How to attach PVC fascias and soffits ?

[Pickup]

Hi,

I'm considering replacing the wooden fascias, soffits and bargeboards on the house with white uPVC (thinking about my old age and want a low maintenance solution.)

Most of the houses in this area of town (Aberdeen) have been done and nearly all of them seem to have been attached with nails (plastic headed for PVC).

The ones that don't appear to have been nailed (ie no visible marks / nails on the fascia board) look a lot better.

Is there a way in which the boards can be secured without nailing?
Should the PVC be the same thickness (15mm) as the wood it's replacing?
Should joints be glued and capped or just capped?

Thanks

F

Replacement facing is normally 18-22mm and fixed with pollytop annular nails.
The nails are probably hidden behind the gutter.

the soffit plate is fixed with a smaller guage pollytop which is barely visible from ground level.

There is a variety of joints corner internal, external, butt joints etc for both fascia and soffit which slide into place and either siliconed and pinned or friction fitted.

Just nail towards the top of the rafter if you don't want the heads to be seen. Polypin all your corners and joints, never glue or silicone
