Remove existing windows, doors and panels and prepare apertures
Overview
This standard involves preparing apertures during the refurbishment of a property. This standard would not be appropriate for a new building or new installation. This can be carried out in relation to replacement of windows (including rooflight, oriel and box sash), doors and panels either as part of a window or door system or which form part of a conservatory or curtain walling. You will need to remove any existing windows and doors from apertures and restructure apertures or create new openings as required. You will need to check apertures against specifications, and remove all debris. Finally, you will need to provide new surface finishes ready for installation
This standard is for you if you work in the Fenestration Industry and are involved in on site removal of existing windows and doors and preparation of apertures for installation work
Performance criteria
You must be able to:
- check and confirm suitability of materials and other resources
- identify products for removal and agree schedules of work with appropriate person(s)
- identify fixtures and fittings that will prevent or restrict installations following standard operating procedures
- remove and store fixtures and fittings to allow effective refitting following safe working practices
- remove components, materials and outer frames from apertures following safe working practices and in ways that cause minimum damage to structures and surrounding areas
- inspect, fit or replace any existing damp proof barriers required to meet specifications
- handle materials to minimise damage following safe working practices
- cut, shape and assemble materials to meet specifications
- minimise waste following safe working practices
- check materials fit plumb and square to prepared apertures following standard operating procedures
- check new or restructured apertures meet specifications
Knowledge and Understanding
You need to know and understand:
- how to identify effective work
schedules how to identify dangerous materials and infestations that might be present
types of structural supports available and when they are needed
why it is imporatnt to remove fixtures and fittings in a way that allows effective refitting where required
how to remove existing frames and components of different materials to avoid damage to surounding areas and why this is important
different types of materails used for internal and external finishes
how to prepare apertures for installation
consequences of not preparing apertures correctly
typical problems that can occur in the preparation of apertures and how to deal with these
