Theta Insulation

Theta Insulation was founded by Ben Chapman. With over 17 years of experience in the thermal insulation industry, Ben worked on projects for construction and infrastructure companies, including Skanska, Kier, BAM, and Balfour Beatty, as well as many others.

Ben wanted to take what he had learnt and provide bespoke thermal insulation services to businesses across the region. Every organisation should be able to benefit from high-quality insulation that reduces carbon footprint and lowers energy bills.
