I am building some external doors, and on a US forum was advised
that in US they have a product that is Marine Ply with vertical
grooves .... so looks as aesthetically pleasing as T&G ... but has
dimensional stability of ply.

In US this is known as T-111 sheet. Or T-111 siding

Initially it had a rough-sawn, textured surface with vertical
grooves milled every 4 or 8 inches. Thickness ranged from 3/8 inch
to 3/4 inch. Usually fabricated from Douglas fir, but also in
redwood.

Anybody know of an equivalent product in UK ?

It may be worth chatting to Robbins. In their catalgue they have
something which may be similar (bottom right of page

Thanks ... I have dropped them a mail.


An alternative option would be to mill in longitudinal grooves into
Marine Ply sheet to simulate t&g ..... anybody done this ? ... is
this practical without compromising the waterproof properties of the
sheet.
It would be stained finish.

I've done similar with a router, v groove bit & a straightedge, but only on
smaller lengths e.g.2'. It looks pretty good as long as you keep the groove
dead straight.

You will need to do a bit of sanding afterwards & depending on the ply you
might reveal a different colour 'ply' at the base of the groove.
