uPVC composite door thresholds?
A threshold for traditional uPVC doors is located at the foot of the door itself to provide a weather tight seal from the elements. In previous years, uPVC door thresholds featured a solid piece of outerframe that went around the entire door, meaning you had no options but to step over a piece of plastic to gain entry to your home through the front door
or back door.
This was considered awkward for many homeowners over the years, but against the benefits of dramatically increased thermal efficiency over timber doors many opted for the threshold.
Since the introduction of composite doors many homeowners can now benefit from the convenience of a low aluminium threshold, but with excellent thermal efficiency properties due to new technology.
There are 3 different threshold options to choose from for Rockdoor Composite Doors. 1, Low Aluminium (suitable for open-in and open-out doors), 2, Slimline PVC or 3, Full PVC.
