Hello,

I am looking to box around a boiler. I was going to use melamine faced
chipboard, though I have read here of melamine faced mdf. No-one
locally has heard of the latter!

Regarding the chipboard variety, I need something 3' wide.
Unfortunately the "sheds" only sell up to 2'. I have asked the local
timber merchants: one does not do it at all and the other only goes up
to 2'.

Help! Where can I get it from or what do you recommend I do as an
alternative?

I have read here about people joining chipboard with those "white
blocks". Will that be sufficient? The blocks don't look very big to
me, or is it better to put a frame or some form of support underneath?

Thanks.
