What are timber reveals?

In straightforward terms, a reveal refers to the timber framing around a window or door (commonly recognized as a windowsill at the bottom of windows). Timber reveals play a crucial role in properly fitting the window or door into the opening, while architraves are affixed to the reveal to conceal the gap created by the plasterboard. While reveals offer practical benefits, it’s important to note that their suitability may vary depending on construction type or individual preferences for each specific project.

What timber reveal size do I need?

The size of reveals you need, if any, depends on the construction you are using for the build, while we can offer custom reveals cut to the size you prefer, the following is the basic rule of thumb we use when determining which reveal is right for you.

This depends on the construction you are using for the build and the stud sizing. For example if you are building with Brick Veneer with a 70mm or 90mm stud, you would use either 116mm or 140mm reveals respectively. Or perhaps you are building a timber/cladded house? Well that would mean 80mm or 100mm reveals, again respectively.

What if you are building out of blockwork? Well usually we would take the fins off the windows that the reveals normally attach to and not allow for reveals, this allows the window to be positioned without the timber surrounding the window

Cavity Brick Veneer (70mm/90mm Studs):

In the case of a Brick Veneer structure, we recommend utilizing 116mm(70) or 140mm(90) pre-primed reveals in conjunction with traditional architraves.

Weatherboard/Cladded (70mm/90mm Studs):

In the context of a Weatherboard or Cladded building, our recommendation is to opt for 80mm(70) or 100mm(90) pre-primed reveals when incorporating traditional architraves.


In the case of Blockwork, reveals are typically omitted, and the windows undergo a process where the fins are removed, and the product is angle fitted.

In conclusion, timber reveals serve as essential components in the construction and finishing of windows and doors. These wooden frames not only contribute to the structural integrity of the installation but also play a crucial role in enhancing the aesthetic appeal of a building. Timber reveals, found surrounding windows and doors, provide a practical solution for fitting these elements into openings, and their integration with architraves helps achieve a seamless and polished look.
