How a roof is helping to reduce air pollution in Vancouver

This reroofing project for a low-income apartment complex in downtown Vancouver is helping reduce atmospheric pollution. The roof is a two-ply Siplast SBS-modified bitumen system featuring a cap sheet surfaced with Eco-Activ depolluting Noxite® granules. As well as meeting the city's initiative to reduce environmental impacts, the use of torch-grade material to avoid hot asphalt fumes minimized disruption to tenants.
