Thermally Efficient Aluminium Bi-Fold Doors
The door system combines aluminium with a full-width thermal core designed to reduce heat transfer through the frame while retaining the slim appearance associated with aluminium doors.
This construction provides an excellent combination of thermal performance, strength and contemporary aluminium styling for modern residential projects.
28mm Toughened Double Glazing
The standard specification includes 28mm toughened double glazing, providing large glazed areas while maintaining the safety and thermal performance required from an external folding door.
- Standard Glass: 28mm Toughened Double Glazing
- Standard U-Value: Approximately 1.4 W/m²K
44mm Triple Glazing Upgrade
For projects requiring enhanced thermal performance, the doors can be upgraded to 44mm triple glazing.
Depending on the complete door specification, the triple-glazed system can achieve a U-value of approximately 1.0 W/m²K.
Triple glazing is particularly worth considering for new-build properties, highly insulated extensions and renovation projects where improved thermal performance is a priority.
