Strong thermal performance and security
RD70 is designed for strong thermal performance and security, making it well suited to main external doors. SD70 provides a slimmer, heritage-style alternative, offering refined sightlines for design-led applications.
This allows doors to be selected based on both performance requirements and the overall look of the project.
