OT: Help please: cutting styrofoam sheets

Zz Yzx · 2010-07-03T23:09:12+00:00

My shop has a steel roll-up "garage" door that faces a blistering sunfor several hrs/day. I'm determined to insulate it. The easiest wayI see is to slap some styrofoam shhet insulation onto it. I can get 4' X 8' sheets at Big-Box for a good-enouhg price, but needto trim the sheets down to ~ 44" X 22" to fit into the recesses of thedoor.What's the best way to cut 1-1/2" or 2" styrofoam sheets? I don'thave a "hot wire" cutting tool.Thanks a heap,--Zz

Another use for your Fein, Bosch, Dremel or Harbor Freight Multi Tool

It makes a mess, but any old wood saw will make a decent cut. I recently did some on my table saw and it worked fine. In the past I used a jab saw or a hand saw. More specific to your application... I recently partially disassembled a damaged aluminum boat and found porous plant foam between the ribs. I ripped exact fitting pieces on my table saw. Then I took a wire brush to the aluminum and got a good rough surface. Then super grip construction adhesive and a press fit.

I've used a saber saw with whatever wood blade I had in it and it works great w/o much of a mess. Last time I used a mini sawzall with the same blade, cuts like air. Using a metal blade would likely leave zero mess.
