My daughter had all the windows and 2 comopsite doors and a patio door fitted .she had nothing but trouble composite doors leaking and badly fitted patio door wont open when the sun shines on it due to bowing.
The first patio door was replaced by coral because it was bowed
The new door has much the same problems plus got very little insulation in the cavity none at all on the top edge .
Coral say they dont know what they find untill they take the unit out with this been a replacement you would think that they would of sugested cavity closers but no .
They aranged an independant inspetion who found fault with the fitting low care an skill and this was proved in court
They also didnt fit cavity closers these should be fitted if you read building regs this is just a few of the problems .they came to try to fix the problems on multiple visits but never solved the problems of poor fitting
They say its due to conditions in the house i have since removed trims around windows and door and i was shocked to see how bad the expanding foam was very little in there none at all in some areas screws not into stone work and only into the cavity shocki g work from the fitters if you do use coral be sure to check before they stick the plastic trim around
