Window and door jamb extensions

Customer asks:

What are window and door jamb extensions, and when do we use them?

Aru Grupp answers:

A jamb extension is an extra part for a window or door that helps it fit the wall thickness. We make the extension exactly to match the wall and opening size, so the window or door fits perfectly. Using the right jamb extension ensures proper installation, improves insulation, and gives a neat, even finish.

Jamb extensions are especially important when the wall is thicker than usual, like in older buildings. The right extension also helps create a clean and uniform look.

Jamb Extension Options

We cannot use the same jamb extension for every window or door because openings are different. Extensions have different designs, but we can make them in different widths. Even in the same project, extensions may have different widths – for example, in a sauna, the walls have extra insulation, so the windows need wider jamb extensions. In these cases, we make the extension exactly to the opening size and need.

Customers don’t need to worry – our project managers can recommend the right jamb extension for each product. The most important thing is to know the exact wall thickness and opening measurements so installation goes smoothly and the result looks perfect.

Who can help?

The best way to choose the right jamb extension is to contact our project managers with your project. Experienced specialists check the type of windows and doors, wall thickness, and the whole project to make sure the result is correct and attractive.
