Duration Windows Showrooms

Duration Windows is a supply only manufacturing company that does not compete with any retail companies whatsoever. The company is a family run business and was established in 1985, and employs approximately 150 staff. We aim to deliver any order of standard colours in 2-3 weeks from the date of the customers sign off of the order acknowledgement, regardless of the size of the order.
