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. This means stable temperatures throughout rooms all year round, staying warm in the winter and cool in the summer.

Here are just a few ways we can City insulation can help

Reducing the transfer of 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 secondary glazing unit 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.

Keep the warm in and the cold out

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 your home. That means lower temperature settings in winter, lower energy consumption, and lower bills. A more stable indoor temperature gives you and your family optimal comfort 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 also helps to reflect a significant portion of the sun’s heat, preventing it from entering the house. This reduces the need for air conditioning or electric fans, resulting in energy savings and a reduced environmental impact.

City Insultation’s secondary glazing expertise brings a range of thermal benefits for homeowners of all size properties – from flats to mansions. Our secondary glazing adds a critical layer of insulation, reduces heat loss and heat gain, and improves comfort with steady temperature control. Over the course of a single year it can also help drive significant savings on energy bills.

I can't praise City Insulation enough they are very professional, informative, courteous and they certainly know their stuff. They completed our lounge and dining room soundproofing in two days, which was completed with great care and respect to our home and furnishings (thanks to a great installation team). Do yourself a favour and choose City Insulation, it's no surprise that they get regular 5 star ratings.

Adam & Rachel were professional, knowledgeable and genuine people to deal with. I knew nothing about sound proofing but they talked me through all my options to help me understand the best options for my particular wall. They were also really helpful on suggesting work that fitted within my budget, there were other more expensive options but they recommended the best package for me that would have the most impact not just the most expensive. The sound proofing they installed on my party wall to reduce noise from neighbours (screaming children, overly loud tv, shouting etc..) has been game... changing. Since being completed me and my partner can now sit and have a conversation without having to put music or tv on in background to drown out the neighbour noise. The work was very professional, the finishes excellent and all the lads took real care to protect existing furniture, carpets etc... The work was completed in a very professional manner and attention to detail was fantastic. Some firms do their bit and leave but they even arranged for other tradesmen to help complete the redecoration work after they had left i.e. plasterer, plumber (to re-mount a radiator) whose work was also of an equally excellent standard. I would highly recommend city insulation to anyone wanting to work with a truly professional business whose end product does exactly what it says on the tin! Thank you Adam & Rachel you were a pleasure to deal with.read more

I recently used City Insulation to help with soundproofing my semi-detached house. I could hear my neighbours TV, door slamming and arguments, to the extent that I felt like I lived with them! City Insulation installed their ‘Independent Wall plus both upgrades’ system on every adjoining wall to my neighbours and the results have been great! The noise has been reduced by around 80% in the three rooms and I no longer feel the intrusion from next door. I knew nothing about soundproofing before the job was done, and City are not local to where I live so it was a bit of a’ leap of faith’.... However, Rachel has been fantastic in responding to all my queries, Adam was really knowledgable about getting the right solution for me and the installation team (Nick, Jack and Brad) were so efficient in getting the work done and to a really high standard. Thank you team for all your help - it’s really appreciated!read more
