High Energy Bills? Optimising Your Energy Efficiency

High Energy Bills? Optimising Your Energy Efficiency

How can I combat high energy prices?

In your homes lurks a silent culprit. They are responsible for your high energy bills, the dogged way you guard the thermostat and the fact that it takes ages to reach a good ambient temperature. It’s not your kids, your dog or your spouse: it’s your inefficient windows!

The energy crisis has created bills that are still almost 60% higher than they were in 2021. The surge in energy prices has hit homeowners hard, with average annual energy bills for two to three-bedroom homes skyrocketing. 

Without a significant cost reduction on the horizon, it’s important to tackle the issues that you can resolve. As approximately 30% of your energy escapes through your windows, solving this should be your number one goal for a warm and happy home. 

What makes windows energy efficient?

To gauge the energy efficiency of windows, it’s crucial to understand two pivotal factors: the U-value and the Solar Heat Gain Coefficient (SHGC). The U-value measures the rate at which heat escapes through a window. In this context, lower U-values signify superior insulation and heightened energy efficiency. On the other hand, the SHGC gauges the extent to which solar heat infiltrates through a window. In warm climates, a lower SHGC is desirable to minimise unwanted heat gain.

A single glazed window usually has a higher U-value around 5.8 W/m2K and double glazing can bring this up quite a bit to around 2.7W/m2K. For the best, you’ll need to look at secondary glazing which can achieve a U-value of 1.2W/m2K and lower. This matches (and usually beats) your average triple glazed unit while costing significantly less. 

By including low-emissivity (low-E) coatings, you can reduce the solar heat gain and retain more of your central heating. Alternatively using regular glass allows the solar heat into the room, which may be preferential depending on your location and the locations of your windows at the property. 

Do I need to replace my windows?

A standout feature of Clearview Secondary Glazing is its seamless integration with existing windows. Homeowners need not sacrifice the character and charm of their properties to achieve thermal efficiency goals. This can be especially beneficial to historic or listed properties where there are fewer options for home improvement. 

Secondary glazing is fitted alongside your existing windows, creating a cavity that provides an insulating layer. This creates an insulating air gap between the original window and the new glazing. The outcome is a barrier that substantially diminishes heat transfer, augments thermal performance, and offers extra benefits such as noise reduction and improved security. This also means that you won’t need to be keeping a keen eye on the thermostat anymore!

Additionally, Clearview Secondary Glazing extends a diverse range of customization options, encompassing various frame materials and over 200 RAL colours. This empowers homeowners to preserve their homes’ unique styles while upgrading their windows.

Is it eco-friendly?

Our secondary glazing achieves carbon neutrality within just one year of installation. By retaining your existing primary windows, you can minimise your carbon emissions while still enjoying improved comfort and security. Additionally, you won’t need scaffolding outside your property during installation, reducing disruption to your life.

While solutions such as triple glazing can be an excellent addition to your property in specific cases, to gain the full benefit can be costly. The true benefits are only realised when you replace all your windows, resulting in a significant amount of time, waste and most importantly cost! There’s no point in reducing your energy bills if it means that you’re paying an arm and a leg to do so. 


In an era defined by spiralling energy costs and heightened environmental consciousness, the pursuit of energy efficiency emerges as a common goal that benefits both homeowners and the planet. Energy-efficient windows, including the offerings from Clearview Secondary Glazing, play a pivotal role in shrinking energy consumption, trimming utility bills, and cultivating a more comfortable and sustainable living milieu. 

With Clearview Secondary Glazing, homeowners can uphold their homes’ character while supercharging their energy efficiency. It’s a harmonious solution that not only enhances quality of life but also champions environmental stewardship.
