Description

Steeldor Thermal has an exceptionally low U-Value of 1.5 W/m²K and has been added to the Strongdor range to address the growing demand for thermally proficient, insulated. Comprising of 1.2 mm ‘Rustec’ steel sheets, the leaf skins are mechanically interlocked and internally bonded, proving greater stability and protection against de-lamination.


Thermal Doors for Commercial Use

Opting for thermal steel for your commercial doors enhances the building's performance by improving its U-value and reducing the risk of thermal bridging compared to standard steel doors. The inherent strength of our thermal personnel doors makes them particularly well-suited for industrial facilities and high-traffic areas, offering both durability and energy efficiency.


Thermal Doors for Residential Specification

While steel doors may not traditionally be the first choice for residential applications, they can be an excellent option for lobby entrances, service areas, and utility spaces. Steel doors offer superior durability compared to many other materials, making them particularly well-suited for high-traffic communal areas and high-rise properties. With a selection of 150 available colours, Strongdor steel doors can be tailored to meet both functional and aesthetic requirements, providing a long-lasting and versatile solution.


Features and benefits:

  • Available in single, double and door and a half configurations.
  • Individually built to order and constructed.

  • 150 RAL colours as standard.
  • Easy to install.
