This standard is concerned with installing bay windows, including dealing with all the materials and ensuring specifications are met and installations are completed in line with Building Regulations or Building Standards and legislation. It covers preparing, positioning and securing bay window assemblies and includes structural support consideration, thermal performance and weatherproofing.
You will need to demonstrate the ability to interpret technical specifications, risk assessments and manufacturer instructions, applying safe systems of work throughout installation. The standard emphasises responsibilities including maintaining building safety, managing interfaces with load-bearing elements and ensuring fire and structural integrity are not compromised.
This standard is for you if you work in the Fenestration and Glazing Industry and are involved in on-site installation work of bay windows in domestic or commercial environments.
Performance criteria
You must be able to:
comply with organisational guidance and requirements, manufacturer instructions and health and safety legislation throughout the installation process
identify, select and handle fenestration materials and components required to meet technical specifications minimising damage and waste
identify supplied products suitability for the installation
remove, store and dispose of fenestration products from the existing structure in line with regulatory and organisational requirements causing minimal damage to the existing structure
use personal protective equipment and other tools and equipment in line with manufacturers’ instructions and organisational requirements
mark, measure, and cut sills and ancillary components to size and shape in line with specifications and safe working practices
follow all instructions to reduce material waste in line with regulations and organisational requirements
assemble bay window frames and associated components in line with specifications and manufacturer guidance
inspect and prepare apertures to ensure they are fit for purpose, structurally sound, and meet specification requirements
prepare the aperture prior to fenestration product installation in line with specification and legislative requirements
position and secure bay window frames in apertures in line with specification and organisational requirements
select and use appropriate tools, equipment, and access systems for fixing installations
identify and apply correct type, size, and quantity of fixings in line with specifications and comply with current legislation
install glass units in line with specifications and organisational requirements
install ancillary products in line with specifications and organisational requirements
apply sealing and weatherproofing materials to achieve airtight and watertight installations following manufacturer guidance and instructions
check and maintain drainage paths and holes to ensure water egress in line with standard operating procedures
verify that installed windows are plumb, level, and square after securing and that all functional elements operate in line with manufacturer’s specification and organisational requirements
conduct interim and final inspections of work against specifications, organisational quality standards, and building regulations or standards
complete finishing tasks ensuring trims, seals, and internal finishes meet specification and aesthetic requirements
maintain accurate records of installation activities, inspections, and any corrective actions taken in line with organisational procedures and requirements

accident reporting procedures and your responsibilities for compliance
why and when personal protective equipment (PPE) and other safety control measures should be used and how to use them
how to minimise damage to existing structures, cables, ancillary fitments and internal finishes during removal and installation
characteristics, quality, uses, limitations and defects associated with fenestration materials and componentswhy maintenance of tools and equipment is important and organisational procedures for reporting defects
fixing methods for bay windows and how they vary by structure type
how to confirm apertures are prepared and fit for purpose
types of weatherproofing materials used for windows and their correct application.
why it is important to maintain clear and functioning drainage paths and how to check this
hazards associated with resources and methods of work and how these can be overcome in line with legislation and organisational procedures and requirements
how risk of damage to the work and surrounding area can be minimised and why this is important
types of materials used for internal finishes and external finishes
how to select and apply sealing and weatherproofing materials to achieve airtight and watertight installations in line with specifications
why it is important for work to be carried out within agreed timescales and deadlines
how delays can impact structural integrity, customer satisfaction and compliance with project or organisational requirements
