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.

Great experience start to finish - quickly came round and quoted, providing confidence in what they would do and who would be involved, co-ordinated all the individual workers who worked to a high standard. The work itself was done to a high quality and on-time, and the difference has been amazing - great company, would highly recommend.

We are all absolutely delighted with City Insulation and the work they have just completed at my brother's house in Liverpool. Sadly my brother is living with alzheimers now and he does have some noisy outbursts now and again, which is natural for this horrible illness. He is being cared for 24/7 in a normal semi-detached house in Liverpool however his neighbours are not normal and keep complaining and putting in complaints to the police / council etc. I found Adam/City Insulation on the internet and he was so understanding and came up with exactly the right solution. All the carers in... the house are delighted and its made their job easier as they no longer worry about the next door neighbours who have got to find something else to complain about now! A big thanks to Adam and his team and if you have any noise issues etc you now know who to contact! (Ps very clean, very quick job, great value for money)read more

Best experience I've had with any tradesman to be honest. We needed to improve soundproofing in commercial meeting rooms/studios and he laid out the different options very clearly so we could make the best decision from a range of budgets. His team were extremely professional, delivered the work exactly when they said they would with zero delays. Very friendly and flexible with everything onsite. Would thoroughly recommend.
