The Wilson family's deep energy retrofit (DER) continues . . . with spring in the air, half-round faux copper gutters from GutterSupply.com and SmartSide trim & siding from LP Building Products dress up and protect the exterior. Then, plastic studs from EcoStud and more FoamItGreen spray foam insulation help to tackle the basement, bringing it into the thermal envelope of the house. Finally, an energy recovery ventilator (ERV) addresses the indoor air quality (IAQ) of the home to make it a healthier place to live. Which leaves us wondering, IMHO, the ERV fixes the IAQ in our DER. LOL! Check out all the acronyms, euphemisms, and double entendres today at TGHE . . .
