Types Of Casement Windows

Timber Casement Windows London

When you want a traditional-looking window, a casement window is often the most obvious option – especially when created from timber, which is consistent with the style of period properties.

However, we can manufacture timber casement windows in either traditional or modern designs to suit London homes where our professional team will install them for our clients.

UPVC Casement Windows

In casement windows, uPVC is renowned for its security and resilience. While uPVC casement windows can be styled as modern or traditional, they also require little upfront cost.

The cost-effectiveness of uPVC casement windows continues once we have fitted them to London homes, as these windows are easy to maintain and come with a 10-year guarantee.

Aluminium Casement Windows

These windows derive much of their reliable strength from the aluminium itself, which also lends the windows a sleek, eye-catching design easy to tailor for both period properties and new builds.

As we put aluminium casement windows firmly into place on your property in London or nearby Essex, you can take comfort from the great value this metal provides when included in windows.

Casement Windows FAQ’s

Put succinctly, while casement windows are hinged and so opened and closed much like a door, sash windows comprise multiple panels – the “sashes” – of which at least one can be slid, usually vertically, to open or close the window.

The question of whether you ought to choose a casement window or sash window for your home is a complicated one. This is why we ask all of our clients to book a free consultation with us, as this would enable us to learn more about what the client needs in a new window.

Once we have paid a free visit to your home to assess whether a casement window or sash window would be more suitable for it, we might advocate the former if, for example:   

  • You would like to improve your home’s energy efficiency
  • Your home is newly built or of contemporary design
  • You are eager to prioritise strengthening your residential security

Whatever recommendation we provide, it will be impartial – especially as our team is capable of installing both casement windows and sash windows to a professional standard.

You might have heard so “on the grapevine” – and, indeed, casement windows are widely deemed extremely energy-efficient on account of their tight seal. When the windows are shut, this seal will prevent heat from escaping the property and water from seeping into it.

However, while casement windows have traditionally been built with a firmer seal than sash windows, the modern technology built into sash windows makes them similarly energy-efficient. Therefore, eco-conscious homeowners shouldn’t necessarily shy away from utilising sash windows.

It would be easy to assume so, as uPVC casement windows do have many things in their favour when used on new-build properties. You should consider that these windows:

  • Can easily be designed to suit modern properties
  • Are often highly energy-efficient
  • Can be equipped with various modern security features

However, you shouldn’t strictly rule out considering a timber casement window or, for that matter, a timber sash window for your contemporary home – as the discrepancy in functionality between different window types is, in many instances, not as marked as it once was.

A “lipped” casement window is so-called as it slightly protrudes beyond the frame. This is due to the additional layer of sealing the window contains.

Lipped casement windows should be compared and contrasted with “flush fit” casement windows, which are level with the frame. Unfortunately, early versions of these windows tended to leak water – hence why lipped casement windows were invented to make room for additional sealing.

These days, though, flush fit casements also include two layers of sealing, just in a more compact space. Please get in touch with us for more advice about how lipped and flush fit windows differ. 

It is likely to be a wise choice – and you can rest assured that we are able to design, manufacture and install both lipped and flush fit casement windows.

As flush fit casement windows have been commonly used on properties since the nineteenth century, they can suit many homes dating from that time period or sooner. 

However, you should remain open to other options, too. For example, we can repair damaged sash windows on your heritage home it if has these.
