How to measure for new doors and windows - step by step
Before you start, have the following ready: paper and pencil, a tape measure and possibly a spirit level if it is an older house.
Grab your paper and pencil and measuring tool
Always measure from the outside. Start with the width, then the height.
Measure more than one place from brick to brick. The opening in the wall might be slightly skewed, which is why you should use the smallest measurement.
Now you have the hole measurements. To find the frame dimensions, subtract 2.5 cm from the hole measurements. This leaves a gap of around 1.25 cm in each side for sealing and insulation.
Use the frame dimensions/measurements to order your Klar windows.
What's the difference between hole measurements and frame measurements?
Hole measurements are the measurements from brick to brick. Conversely, the frame dimensions are the measurements of the particular door or window element. You should always start with the hole measurements because you need space for insulation. The difference between hole and frame dimensions are approximately 2.5 cm in each dimension.
Facadetype
To get the right measurements, please check the facade of the house. A wooden facade often has a sheating that covers part of your existing window and are simple to dismantle to get the outer measurements of your frame.
