1.1 Care Of The Product
When using cleaning and lubricating products always follow the manufacturer’s instructions; take care not to use an excessive quantity. For cleaning products, test a small area of the product in an obscure location first.
Note: Do not use solvent-based or abrasive cleaning products or products containing bleaching agents.
2.0 Surveying Points
2.1 Existing Load-bearing Door Sets
Check to ensure that there is a lintel or other suitable load-transferring structure above the door set. Plastic door sets are not designed to carry dead loads.
2.2 Outward Opening Door Sets
Check the correct mode of opening (inward or outward). On outward opening a door sets a restrictor overhead restrictor, may be required as the door leaf may be subject to sudden movement by wind gusting.
2.3 Cill& Threshold
The requirement for a cill of the appropriate size and the threshold type to be used shall be checked, with attention paid to the internal floor level and the need for the door to swing clear of internal floor coverings.
3.1 Flat Doors
3.1.1 Width measurement
The width of the aperture shall be measured at three points – the top, middle and bottom of the opening. The smallest of these is used to determine the aperture width.
3.1.2 Height measurement
The height of the aperture shall be measured at three points – the left, middle and right of opening. The smallest of these is used to determine the aperture height.
3.1.3 Diagonal measurement
The squareness of the aperture shall be checked by measuring the diagnals of the aperture. If the diagonals are more than 10mm different, then the client shall be informed, and a solution agreed.
3.1.4 Front to Back measurement
Check that the installation of the new frame will not cause problems with the DPC or cavity closing.
3.2 Walls & Apertures
The aperture shall be checked to ensure that it is plumb and level.
3.3 Reveal Sizes
The difference between the internal and external reveal sizes shall be checked to ensure that the opening of the door or any door fitting will not be impeded by plaster, render or tiles etc.
4.0 Installation – Replacement
4.1 Pre-installation Checks
Prior to commencing any installation work, the sizes, type, and condition of all the door sets should be checked against both survey sizes as well as the actual aperture sizes. The door set specification, including hardware, glazing and door style, should be checked against the order acknowledgement provided by Glide and Slide Limited. Before discarding any packaging for ancillary components which may be supplied loose, particularly lever handles. Check that all ancillary components required are accounted for.
Note: Composite door sets must be stored in a dry location prior to installation. Prolonged exposure to moisture may invalidate any applicable product guarantee.
4.2 Positioning of Door Sets
The positioning of the new frame in the aperture in fundamental to the success of the installation. In general the replacement door set shall –
• Bridge the cavity
• Cover the DPC
• Be set back as far as possible in the aperture to minimise exposure to the elements
4.3 Fixing Distances
Generally, all four sides of the frame shall be secured using the following guidelines to determine the fixing spacing:
• Corner fixings should be a minimum of 150mm and a maximum of 250mm in from the external corner
• No mullion or transom fixings should be closer than 150mm, or further than 250mm from the centre line of a mullion or transom
• Intermediate fixings should be at centres no greater than 600mm
• There must be a minimum of 2 fixings on each jamb
Note: If it is impossible to find a suitable fixing position, then the nearest possible fixing should be used.
4.4 Use of installation packers
Appropriately sized installation packers shall be used adjacent to fixing positions to prevent outer frame distortion during installation. Installation packers should be incompressible, resistant to rot or corrosion, and span the full width of the outer frame profile. For fire door sets they should be of a hard, stable material. The fixings should be tightened so that the frame is held securely against the packers. Take care not to over-tighten the screws and distort the frame. Apply a small amount of silicone mastic to the shanks and heads of fixings that pass through the outer frame to ensure that no water penetrates into the frame.
Note: Packers shall be used adjacent to hinge / locking points.
5.0 Perimeter Sealing
When sealing perimeter joints take care to ensure any drainage channels are not blocked or obstructed.
