As we learn more about building science homes are being built tighter through good construction details. This is a GOOD thing. The new worry is that many products used in homes off gas chemicals known in the industry at Volatile Organic Compounds (VOC’s). These chemicals have adverse short and long term health impacts on the people living in your home. While we are still learning a lot about what chemicals are safe – if any – you should be sure to use those proven products that are available with a NO-VOC option. Paints, caulks, adhesives, stains, and joint compounds are just the starting point. Discuss with your architect the options, which products seem to be working and which have durability issues, and make wise decisions for your family. Product selection along with a appropriate ventilation system in your home will lead to better health for everyone living there.
