Sierra Sliding Doorset


Sliding patio doorsets offer a combination of functionality, aesthetics, and practicality, making them a popular choice for both residential and commercial applications where indoor-outdoor connectivity and space optimization are desired.


Indoor-Outdoor Connectivity: Sliding patio doorsets offer a seamless transition between indoor and outdoor living spaces, allowing occupants to enjoy natural light, fresh air, and views of the surrounding environment.

Space Saving: Unlike traditional hinged doors that swing inward or outward, sliding patio doorsets operate by sliding horizontally along a track. This mechanism saves indoor space, making them ideal for areas with limited floor space.

Enhanced Aesthetic Appeal: Sliding patio doorsets often feature large glass panels that create an expansive and open feel, enhancing the visual appeal of both interior and exterior spaces. They come in various panel layouts, finishes, and styles to complement different architectural styles and interior décors.

Improved Natural Light: The large glass panels of sliding patio doorsets allow ample natural light to penetrate indoor spaces, reducing the need for artificial lighting during the day. This can help create a brighter and more inviting atmosphere inside the building.

Ventilation: Sliding patio doorsets can be partially opened to allow ventilation while maintaining security and privacy and allowing occupants to control airflow according to their preferences.

Accessibility: Sliding patio doorsets provide easy access for individuals with mobility challenges, such as wheelchair users or elderly people. The smooth sliding mechanism requires minimal effort to operate, making them user-friendly for people of all ages and abilities.

Energy Efficiency: High-quality sliding patio doorsets are designed with energy-efficient features such as insulated glass, thermal breaks, and weatherstripping to minimize heat loss or gain, improving indoor comfort and reducing energy costs.

Security: Modern sliding patio doorsets are equipped with advanced locking mechanisms, multi-point locking systems, and tempered or laminated glass to enhance security and protect against intrusions.

Most of our systems can be supplied with both double and triple glazing. However, in the majority of instances double glazing is the preferred option. For more information and to determine which is best for your project, please contact us to arrange an appointment with a consultant who can explain the main differences to you.

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. 

Ask your Janex consultant for further details and they’ll be only too happy to help.

We offer composite timber front and back doors. There are many different styles, colours and specifications when it comes to choosing between these three products. We recommend speaking to one of our Janex consultants or visiting our showroom in order to understand the differences in more detail.

Yes, in most instances you will be able to choose a different colour on the inside of your product to the outside, so for example you could have white inside and red outside.  Or, yellow one side and black the next! A Janex consultant will be able to help you confirm your choice is available.

Replacing your old windows with new double or triple glazed windows will typically add value to your property. Not only do new windows look aesthetically pleasing to the eye they also increase the thermal efficiency in your home keeping you nice and toasty in winter and keep the heat out in the warmer months making double or triple glazed windows an essential decision factor to many potential purchasers.

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.
