Window Fitter Course

Lesson 1 • Health, Safety, and Regulatory Basics

Outlines mandatory safety obligations, personal protective equipment, and building regulation concepts. Compliance awareness is established before any practical activity.

Lesson 2 • Frame Materials and Their Properties

Examines uPVC, aluminum, timber, and composite frames. Students evaluate material strengths, thermal performance, and maintenance needs.

Lesson 3 • Window Types and Their Applications

Introduces casement, sash, tilt-and-turn, and fixed window types. Students match each type to appropriate building applications.

Lesson 1 • Power Tools and Their Safe Operation

Covers drills, jigsaws, angle grinders, and screw guns. Correct guard use, speed settings, and pre-use checks are emphasized.

Lesson 2 • Measuring and Leveling Equipment

Teaches accurate use of spirit levels, laser levels, and plumb bobs. Precision measurement directly affects fit quality and weatherproofing.

Lesson 3 • Hand Tools for Window Installation

Identifies chisels, mallets, pry bars, and hand saws used in fitting. Students practice correct grip, technique, and safe storage.

Lesson 1 • Producing Accurate Order Specifications

Translates field measurements into supplier order forms with correct deductions. Students practice completing specification sheets to industry standards.

Lesson 2 • Surveying Existing Window Openings

Teaches condition assessment of lintels, sills, and reveals before removal. Identifying structural issues early prevents installation delays.

Lesson 3 • Understanding Architectural Drawings

Decodes floor plans, elevations, and section views relevant to window openings. Students extract dimensions and specifications directly from drawings.

Lesson 1 • Forming New Window Openings

Introduces cutting new openings in masonry and timber-frame walls. Temporary support and structural considerations are addressed throughout.

Lesson 2 • Safe Removal of Existing Windows

Details the sequence for removing glazing, beads, and frames without structural damage. Safe disposal and recycling of old materials are included.

Lesson 3 • Assessing and Repairing the Opening

Covers repair of damaged reveals, sills, and lintels before new frame installation. Structural integrity must be confirmed before proceeding.

Lesson 1 • Installing uPVC Frames

Addresses uPVC-specific techniques including reinforcement checks and thermal expansion gaps. Students install and align multi-part uPVC assemblies.

Lesson 2 • Frame Positioning and Packing

Teaches placement of frames using packers to achieve level, plumb, and square alignment. Correct packer positioning prevents frame distortion under load.

Lesson 3 • Fixing Methods for Different Wall Types

Covers frame fixings into masonry, timber stud, and steel-frame walls. Fixing type and spacing are matched to wall construction and frame material.

Lesson 4 • Checking and Adjusting Installed Frames

Verifies installed frames against tolerance standards and corrects misalignment before glazing. Early correction avoids costly rework after glazing.

Lesson 1 • Bead Glazing and Wet Glazing Methods

Covers snap-in bead glazing for uPVC and aluminum, plus wet glazing with putty or silicone. Each method is matched to frame type and exposure.

Lesson 2 • Setting Blocks and Glazing Packers

Teaches correct placement of setting blocks and edge packers to support glass loads. Improper block placement causes seal failure and glass stress.

Lesson 3 • Safe Handling and Lifting of Glass

Covers suction cup use, glass trolleys, and team-lift procedures for large units. Correct handling prevents breakage and personal injury.

Lesson 4 • Glazing Unit Types and Specifications

Distinguishes single, double, and triple glazed units, including low-emissivity and laminated glass. Students read unit specifications and verify deliveries.

Lesson 1 • Sash Window Weights and Balances

Covers cord-and-weight systems and spiral balances for sash windows. Correct balance selection ensures smooth, counterweighted sash operation.

Lesson 2 • Window Restrictors and Child Safety Devices

Fits restrictors and safety locks to limit opening width in compliance with fall-prevention requirements. Correct placement is verified by function test.

Lesson 3 • Hinge Types and Installation

Covers butt, friction stay, and egress hinges for casement and sash windows. Correct hinge placement ensures smooth operation and structural support.

Lesson 4 • Handles, Locks, and Security Hardware

Installs espagnolette locks, cockspur handles, and multi-point locking systems. Security hardware must meet applicable performance standards.

Lesson 1 • External Finishing and Weatherproofing

Applies external trims, render stops, and flashing to complete the weatherproof envelope. External finishes must integrate with the existing facade system.

Lesson 2 • Client Handover and Documentation

Prepares handover packs including warranties, maintenance guides, and compliance certificates. Clear documentation protects both installer and client.

Lesson 3 • Final Inspection and Testing

Conducts operational tests, air-tightness checks, and visual inspections against a quality checklist. Defects are recorded and resolved before handover.

Lesson 4 • Internal and External Sealing

Applies foam backing rod, silicone, and acrylic sealants to all frame-to-wall junctions. Correct sealant selection and tooling prevent air and water infiltration.
