LGS / 3D
Explore how steel framing, insulation and linings form a wall, floor and roof. Each layer has a specific role.
These diagrams explain assembly principles. Thicknesses, connections, member spacing and performance are project-specific. They are not construction drawings.
LGS / 01
A wall with continuous insulation outside the framing. Service voids, boards and vapour-control position are coordinated through design.
Select a layer to read its role
Boards form the room finish and contribute to fire and acoustic protection. Type, layers and fixings follow the selected system.
A continuous layer with sealed joints and penetrations limits air leakage. Vapour resistance and its position follow moisture analysis.
Open C-studs sit in U-tracks. Cavity insulation contributes to heat and sound control; bracing is omitted from this layer diagram.
A specified board closes the frame. Joint treatment, weather exposure and any structural contribution depend on the selected system.
Insulation covers the studs to reduce thermal bridging. Thickness, fixings and fire characteristics are designed together.
A support system separates cladding from insulation. Drainage, ventilation openings, insect protection and required cavity barriers need detailed coordination.
LGS / 02
An example of a dry floor. Load transfer, vibration and acoustics are checked together.
Select a layer to read its role
Lower boards close the structure. Hangers and board layers follow fire and acoustic requirements.
Engineered open sections carry the floor. Cavity insulation helps absorb sound; lateral restraint and supports need separate detailing.
The deck transfers loads to joists. Its joints and fixings must match its designed role.
Limits direct impact-sound transfer. Perimeter isolation prevents rigid sound bridges.
Distribute loads above the resilient layer. Selection depends on use and imposed loads.
Timber, tiles or other finishes must suit the substrate. Wet areas need additional waterproofing and sealed penetrations.
LGS / 03
A flat roof has a designed fall to drainage. This exploded diagram omits falls and outlets.
Select a layer to read its role
Closes the space below the roof. Services and fire protection are coordinated with the structure.
Sections or trusses transfer roof loads to walls. Infill and insulation positions require thermal and moisture assessment.
Supports the roof package. The selected system must suit loads and fixing requirements.
A sealed layer connects to the corresponding wall layer. Penetrations require planned details.
A continuous layer above the structure reduces thermal bridges. Falls may be formed in the structure or suitable tapered insulation.
Membrane, edges, parapets, outlets and emergency overflows work together. Drainage needs to remain accessible for maintenance.
LGS / 04
One clear sloping plane. A dual-pitch roof has two coordinated planes and a designed ridge connection.
Select a layer to read its role
Boards close the room and provide the protective layers required by the design.
Engineered sections carry the roof. Supports, lateral restraint and bracing depend on the span and loads.
A continuous layer at the designed location connects to walls and penetrations.
Reduces interruptions at structural members. Cavity and external insulation are assessed as one assembly.
The specified underlay directs incidental water towards the eaves. Laps and penetrations follow system instructions.
Ventilated space, battens or profiles and the covering are selected together. Roof slope must suit the chosen covering.
The substrate (1), moisture separation and bottom U-track (2), and anchorage/hold-down (3) connect the panel to its foundation. Levelling, anchor edge distances and base protection need individual design. Anchor type and number require calculation.
The upper wall (1), floor members and edge assembly (2), and lower wall (3) need a clear load path. Bearing, restraint, web reinforcement and acoustic separation depend on the chosen system.
The wall head (1), roof members (2) and connectors (3) transfer compression and wind uplift. Screw arrangements, member restraint and thermal-envelope continuity must be coordinated.
