If you add insulation to your walls but you don’t pay attention to sealing them well, you’re asking for trouble. Make sure the walls don’t get wet from water leaks or air leaks! Building a better seal for airtightness and weather resistance doesn’t have to cost much. We’re talking about basics here: keep liquid water out by using basic flashing techniques and attention to detail. Then seal the air leaks! They carry moisture too. Make sure you provide good ventilation, then seal up every leak you can. Seal Tight and Ventilate Right. Keep out bugs, keep out smells, help control humidity, and save energy too. You’ll also build a more durable building!
