They are Customisable

Build uPVC bi-fold doors your way by picking and choosing from our portfolio of exquisite colours and foils. Contemporary and traditional styles are fully achievable when you choose Hertford Glass as your installer.

Add a woodgrain foil if you want to replicate the authentic appearance of wood. Alternatively, keep your frames white and embellish them with silver or chrome handles to create an impactful modern design.

They Open Almost Fully

uPVC bi-fold doors open to near threshold width. Because they collapse into a concertina shape to the side of your home, no visual obstructions are presented.

The extensive use of glazing used throughout each bi-fold design means your room will be flooded with light and your spaces seamlessly connected.

The combination of lots of glass and a wide access point make uPVC bi-fold doors the perfect choice – whether you’re entertaining or relaxing inside.

Energy Efficient

Keeping your home warm and comfortable year-round is important. Our range of uPVC bi-fold doors is fitted in each case with market-leading features designed to keep the heat in and prevent cold air out.

Add uPVC bi-fold doors into your design mix to experience more than improved aesthetics. Aside from making your home, conservatory or extension warmer, your new installation will reduce your heating costs and carbon footprint

They Improve Security

uPVC bi-fold doors fitted by Hertford Glass are each equipped with high security locking systems capable of repelling almost all attempts to gain access to your home illegally.

Because uPVC is incredibly strong, your installation will also stand up well to hard impacts – caused either by extreme weather conditions or intruders trying to gain entry.

The safety features built into each of our bi-folds will, in most cases, prevent injuries caused through improper operation. Contact us for more information about this feature.
