Bifolds Plus 20 year guarantee


Thermal Efficiency

Your Bifolds Plus 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!’

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

Of course our bifold doors are fully weather rated by British Standards

*Our doors have been tested with Triple Glazed Units, and are well within the current Building Regulation L1 and L2
