Kitsons, the new name for SIG Technical Insulation

With a history dating back to the 1800s, the Kitsons name is synonymous with thermal insulation.

In the Victorian era, things were a bit different. We started life as a local specialist and slowly built a reputation for helping tradesmen overcome hardy challenges.

Now one of the key distributors in the technical insulation industry, we offer our expertise and range of products in Industrial, HVAC, High Temperature, and Fire Protection at scale – up and down the nation, under the SIG name.

The market has changed, and now it’s time for us to evolve too.

The Kitsons name has always been one you can trust. It’s always represented a promise – a promise for an extensive range of high-quality technical materials, impartial advice from experts in their field, and project-saving solutions for even the most persistent of on-site challenges.

With such recognition in the market, what other name would we choose? Kitsons, the new name for SIG Technical Insulation
