DO YOU NEED PLANNING PERMISSION TO CHANGE WINDOWS & DOORS?

When replacing windows or doors in a conservation area, it is always recommended to check with your local planning officer before beginning any project. You may be asked to make your request formally in writing, which will require submitting your application with window drawings, our team can assist you with this.

As for listed properties, you will definitely require consent to make a change to any windows or doors. If your upgrade involves the replacement of single glazed windows and doors with double glazed products of the same material, the success of your planning application will depend entirely on the information submitted and the opinion of the officer involved. The Nine Zero team have a wealth of experience in working with local planners and can help overcome any problems by adapting some of the details to achieve a like-for-like replacement.

What type of glass do you use in your windows?

Nine Zero offer a choice of 12, 14, and 24mm double glazed units with 24mm being standard. The wider the space between the two glass panes the higher the thermal performance, until you reach 16mm. Any cavity larger than 16mm can have an adverse effect. In projects that have strict conservation restrictions and require a sympathetic upgrade, single glazing may be the only option. Our high-performance weather seals and the engineering of our products will help thermal performance.
