Casement Windows

Lasting performance & efficiency

Traditional Charm
& Character

Deciding to install double glazed sash windows can come with much trepidation – especially when you are contemplating replacing your original, traditional single glazed windows with new ones. It is a popular misconception that replacing your original sash windows with double glazed replacements means that you are going to lose the charm and character of your property.


Our double glazed windows are specifically designed to match the design of your original windows, providing insulation, and enhancing the efficiency of your home, without sacrificing the unique character you admire. Which is especially important if you live within a conservation area.

We perfectly match the traditional English sash, in which the sash window is operated with a pulley system and weights. A separation bar separates the weights (steel), which move up and down on both sides of the window frame. Spring versions are also available.

Here at Trade Timber Windows & Doors we take pride in the knowledge that we focus on the minor details that others may overlook.


Double Glazed & Draught Proofing

Many original traditional timber sash windows tend to be susceptible to draughts. Despite their ability to keep out the outdoors, sash windows were originally created for a different purpose.


They were designed at a time when fireplaces were the primary source of heat in homes. To keep the fires running, sash windows had to let in some air to allow the fire to draw and burn. Sash window draughts are no longer essential in the homes of today, as most have contemporary central heating installed.

Our modern double-glazed sash windows also reduce dust and noise penetration, which are normally a common occurrence with traditional single glazed sash windows.

Did you know that to ventilate a room, the bottom and upper sashes should be slightly open? Clean, Fresh air is pulled in from the bottom, whilst the warmer, hot air is expelled from the top.


Factory Paint Finished

All our windows and doors, unless specified otherwise, come factory finislhed with four coats of protective paint. Our specialised microporous paint technology not only protects your products, but it allows the timber to breathe, meaning it is more durable and lasts longer.

Why Factory Paint?

  • Reassurance that your windows and doors are installed as a finished product, with complete protection from the elements.
  • You may rest easy knowing that your new investment will be installed properly by our trained professional fitters.
  • A factory-sprayed finish guarantees an even, solid coat.
  • Financial savings from avoiding the need for scaffolding or other access challenges.

Frequently Asked Questions

What is a casement window?

A casement window is a type of window that is hinged on one side and opens outward. They are often used in pairs, with one window opening inward and the other opening outward. Casement windows are a great option for rooms that need ventilation but don’t have a lot of space, like kitchens and bathrooms.

How do casement windows open?

Casement windows open by turning a handle that is located on the side of the window. This turns a crank that opens the window outward. Some casement windows also have a second handle that can be used to lock the window shut.

What are the benefits of casement windows?

There are several benefits to using casement windows in your home. First, they provide good ventilation since they open fully. Second, they are easy to clean since you can access both sides of the glass from inside your home. Third, they are energy efficient since they seal tightly when closed. Fourth, they offer a wider view than many other types of windows since there is no frame in the way. Finally, casement windows can be used in difficult-to-reach places like over the kitchen sink because they open outward instead of inward.

Are there any drawbacks to using casement windows?

The main drawback to using casement windows is that they require more space than other types of windows since they open outward. Additionally, they can be more expensive than other types of windows and may require special hardware or installation techniques. Finally, it’s important to make sure that the area around your casement windows is clear so that they can open fully without hitting anything nearby.

How do I choose the right size casement window for my home?

The size of your casement window will depend on the size of the opening where you plan to install it as well as your personal preferences. You should also consider how much ventilation you need in the room and whether you want your window to open fully or just partially. If you’re not sure what size window to choose, it’s a good idea to consult with a professional before making your final decision.

How much does it cost to install a casement window?

The cost of installing a casement window will vary depending on the size of the window and the complexity of the installation process. Generally speaking, however, you can expect to pay between $200 and $500 per window for professional installation services.
