Window grillwork has been a traditional architectural element present in different époques throughout centuries. Grills used to be made from iron and they were not only ornamental but also durable, providing additional security to people’s houses.
Nowadays with hi-tech security systems, iron grills’ main function as a burglar protection is becoming obsolete, although you may still find neighborhoods where such grills are present.

Window grills make your house facade stand out from the rest of the neighbourhood and you can create a unique custom look by choosing the desired layout.
Interior window grills are simply decorative bars which are located in between window panes. Since they are inside the glass unit, they do not make impediment to cleaning and also do not require any special maintenance. Interior grills can have various layouts. When we talk about window grill layout we refer to the position of the bars inside the sealed glass unit.
Among some most common bar configurations there are prairie, colonial, diamond, and custom grills.
Prairie grills, also called perimeter grills are bars around the perimeter of the window. They acquired the name “prairie” after their popularity during the Prairie School architecture period in the late 19th – early 20th century.
Colonial grills represent a classic grill layout which is suitable for virtually any architectural style. Being the most versatile and universal grill pattern, it can be customized to include 4 to 12 lights depending on the window size. Also, if you have a hung window, for example, you may choose to add colonial grills in either top or bottom sash only. Colonial grills are often added to casement windows, as well as bay and bow windows.
In diamond grills the bars are positioned in such a way that they form diamond shapes. This type of grills adds an interesting accent to your house architecture.
For customers who prefer curved or ornate lines in window grills, fancy designs are available.
Exterior grills (SDL)
For those people who want to achieve a historic appearance of their windows (in the past windows consisted of individual glass pieces assembled within a wooden grid frame), there is an exterior grill option called simulated divided light (SDL) grills. Such grills are placed on the outside of the glass unit thus creating an imitation of a historic pattern.
