Which glazing can be used with MasterLine 8?

The published system range is 4–62 mm. Glass size, weight, hardware and structural verification must also be checked.

Which security class is available for MasterLine 8?

The published system status is RC2, RC3, PAS 24. A resistance class applies only to the tested overall construction including glazing, anchoring and installation.

How is the whole-window U-factor for MasterLine 8 calculated?

It is calculated from frame and glass areas, the verified frame Uf value, glazing Ug value, glass-edge length, spacer Psi value and any mullions, transoms or special geometry.

02 · Profile construction

From profile section to verified project planning.

Profiles, glazing, seals and hardware are treated as one system. This separates published values from the items that require project-specific verification.

System platform

Planning: frame, sash, mullion and meeting stile

Glazing

Published range: 4–62 mm.

Planning: build-up, weight, size and spacer

Seals and drainage

Answers organized around real specification questions.

Frequently asked questions remain readable on the page and are also provided as structured FAQ data.

Which values are binding for MasterLine 8?

Only the values of the specifically engineered and verified unit configuration are binding, including profiles, size, opening type, glazing, hardware, anchoring and installation interface.

Which glazing can be used?

The published system range is 4–62 mm. A specific glass build-up also depends on size, weight, sash dimensions, hardware and structural verification.

Is RC2, RC3, PAS 24 automatically included?

No. A resistance class only applies to the tested assembly of profiles, hardware, glazing, anchoring and installation. The required class must be specified for the project.

How is the binding whole-window U-factor determined?

From the frame share, Uf value of the actual profile combination, glazing Ug value, glass-edge length, spacer Ψ value and, where applicable, mullions, transoms and special geometry.
