Thermal Secondary Glazing
Improve thermal insulation of existing windows by up to 65%
Solutions to fit any size and shape of window
Improve your commercial EPC rating
As an extra layer of insulation, secondary glazing helps to minimise heat loss and heat gain through windows, resulting in reduced energy consumption and increased thermal comfort.
The thermal benefits of secondary glazing in commercial premises, include better insulation, with regulated and stable temperatures throughout rooms.

Here are just a few ways we can City insulation can help
Shielding against the heat
Secondary glazing acts as a protective shield against heat transfer by adding an extra layer of insulation to existing windows. The air gap between the original window and the specially manufactured glass in the secondary glazing creates a buffer zone that reduces heat transfer through conduction and convection. This prevents heat loss during colder months and heat gain during warmer periods, improving the overall thermal performance of the building.
Keeping it toasty inside
One of the primary benefits of secondary glazing is its ability to minimise heat loss through windows. As an additional barrier, secondary glazing prevents warm air from escaping and cold air from entering a commercial premises. That means reduced reliance on heating systems, lower energy consumption, and cost savings on heating bills. A more stable indoor temperature gives staff a comfortable work environment right throughout the year.
Reflecting the sun’s heat
Secondary glazing plays a significant role in reducing solar heat gain. When combined with low-emissivity glass coatings or solar control films, it helps to reflect a significant portion of the sun’s heat, preventing it from entering the building. This reduces the need for air conditioning and mechanical cooling systems, resulting in energy savings and a reduced environmental impact.
City Insultation’s secondary glazing expertise brings a range of thermal benefits for both private and public organisations. Our secondary glazing enhances insulation, reduces heat loss and heat gain, improves comfort, and controls condensation. By investing in secondary glazing you can improve energy efficiency and reduce costs, while creating a comfortable and sustainable working environment for employees.

Review for City Insulations
★★★★★
I highly recommend City Insulations! They recently completed insulation work in my daughter’s bedroom to help manage her sound sensitivity, and the results have been fantastic. The team was professional, efficient, and exceptionally tidy throughout the entire process. Communication was clear from start to finish, and the overall service was outstanding. I would definitely recommend them to anyone looking for quality insulation work!
The work carried out by Mani and Mark was excellent. Very clean and very knowledgable about soundproofing.
They haven't just whacked up a stud wall and shoved it with insulation.... this is a proper company doing a proper soundproofing job.
We had multiple layers that I asked for and it has done the trick. Granted our neighbour wasn't very loud, but we are future proofing for is she moves out.
We could hear the neighbour doing general day tasks which is absolutely fine... but if she moved out and a family moved in with a young child or a kid they stayed up late watching TV... we would lose... read more
