A general contractor was chosen by the American Society of Landscape Architects (ASLA) to provide grating for ASLA’s green roof at their headquarters in Washington D.C. The green roof is a part of the ASLA’s commitment to promote environmentally friendly designs to make green roofs a more widely accepted option for architects and contractors. The 3,000 square foot green roof will grow a variety of plants and also have a viewing area for the public. ASLA was looking for a walking surface that would allow plants to grow up and through the floor surface to maximize the roof space, allow people to walk on the space without damaging the plants, and for a product that would remain slip resistant against transpiration from the growing plants. The contractor contacted a grating manufacturer for a flooring solution.
