How Does Double Glazing Reduce Heat Loss?

At T&K Home Improvements, we manufacture many double glazing products including uPVC and aluminium windows. If you’re a homeowner, you may have heard about how double glazing reduces heat loss.

You might be wondering how double glazing keeps your home warmer. In this article, we will explore how it helps to reduce heat loss and ensure a warmer home. Read on to learn more.

What Is Double Glazing?

Double glazed products are popular with homeowners because they are effective in keeping homes warmer. These windows have two panes of glass close together, with a small space in the centre known as an air gap or tight air pocket. This helps to reduce condensation and dampens sound outside. As a result, you will enjoy a quieter home.

Spacers Separate the Glass Between the Two Panes 

A window with double glazing fitted in contains a spacer that helps separate the two panes of glass. The further away the spacer is, the more insulation you will get. With this in mind, it’s recommended to choose 24mm because that way, you will get the best insulation in your home. 

A spacer bar works by keeping the seal unit warm, while also helping to reduce condensation. Our double glazing windows come with spacer bars as standard, and have some of the lowest U Values on the market.

Insulating Properties

Heat energy is transferred from hot spaces to cold spaces through convection. However, convection requires a good conductor. The air gap acts as an insulator, preventing heat from escaping through the glass. This means warm air is retained, while cold air is kept outside.

Reflective E-Coating

Another important factor in reducing heat loss is the reflective e-coating on the glass panes. This coating minimises heat loss through the windows by reflecting the heat into the room. As a result, this will keep you warm and comfortable.

The reflective E coating acts as a protective coating, reflecting the heat outside. There is less need for air conditioning, so heat reflecting glass can help cut out your bills in the summer.

Reduces Noise Pollution

Investing in double glazing helps reduce noise pollution because the glass panes don’t make direct contact with one another. As a result, you will benefit from a much quieter room.

Manufactured With uPVC or Aluminium Frames

But it’s not just the air gap that helps reduce heat loss. The materials used in double glazed windows also play a role. At T&K Home Improvements, our double glazed windows are manufactured from uPVC and aluminium, resulting in durable, long lasting frames.  

The frames are easy to maintain and are less likely to get damaged by tough weather conditions. All you have to do is wipe them with a cloth and they will look immaculate.

Benefits of Double Glazing

Investing in double glazing is a long-term solution that can improve the energy efficiency of your home and reduce your carbon footprint.

Double glazing lets in plenty of natural light, creating the illusion of a bigger space. This makes your home brighter and warmer, which could help reduce energy bills.
