Conservatory UPVC Frames

Do I need to have the UPVC double glazed window frames assessed (condition, weight loadings etc) when replacing the existing Polycarbonate conservatory roof system with a Double Glazed Glass roof system

"Yes you do need to check the frames and sills are reinforced by a competantant installer.
And also weight of the new roof would need to be considered before instalation .
A competent installer can do this for you ."

"As long as you have load bearing adjustable jacks below any corner posts then this would be suitable. These are designed to transfer any weight that's carried above directly through your reinforced corner posts into stable ground below."

"It would be better to have them assessed. As it is not known how many mullions are in the existing. If you are having thoughts of changing to keep conservatory warm in winter and cool in summer think again it won’t work. It would be better to explore having a complete new fully insulated light weight tile roof."

"It’s best to know that the windows are reinforced.
To see if the windows are made as one or coupled together
Some conservatory installers use corner posts that go through the sill onto the brickwork of the dwarf wall as opposed to just sitting in a hollow sill.
I guess it’s down to the installers competence and how they are looking to not contradict any building regulations that may or may not have been put in place.
We would assess and give our recommendation free of charge.
