Secured by Design (SBD) is the official police security initiative that works to improve the security of buildings and their immediate surroundings to provide safe places to live.

SBD’s product-based accreditation scheme – the Police Preferred Specification – provides a recognised standard for all security products that can deter and reduce crime.  This includes domestic windows and doors, and the components within them such as locks, hinges etc.

Janex is a registered member of Secured by Design and many of our products have been tested to meet the demands of the standard.

A U-Value, in simple terms, indicates how well your window will be at retaining the internal heat within your property and preventing it from escaping to the outside.  U-Values are measured in Watts per square metre, or W/m2 K. The lower the U-Value number, the better the heat retention of the window. All new or replacement windows require a minimum U Value of 1.6 W/m2 K.

It is very rare that you’ll need permission to replace your existing windows and doors. However, you will need to check to see if you are located in a conservation area as you may be restricted with what designs or materials you are allowed to use this may also be the case if your property is a listed building.

Absolutely! All of our windows and doors are made to measure and can be tailored to your requirements. This includes choosing from a range of colours, finishes and styles.

‘Engineered’ timber is the key to the strength and long-lasting properties of our windows and doors. It is created through a very old technique of layering wood sections with the grain of one section in the opposing direction to the grain of its neighbour.
