Our practical guide to installing OS-29/44/77 Sliding Doors
Alexandra works in the marketing department, and in 2014, bought her first house, which turned out to be somewhat of a ‘project’. Since then, the whole house has needed renovating, which has helped her gain a knowledge of basic DIY, decorating and making the best of a small space.
Manufactured in the UK, Origin Sliding Doors are available in an extensive range of colour options and feature some of the slimmest sightlines in the market. Here, we provide a detailed guide to installing our OS-29/44/77 Sliding Doors.

Assembling the outer frame
To begin with all sections of the outer frame will need to be carefully unwrapped and laid out in a safe area for the frame to be assembled. Stickers are applied to each section of the frame to indicate the position that they are required.
Once safely laid out, chevrons (supplied in the components box) need to be slotted into the inner and outer edge of the profile on half of each corner. There should therefore be two chevrons per corner.
The ends of the bottom track should then be completely sealed using weatherproof silicone as shown in the video. This amount of silicone filling each hole is crucial to prevent any draining water from exiting via the ends of the track once installed.
The corners of the frame can then be connected using the chevrons in the corners for alignment. We recommend that this process is followed one corner at a time, or you will find they keep pulling away from one another as you align the other end.
Using a 4mm alan key, the cleats found in the corners of the profile can be tightened to create a night tight corner joint. It is key to make sure that the two cleats are aligned and that the screw meets the receiving end of the cleat. Excess silicone coming out of the joint is then a very good sign that the joint has been correctly sealed. The excess can then be cleaned from the faces of the profile.
Lastly, the cleats in both bottom corners of the frame should be fully sealed, again to prevent any water from bypassing the prepared cleat holes.
This process can then be followed for the remaining 3 corners.

Installing the outer frame
Once assembled, the opening then needs to be prepared for the frame to be fixed in place. This is the process of packing the bottom of the opening and checking it has been levelled right across the width.
The outer frame can then be lifted into the opening and sat on top of the packers. These packers are vital to sit the frame away from the opening to ensure it can be correctly sealed and prevent thermal breaching.
The rest of the outer frame will then need to be packed into the opening to hold it in place, and then be packed accordingly to ensure it is sitting level and square.
The frame can then be drilled through, and into the opening, to create appropriate fixing holes to secure the frame in place. All prepared fixing holes in the bottom threshold then need to be fully sealed with weatherproof sealant. This is to prevent any water draining into the track from tracking their way down through the fixing screws and leaking into the opening.
Fixing screws can then be inserted into the frame to secure the outer frame in position. Throughout, and after this process, the frame should be regularly checked for level to avoid any bowing or twisting. We advise that the top track fixings are only inserted after the sashes have been installed. This allows for some movement in the head of the frame when lifting the sashes in place.
Installing fixed sash
If you are installing a fixed sash for the slider configuration, there will be fixed sash packing blocks supplied in the components box. Firstly, at least 3 of these need to be placed onto the outer channel of the bottom track. They will then need fixing in place using self-tapping screws into the frame.
The same process can then be followed for the jamb, and the top track, for the position of the fixed sash in the frame.
The fixed sash can then be lifted into place and sat on to the fixed sash packers. The sash will need to be lifted into the top track, to allow the bottom of the sash to swing into place. If this is slightly tight, you may need to lift the top track slightly to create the room for the sash to sit in place and pushed right into the packers on the jamb.
Using the screws provided in the components box, fix the sash into the outer frame. The same number of fixings should be used as per the number of sash packers to correctly secure the sash.
Installing the sliding sashes
The sliding sashes need to be lifted into the frame by pushing the top of the sash into the top track, and then swinging the bottom in. If this is slightly tight, the top track may need to be lifted slightly to get the sash into the frame.
When sitting the sash into the bottom track it is key to ensure the running gear is sat correctly on to the track runner in the frame. This can be tested by sliding the door and checking that it is operating smoothly.
If the sash needs to be adjusted in height, this can be carried out by lifting the running gear itself. The adjustment can be found on the interlocking side of the sash, using either a long PH2 screwdriver, or a ratchet extension. The running gear adjustment screw can be tightened to lift the sash, and loosened to drop it, whilst checking the sash is sitting level.
Once all sashes have been installed, the fixings can now be fitted into the top track of the outer frame and checked for level.
Glazing the sashes
The first step required is to remove the glazing beads on the sash, these can be unclipped by pushing the front edge of the bead into the sash. The side lengths should be unclipped first, followed by the tops/bottoms. It’s important to hold the top bead in place while unclipping the side lengths, as well as placing all the removed beads to one side. It is crucial that each bead goes back into the same sash, in the same positions as they are all cut specifically to size.

Two 4mm glazing packers should then be sat in the bottom corners of the sash. The glazing can then be lifted into the sash, dropped on to the 4mm glazing packers, and held in place. Glazing should always begin with an outer sash.
Further glazing packers should then be applied around the glazing to secure it inside the sash. A glazing paddle is advised to ensure that the glazing is packed appropriately and levered into position to allow packing. Packing positions should be at the bottom of the interlocking side of the sash, and the top corner then of the locking side. This ensures the glass sits level in the sash and can prevent dropping over time.
If it is an OS29 or and OS44 slider that is being glazed, the interlocking profiles will need to be bonded as per the video. The void between the glass and the interlock should have appropriate packing applied at the top, middle and bottom. These packed areas should then be fully sealed with the bonding silicone (in the components box) between the glass, and the interlock.
The glazing beads can then be re-clipped back into the sash, tops and bottoms first, followed by the side lengths. The front edge of the bead needs to be tilted towards the glass and then clipped into the U-channel of the sash profile. A glazing paddle can aid with re-installing the beads.
Wedge gasket can then be cut to size and fitted internally in the void between the bead and the glazing. Again, the top/bottom lengths should be straight cut lengths and installed into the sash first. The side lengths can then be cut at a slight angle at the ends, to meet the top/bottom gaskets at a neat joint. It is crucial to not stretch the wedge gasket as it is installed. This is to avoid the wedge gasket from shrinking over time.
