Joints and interfaces: design task for walls and façades
In an external envelope, joints and interfaces becomes visible where the substrate, insulation and finish meet.
In walls and façades, joints and interfaces requires continuity of the insulation layer; also check interfaces around openings and compatibility with finish layers.
Joints and interfaces: evidence for walls and façades
For walls and façades, the joints and interfaces source states: The installation guidance calls for longitudinal and transverse joints to be staggered and sealed with the specified system.
For joints and interfaces in walls and façades, apply this principle. Joint quality is as important to insulation continuity as the properties of the product itself.
Joints and interfaces: inputs for walls and façades
Before assessing joints and interfaces in walls and façades, obtain joint width, stagger pattern, filling material and details for complex interfaces.
For walls and façades, the verifiable joints and interfaces requirement is to issue dedicated details for corners, penetrations, supports and transitions between product types.
Joints and interfaces: detailing for walls and façades
The walls and façades drawing develops joints and interfaces through two decisions: the panel layout; then fixing method and sequence of finish installation.
For joints and interfaces in walls and façades, dimensions and interface materials belong in the design, not in an improvised site decision.
Joints and interfaces: application boundary in walls and façades
In walls and façades, joints and interfaces has an important boundary. Closed cellular glass is not a continuous barrier when installation joints remain open.
For joints and interfaces in walls and façades, address this specific risk: local breaks in the layer.
Joints and interfaces: installation in walls and façades
The installation rule for joints and interfaces in walls and façades is to verify substrate flatness.
During walls and façades work concerning joints and interfaces, inspect ends, corners and cut pieces before applying the protective layer.
Joints and interfaces: accepting work in walls and façades
Acceptance of joints and interfaces in walls and façades starts by matching delivery labels, drawings and the installed layout.
For joints and interfaces in walls and façades, close the identified risk with a photograph, measurement or record, not a verbal explanation.
The final walls and façades criterion for joints and interfaces is that every transition has a drawn filling method and an acceptance criterion.
Joints and interfaces: conclusion for walls and façades
In walls and façades, foam glass delivers its joints and interfaces benefit through a coordinated detail, not one schedule entry.
The walls and façades workflow for joints and interfaces is to evidence the property, issue the detail, accept installation and retain concealed-work records.
