Bi-fold Door Thermal Efficiency

Origin’s Bi-fold doors will keep you warm when it’s chilly, and cool when it’s hot.

With a Certified U Value of about 1.3 W/m2K* we surpass the British Building Regulations by an industry leading 27%. This gives you more design flexibility on bigger projects, keeps your energy bills low and helps you to ‘stay green!’

Origins uncompromising design has included the most advanced thermal breaks, weather tight seals and locking mechanisms that ensure maximum compression for increased weather resistance.

Of course our Bi-folding doors are fully weather rated by British Standards.

*Origin have had our doors tested with Triple Glazed Units, and we’re well within the current Building Regulation L1 and L2, even with standard double glazed units.
