    Hi guys.

    Just wondering what everybody else uses to cut PU foam slab. I am cutting 8 foot lengths for reinforcement. They are approx 6" wide x 4" tall with mitred corners.

    I use a bandsaw . Cuts like butter. I am cutting alot of these.

    Just wondering if this was the normal way of cutting foam slab.?

    Thanks in advance. Neville.

    I've used a makeshift wooden setup with a mains transformer and a piece of metal wire with high electrical resistance, like nickel. A spring on one side keeps the wire taut when it get hot and stretches.
    Slower than a bandsaw but not so messy.
