DescriptionHormann TGT HG-L Underground Garage Rolling Grille
The Dedicated Solution for High-Traffic Residential & Commercial Parking
The Hormann TGT HG-L is a specialist rolling grille system engineered specifically for the demanding environment of underground and collective car parks. Unlike standard roller shutters adapted for this use, the TGT is built from the ground up to handle high-frequency operation—capable of up to **300 cycles per day**—making it the ideal entrance control solution for residential apartment blocks, office car parks, and mixed-use developments.
Its compact design requires just 350mm of headroom, allowing it to fit into low-ceilinged entrances where other commercial doors would fail. The robust construction is designed for a service life of over 200,000 cycles, ensuring long-term reliability with minimal maintenance.
Optimised for Ventilation and Airflow (UK Compliance)
In the UK, enclosed car parks must meet strict building regulations (Approved Document F) regarding ventilation to safely disperse vehicle exhaust fumes and prevent the buildup of carbon monoxide and flammable vapours.
The HG-L Aluminium Grille curtain provides a free ventilation cross-section of approximately 85% of the door surface. This high level of permeability allows for:
- Natural Cross-Ventilation: Often removing the need for expensive mechanical extraction systems in smaller car parks.
- Smoke Clearance: Assisting in the rapid venting of smoke in the event of a fire, aiding safe evacuation.
- Air Exchange: Ensuring a constant flow of fresh air to meet health and safety standards for users.
Smooth, Safe, and Quiet Operation
Noise pollution is a critical concern for residential developments. The TGT system features **Optimised Operator Systems** (WA 300 R S4) with "soft-start" and "soft-stop" technology. This ensures the door opens and closes whisper-quietly, preventing disturbance to residents living directly above the garage entrance.
Crucially, the standard power limit in both the "Open" and "Close" directions means the door is inherently safe. For most standard sizes, it **does not require a sensitive bottom edge or safety photocells**, which are often the first components to fail in dirty car park environments. This wear-free safety technology significantly reduces downtime and repair costs.
Permanent Protection & Security
The system is built to last. The operator and curtain mechanism are fully enclosed in a galvanised steel housing as standard, protecting moving parts from dust, dirt, and tampering. To prevent unauthorized entry by small animals or the accumulation of street litter, an optional 640mm high marten protection section can be fitted to the bottom of the grille.
ApplicationResidential Apartment Blocks
The TGT is the gold standard for underground parking in apartment complexes. Its quiet operation ensures residents aren't woken by the door opening, while its high cycle rating handles the frequent flow of tenants.
Office Car Parks
Perfect for staff parking areas that see intensive use during morning arrivals and evening departures. The reliable WA 300 operator ensures no queues form due to slow operation or breakdowns.
Mixed-Use Developments
For buildings combining retail and residential spaces, the HG-L grille offers the necessary security separation without compromising the building's fire strategy, allowing smoke and fumes to vent naturally.
Restricted Height Entrances
Many older buildings or city-centre basements have very low ceilings. The TGT's unique tension spring assembly allows it to fit into just 350mm of headroom, often the only powered solution that will fit without major structural work.
