My door/window has not got the correct sized frame

The door- and window frames are delivered with a standard channel for both 28 and 44 mm. Upon delivery all frames are set to a 28 mm channel. In case your summerhouse is manufactured in 44 mm wall thickness, you have to follow the next steps.

1. Unscrew the upper profile from the frame.

2. Next flip over this profile and re attach it.

3. You repeat this for the lower profile.

4. Next you do the same for the side profiles, one at a time.

5. In case of the doorframe first turn the upper profile. And then exchange the left and right profiles flipping them over at the same time.
