Thermally rated steel doors are an essential component in modern building design, offering a robust solution for maintaining energy efficiency and enhancing security. These doors are specially engineered to reduce heat transfer, ensuring that buildings remain insulated against external temperature variations. The key feature of thermally rated steel doors is their ability to achieve low U-values, a measure of thermal transmittance, which significantly contributes to reducing energy costs and improving comfort levels within the building.
One of the standout products in our lineup is the Steeldor Thermal. This door is crafted with a 44mm thick leaf composed of high-tensile ‘Rustec’ steel sheets bonded with an insulated Rockwool core. This construction not only meets but exceeds the thermal efficiency targets set by government regulations, achieving U-values as low as 1.5 W/m²K. Additionally, these doors are available with various customisations including a full range of RAL colors and hardware options, making them suitable for both internal and external applications.
Thermally rated steel doors are not only about insulation; they are also designed to be durable and secure. The Steeldor Thermal doors, for instance, come with robust frames and high-security fittings such as Grade 13 stainless steel hinges and integral dog bolts. These features ensure that while the doors provide excellent thermal performance, they also offer top-notch security and stability, making them ideal for a wide range of applications including personnel doors and emergency exits.
Choosing thermally rated steel doors from Security Direct offers numerous advantages, both in terms of product quality and service reliability. Our doors are meticulously engineered to meet stringent thermal and security standards, ensuring that you receive a product that is both efficient and durable. The Steeldor Thermal, for instance, is developed to comply with the updated Building Regulations Part L, making it an ideal choice for any modern building project.
We offer a variety of thermally rated door options tailored to meet diverse needs. The Steeldor Thermal is perfect for general applications, providing excellent insulation and security. For environments requiring higher fire resistance, the Firedor series is an excellent choice. These doors are fire-rated up to E120 and are constructed with the same high-quality ‘Rustec’ steel and insulation, ensuring they provide both thermal efficiency and enhanced fire protection. Additionally, our Acoustidor range caters to areas needing superior sound insulation while also offering thermal benefits.
Our thermally rated doors come with several customization options, including various hardware, frame, and threshold choices. This flexibility allows you to select doors that precisely match your requirements, whether it's for aesthetic preferences or specific functional needs. Furthermore, with a lead time of just 10-12 days, we ensure that you receive your high-quality doors promptly, keeping your projects on schedule.
1. What are thermally rated steel doors? Thermally rated steel doors are designed to minimize heat transfer, thereby improving energy efficiency and comfort in buildings. They are constructed with materials and design techniques that achieve low U-values, making them effective at maintaining stable internal temperatures.
2. How do thermally rated doors improve energy efficiency? These doors reduce the amount of heat that escapes or enters a building, thereby lowering the need for heating or cooling. This reduction in energy usage translates to cost savings and a reduced environmental footprint.
3. Can thermally rated steel doors be customized? Yes, our thermally rated doors, such as the Steeldor Thermal and Firedor, can be customised in terms of size, color, hardware, and threshold options. This ensures that they can meet the specific needs and aesthetic preferences of any project.
4. Are thermally rated steel doors suitable for external use? Absolutely. Our doors are designed to perform well in both internal and external environments. They provide excellent insulation and security, making them ideal for use as personnel doors, emergency exits, and more.
5. How long does it take to receive a thermally rated door after ordering? The lead time for our thermally rated doors is typically 15-20 days, subject to manufacturing and stock availability. This quick turnaround ensures that your project can proceed without unnecessary delays.
