ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

Rigid foam board is a lightweight, high-strength building material widely used in various fields. Its primary applications include:

Building insulation: Rigid foam boards (such as polystyrene or polyurethane foam boards) offer excellent thermal insulation properties, commonly used as insulation layers for walls, roofs, and floors to effectively reduce energy consumption and provide a warmer environment.
Упаковочные материалы: Due to its cushioning and compression resistance, it is commonly used for transport packaging of electronic products, furniture, and other items to protect them from damage.
Decoration and modeling: In interior design or stage scenery, rigid foam board is easy to cut and carve, making it suitable for creating decorative panels or models.
Логистика холодных цепей: Used in refrigerated boxes or insulated containers to maintain a low-temperature environment. Used for food and medicine transportation.
Waterproof and sound insulation: Some rigid foam boards have waterproof and sound-absorbing functions and are commonly used in recording studios and street-facing residences.

Rigid foam boards are an ideal choice for construction, packaging, and creative design due to their versatility, light weight, and cost-effectiveness.

The R-value (thermal resistance value) of rigid foam board is a key indicator of its thermal insulation performance, and the specific value varies depending on the type and thickness of the material. The following are the R-value ranges for common rigid foam boards (including PET and PVC):

Extruded polystyrene (XPS): R-value of approximately 5.0 per inch, highly water resistant, suitable for damp environments such as basements.
Полиуретан (PU): Approximately 6.5 R-value per inch, offering both waterproofing and sound insulation properties, with excellent thermal insulation performance.
PET foam board: Approximately 4.0-4.5 R-value per inch, environmentally friendly and recyclable, commonly used in lightweight structures and packaging.
PVC foam board: R-value approximately 3.5–4.0 per inch, corrosion-resistant and easy to process, suitable for signage and decoration.

The higher the R-value, the better the insulation performance. Selection should be based on application requirements, climate conditions, and budget. For example, polyurethane boards are recommended for cold regions, XPS for humid environments, while PET and PVC are more suitable for lightweight or decorative applications. Proper sealing is essential during installation to optimize insulation performance.
