Home Insulating an Old House
Master Builder Matt Risinger joins builder friend Emily of Emerald and Laurel Design & Build to chat about some building science in a 1950's remodel and addition. Notice the original wood siding, a pier and beam foundation, solid pine studs, solid roof decking, and other 1950's standards in building. First, Risinger discusses how to maintain the integrity of the home and bring it up to code. As you'll see, they decided to install a brand new roof, which will help with waterproofing, so no more water can seep into the house. This is imperative since they are going with vaulted ceilings in the main living area.After the roof is complete, they're going to use closed cell foam on the roofline of the vaulted ceiling. The flat ceilings in the rest of the house allow for traditional blown-in insulation.On the opposite end of the home, you can see that the original hardwoods sit right on top of the shiplap floorboards. If budget allowed, they would create a conditioned crawl space. However, that's cost prohibitive for a project like this, so the next best option is to spray 2 of closed cell foam on the underside of the shiplap. This still provides additional insulation to keep the temperature-controlled air inside the home. Watch the full video to hear all of Risinger's insulation recommendations for this remodel.
