Dimensional stability: design task for foam glass gravel
In a loose-fill layer, dimensional stability depends on grading, compaction, levels and separation of gravel from soil.
In foam glass gravel, dimensional stability requires particle grading; also check compaction.
Dimensional stability: application boundary in foam glass gravel
In foam glass gravel, dimensional stability has an important boundary. Product stability does not cancel movement in the substrate, supports or structural joints.
For dimensional stability in foam glass gravel, address this specific risk: uneven thickness.
Dimensional stability: evidence for foam glass gravel
For foam glass gravel, the dimensional stability source states: D130 dimensional stability is stated as no more than 0.2%, with a coefficient of thermal expansion of 8×10⁻⁶ 1/°C.
For dimensional stability in foam glass gravel, apply this principle. Stability is achieved only with correct bearing, properly detailed joints and no unintended bending action.
Dimensional stability: detailing for foam glass gravel
The foam glass gravel drawing develops dimensional stability through two decisions: grading; then design layer density.
For dimensional stability in foam glass gravel, dimensions and interface materials belong in the design, not in an improvised site decision.
Dimensional stability: inputs for foam glass gravel
Before assessing dimensional stability in foam glass gravel, obtain thermal movement, settlement, the movement-joint map and substrate tolerances.
For foam glass gravel, the verifiable dimensional stability requirement is to coordinate substrate movement joints, thermal movement and the insulation layout.
Dimensional stability: installation in foam glass gravel
The installation rule for dimensional stability in foam glass gravel is to build a trial area.
During foam glass gravel work concerning dimensional stability, never bridge a designed movement break unless a dedicated detail permits it.
Dimensional stability: accepting work in foam glass gravel
Acceptance of dimensional stability in foam glass gravel starts by matching delivery labels, drawings and the installed layout.
For dimensional stability in foam glass gravel, close the identified risk with a photograph, measurement or record, not a verbal explanation.
The final foam glass gravel criterion for dimensional stability is that the foam-glass layout accommodates structural movement without restraint.
Dimensional stability: conclusion for foam glass gravel
In foam glass gravel, foam glass delivers its dimensional stability benefit through a coordinated detail, not one schedule entry.
The foam glass gravel workflow for dimensional stability is to evidence the property, issue the detail, accept installation and retain concealed-work records.
