Joinery (Second Fixing)

MODULE 6

Joinery (Second Fixing)

Joinery, also referred to as second fixing, is a specialized carpentry discipline that involves the crafting and installation of wooden fixtures and fittings in a building after the structural work (first fixing) is complete. Unlike rough carpentry, which focuses on framing and structural elements, joinery emphasizes precision, aesthetics, and functionality. Skilled joiners work with high-quality timber and engineered wood products to create bespoke or pre-manufactured components that enhance a building's interior and exterior.

Key Aspects of Joinery (Second Fixing)

1. Manufacturing Doors, Windows, and Staircases

• Doors: Joiners craft and fit internal and external doors, including panel doors, glazed doors, and fire-rated doors. They ensure proper alignment, smooth operation, and weatherproofing where necessary.

• Windows: Joinery involves making wooden window frames, sashes, and casements, often incorporating double glazing for insulation.

• Staircases: Joiners design and install straight, spiral, or curved staircases, including treads, risers, balustrades, and handrails, ensuring structural integrity and compliance with building regulations.

2. Skirting Boards, Architraves, and Moldings

• Skirting Boards: These are installed at the base of walls to cover the joint between the wall and floor, providing a neat finish and protection from damage.

• Architraves: Decorative moldings around doors and windows that conceal gaps and enhance aesthetic appeal.

• Coving & Moldings: Ornamental trim elements (e.g., cornices, dado rails) that add character to ceilings and walls.

3. Built-in Furniture (Cabinets, Shelving, Wardrobes)

• Joiners design and install custom-made storage solutions such as fitted wardrobes, kitchen cabinets, bookshelves, and entertainment units.

• These are often tailored to maximize space efficiency while blending seamlessly with the interior design.

4. Fitting Locks, Hinges, and Hardware

• Joiners ensure that doors and windows function correctly by fitting hinges, handles, locks, and other ironmongery.

• Precision is crucial to guarantee smooth operation, security, and longevity of moving parts.

Materials and Techniques

• Timber Selection: Hardwoods (oak, mahogany) for durability and softwoods (pine) for cost-effectiveness.

• Joinery Methods: Mortise and tenon, dovetail, and biscuit joints for strength and seamless finishes.

• Machinery & Hand Tools: CNC routers, planers, chisels, and sanders for shaping and refining wood.

Importance of Joinery in Construction

• Enhances aesthetic appeal and adds value to properties.

• Provides functional and space-saving solutions (e.g., fitted furniture).

• Ensures precision and longevity of fixtures, reducing maintenance needs.

Joinery is a blend of craftsmanship and technical skill, playing a crucial role in the final stages of construction and interior finishing.
