About Us

We are a "SUPPLY ONLY" manufacturing company and do not compete with any retail suppliers whatsoever. The majority of our customers are trade, however we are happy to supply to the ever-growing self-build and DIY market. If you want one of our products fitted then can help find you a supply and fit company in your area from our extensive (4500+) customer base.

The company is a family run business and was established in 1985, employing approximately 100 staff.

Due to continued strong growth, the company has expanded its production lines to accommodate customer demands and to reduce lead times. Duration Windows aims to deliver any order in 2-3 weeks from the date of the customers order acknowledgement, regardless of the size of the order. The manufacturing of all of our products has been separated into 9 individual departments specialising on sole products to achieve a higher quality product and to maximise efficiency.

The success of Duration Windows is based on versatility, innovation and support.

We supply all of our products across the country on a day to day basis with a fleet of ten vehicles. We deliver straight to the customers door or to specified delivery addresses.

We are your one stop supplier, service does matter and you cannot afford to let price be your only concern !
