Door and Window Layout

The elevation is divided into three zones:

End zones: brick masonry walls with large glass doors

Middle zones: continuous window strips, upper and lower rows

Door positions: main entrance doors at both ends

---

System Components

The door/window system includes:

Steel window frames: steel mullions supporting glass panels

Glass panels: factory glazing, natural light into production

Entrance doors: large steel-framed glass swing/sliding doors

Brick infill: masonry wall at building ends

Window sills and heads: structural steel lintels over openings

Advantages

Natural light — 7m wide window strips bring light deep into factory

Large door access — 5.25m wide doors fit trucks and equipment

Brick infill durable — brick walls at ends resist impact

Steel frames flexible — window and door sizes adjusted to need

Two-row windows — upper and lower windows ventilate and light

---

Disadvantages / Limitations

Glazing maintenance — large glass panels need cleaning and replacement

Door seals wear — large doors leak air and water over time

Brick infill heavy — masonry adds dead load to wall structure

Window reinforcement needed — openings need steel lintels and jambs

Thermal loss — large glass areas lose heat in winter

---

Typical Applications

Production factories — natural light for production floors

Warehouse loading doors — large truck access doors

Office-mezzanine buildings — upper windows for office space

Showroom factories — glass walls for product display

Cold storage plants — insulated glass and door systems

---

Installation Notes

Steel window frames bolted to wall girts at openings

Door frames set in structural opening, leveled before glazing

Brick infill laid between door and window openings

Window sills slope outward for drainage

Door seals checked after installation
