A window sill guard bar is mounted in one of two distinct ways, depending on whether discretion or ease of fitting matters more. Both terms — “reveal-mounted” (en tableau) and “face-mounted” or “facade-mounted” (en applique / en façade) — are the ones actually used in the ironwork and guard-rail trade.
Reveal-mounted
The bar is fixed inside the window reveal, on the sides of the opening between the outer wall face and the window frame. The fixing points are therefore invisible from outside once the bar is in place.
Face-mounted (on the facade)
The bar is fixed on the outer wall, over the opening, directly onto the facade. The fixing points remain visible, but fitting is generally faster and works on more wall types (including when the reveal isn’t in good enough condition for a hidden fixing).
How to choose
The choice depends on several factors to weigh case by case:
- The condition and thickness of the reveal — a reveal-mounted bar needs masonry sound and thick enough to anchor the bar securely.
- The look you want — full discretion (reveal-mounted) or a visible, straightforward fixing (face-mounted).
- The type of facade — stone, render, brick: each surface has its own anchoring constraints, to be confirmed by the professional fitting the bar.
The mounting method is one of the details asked in our quote form — if you’re not yet sure which suits your window, the professional contacted can advise after an on-site survey.
Frequently asked questions
Is reveal-mounting always possible?
No, it requires a reveal (the embrasure) in masonry thick and sound enough to anchor the bar securely. An on-site survey can confirm this.
Is one method stronger than the other?
Both methods, properly carried out on a suitable surface, hold reliably. The choice is mainly about the look you want and the condition of the surface, not a difference in strength as such.
Can I change my mind after the quote?
The mounting method affects the measurements taken and sometimes the price — better to settle it with the professional contacted before fabrication rather than after.
