A Guide to Choosing the Right Double-Glazed Window

Installing cutting-edge double glazing can significantly increase the energy efficiency of your home while simultaneously reducing noise pollution and condensation build-up. With a growing emphasis on energy efficiency, comfort, and aesthetics, selecting the ideal double-glazed window has become a crucial aspect of home improvement projects across the globe.

Join us as we explore the key factors, considerations, and benefits that will empower you to choose the perfect double-glazed window that aligns with your needs and enhances the beauty and functionality of your living space.


There are various materials used for window frames, including uPVC, timber and aluminium. Each has their own advantages and disadvantages; uPVC remains popular due to being energy efficient, durable and easily maintained requiring only periodic wiping downs to remain energy efficient and durable.

When purchasing double glazed windows, it is essential to consider what kind of spacer will be used between panes of glass. A metal or polymer spacer containing desiccant material should be selected if possible to prevent condensation between panes; otherwise a minimum width of 12mm wide spacer should provide optimal performance (larger sizes may reduce noise transmission).

Double glazed windows typically use air or one of three forms of gas to provide greater insulation between panes, such as Argon (the most popular and cost-effective choice) or Krypton (more costly but superior insulation properties).

Considerations when purchasing double glazed windows include glass thickness. A thicker pane may help prevent heat loss while thinner panes may be better at minimizing noise transmission.

Consider your style when purchasing double glazed windows. Casement windows work on hinges to open outward, providing increased ventilation in homes that need it. Sash windows offer more traditional style with their sliding mechanism – these should always be kept as period properties to keep their character intact.

Whatever style or material choice you decide upon, always opt for locally manufactured double glazed windows to ensure their highest quality and they fit seamlessly with surrounding architecture.

At present, double glazing comes in an extensive variety of colors to fit every home and design aesthetic. Although it might be tempting to opt for what’s trendy right now, remember that window frames will remain part of your property for several decades so make a choice that won’t bring regret later on.

White uPVC windows are an ideal addition to any property style, from modern to classic and everything in between. Their smooth exterior lends them an aesthetic appeal, and can either feature glossy or matt frames; matte frames will blend into the exterior design without drawing attention away from any details, while glossy frames add a modern flair that adds visual interest and modern style.

Wood-stain effect windows offer the aesthetic of timber windows while still offering all of the advantages of uPVC, making them an excellent choice for traditional properties with features like Georgian bars and stained glass. In more modern homes, dark wood stains such as rosewood or Irish oak may work particularly well.

Walk around your neighborhood and observe what kind of window colors your neighbors have installed to get an idea of what works and doesn’t; try matching or complementing these so your house appears more connected to its surroundings.

Many manufacturers also provide dual color options so you can have different colours on either the inside and exterior sides if you aren’t sure which would work best.


Double glazed windows offer more security than single pane ones as their double sheets of glass make them harder to break through and can reduce UV rays that cause sun damage to carpet, furniture and paintings inside your home.

Double glazed windows create an insulation between their panes that traps air, helping your home remain cooler in summer and warmer in winter without increasing energy bills. Double glazed windows also help reduce noise pollution – ideal for homes near busy roads or any other noisy environments.

There are four primary types of double glazing: tilt and turn, casement, vertical sliding and Georgian bar. They each offer different operations and features that make them suitable for different situations; the choice ultimately comes down to personal taste or desired aesthetic.

Tilt and turn double glazed windows are easily operated via hinges along one verticle edge, enabling them to tilt outwards for opening. They’re perfect for hard-to-reach areas or when seeking maximum acoustic control and energy efficiency benefits.

Casement double glazed windows are operated using hinges on either side of their frames, making them suitable for almost any space and opening inwards or outwards for convenient operation. Casements allow light to fill a room while providing beautiful views of nature – however they don’t offer as much acoustic control as tilt and turn windows, therefore being unsuitable for properties with sloped or period features.

Energy efficiency

Double glazing can help lower energy consumption while making your home more comfortable, while simultaneously helping reduce noise levels in noisy areas.

When selecting double glazing for your home, however, it’s essential that you consider all factors that affect its energy efficiency; such as frame materials, glazing features and gas fills/spacers which all affect energy use and consumption.

Energy efficiency of double-glazed windows can be measured using visible light transmittance (VLT). A lower VLT indicates better heat retention. To balance out too much sun coming through your windows can cause it to overheat while too little can make your home feel dark and gloomy.

Another key factor affecting energy efficiency is the thermal resistance of frames. Wood, uPVC and composite frames all act as excellent insulators and can enhance double glazed window performance; while metal frames allow heat conductivity that could compromise your windows’ energy efficiency.

Double-glazed windows often include inert gases such as argon to increase performance, though other gases like krypton or xenon may also help improve insulating properties further. Your choice will ultimately depend on both your needs and budget – some options can be more expensive.


Home improvements that focus on increasing security should be among the top priorities for homeowners. Double glazing can make an effective contribution to this goal by offering two panes of glass that are harder to break. It is vital that a trustworthy company provide your customization and installation so you can have confidence in the safety of your home.

Double glazed windows are often considered safer alternatives to single pane windows as they feature an air, argon or xenon gas-filled gap between them that can help improve insulation while simultaneously helping reduce noise pollution into your property. Furthermore, this gap helps minimize heat transfer while improving energy efficiency and enhancing soundproofing properties.

Before, double glazed windows had an exterior bead to help hold glass in place; this posed a security risk since it could easily be removed by stripping and stripping out. Modern double glazed windows such as those from First Home Improvements now incorporate this beading internally, making it much harder for thieves to gain entry to your property through these windows.

Modern double glazed windows come equipped with multipoint locks which feature shoot bolts that locate into locking points in the frame when you turn the handle, meaning even if the frame weakens over time, these bolts will still lock into place and prevent burglars from being able to gain entry and remove the window.

No matter whether it is made from uPVC or aluminum frames, there is sure to be something suitable that meets both your property needs and security concerns.
