How Doorwin defines custom fit

Custom fit (window and door fitting manufacturer) means that your window or door will be exactly sized to fit your opening. This can be achieved by ordering a custom size, or by using one of our standard sizes which may be modified slightly to meet your needs

2. Is there a difference between custom fit and standard sizes
