Anyone made their own rooflight openers?

[Beau]

We have some conservation rooflights which the paint is starting to fail on. Like these https://www.therooflightcompany.co.uk/all-products/conservation/

 

To be frank the the rooflights are pretty poor thermally. Steel frames which get condensate which drips in to the room. I was a furniture maker in a previous life and was considering making some wooden openers (the frame set into the roof looks OK). Was thinking of laminating the frames for stability and sealing them in epoxy. Also not sure if high spec DG or triple glazing would be more sensible. 

 

Any thoughts on the matter would be much appreciated
