Why This Series

Engineered for Every Detail

Every aspect of the 112SD Series is designed to deliver reliable performance, safety, and long-term value.

112mm Deep Frame

The widest profile in the GBT range — the 112mm depth provides the structural capacity required for large, heavy door sashes that would not be possible with narrower profiles.

DGU-Exclusive Design

Engineered specifically for double-glazed units — both standard and wide 32mm configurations — ensuring every 112mm door installation delivers premium energy performance.

???

Superior Thermal Barrier

The wide 112mm frame combined with mandatory DGU glazing delivers an exceptional thermal barrier — significantly reducing heat transfer between interior and exterior spaces at door openings.

Heavy-Duty Hardware Ready

The thicker 2.2mm walls and wider frame depth provide robust anchoring for multi-point locking hardware, security handles, and heavy-duty roller systems required by large door sashes.

100% Lead-Free

Calcium-zinc stabilized compound throughout — no lead in any component. Safe for every residential and commercial application, including healthcare and children's facilities.

Zero Maintenance

The uPVC door frame requires no painting, sealing, or wood treatment — ever. Resists moisture, termites, and UV degradation for 15+ years of trouble-free operation.

Manufacturing Technology

Door-Optimised Co-Extrusion

The 112mm Sliding Door Series is produced on dedicated extrusion lines calibrated for door-grade profiles. Larger cross-sections demand tighter extrusion speed control to maintain the ±0.2mm tolerance throughout the full 112mm profile depth — a manufacturing challenge that GBT's equipment is purpose-built to meet. Colour co-extrusion is applied at the same stage for a molecularly bonded finish.

Where It Works Best

Ideal Applications

The 112mm Sliding Door is the preferred choice for a wide range of residential, commercial, and institutional projects.

Residential

Patio & Garden Sliding Doors

Connect living rooms and dining areas directly to garden patios and terraces. The wide 112mm frame handles heavy glazed sashes smoothly and maintains a clean sight line at the opening.

Multi-Storey Residential

Balcony Access Doors

The 112mm profile provides the structural integrity needed for balcony sliding doors in multi-storey buildings — resisting wind loads, thermal cycling, and the demands of daily operation.

Premium Villas

Glass Wall & Full-Height Sliders

Premium villa developers specify the 112mm series for full-height glass wall systems — multiple sashes in a single run creating near-seamless transparency between indoor and outdoor spaces.

Commercial & Hospitality

Hotel Rooms & Banquet Areas

Hotels and banquet venues use the 112mm sliding door to create flexible room-to-outdoor connections. DGU glazing maintains acoustic separation and thermal comfort for guests.
