ENGINEERING
MATTERS.
Large glass areas are a system of loads, water, thermal movement, tolerances and logistics. We resolve these questions before fabrication.
PROCESS
From drawing to installation junction.
System selection
We compare systems around geometry, sightlines, opening types, performance and architectural compatibility.
Structural analysis
We consider wind loads, deflection, mullion and transom spacing, glass weight and support conditions.
Glass specification
Safety, solar control, thermal performance, acoustics, dimensions and weight are defined for each group of units.
Thermal performance
We coordinate target performance and the weak points of the installation junction.
Drainage
Water management from thresholds, façades and external channels is resolved before units reach site.
Installation details
We develop interfaces with floors, façades, roofs, waterproofing and structural substrates.
BIM / CAD
Technical material supports coordination with architects and adjacent contractors.
EARLY INVOLVEMENT
Earlier involvement means fewer compromises.
System depths, thresholds, axes, glass make-up, drainage and lifting access are best defined before the final façade specification.
This preserves architectural intent, gives fabrication clear inputs and avoids solving basic details on site.
KNOWLEDGE / ENGINEERING
BIFORIUM technical library.
Concise professional notes on glass, acoustics, thermal performance and installation. No marketing shortcuts — only the parameters that actually affect the assembly.
SOLAR-CONTROL GLASS
How we specify solar-control and low-e glass: g-value, light transmission, Ug, façade orientation, heat treatment and the appearance of large glazed areas.
↗02SAFETY GLASS
ESG, VSG and laminated safety glazing: how we select glass by breakage behaviour, impact risk, fall protection and architectural application.
↗03LARGE-FORMAT GLAZING
Engineering for oversized glass: IGU weight, jumbo formats, deflection, support, vacuum lifting, crane access and installation logistics.
↗04GLAZING ACOUSTICS
How we engineer window and façade acoustics: Rw, C, Ctr, asymmetric panes, acoustic laminate, frame airtightness and the installation joint.
↗05WINDOW THERMAL PERFORMANCE
Ug, Uf, Uw, warm-edge spacers and installation thermal bridges explained. How we assess thermal performance of aluminium and PVC glazing.
↗06INSTALLATION JUNCTIONS
Airtightness, thermal insulation, waterproofing, drainage and thermal support profiles. How we engineer installation joints for aluminium and PVC systems.
↗TECHNICAL DETAILS / 04
Installation and building junction library.
Not universal installer diagrams, but explanations of critical interfaces: what carries load, where insulation runs, how water is managed and which inputs are needed for a project-specific detail.
WINDOW IN INSULATION
How we coordinate windows installed in the insulation plane: bearing, fixing, airtightness, thermal layer and external weather protection.
↗02LOW HS THRESHOLD
Coordination logic for low HS and panoramic sliding thresholds: bearing, floor level, drainage, waterproofing and external channel.
↗03WARM BASE
Why a thermally improved structural base is used below windows, doors and sliders: load transfer, thermal break, waterproofing and floor build-up.
↗04FACADE TO WALL
Coordination of curtain-wall interfaces with opaque walls: anchors, movement, insulation, internal airtightness and external weather protection.
↗05DRAINAGE & WATER
How we coordinate window, sliding and curtain-wall drainage with terraces, channels and waterproofing membranes.
↗06GLASS RAILING BASE
Conceptual design of a frameless glass railing base: structural substrate, anchors, slab edge, waterproofing and base-profile drainage.
↗FOR ARCHITECTS
Drawings ready, but the system is not fixed yet?
We can review geometry, glass and critical junctions before they are locked into the final window schedule.
How collaboration works ↗GLASS ENGINEERING
The IGU as its own engineering discipline.
Build-ups, coatings, safety, warm edge, argon and an input checklist.
