Are you thinking about updating the windows of your London home? When it comes to how to choose windows that suit your home, there are some key things to consider. From energy efficiency to functionality, this guide will break down everything you need to know.

The Different Types of Windows

If you’re confused about the different types of windows, here are some pros and cons of the most popular types:

Sash Windows

A sash window is made of two framed panes which overlap. The different parts of the window overlap to open and close. 

Made from: uPVC, wood or aluminium

Pros

  • Double or triple glazed are extremely energy efficient
  • Well-insulated so don’t allow a draft in
  • Side-hung offer good ventilation

Cons

  • Fairly easy to snap in high winds when fully opened
  • Side-hung can pose a risk if installed in a child’s room
  • Opening them can be obstructed by screens or trees outside the window

Casement Windows

These are widely used in new-build properties. They have a hinged pane which opens outwards using a lever handle. 

Casement windows can either be side-hung or top-hung. Top-hung have small windows that open at the top, whereas side-hung have large windows which open up half of the entire window. 

Made from: uPVC, aluminium or timber

Pros

  • Energy efficient
  • Aesthetically pleasing
  • Easy to clean and open

Cons

  • Older versions used for restorations are not as energy efficient as new models
  • Can only be opened halfway, limiting ventilation

Bay Windows

These are the large, rounded windows you often find on the front of Victorian homes. Just like a glass extension, bay windows increase living space and offer a lovely focal point, increasing the value of your property. 

Made from: uPVC, wood or aluminium

Pros

  • Add more floor space
  • Allows a lot of light into the room
  • Add value by making the front of the house aesthetically pleasing

Cons

  • One of the most expensive options
  • Harder to install or replace
  • Take up outside space if installing for the first time

Tilt & Turn Windows

As the name suggests, these windows tilt and turn to open. The hinged mechanism allows the top of the window to tilt open, giving just a few inches of open space. Or when the handle is turned, the window opens fully, giving fantastic ventilation. 

Made from: uPVC or aluminium

Pros

  • Good security
  • Safe for children as the “turn” feature can be locked
  • Great ventilation

Cons

  • Limit the use of blinds since they open inwards
  • Can allow rain to enter if tilted open during a storm
  • Expensive to install or replace

How to Choose Windows

Choosing new windows

Here are the top three factors to key in mind when choosing windows:

Functionality

Above all else, you need to consider the functionality of new windows. Do your current windows function well? If not, what are the issues you need to overcome?

For example, if you struggle with ventilation, your best option is windows that have wide openings to allow better airflow. 

Your Home’s Style

If you live in a 19th-century cottage, anthracite aluminium windows are going to look out of place. On the other hand, if you live in a modern new build, vintage casement windows might not be a good fit. 

Energy-Efficiency

When it comes to the type of glass for windows, ensure they carry an approved energy efficiency rating. This is usually a star system. If you’re unsure, your builder or supplier should be able to help.

Window Installation: What you need to know

If you’ve never had windows professionally refurbished before and you’re wondering what the process is, here is what you can expect:

Step 1: Measure the Window

Your contractor will come to your property and measure the openings of your existing windows. This will ensure they order the correct size for an air-tight fit. 

Step 2: Remove the Old Window

On the day of installation, all parts of the window will be removed, including the glass, window frame, and all traces of sealant around the opening.

Step 3: Weatherproof the Opening

This step is known as flashing and research shows 60% of builders don’t get this right, leading to issues with drafts and leaks down the road. 

Installing flashing correctly ensures the window is completely waterproof and any rainwater can easily run off without causing damage. 

Step 4: Installing the Window 

The frame is then lifted and gradually pushed in until the nailing fins are flush with the wall. Nails and screws are used to secure the window firmly in place. Finally, sealants are used to make the glass airtight.
