Kae makes the first attempt at insulating the interior of the trailer, using two varieties of spray foam insulation, fiberglass insulation batts, and a poly vapor barrier (see below for links to specific products used). Working solo definitely has its drawbacks, but some significant progress was made nonetheless towards the ultimate goal of a cozy, insulated space!
Update: Reid thinks that Kae did a decent enough job that we don’t need to start over…which is good ; )
Here are the products used in the insulating process (spray foam and poly vapor barrier purchased at Home Depot; EcoBatt insulation found (deeply discounted) from a local who had extra bags lying around):
Great Stuff Window & Door Insulating Foam Sealant: Specifically designed to be low-expansion, minimizing the chances of warping or bowing windows and doors.
Knauf EcoBatt Insulation (R19): Touted for being low-dust and easy to cut, Kae can verify that this insulation was super easy to work with, and we were psyched to incorporate “the most sustainable and environmentally responsible insulation ever made”!
HDX Clear 3.5 mil Plastic Sheeting: Turns out that a vapor barrier is required by building code in almost every state…and since we have no plans to move to Florida, we decided it would be best to comply. These rolls of plastic sheeting come in a variety of thicknesses, but the Home Depot experts said 3.5 mil was the way to go (the thicker rolls tend to be used for other purposes, such as under-floor moisture barriers, where added durability is desirable).
