Foam Insulation Inside Forms
Our old farm house, to the right in the photo above, is pink. It was cheap siding as Lloyd, the previous owner, had explained. Our tiny cottage was pink too for a while from the outer insulation around its thermal mass. Now it is grey and blends a bit better with the background. Stonework, even faux, looks better than pink.
The butcher shop is inside out right now. We’re building a large mold into which we’ll pour the building. As part of that mold we have insulation. We’re insulating the forms so that the concrete will be instantly and automatically insulated, tightly binding to the foam. It’s a technique I developed about 20 years ago and have used since then for a variety of projects. Simple and effective with the added benefit that the forms peel easily and the concrete is insulated eliminating the need to wet it or warm it – key in our typical cold weather pours.
Washers Holding Foam in Place
To hold the foam in place we use large washers made of recycled cream cheese container lids and a sheetrock screw. This matrix of attachments will help to bind the whole together as well once the concrete cures.
Our butcher shop has a lot of insulation in it. We spend the money now to save it for decades later on our energy bill.
