Hi. I am new to this forum. I am trying to design a system to secure a set
of double doors into an existing opening without actually drilling into the walls of the opening.

Fixings can’t be used for heritage reasons as the faces of the interior opening
(500mm deep) are clad in thick travetine Stone.

I am considering using a ply lining, perhaps double 16mm and then
‘clamp’ it to the structure through the use of timber that faces the
opening on both sides. Like a heavy duty architrave that fixes into
the edge of the double ply sheets.

The reason I am considering 16mm ply is that I understand its
available in a flexible variety. The top of the existing opening is
arched. So double standard ply to the vertical face and double
flexiply to the arch.

Veneer quality ply to match the hard wood edging pieces.

I could only use a glue if there was a system for removing the glue
at a later date without harming the stone cladding.

The double door frame (aluminium) would be screwed every 150mm to a depth of

I would be grateful for any advice. Is there a variety of ply in terms of its ‘gripability’
for the frame fixing?

Is there a glue that could be used to secure the ply sheets to the travatine stone facing
that can be safelty remove without damaging.

Would solid oak say 20mm x 100mm be appropriate for the ‘architrave’ ?

Perhaps there are reasons this design wouldn’t work.

An alternative solutions could be to ‘wedge’ a timber sub frame into an opening without using fixings?

Thank you for your attention.
