I have had a bi-fold door, and an additional window from Kloeber, the bi-fold is fantastic installed brilliantly and they have been very accommodating due to delays in our build. I intend to get all the windows and doors replaced in time, but thus far i have been impressed, only reason it isn't 5 stars is the delivery charge is very steep on an already expensive product given we are less than 10 miles away.
