Concrete does not have a high thermal conductivity, which means it will take quite a long time to heat up and to cool down, creating an insulating effect and helping to balance temperature fluctuations. Using your existing slab and not adding a flooring that would need to be removed or replaced in the future is a sustainable solution because it not only decreases material use but also the need for replacement – helping both the environment and your building maintenance costs. Polished concrete can also be sealed with low VOC (volatile organic compounds) to further decrease any environmental impact. With a polished concrete floor, there is also increased light reflectivity, projecting a professional image and saving on lighting costs. Polished concrete will add more light to the area without the cost of adding fixtures by reflecting light from windows and current lights. During installation, dry, dust-controlled equipment filters and vacuums filter out 99.9% of all airborne dust. With no adhesives or coatings applied, and use of existing building substrate, it is very helpful in LEED projects.
