Hörmann Thermo entrance doors: energy efficiency and security you can feel from the very first step.
The Hörmann Thermo range represents an evolution in entrance doors: it’s no longer just about protecting the home, but about optimizing it. These doors are designed for those who demand maximum thermal comfort without compromising on security, aesthetics, or durability. Thanks to their construction with a rigid foam insulating core and a high-strength steel door leaf with no visible profile, Thermo doors achieve exceptionally low thermal transmittance values. This translates into real energy savings, greater indoor comfort throughout the year, and an entrance that acts as a true barrier against cold, heat, and noise.
Designed for demanding climates or homes committed to energy efficiency, these doors don’t just meet expectations—they exceed them. They help reduce heating and air-conditioning consumption, prevent unwanted drafts, and effectively insulate against external noise. All of this comes without sacrificing visual appeal: available in a wide range of designs, colors, and configurations, Thermo doors integrate elegantly into any architectural style, from the most modern to the most traditional.
Security is also a core pillar of this range. Equipped with multi-point locking systems, concealed hinges, and smart access options, Thermo doors provide solid protection against intrusion attempts without sacrificing the comfort of smooth, effortless operation. Every component is designed to last—even in areas with high humidity or intense sun exposure—maintaining performance and aesthetics intact over time.
In short, a Thermo door is not just an entryway—it’s a conscious decision that enhances quality of life at home. Because shutting out the cold is only the first step toward a more efficient, more comfortable, and more protected living space.
Superior thermal insulation.
Thanks to their steel door leaf with a high-density rigid foam core and a design with no visible frame, Thermo doors achieve very low thermal transmittance values. This results in an entrance that actively helps maintain indoor temperature, reduce energy consumption, and enhance comfort in every season.
Enhanced security as standard.
The Thermo range incorporates multi-point locking systems, concealed hinges, and advanced options such as high-security cylinders or smart controls. All of this ensures solid, discreet protection that turns the door into a true stronghold of the home—without affecting its aesthetics.
Modern, customizable aesthetics.
With clean lines, elegant finishes, and a wide variety of styles, colors, and decorative elements, Thermo doors adapt perfectly to all types of homes. Their high-resistance finish keeps the look impeccable over time, even in demanding climatic conditions.
High efficiency at a competitive price.
Thermo doors deliver technical performance typical of premium ranges, but with a value-for-money ratio that makes them a highly attractive choice. A smart option for discerning homeowners who value efficiency, design, and security—without paying more than necessary.
Technical details
Insulating technology, robust construction, and German precision in every millimeter.
Hörmann Thermo doors are specifically designed to deliver exceptional thermal insulation. The door leaf, with no visible external frame, is made of galvanized steel and a high-density rigid polyurethane foam core, available in thicknesses of up to 65 mm depending on the model. This allows thermal transmittance (U-value) ratings as low as 0.87 W/(m²·K), significantly exceeding energy efficiency standards for residential entrance doors.
Multi-point locking system and enhanced security.
Each Thermo door comes standard with a multi-point locking system of up to five points, featuring solid bolts and concealed hinges that enhance anti-burglary protection without affecting the design. In addition, they can be configured with RC 2 or even RC 3 security options, complying with European standards for resistance to intrusion attempts.
Excellent weather tightness and acoustic insulation.
High-quality rubber seals around the entire perimeter of the door leaf provide effective protection against wind, rain, dust, and drafts. This results not only in improved thermal comfort, but also in a noticeable reduction of external noise—ideal for homes located in urban areas or environments with high acoustic exposure.
European certification for your peace of mind.
All Thermo doors comply with European standard EN 14351-1 for external doors, including requirements for thermal insulation, water tightness, wind resistance, and durability. This certification guarantees optimal performance for years, even under demanding environmental conditions.
