70mm Frame Extension Add-on

(Choice of thickness and length)

Frames fit better and operate more smoothly!

Strong, clip-on extensions for increasing the width or height of 70mm window and door frames. Designed to snap securely onto Profile 22 outer frames, without the need for screw fixings. These PVC-u frame packer add-ons are available in a choice of thickness and length.

Frame extensions are used when the outer frame is smaller than the structural opening, or when extra clearance is required to accommodate interior plaster lines or external obstacles, such as fascia or external cladding. They prevent the frame being buried into the plaster, or from the deep plaster line preventing full opening of a door hinge. A thick frame packer can also be used to allow the fitting of a trickle vent at the head of a door or window, when additional ventilation is required. The frame extensions are available in four thicknesses (15mm, 20mm, 35mm, and 50mm), and can be combined with each other to provide alternative coverage. For example, clipping a 35mm and 20mm extension together will satisfy a space of 40mm.

There are many situations that may require the use of an add-on to increase the width of a frame on one or more sides. Common examples include:

Allow a frame to be used when the opening is larger than the frame itself.
Reduce cost by allowing standard window and door sizes to be ordered, with shortfall in width or height made up with add-ons.
Create space around the frame to clear deep plaster, render, tiles, etc, and to accommodate external obstacles.
Provide clearance on hinge side of a door to allow full operation.
Help line up one frame to another for a neat and consistent appearance.
Raise the bottom of the door to improve floor level transition

Did you know? The rigid chambered profile features a male side that clips onto the female clip channel of Profile 22 outer frames, and a female side that mimics the outer frame. This allows frame extensions to lock onto each other, and create thicker add-ons when necessary.
