3 Leaf Bi Fold by Mazuli

Glazed and Unglazed Systems

Glazed Systems

The glass our suppliers provide with their bi fold systems is 4mm planitherm total + 20mm thermal warm edge spacer bars with argon gas cavity. The total overall u value = 1.2W/m2k. If this isn’t suitable for your project then we can arrange alternative solutions with better U values from our glaziers. We also offer Integral Blind units.

Unglazed Systems

ALL bifolds are prepared for a glass unit thickness of 28mm overall as standard. If you are purchasing IGU’s yourself then please state this when ordering or let us order them for you.

If you are sourcing your own glass then please ensure the glazing meets the required Building Regulations. Door glass must be toughened or laminated safety glass to pass Building Control regulations.

We can take no responsibility for any glazing / building regulation failures that occur from self sourced glazing units.
