French Doors

Sheerframe French doors can be made either outward opening or inward opening.  Requirements for restricted opening and safety doors can also be accommodated in the designs.

They are compatible with other Sheerframe window and curtain walling systems and can come with standard or low thresholds.  However, low thresholds are not recommended in high-exposure locations.

Low U values down to 1.6W/m2K can be achieved to exceed Part L of the Building Regulations.
