What is meant by Transom?

A horizontal timber section that divides the frame into smaller areas

Note: Transoms often have their own separate frame or are contained within the frame of a composite unit.

What is meant by Fully Finished?

Fully finished refers to the window being supplied painted and glazed. Until recently common practice has seen timber windows and doors being supplied without glass or paint and it has been the responsibility of the owner / builder / project manager to arrange for the windows to be painted and glazed. This practice can cause many problems as the work is usually done with substandard materials in substandard conditions. All of our windows are supplied as fully finished.

What is meant by Sash?

Sash refers to the elements of a window that fit within a frame which are designed to accommodate the glazing. Every window type will have a sash. Confusingly, some people refer to sliding sash windows or horizontal sash windows as ‘sash windows’.

What is meant by Mullion?

A vertical timber section that divides the frame into smaller areas.

What is meant by Jamb?

Jamb refers to the left and right pieces forming the sides of the frame of a window or door.

What is meant by Head?

Head refers to the horizontal piece forming the top of the frame of a window or door.

What is meant by Cill?

The horizontal piece forming the bottom of the frame on a window or door. (Also referred to as sill)

What is meant by Astragal Bars?

An astragal bar is our term for a glazing bar that is planted on to a piece of glass to create the impression of smaller pieces of glass. This is opposed to a glazing bar which does actually require smaller individual glazing units. An astragal bar gives a very good aesthetic replication of original narrow glazing bars, but it gives much better thermal performance.


How much will a window cost?

Due to the wide range of products and options, at this stage it is not possible to give a meaningful cost. For us to provide you with a cost, all we require are drawings (or a photograph) or details of the products you require and their dimensions. This plus any additional information regarding options will allow our first quote to be as accurate as possible.

Are your products manufactured in the UK?

Our complete range of window and door products are designed and manufactured in Donington, Lincolnshire, on the same site at which our business started in 1884.

Lead Times

What are your current lead times?

Our standard lead times are 12 weeks from confirmation of drawings and specifications.

How long does it take to get my windows changed?

A typical project will take about 12 weeks from order. This allows time for you to agree your specification, for us to provide you with your drawings and for you to approve them and finally allows time for us to manufacture your windows/doors and our Approved Partner, if relevant, to fit them. This does however vary significantly based on the size and complexity of the project.


Do you carry out site surveys?


We do conduct site surveys ourselves and have an expert team who will provide full project management throughout the process.


If your enquiry is for your own home and you require installation, then we will pass your enquiry to one of our Approved Partners in your region, who will visit you to discuss and understand your requirements, so that we are able to provide you with a quotation. Once an order has been placed, they will then usually make another visit to conduct a detailed survey to allow us to manufacture the windows and doors to your exact requirements.

Can you visit me at home?

Depending on your requirements, either one of our team or one of our Approved Partners will be in touch to arrange the next steps. On receiving your enquiry, we will contact you to explore your ideas and arrange a visit.

Do you offer installation in our area?


If requested for your project, installation will be carried out by our own certified commercial installation team


Either through our own installers or our network of Approved Partners, we have a network of installers that cover most of the UK. Please contact us with your enquiry and we will look into the specific requirements and either deal with internally or forward it to the installer that covers your area.


What wood do you use?

We select only those timber species that provide a stable base for our advanced coating system, delivering a long-lasting, low-maintenance finished product. As standard we use the following timber:

Frames and window sashes are manufactured from Engineered Redwood, free of knots and imperfections.
External mouldings and sash window linings are created in Accoya®, which has earned the highest durability rating of any timber, surviving for 25 years when submerged, uncoated, in fresh water.
For our doors, we use Grandis Hardwood. We also use Grandis Hardwood when a stain finish is required for your window or door because it’s clear faced attractive grain pattern exudes the natural beauty of timber.
We can also supply our windows and doors made completely from either Grandis, Oak or Accoya®.

Why should I consider hardwood?

If you are considering a translucent (i.e. stain) finish, hardwood will offer a more natural depth of colour. When a stain finish is required we use Grandis Hardwood because it’s clear faced attractive grain pattern exudes the natural beauty of timber.


What paint colours are available?

We have a range of beautiful paint colours in both opaque and translucent finishes. We are also able to offer a huge range of specialist colours, which can be mixed to a RAL colour, BS number or colour matched to a sample.
