Materials and wall build-ups
Learn the purpose of common layers and components, including structural backing, insulation, membranes, cavities, and external finishes. Focus on continuity, junctions, and why small gaps can matter.
- Key terms: vapour control, airtightness, drainage, thermal bridging
- Practical prompts: what to look for before closing up a wall
- Common mistakes: missing continuity at corners and penetrations
Façade and cladding foundations
A calm introduction to how façade systems are assembled: subframes, brackets, rails, panels, tolerances, and fixings. Learn why sequencing and setting-out influence quality and safety.
- Key terms: bracket spacing, expansion, alignments, support zones
- Practical prompts: checking substrate condition and references
- Common mistakes: misaligned rails and skipped checks at junctions
Insulation and weather protection
Understand how insulation, membranes, and sealing concepts support comfort and durability. Focus on simple logic: water control, air control, and continuity at junctions.
- Key terms: wind-tight layers, laps, penetrations, drainage paths
- Practical prompts: checks before cladding and internal linings
- Common mistakes: damaged membranes and inconsistent lapping
Fixings and fastening essentials
Learn the basics of choosing the right fastening approach for a substrate, understanding load direction in plain terms, and keeping to safe drilling and installation routines under supervision.
- Key terms: embedment, edge distance, torque, substrate condition
- Practical prompts: pre-drill checks and a simple installation sequence
- Common mistakes: wrong bit choice, poor hole cleaning, rushed setting
