Construction Jargon Explained
Planning a new build or renovation can be exciting, but the technical language of construction can feel overwhelming. To help you navigate conversations with builders and contractors, we’ve created this glossary of common building terms. Whether you’re confused about “board and skim” or unsure what “snagging” means, we’ve got you covered.
1. Board and Skim
Definition: Fixing plasterboard (drywall) to walls or ceilings (“board”) and applying a thin coat of plaster over it to create a smooth, paint-ready finish (“skim”).
Why it matters: It’s a fast, cost-effective way to achieve flawless walls.
2. Stud Wall
Definition: A lightweight, non-load-bearing wall made of timber or metal framing, typically covered with plasterboard.
Why it matters: Perfect for creating new rooms or dividing spaces in renovations.
3. Load-Bearing Wall
Definition: A wall that supports the weight of the structure above it, including floors, roof, and sometimes other walls. It transfers this weight down to the foundation.
Why it matters: These walls are critical to a building’s stability. Removing or altering a load-bearing wall requires additional structural support, such as steel beams, and may need input from a structural engineer.
4. First Fix
Definition: The initial phase of construction where structural and hidden works, like plumbing pipes and electrical wiring, are completed.
Why it matters: Lays the foundation for all visible finishes.
5. Second Fix
Definition: The finishing phase of construction, including fitting sockets, light switches, and decorative items like skirting boards.
Why it matters: This stage brings your project to life.
6. Snagging
Definition: Identifying and fixing minor defects or unfinished work after the main construction is complete.
Why it matters: Ensures your project is delivered to the highest standard.
7. U-Value
Definition: A measure of a material’s ability to insulate. Lower U-values indicate better insulation.
Why it matters: Helps you meet energy efficiency standards and reduce heating costs.
8. DPC (Damp Proof Course)
Definition: A protective layer installed in walls to prevent rising damp.
Why it matters: Essential for protecting your property from moisture damage.
9. RSJ (Rolled Steel Joist)
Definition: A steel beam used to provide structural support, especially during renovations involving the removal of walls.
Why it matters: Ensures your structure remains safe and stable.
10. Rendering
Definition: Applying a cement or acrylic coating to external walls to improve appearance and weather resistance.
Why it matters: Can enhance curb appeal and protects your home.
11. Cladding
Definition: A material applied to the exterior of a building to provide insulation, protection from the elements, and an enhanced appearance.
Why it matters: Cladding can improve the look of your property and contribute to its energy efficiency and weather resistance. Common materials include timber, metal, brick slips, and composite panels.
12. Screed
Definition: A layer of mortar or concrete applied to floors to create a smooth, level surface.
Why it matters: Prepares floors for tiles, carpet, or other finishes.
13. Self-Levelling
Definition: A cement-based compound that spreads and levels itself when poured, creating a smooth and even surface with minimal manual effort.
Why it matters: Ideal for smoothing out small imperfections in floors or preparing them for finishes like tiles or laminate. It’s applied in thin layers (1-10 mm) and dries quickly, making it a popular choice for quick fixes or finishing touches.
14. Soffit
Definition: The underside of a roof overhang or eaves.
Why it matters: Improves ventilation and adds a polished look to your roofline.
15. Splice
Definition: The process of joining two pieces of timber, metal, or other materials together to extend their length or repair a damaged section.
Why it matters: Used to maintain the structural integrity of beams, joists, or other critical components during construction or repair work.
16. Principal Elevation
Definition: The main, front-facing external façade of a building, usually the side with the main entrance that faces the road.
Why it matters: It often determines the architectural style and is an important consideration in planning applications and regulations, especially in conservation areas.
17. Foundations
Definition: The structural base of a building that transfers its weight to the ground, ensuring stability and support.
Why it matters: Foundations are critical to the safety and durability of a structure, preventing settling, cracking, or collapse over time. Types of foundations include shallow (e.g., strip foundations) and deep (e.g., piles) depending on the soil and building requirements.
