Glass Partitions London | 14 August 2019
The first Glass Partition panel is cut to size and slid through both fixed parts of the floor shoes and into the first upright post. the panel is jacked up with a floorlifter and the floor pan is slid into position, before lowering the board onto the assembled shoes. the next upright post is put into position and fixed to the head and base with fixing brackets. the process is then repeated. If the partition is being used for a wireway, holes will need to be punched or drilled at the foot of the upright post for cables, which can run under the floor pans.
GLASS PARTITION WALL ABUTMENT
When a wall abutment is reached and an upright post cannot be used, a split (breakdown or abutment) post is used to fix the panel with a flat bar fixed to cover up the panel edge.
GLASS PARTITION LAMINATE SKIRTING
Self-adhesive foam strip is applied to both edges of the back of the plastic, then lightly held in position and marked as to where the foam crosses the upright post. The skirting foam is cut to allow for the posts and then fixed in position. It is important that this type of skirting is installed in conditions that will reflect its temperature in use, as contraction / expansion can otherwise occur.
GLASS PARTITION ALUMINIUM SKIRTING
In a similar way, upright post positions are marked on the skirting lip, then the gap is milled out and using skirting foam at the base fixed flush to the partition. in some situations, if the lip is a suitable depth, it can be turned upside down and with a foam strip stuck to the unlipped edge, the skirting foam cut away for the upright post and then screw fixed to the partition.
GLASS PARTITION DOOR FRAME
Door frames are generally supplied to site in a pack with pre-drilled and mitred stiles and head transom and are machined for lock keep and hinges. Door seals, hinges and sufficient fixings are included. The frame is fitted between two plumbed upright posts, set out dimensions are often included in the door pack but the transom width also determines the necessary opening. Frame stiles are generally supplied oversize so they need to be cut to length to fit the door height. care should be taken to allow for carpet thickness if required. If the system calls for a solid or glazed panel above the door, this should be inserted prior to the fixing of the door head transom. It is essential to use either switch posts or strong posts adjacent to full height doors and good practice on standard height doors to use switch posts with the added benefit of facility for a light switch.
Once the frame is fixed in position with mitres tight, the frame seal and lock keep are fitted. Hinges are fixed in the frame stile in accordance with manufacturers’ instructions. if lift-off hinges are to be used, ensure that the shorter pin is on the bottom hinge. Door / smoke seals are inserted.
Door frame in position, the door is usually fitted at the end of the installation to avoid damage.
In the same way as for solid modules, the head channel is fitted, this time with the deep side uppermost, together with the acoustic foam and the first upright post.
GLASS PARTITION FULL HEIGHT GLAZING
The next upright post is cut to size and positioned to suit the module width (pre-bracketed transoms can be used to accurately set out the upright posts) and fixed to the head and base with fixing brackets, ensuring that the post is plumb in both vertical planes. the installation continues in this manner, installing junction posts as required. A 100mm high flaxboard or timber packer is located in the floor shoe outers (inners are not used) and the floor transom is fitted directly on top of the packer. if it is necessary to raise the transom for levelling purposes then additional packing should be provided underneath the packer.
GLASS PARTITION PART MODULE GLAZING
The floor shoes are fixed and the panel cut to size and placed in position. The next upright post is cut to size and positioned at the edge of the panel, set out by the transom, and then fixed into position. The installation continues in this manor, installing junction posts as required. Pre-bracketed transoms are then fixed across the tops of the panels and fixed to the upright posts ensuring that transoms in consecutive modules are level and in line. this method completes the fixing of half glazed elevations, for mid glazed the upper transom is installed at door head height with panel above. It is now possible to fit the glazing chair (single centre, single offset or double glazed).
The horizontal chairs are cut to fit the module, then the vertical sections. glazing beads are then square cut, unless beads are chamfered, in which case a mitre cut should be made and fitted in place prior to glass of up to 7mm in thickness being fitted.
