KEY PARAMETERS
What matters at specification stage.
Assess MasterLine 8 on the actual sash format.
Installation depth
77 mm
Visible width
from 97 mm
Frame Uf
up to 1.0 W/m²K
Element Uw
up to 0.88 W/m²K
Infill / glazing
up to 72 mm
Max. height
up to 2800 mm
Max. vent weight
up to 300 kg
Air permeability
class 4
Watertightness
E900
Wind resistance
C5
Sound insulation
up to 46 dB
Visible frame width, glass weight, hinge type and the real Uw of the element matter more than a theoretical catalogue maximum. The fact that a system can reach a certain limit does not mean every opening should use that configuration.

SYSTEM CONTEXT
* Reynaers figures relate to defined MasterLine 8 test assemblies. In a project, we tie them back to the selected size, glass and hardware.
With MasterLine 8, glass, sash geometry and frame position drive the final result.
Our engineering approach ↗HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
START A PROJECT
We select the system around the architecture.
Show the largest opening sashes and a few typical windows. We will check where MasterLine 8 works without unnecessary over-specification and where another configuration is preferable.
