Low Threshold Doors
Achieving high levels of air and water tightness, dust protection, insect resistance, and sound reduction generally requires effective sealing around the complete perimeter of the door sash. However, conventional high thresholds can sometimes affect accessibility and everyday convenience. Modern fenestration therefore needs to balance performance, ergonomics, and practical living requirements.

However, conventional high thresholds can sometimes affect accessibility and everyday convenience. Modern fenestration therefore needs to balance performance, ergonomics, and practical living requirements.
ENCRAFT offers aluminium low-threshold solutions wherever technically suitable, helping provide easier access while maintaining the functional requirements of the door system. Where a low-threshold or threshold-less configuration is not practical, ENCRAFT can also provide guidance on ground-level preparation and floor detailing to minimise the visible upstand associated with Fold & Slide Patio Doors and Tilt & Slide Patio Doors.
For enhanced durability and long-term performance, ENCRAFT uses aluminium thresholds with a silver anodised finish. This provides a robust and hard-wearing foundation designed to withstand regular use while maintaining the overall appearance and functionality of the door system.
Frequently asked questions

Not if the profile is UV stabilised and lead-free, which ours are. Yellowing happens with cheap unstabilised profile or recycled material. We supply a written warranty against discolouration.
An acoustic laminated inner pane inside a double-glazed unit, with the two panes at different thicknesses and a wide cavity. Just as important, choose a casement or tilt-and-turn window rather than a slider, because the sash needs to compress onto its gaskets to seal.
Yes. We bend profile on a heated forming table from a site template, so semi-circular, segmental and elliptical heads are all possible, fixed or with an operable lower sash.
