Leading edge
How the leading edge plays a key role in ensuring every door shuts with a smooth, precise action.
A CLOSER LOOK SERIES
LEADING EDGE
In Series 1, we looked at the importance of Aluminium Reinforcing, a standout feature that gives Rockdoor its unmatched strength and durability and shows exactly why it’s a cut above the rest. Now, in Series 2, we’re focusing on another vital detail that often goes unnoticed but makes a big difference to the way a Rockdoor feels – the leading edge, which plays a key role in ensuring every door shuts with a smooth, precise action.
WHY DO WE USE A LEADING EDGE?
Sometimes it’s the smallest of details that can make the biggest of differences, and that is a perfect way to describe the ‘leading edge’ of a Rockdoor.
Rockdoors are designed with a chamfered leading edge on the vertical lock side of the sash, which ensures the door smoothly closes into the aperture.
The inner frame we use, which is exclusive to Rockdoor, features a subtle 1mm chamfered edge detail that allows the sash to comfortably pass through the 4mm air gap between the outer frame and sash, gently touching the brush pile on its way through.
So, when considering we recommend a 4mm air gap when installing the door, 1mm represents an extra 25% clearance when closing the door.
SMOOTHLY DOES IT
When you hear the perfectly smooth operation of a Rockdoor being closed, a lot of this is down to the leading edge of the door sash itself. It also ensures the brush pile we use maintains its peak performance for thermal efficiency.
A BIG DIFFERENCE TO HOMEOWNERS
Whilst it may only be a small exacting detail in the overall design of the door, the chamfered leading edge of a Rockdoor makes a big difference to homeowners, as it gives them a feeling of quality when closing the door.
LEADING THE WAY IN UNIQUE FEATURES
A leading chamfered edge is just one of many unique selling features that demonstrate that Rockdoor leads the way in premium and unique composite doors.
