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 would highly recommend Adam and the team at City Insulation. They are polite, reliable and carried out the soundproofing job I needed in the timescales given. We had to tweak a few things along the way but this was dealt with promptly.
