Architect Support and CPD

We regularly work with Architects on a range of Building projects, whether it is supply windows and doors to a preferred Builder or for us to supply and install directly to your client, we can assist in sourcing specific products and provide a free technical measuring service.

Our showroom, the largest in the region, displays windows, doors and conservatories in Aluminium, Alu-clad, Timber and PvcU, for the discerning client we are able to provide a` One Stop Shop` with the best quality and range of products available. We have a meeting room available for you and your clients to discuss plans and consider suitable products, we will be on hand to advise, and if desired supply endless cups of tea and coffee!.

Our products range from simple PvcU Windows and Doors, through to Orangeries, Atriums, the latest powder coated Aluminium Bi-Folding Doors and everything in between.

We have a Simplicity range of PvcU Windows and Doors that offer simple clean lines and a secure but inexpensive locking system, making it an ideal choice for low cost conversions.

Our Evolution and Bygone range of Traditional PvcU Windows come in Flush Casement and Sliding sash, their quality and appearance is such that they have been considered suitable for some Conservation areas, we also have a Conservation Officer who can offer guidance for sensitive negotiations.

To support the ever increasing demand to make Buildings Carbon Neutral we also offer a complete range of Timber, Aluminium and Alu-clad windows that can achieve a centre pane U value as low as .7 or `Passivhaus` accredited standard.

Facilitating CPD units

Working with our network of partner suppliers and the Merseyside, Cheshire and Manchester Architect community we are developing a series of RIBA approved CPD seminars which are necessary for you to fulfil your obligations as a chartered member. Current key themes affecting you including the impact of the Energy Bill and Emissions Performance Standard will be addressed.

For example we are currently looking for expressions of interst for the CPD courses below:

Passivhaus Standard – planning and technical issues raised by energy efficiency goals and performance standards, U-values and implications for heat loss, ventilation and thermal control...

Window and Façade Interfaces – a look at contrasting solutions and sealing systems, including how Government Zero Carbon targets will influence design and material choices....

Timber window and door solutions – covering appropriate specifications for applications to exceed existing performance standards....


Our well equipped showroom is easily accessible from the M53 and M56 motorways and has free onsite parking so is an ideal venue.


I have undertaken numerous projects with John Knight Glass and have always found them to be professional and courteous, and the quality of the final product excellent.
