The Aluminium SlimLine 38 external door extends the SlimLine window system to door applications, providing an external door solution with the same exceptionally slender profiles that make the SlimLine 38 the preferred choice for heritage renovation and steel-frame replacement projects.
Where planning requirements or architectural briefs demand that the slim sightlines of an original steel-framed building are preserved, the SlimLine 38 external door delivers a fully thermally broken, high-performance aluminium door that respects those proportions while meeting modern standards for weather resistance, security and energy efficiency. This makes it an indispensable part of any whole-building steel-frame replacement project where all fenestration — windows and door alike — must conform to the original visual character.
Available in inward and outward opening configurations, with matching SlimLine 38 window profiles to maintain consistent sightlines across the complete building elevation.
A range of finishes specifically suited to heritage and contemporary contexts — anthracite, black, silver grey, bronze and other metallic options that closely replicate traditional steel window coatings. Multi-point high-security locking is standard. The profile can be combined with the CS 77 door system for projects specifying both standard and slim-sightline doors across the same development. Visit our External Door Showcases to see the Aluminium SlimLine 38 installed in completed heritage renovation projects.
