Hörmann H3-G T30 Single-Leaf Fire-Rated Interior Door

When fire safety, durability, and professional European engineering are essential, the Hörmann H3-G T30 Single-Leaf Fire-Rated Interior Door provides a dependable solution for modern residential, commercial, and architectural projects. Designed as a robust steel fire door, the H3-G combines 30-minute fire resistance with a clean, functional appearance suitable for a wide range of interior applications.

Available through Euro Prestige, this German-made Hörmann fire-rated door is designed for projects where reliable fire compartmentation and long-term performance are important. The product is listed with an EI₂ 30 / H3-G resistance classification and is available as a single-leaf configuration.

30-Minute T30 Fire Protection

The primary advantage of the Hörmann H3-G is its T30 fire-retarding performance. Hörmann documentation states that the H3 G fire door can provide a fire resistance period of up to 30 minutes, helping limit the spread of fire and providing additional time for occupants to respond during an emergency.

For buildings where fire-rated doors are required between designated areas, corridors, utility spaces, technical rooms, or other protected zones, selecting a properly specified and installed fire door is an important part of the overall fire-safety strategy.

The H3-G is intended for installation in interior walls, with Hörmann specifying its use as a steel fire door with the appropriate approval for internal applications.

Strong Welded Steel Construction

The Hörmann H3-G is engineered for durability. Its welded steel construction incorporates a 65 mm thick door leaf manufactured from 1.5 mm sheet steel. This robust construction provides the rigidity expected from a professional-grade fire-rated door while supporting dependable everyday operation.

The door leaf incorporates mineral-fiber insulation, while the steel surface is galvanized and given a primer coating in a light gray-white finish similar to RAL 9002. The design creates a practical appearance that works well in commercial interiors, institutional buildings, apartment projects, and modern architectural environments.

Optional Fire-Rated Vision Panel

Fire protection does not necessarily have to mean sacrificing visibility. The Euro Prestige specification lists an optional vision panel with fire-rated glass, allowing the H3-G configuration to be adapted when visual connection or light transmission between spaces is desirable.

This can make the door particularly useful in environments such as office buildings, corridors, commercial properties, public buildings, and other areas where visibility is valuable. The exact glazing configuration should be specified according to the applicable Hörmann system requirements and project regulations.

Large-Format Single-Leaf Design

One notable feature of the H3-G is its suitability for larger openings. Hörmann's technical documentation lists H3 G-1 nominal ordering widths from approximately 875 to 1500 mm and heights from 2500 to 3250 mm, making it particularly useful where a conventional standard-size fire door is not sufficient.

The large-format capability can be valuable for architectural projects, commercial buildings, industrial environments, and other applications requiring a wider or taller single-leaf opening.

Installation requirements depend on the supporting wall construction. Hörmann documentation specifies compatible substrates including masonry, concrete, aerated concrete blocks or panels, and certain prefabricated walls, with minimum substrate thicknesses depending on the installation type.

Additional Smoke Protection Options

The H3-G can also be configured with additional performance characteristics where applicable. Hörmann documentation identifies smoke-tight performance as an additional function available with corresponding equipment. This makes it possible to specify the door more closely according to the requirements of a particular building and fire-safety concept.

Because fire and smoke protection performance depends on the complete door assembly, including the frame, hardware, seals, glazing, wall construction, and installation, the final configuration should always be selected according to the manufacturer's approved specifications and applicable building regulations.

Ideal Applications

The Hörmann H3-G T30 fire-rated interior door can be considered for a variety of applications, including:

• Commercial and office buildings
• Apartment and residential developments
• Corridors and circulation areas
• Technical and utility rooms
• Public and institutional buildings
• Architectural and renovation projects
• Large interior openings requiring a single-leaf fire door

Its combination of steel construction, T30 fire protection, large-format dimensions, and optional vision-panel configuration makes it a versatile choice for projects where safety and architectural requirements need to work together.
