Thanks to advanced technologies and modern manufacturing techniques there’s a huge variety of windows on the market today with a vast range of specifications. Choosing which is right for you depends on many different factors such as your type of property, the window’s application, aesthetic and architectural requirements, and your personal choice.

There are a few key questions you should ask yourself when you are considering what type of windows will best suit your property:

  • Can I have windows custom designed to match the exterior of my home?
  • What type of windows will work best for energy efficiency?
  • How secure will my new windows be?
  • How much maintenance will they require?
  • Will the windows provide adequate ventilation all year round?
  • What is the installation process?
  • What colour and style options are available?
  • Are the windows covered by a warranty?
  • What is the lifespan?
  • Do they allow for sufficient sunlight?

Factors like energy efficiency may not be first thing that come to mind when shopping for new windows. However, installing the right windows supplied by a reputable home improvements company can help to reduce your energy consumption resulting in smaller energy bills. A well manufactured modern window is not only stylish, but will also protect your home from the elements. There is a great deal more to consider when purchasing new or replacement windows than just cost and aesthetics.

Window Materials

Today’s windows come in a variety of materials including uPVC, aluminium, steel, timber and fibreglass. Each material has a lot of benefits that make them a wise choice for new or replacement window installation. You need to consider what type of material will work best for your specific needs. The following section will examine the pros and cons of the different types of materials available for your window installation.

uPVC Windows

uPVC windows, or vinyl windows as they are called in the United States, are a hugely popular choice for replacement windows as well as many new housing developments. They are known for their energy efficiency and are remarkably cost effective. Below are some of the other advantages of uPVC windows:

  • Virtually Maintenance Free: uPVC windows require little to no maintenance other than regular cleaning with soap and water.
  • Diverse: uPVC windows are available in a wide array of styles and colours and can be custom designed to fit your home.
  • Energy Efficient: uPVC windows provide excellent thermal insulation. They keep your home cooler in the summer and warmer during the cold winter months. If you install A+ Rated uPVC windows you will notice a reduction in your energy bills and enhanced levels of comfort.
  • Modestly priced: uPVC windows are typically the least expensive of the various types of window materials. However, this does not mean they are of a lower quality. They are highly durable and do not rot or rust.

There are few disadvantages with uPVC windows. They come in a huge variety of colours and styles, provide excellent thermal efficiency, and can essentially pay for themselves over their lifetime due to the energy savings that can be achieved.

Aluminium Windows

Aluminium windows are a popular choice and they tend to suit modern properties. Some of the advantages of aluminium windows are:

  • Aesthetics: Aluminium windows typically have a slimmer profile than uPVC and timber windows due to the material’s high strength-to-weight ratio. This makes them a popular choice in new developments of flats, contemporary houses and commercial settings.
  • Low maintenance: Aluminium windows are exceptionally resistant to corrosion from severe weather conditions and they will not crack, warp or swell which gives them quite an excellent lifespan. They are also easy to clean and require little to no maintenance.
  • Wide variety of style and finishes: Aluminium windows can be easily customised to fit your specifications with a great choice of finishes, styles and glazing options. They can also look very stylish in modern contemporary buildings.
  • Thermal efficiency: One concern raised by homeowners is that, as a metal, aluminium is associated with poor thermal efficiency. However, a good quality aluminium window will incorporate what is called a ‘thermal break’ to address this issue and reduce the flow of thermal energy. A ‘thermal break’ is a barrier between the frame that prevents heat from escaping and cold air from entering thus improving thermal performance.

Steel Windows

Steel windows are highly durable and require very little maintenance although they’re not commonly used in residential applications. Steel doors are popular with commercial properties as they are secure whilst also being fire resistant. They tend to be more expensive than other options due to the material and installation costs. Below are some of the advantages of steel windows:

  • Aesthetically appealing: Steel windows are typically an excellent choice for larger projects. They are available in a wide array of styles that can be designed to fit your taste and your budget.
  • Security: As steel is exceedingly robust by its very nature if offers excellent security.
  • Easy to clean: Steel windows are very durable so they do not easily decay or warp. They do require more maintenance than other material types but they are very durable and long lasting.

Timber Windows

  • Stylish appeal: Timber windows are classic. They can be custom-designed to fit your specific needs and you can paint, stain or polish them as you choose.

Fibreglass Windows

Fibreglass windows are relatively new compared to the types of windows mentioned above. Here are some of their key features:

  • Easy to maintain: Fibreglass windows require very little regular maintenance and are easy to clean. They are resistant to warping, rotting and cracking giving them a good lifespan.
  • Eco-friendly: They do not emit toxic fumes and are also able to self-extinguish in the event of fire. Fibreglass is highly resistant to environmental factors such as high temperatures or corrosive salty conditions.
  • Energy efficient: Fibreglass windows provide good thermal insulation due to their low U Value and high R Value.

Fibreglass windows are the most expensive of the window materials, costing nearly double that of uPVC windows. They also weigh a great deal more than uPVC windows and installation may take longer.
