Glazing is selected from actual Uw, solar, acoustic and safety requirements; large vents are also checked for glass weight.
Reynaers Aluminium / Aluminium windows & doors
MasterLine 8
A versatile high-performance Reynaers platform for thermally insulated aluminium windows and doors with extensive design and opening options.

KEY PARAMETERS
What matters at specification stage.
Assess MasterLine 8 on the actual sash format.
77 mm
from 97 mm
up to 1.0 W/m²K
up to 0.88 W/m²K
up to 72 mm
up to 2800 mm
up to 300 kg
class 4
E900
C5
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.
PROFILE CROSS-SECTION
MasterLine 8 profile geometry in detail.
This image shows the system's profile geometry, chambers, thermal breaks and glazing zones. The final junction is selected for the opening scheme, glass build-up, dimensions and project loads.

ARCHITECTURAL CAPABILITY
Why we consider this system.
Functional, Hidden Vent, Renaissance and Deco designs
Watertightness up to E900 in tested configurations
Wind resistance up to C5
RC2 / RC3 and fire-rated variants
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 ↗BIFORIUM / PRACTICE
A system only works as a whole with glass, hardware and installation.
Installation position, support, insulation, sealing and drainage belong in the specification rather than being improvised on site.
Open engineering details ↗Hardware limits the viable vent geometry just as much as the profile. Concealed hinges and automation need early coordination.

FAQ / SPECIFICATION
Questions to close before specification.
Can the system be selected only from catalogue performance?
No. Published values help shortlist options, but the finished element still has to be checked for size, glazing, weight, hardware, loads and installation detail.
Does every opening need the same glazing build-up?
Not necessarily. A south-facing elevation, a bedroom near traffic, a large fixed pane and an entrance leaf can require different glazing within the same project.
When should the installation detail be coordinated?
Before the final order. Finished-floor level, insulation, waterproofing, structural support and drainage can change the frame, threshold or final manufacturing size.
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.
