Founded by Jim Churchill who has a wealth of experience in the industry, Calendar began business in 1990.

We very quickly gained a reputation for reliable delivery coupled with a quality that satisfied some of the country’s busiest house builders.

Consistent growth gave the business the opportunity to invest in glass manufacture. In the last year Calendar HI has brought that glass manufacture on stream, has achieved the CE mark and BBA approval and enjoys key account status with world class manufacturer Saint Gobain.







Working from our 25000 sq ft of manufacturing space in Rotherham, we produce over 600 windows, doors and conservatories each week.

Our key benefits to builders and installers:

  • Quality profiles from Eurocell
  • Soft Coat Low e Glass technology from Saint-Gobain
  • Large manufacturing capacity
  • Own delivery fleet
  • Comprehensive product ranges
  • Ten Year Guarantee
  • Ten Day Delivery Promise!
