Double Glazing

Double glazing is a term that describes the installation of two panes of glass together with an air cavity in between. The glass is sealed together by a glazing bead and sealed with a silicone sealant.

This helps to prevent heat transfer through the window frame and reduces energy loss by up to 80%.

In this article, let’s know more about double glazing windows and how uPVC is effective?

Understanding The Science Behind Double Glazed Windows

Understanding how double-glazing works and how it can benefit your home is important.

Double glazing is a common term for two panes of glass separated by an air space. The purpose of double glazing is to improve insulation, reduce noise pollution and heat loss through windows and doors. Double glazing reduces noise by up to 50%, meaning you’ll sleep better at night without having to worry about the neighbour’s dog barking all hours of the day!

There are many different types of materials used in today’s windows such as wood frames with PVC or aluminium frames; however we recommend that you opt for UPVC windows if you want something durable yet affordable which will last longer than other materials like timber frames etc.

Double Glazing Benefits

Double glazing is the most energy efficient method of insulating a home. It reduces heat loss and provides improved sound insulation, as well as being a great way to reduce condensation, which can cause mould to grow on the windows.

Double glazing is often used in conjunction with uPVC frames and sashes because they are easy to install, so you can have all these benefits without having to do any DIY!

Energy Efficiency

It’s no secret that uPVC windows are more energy efficient than wooden ones, but what about aluminium and composite options?

U-value is a measure of how well a material can resist heat loss. The lower the U-value, the better your window will be at keeping out cold air and keeping in heat. Wooden frames have an average U-value of 1.2 W/m2K (Watts per square metre per degree Kelvin), whereas uPVC has 0.9 W/m2K – giving you an extra 20% benefit when it comes to keeping your home warm!

Aluminium windows tend to have slightly higher U-values than uPVC ones (0.5 vs 0 – although this varies depending on brand), but they’re not as durable or low maintenance as double glazing windows made from polyvinyl chloride (PVC).

Noise Reduction

Double glazing is a great way to reduce noise from both outside and inside your home. The benefits of double glazing can be seen by comparing it with single glazing. The soundproofing effect of double-glazed windows is around 50% better than for a single pane of glass, so you can rest assured that there will be less noise coming through into your home.

Double Glazing Windows

Double glazing also reduces unwanted sounds from within the house, such as footsteps or other noises made by family members or pets. This means you get peace and quiet all year round!

Security Features

A double-glazed window is more resistant to forced entry than a single pane window. The extra layer of glass makes it more difficult for burglars to break into your home, and if they do manage it, the strength of the uPVC frame will make it harder for them to smash through. This means that you’re less likely to have damage caused by attempted break-ins or vandalism – which can be costly when you consider how much insurance companies charge for repairs!

If you’re worried about theft from within your home (for example if someone breaks into your house with their own key), then you needn’t worry: double glazing helps protect against this too! In fact, research shows that homes equipped with uPVC windows were around 25% less likely than those without them under similar circumstances during a burglary attempt last year alone.”

Air Leakage Control and Moisture Control

Air leakage control is the process of preventing air from escaping a building through cracks in windows or doors. Moisture control keeps moisture out of your home by reducing condensation and mould growth on window frames.

When you have air leakage or moisture control, it means that there are fewer gaps between panes of glass in your double-glazing system. This helps to prevent heat loss through these gaps, which saves you money on heating bills!

Why uPVC A Superior Choice?

UPVC is a strong material, with a compression strength of up to 115N/mm2 (1.15Mpa). This means that it can withstand significant amounts of pressure from outside forces and still maintain its shape and integrity.

UPVC requires very little maintenance as it’s impervious so won’t rot or rust like wood-based materials would over time–this means no more painting every season!

The low-cost nature of uPVC means that replacing your existing windows with new ones could actually save you money in the long run too; especially if they were made out of timber which would have needed regular upkeep throughout its lifespan!

Energy Saving And Aesthetics

How do you know if your double-glazed windows are performing as they should? The answer is simple: with a little help from the experts at uPVC Windows, we can provide you with a free energy efficiency report. This will allow us to ascertain whether your home’s windows are in good working order and how much energy they’re saving.

Your new uPVC windows will not only make your house more beautiful but also help keep it cool in summer and warm during winter months–saving money on heating bills.

Low maintenance

Unlike timber windows, which need to be painted and repainted every few years and can become worn over time, uPVC windows are low maintenance. They’re easy to clean with a damp cloth or sponge and won’t warp in hot or cold weather conditions. Furthermore, they won’t rot like wood does–and they last for decades without needing any repairs or renovations!
