraying, an overall waterproof layer is formed without joints, which is beyond the reach of any polymer roll material, reducing maintenance workload.
3. Good adhesion performance. It can bond very firmly with materials such as wood, metal, masonry, glass, and is not afraid of being exposed by strong winds.
4. It is suitable for repairing new or old roofs, especially for repairing old roofs. It is not necessary to remove the original waterproof and insulation layers, but only to remove the dust and sand debris on the surface before spraying.
5. The ending structure is simple. Spraying foam polyurethane ends without special treatment, greatly simplifying. If coiled material is used, a groove shall be reserved at the parapet, and the end shall be in the groove; If grooves cannot be left, flat iron sealing nails should be used to close the head, and caulking paste should also be applied.
6. Good economic benefits. If the insulation layer and waterproof layer are separated, not only will the cost be high, but the construction period will be long, and the foam polyurethane will survive in one go.
