First, material choice is key to ensuring durability and consistent performance. Steel doors made from corrosion-resistant materials like Magnelis steel off er excellent impact resistance and durability, allowing them to withstand heavy use and knocks without compromising performance. Unlike timber doors, which can weaken at joints or degrade over time, steel doors maintain performance because they are less susceptible to wear, moisture damage, and deformation. Backed by a 10-year anti-corrosion warranty, Magnelis steel doorsets provide added assurance that the doors will not degrade prematurely and will remain in excellent condition long term. Where security is a priority, doors can
act as the fi rst line of defence, controlling who enters and exits by meeting relevant security standards to resist forced entry. Security doors that meet PAS 24 (2022) or LPS 1175 standards provide confi dence in the door’s ability to resist forced entry using tools or sustained methods of attack. Steel doorsets can also meet specifi c
fi re-safety requirements, providing the appropriate level of fi re resistance. For example, ELITE-DOR can off er PAS 24 (2022) certifi cation combined with up to two hours of fi re resistance and 1.5 W/ (m²K). Where thermal performance is a priority, ELITE-DOR achieves a U-value as low as 1.3 W/(m²K), exceeding the 1.6 W/ (m²K) requirement as set out in Approved
Document L of the Building Regulations. ELITE-DOR combines two popular steel door ranges, OUTA-DOR and SECUR-DOR 2.1, into one fl exible solution, allowing specifi ers to tailor the doorset to meet a project’s specifi c requirements. Meeting evolving building performance requirements Today, doors are expected to meet multiple performance needs, providing a solution that not only resists attack but also meets thermal, fi re and compliance requirements. Steel doors can improve indoor comfort, reduce energy demand and meet broader performance requirements when specifi ed with the right insulation, security and fi re ratings. To ensure the doorset performs as intended and maintains performance, it is also important to consider the entire doorset and how each component works together.

achieve low U-values because its dense structure traps air, creating a thermal barrier that prevents heat from escaping, retains warmth in winter, and reduces overheating in summer. Steel doorsets that achieve low U-values
off er several benefi ts, including improved energy effi ciency, reduced heat loss, lowered heating costs and compliance with building regulations. The wider role of steel doors Depending on the building and its intended use, doors may also need to meet requirements for fi re resistance, security, acoustic performance, durability and accessibility. Modern security steel doors can carefully balance these wider performance requirements with thermal performance, so specifying the correct doorset is crucial.
