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 the difference between a door and a frame?

A door is the actual moving part that opens and closes, while the frame is the structure around the door that supports it. The frame is also what the door hinges are attached to.

What are the different types of doors?

There are many different types of doors, but the most common are entry doors, interior doors, and garage doors. Entry doors are typically made of wood, fiberglass, or steel, and they can be either solid or hollow. Interior doors are usually made of wood or a composite material, and they can be either flush (flat) or paneled. Garage doors are usually made of metal, and they can be either sectional or rolling.

What are the different types of door frames?

Just as there are many different types of doors, there are also many different types of door frames. The most common type of door frame is the wood frame, which is typically made from pine or fir. Other popular materials for door frames include steel, aluminum, and PVC.

How do I measure for a new door?

When measuring for a new door, you will need to take three measurements: width, height, and thickness. To measure the width, simply measure the distance between the side jambs (the vertical members that support the door). To measure the height, measure from the top of the door to the bottom. Finally, to measure thickness, use a ruler or tape measure to determine how thick the door is at its thickest point.

How do I know what size door I need?

The size of your door will depend on two things: the size of your opening and the amount of clearance you need. To find out what size door you need for your opening, simply measure the width and height of your opening (in inches). Then, add 2 inches to each measurement; this is your rough opening size. As for clearance, you will need at least 1/2 inch on each side of your door for it to swing properly. However, if you have limited space in your home or office, you may want to consider a pocket door instead. Pocket doors slide into a cavity in the wall when they’re opened, so they don’t require any additional clearance space.

What is a jamb?

A jamb is a horizontal member that forms part of a doorway’s frame; it runs along both sides and across the top of an opening (the head jamb). The term can also refer to vertical members that support a window sash (the window’s frame). In both cases, jambs help to support and stabilize doors and windows.

What is weatherstripping?

Weatherstripping is a sealant that helps to close off gaps around doors and windows in order to prevent drafts from coming into your home or office. It is typically made from rubber or foam and can be applied in strips along both sides of a door or window (or around its perimeter).

How much does a new door cost?

The cost of a new door will vary depending on the size, style, and material. A basic entry door can start as low as $100, while a more elaborate storm door can cost upwards of $1,000. Interior doors generally fall somewhere in between these two extremes.

Should I install a new door myself?

Installing a new door is generally not a difficult task, but it’s important to make sure that it’s done correctly. Incorrectly installed doors can cause problems like drafts or leaks. If you’re not confident in your ability to install the door properly, it’s best to hire a professional contractor to do it for you.

What are some common problems with doors?

Common problems with doors include draftiness, sticking/jamming, gaps at the bottom/top/sides of the door, and warping due to moisture damage. These problems can usually be fixed fairly easily by making adjustments to the hinges or weatherstripping (for draftiness), sanding down sticking points (for sticking/jamming), or adding trim (for gaps). Warping is usually more difficult to fix and may require replacing the entire door if it’s severe enough.
