Have been looking at ways to insulate my garage door. I found several web sites that sell material to insulate residential garage doors. Some are foil-bubble pack-foil, others are foil-polyform-foil, still others are polystrene sheets with kerfs cut into the sheets to allow the polystyrene to bend and slid into place. Rather than buying these kits, I am thinking about buying polystrene sheets from a big box store and cutting to size and cutting kerfs to allow me to bend the sheets to slip into the openings on the inside of the garage door.

My question is what would you use to cut the kerfs that would make clean cuts without melting the foam or making a mess? Does anyone have experience cutting grooves into polystrene sheet goods?

a handsaw might work well

As I looked at the images of the kits, the kerf cuts look to be about 1/8” to 1/4” in width. So a handsaw would likely be too thin. This is only my guess.

A kerf cut does not have to be flat on the inside bottom to work. Cut in thin pie shapes with an Olfa knife (I use the large ones) or something like that. You can make a simple jig for a cutting guide that will give the same depth and width on each cut.

Hello there Dan Lyke, I believe using the multi-head mini split system will be better as also mentioned in assignment writing services uk I shall also recommend you the converter AC, it reduces the electric bills too. Well, I hope you get the best fit for you.
