What to specify
State the full assembly, air-gap arrangement, facing requirement and target test method. Thermal resistance, emissivity and reflectance must not be transferred from one construction or assembly to another.
State continuous and short-term service conditions. A temperature range or material recommendation is provided only when it is supported for the exact quoted construction.
Constructions
Foil laminate and reflective composite roll constructions are quoted against the requested layers, faces, core, width and roll format. Fire, vapour, breathability and thermal claims require construction-specific evidence and are not implied by the family name.
MOQ, lead time and samples
We supply roll goods and confirm the applicable slit width and roll format in the written quotation. MOQ, price basis, sample availability and lead time are confirmed for the exact construction before order.
State the application, layer structure, width, roll length, core and destination. Any sample, technical value or supporting document is supplied only when it is identified for the quoted construction.
Scope and documentation
Leetaiheng supplies these materials as roll goods. The exact layer structure, face, slit width, roll format and applicable tolerances are confirmed in writing for each quotation.
Compliance and test documents are construction-specific. Name the target market and required standard; we will confirm whether a current document with the required scope is available before order.
Frequently asked
Which face should point towards the air gap?
Installation depends on the tested assembly and the project designer’s requirements. Confirm the exact construction and follow the applicable system documentation.
Do you supply pieces or roll goods?
We supply roll goods. Slit width, roll length and core are confirmed in the quotation; piece-format supply is outside our scope.
