Mullion Posts

Double Glazed Sections


Mullion posts and gaskets.

PRO-office DG double glazed system currently offers the option of an aluminium mullion post or a plastic mullion gasket, depending on your projects requirements.



Blinds or No Blinds

If you intend to install integral blinds, you have the option to use our aluminium mullion post, which allows you to create a very stable way to hold the glass. This mullion post conceals the blind control cable kit keeping it hidden from the end-user. Fixing the control knob to the surface of the mullion post affords a sleek finish. We stock this mullion post in 4 different colours. However, we are happy to custom paint this section in any of the RAL colours available.

If you are looking for a more seamless or frameless aesthetic and do not intend to use integral blinds, our extruded plastic mullion post is ideal. The mullion post is made from clear plastic allowing for a translucent finish once combined with double glazed glass panels. Technical manuals detailing the best method in which to install both types of mullion posts are available.



In Summary

Our mullion posts allow you to install integral blinds or provide a clear, seamless finish for your glass partition. With two options and excellent stock availability, we offer practical solutions which benefit from simple installation.
