Replacing Velux GGL Loft window only

Hi 

 

Hope your all good

 

As the title suggests my loft window needs to be replaced.

 

Was hoping to just replace the window part only keeping the existing flashing and frame in place.

 

Wanted to know if the following models will be compatible with my window to save on costs.

 

Centre Pivot Loft window - 78 cm x 118cm

 

Current window:

GGL - M06 - 3509

 

Alternatives:

GZL - MK06 - 1051

 

From research the only difference between GGL and GZL is a the addition of a ventilation flap

MK06 is an updated M06

 

MY question is, will the GZL - M06 windows fit the current frame perfectly

 

or does the exact same model etc need to be ordered..

 

Hope to hear from you soon

 

Thanks in advance

Sorted, The GZL is not compatible with GGL. When replacing the Sash ( Window only ) Exact model is required
