Integrating Sliding Doors In Glass Box Extensions

How sliding doors in glass box extensions can transform a home

Due to their ability to seamlessly connect indoor and outdoor areas, sliding doors are a common option for glass box extensions. Large expanses of glass are frequently used in glass box extensions, also referred to as glass box additions or glass box conservatories, to maximise natural light and offer unobstructed views of the surroundings. This design idea is complemented by sliding doors because they make it simple to access the outside while still maintaining a striking appearance.

The pro’s of integrating sliding doors in glass box extensions.

Size and Type of Sliding Doors: Sliding doors come in various sizes and configurations. For a glass box extension, it is common to use large, floor-to-ceiling sliding doors to maximise the sense of openness and create a seamless transition between the indoor and outdoor spaces. Options like multi-panel sliding doors or telescoping doors can offer flexibility in terms of opening width.

Frame Materials: Various frame materials, such as aluminium, uPVC, or timber, can be used to build sliding doors. Due to their strength, longevity, and sleek appearance, aluminium frames are frequently chosen. The material for the frame should complement the glass box extension’s overall design and the level of maintenance that is desired.

Energy Efficiency: Since glass box extensions have a lot of glazing, it is important to take energy efficiency into account. To reduce heat transfer and guarantee cosy indoor temperatures, look for sliding doors with high-performance glass and thermal breaks in the frame, at minimal windows our products score great energy ratings at 1-1.1 W/m2K. Glass with low-emissivity (low-E) coatings can also help limit heat gain or loss.

Security and Weather Resistance: A sliding door should have appropriate security features, such as strong locking mechanisms and toughened or laminated glass, to increase safety including PAS 24 in some instances. Additionally, consider weather-resistant elements like drainage systems and weather seals to stop water infiltration during heavy downpours. The majority of sliding door systems are fitted with a type 2 lock, this is an internal thrust lever system and has a PAS 24 certification which is the highest security rating on sliding glass doors.

Examples of sliding doors in glass box extensions.

Dalston House

A family home in East London underwent a larger renovation that included this small glass addition. The house needed a modern twist, but the architects also wanted to keep the rooms’ charm and individuality.

A straightforward set of sparse windows on the rear elevation were housed in the longest of these skinny glass extensions. This two-pane sliding glass door gave the room’s limited space the minimal glass design it needed while also providing direct garden access.

Making sure that glass was maximised and frame was minimised with such a small opening to the rear was a crucial factor in the glazing specification. The small windows and sliders provided the necessary vertical sightlines and floor to ceiling glass.

Drax Avenue

This home in South West London extended, improved natural light and provided better links to the garden thanks to a glass extension with sliding doors.

Due to their thin frames, the minimal windows were chosen as the sliding doors for the glass extension. The structural glass extension has a completely frameless appearance. To carry this design to the patio door design, slim framing was needed for the sliding doors.

Camberwell New Road

The Grade II listed house in South London was renovated and expanded using a small glass addition. To create more space and enhance connections to the garden, a small glass addition was added to the back of the terrace house.

Due to its thin framing, the small glass extension used a minimal windows sliding door system. The designers were able to maximise the glass in the extension design while minimising the frame sizes. This was a crucial requirement for a small glass building.

A two-pane minimum window with one fixed pane and one siding panel created the slim siding door. The steel goal post that was installed beneath the narrow sliding glass door as part of the glass extension design. For an all-glass design, back painted glass was used to cover the steel posts on the exterior of the small windows.
