Aluminum windows & bi folds

[liamgt4]

Hi,

Just submitted plans for a large extension, hopefully doubling the size of our 60's bungalow. (Will post more details later)

The plan is to have 3 sets of bi folds across the back of the house and replace the old uPVC windows.

Have decided we want aluminum.

There are so many companys that supply and fit these type of windows and bi folds but don't know which way to turn.

Has anyone had these fitted? Who by and are they good quality.

Only had one quote from Everest that was massive, but i know they have a good reputation.

Any advice would be great.

Cheers
