Salvaged insulation

I am frugal – really frugal – to the point where you can call me cheap. I have to be, if I want to get this project done within budget. One of my indulgences in frugality is executing some of the work myself. Not only does it save money, but it keeps me happy and I get to do a lot or research.

I just love these multidimensional aspects for their efficiencies. Surprised? Don’t be – I am German.

Here’s another one for you: I am frequently scouting Craigslist for materials that I may need or tools that would be handy. Lo and behold I came across a posting for a bunch of salvaged two inch rigid foam board insulation (the XPS type).

The sheets came from a roof tear down job and are perfect for the insulation under the new basement slab. Some sheets have corners missing or are not full sized, but I can cut them to fit.


I am very happy that I got them for less than half the retail price (frugality!), plus I keep this load out of the landfill, furthering our goal of responsible resource usage and construction waste management (CWM).

  1. Being able to recycle this used material and get it for half price is a win-win. It’s very cool when what is better for the budget is also more environmentally sound.

  2. Hi,
    I’m in Oregon,prepping to build a “tiny” house, primarily from found/salvaged/given materials. I was dumpster diving some foam sheets this evening, maybe good for insulation? When I came home to research it, I stumbled cross your site. Right up my alley, keep up the good work!
