Protects the rising waterproof layer and preserves the asset value of the building.

In office buildings, protecting the rooftop waterproofing is crucial for maintaining the long-term asset value of the structure.

Paraboard helps protect the waterproofing layer from these factors and contributes to extending the lifespan of the building. 【Usage Scenarios】 - Waterproof protection for rooftop vertical sections - Protection of waterproofing layers during new construction and renovations 【Benefits of Implementation】 - Suppresses the deterioration of the waterproofing layer and reduces maintenance costs - Maintains the asset value of the building - Preserves the aesthetic appeal of the building
