Benefits

Comparing stormwater management solutions

Siplast Stormwater Management Solutions include Purple Roof Systems™, Vegetated Blue Roof Detention, Blue Green Roof Retention, and Paver Blue Roof systems.

1 Low sloped roofs can diminish the efficiency of Siplast water retention/detention systems as compared to roofs with no slope. For example 1/4" per 1" slope reduces the storage capacity of a blue roof by 66%.

2 Height is estimated based on typical assemblies and dependent on stormwater management requirements.

3 Weight is estimated based on typical assemblies and dependent on stormwater management requirements. Each system will different depending upon the specific assembly and climatic conditions of the building location. Always consult a design professional to ensure that the building structure can withstand the actual anticipated weight of the full saturated at a given location.
