Patent Glazing Bars

Alton Towers

This prestigious contract was successfully completed by Howells Patent Glazing Ltd in April 2011. Our customer was Seddon Builders of Stoke. 

The works involved the construction of an all new orangery roof to Alton Towers Castle, which forms part of the renowned theme park. 

The glazing contract took place over 4 months, with a value of £ 110,000.00, and a resolute completion date to align with the park season opening. 

The glazing bar was an adaptation of our best selling HGR 1 rafter bar, adapted to suit the narrow timber rafters, which were considered to be an important part of the original design and appearance of the building.

An exciting and challenging contract which, we hope you will agree, looks eye-catching, and is a good representation of bespoke work carried out to a high standard

Aluminium powder coated HG57 Medium Duty glazing bar system


This project was a combination of shaped roof and vertical glazing, fitting to a steel sub-frame.  The project involved many complicated details that we resolved through our technical department.  Due to the intricate and complex shape, it was necessary to install the framework and take actual glass sizes.Whilst this necessary sequencing ensured a correct fit, it put a lot of pressure on the very tight programme.


A handsome coffee lounge was the result of all the hard work and also the canopy adjacent to the main feature.

Leeds City College

Leeds City College had a particular problem with a 40 year old patent glazing system with single glazing. It had been constructed using steel bars which were not thermally efficient. The system lost a lot of heat and accumulated condensation daily as a result of no ventilation. There was also asbestos in the design.

We attended the site and supplied an all new aluminium thermally enhanced patent glazing system using our self supported HG2/3 profiles. We arranged for the main contractor to remove the asbestos as we could not carry this out at the time. However, we now have certification to provide this service. We installed the new double glazing using energy enhanced glass on the inner pane which included a thermal coating. The glass was provided by Pilkington, a well known manufacturer using their K Range Thermes 1.  This increased the overall heat efficiency of the room. To help with the air circulation problem, we also installed thirty electrically operated opening lights that were additionally linked to the building management system.
