SUSTAINABLE HOUSING INSIGHT Healthy Indoor Environment Carpet collects dust and dirt and can be unsuitable for people with respiratory ailments. Solid-surface finishes, such as hardwood, ceramic and vinyl are easy to clean and are suitable for most people with environmental sensitivities. Wood and engineered wood flooring are durable and easy to clean, and are less likely to retain dust and allergens than carpet. Use prefinished flooring or water-based floor varnish for hardwood flooring. Environmental Responsibility Select adhesives that are compatible with the materials and have low emissions. Bamboo and cork flooring are natural alternatives to wood, vinyl composite tile and ceramic tile. Affordability Floors are high-use surfaces and using better quality flooring materials may result in lower costs over time.
