THRESHOLD OPTIONS
INTEGRATED CILL & THRESHOLD
Integrated cill and threshold profile, total height of just 55mm, delivers a full weather rating while maximising the sash height of the door leaf — resulting in more glass and less frame.
Total height of 55mm (cill included)
STANDARD THRESHOLD
Standard 50mm threshold provides a full weather break, helping keep your property dry and warm in all conditions. It is recommended for external bifolding doors.
Total height of 75mm (cill included)
LOW THRESHOLD
Our 20mm low threshold offers a more seamless appearance, with reduced weather protection. But is ideal for homes with mobility requirements or small children, minimising trip hazards.
Total height 45mm (cill included)

ADDONS + EXTRAS
Frame Extension?
You have the option of adding a 20mm blank frame extension to either the TOP or SIDES of your frame.
Frame Extension Profiles: These are supplementary profiles that increase the overall height of your existing door frame.
Purpose: They are useful for accommodating a larger structural opening, deep plaster, render, or tiles, ensuring a seamless fit.
Installation: The extension is typically attached to the existing door frame, and then the entire assembly is installed into the opening. They are custom-sized to match the original door frame's colour and width.
Trickle Vents?
Trickle vents can be added to either your Door Sash, Frame or Add-on Bar.
Flat Pack?
Frames up to the size of 5m wide will be delivered assembled, but you have the option of having your order shipped to you flat packed, so you can assemble the frame onsite where access is limited!
ASTRAGAL BARS?
Horizontal or vertical bars are added to your order. External bars are fitted manually after the doors and glass are installed. Internal bars sit inside the sealed double-glazed unit, giving the appearance of divided glass while maintaining full performance.
