Since 1977, Topline has had to rapidly adapt to keep up with a constantly developing industry...

Topline Glazing Ltd. was established in 1977.Run by husband and wife team Neil and Valerie Joslin, they began to manufacture sealed units out of a small premises on Ilton Business Park. After 23 successful years, in 2000, the company was sold to long-term employee Joanne and her husband Graham. Re-named Topline Glass and Glazing Ltd, the company began supplying a wider range of glass products to a larger customer base, meaning more employees, more delivery vehicles, and more up-to-date machinery was desperately needed.

To accommodate this rapidly expanding business, the decision was made to move to a larger, purpose-built factory. In 2003, Topline re-located to The Conquest Business Park, just outside of Ilton. With more space and facilties, Topline continued to grow enabling them to venture into all areas of glass and glazing.

After just 2 years in the new building, Topline had become one of the south west’s largest sealed unit manufacturers, and had already out-grown the new factory. So in 2005, they moved again to a neighbouring plot on the same business park. This building was twice the size of the previous, and was fully fitted out with the most up-to-date machine technology, including a 3.2 tonne over-head glass lifting crane.

In 2009 Topline grew further with the addition of an extension to prepare and store the hundreds of units we process each day. Currently, Topline employs over 30 people and continues to grow.
