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

The Hörmann T30 H3-D Single-Leaf Door is a high-performance multifunctional steel door designed for applications where fire protection, thermal insulation, security, and everyday durability are important. Listed by Euro Prestige as a single-leaf fire-rated interior door, the H3-D is particularly well suited for connecting a garage with the living area of a home, as well as for other areas where additional protection from fire, smoke, noise, and unauthorized access is required.

The Hörmann H3-D is a practical solution for homeowners, architects, contractors, and property developers looking for a dependable T30 fire-rated door with multifunctional capabilities. Euro Prestige currently lists the single-leaf H3-D at $2,300.

T30 Fire Protection for Added Safety

One of the key features of the Hörmann H3-D is its T30 fire-retarding classification. T30 indicates a fire-resistance period of up to 30 minutes under the applicable testing conditions. Hörmann documentation describes the H3-D as a fire-retarding multifunction door with thermal insulation, making it an appropriate choice for locations where a fire-rated separation is required or desirable.

This makes the door particularly relevant for the transition between a garage and a home. Garages can present additional fire risks because of vehicles, fuels, electrical equipment, and stored materials. Installing an appropriately specified fire door can help create an important protective barrier between these areas.

Strong and Durable Steel Construction

The H3-D is supplied as a complete door element with its frame. Available technical documentation describes the door leaf as a 45 mm thick, double-skinned steel construction with 1.0 mm sheet thickness, mineral-wool fire insulation, steel reinforcement, and steel security bolts. The galvanized door leaf and frame are finished with a primer powder coating in a grey-white shade similar to RAL 9002.

This construction provides the combination of strength and durability expected from a professional steel door. The three-sided rebated door leaf and robust frame design also contribute to reliable operation and a solid fit when correctly installed.

Thermal Insulation

In addition to fire protection, the Hörmann H3-D provides thermal insulation. Product documentation gives a U-value of 1.7 W/m²K for the H3-D configuration.

Thermal performance can be particularly useful when the door separates a heated interior from an unheated or cooler garage. By providing an insulated barrier between spaces, the door can help reduce unwanted heat transfer while improving the overall comfort of the adjacent living area.

Optional Smoke Protection

Fire protection is not limited to flames. Smoke can spread quickly through a building and represents a major safety concern during a fire. The Hörmann H3-D can be specified with additional equipment for smoke-tight performance, including a retractable bottom seal or sealed aluminium bottom profile and an overhead door closer with profile cylinder. Documentation also states that appropriately configured H3-D doors are factory-labelled and supplied with documentation for smoke-tight performance.

When smoke protection is important, the exact door configuration, accessories, installation method, and applicable local requirements should be confirmed before ordering.

Additional Security Options

The H3-D can also be configured with additional burglary-resistance features. Hörmann documentation references DIN EN V 1627 WK2 performance for specified configurations and lists optional security components such as additional security bolts, a drill-resistant locking cylinder, and an aluminium security fitting. The documented WK2 performance applies to specific door configurations, including doors without glazing, and installation conditions can affect applicability.

For homeowners using the H3-D between a garage and living space, this additional security capability can provide another layer of protection.

Sound Insulation Options

The multifunctional design of the H3-D also allows for improved acoustic performance with optional components. Depending on the selected configuration, documentation lists sound-reduction values associated with a bottom seal, aluminium bottom profile, or threshold rail.

This can be valuable when the door separates a garage, workshop, utility area, or other potentially noisy space from the home.

Suitable for Multiple Wall Types

The Hörmann H3-D is designed for installation in several common wall constructions, including brickwork, concrete, gas concrete, and partition walls, subject to the relevant installation requirements.

This versatility makes the H3-D suitable for residential renovations as well as new construction projects where a fire-rated internal or connecting door is required.

A Practical Door for Garage-to-Home Access

A garage-to-house connection is one of the most important applications for a multifunctional fire door. The H3-D combines fire-retarding performance with thermal insulation and optional smoke, acoustic, and security features in a single door system.

Its steel construction, insulated 45 mm door leaf, complete frame, and available safety accessories make the Hörmann T30 H3-D Single-Leaf Door a practical option for projects that require more than a standard interior door.
