The Crystal Full Glass Triple Glazed Door is designed for homeowners and contractors seeking a high-performance, energy-efficient entryway that does not compromise on natural light. With a superior U-value of 1.1 W/m2K, this door is ideal for reducing heat loss in modern residential builds, though its heavy triple-glazed construction requires professional installation due to the weight of the unit.

A U-value measures the rate of heat transfer; a lower value indicates better insulation. 1.1 is an excellent rating for a glass door, signifying high thermal efficiency.
Always view the door from the outside. If the hinges are on the left, it is a left-hand door; if they are on the right, it is a right-hand door.
The door is manufactured as a sealed 36mm triple-glazed unit. While the glass can be replaced, it should be done by a qualified professional to maintain the argon gas seal.
Yes, the included hardware is designed for exterior use and finished to withstand typical weather exposure.
You will need standard carpentry tools including a spirit level, cordless drill, shims, and a high-quality sealant for the frame perimeter.
Check that the frame is square and level; adjust the hinges if the door has dropped slightly or is binding against the frame.
Inspect the rubber gaskets for debris or damage; ensure the locking points are fully engaging by adjusting the keep plates.
Clear any accumulated dust or spiderwebs from the vent slots and ensure the internal flap mechanism is not obstructed.
Installation requires careful attention to the door handing; always determine if the door is left-hand or right-hand opening by viewing the unit from the outside. Ensure the frame is perfectly level and plumb before securing it to the aperture using the provided glazing packers. The PVC cill should be installed first to provide a stable base. For routine care, clean the glass with a mild soap solution and a soft cloth to avoid scratching the low-E coating. Lubricate the hook locks and hinges once annually with a silicone-based spray to ensure the mechanisms operate smoothly over time. Avoid using abrasive cleaning agents or steel wool on the PVC frame.
