A Simple Guide to Folding Terrace Doors Prices

It all depends on your customer’s needs and budget. If they do not mind the drawbacks, such as:

• the rather high price
• lower thermal and noise insulation compared to other terrace doors
• sporadic jamming while opening or closing the door
• the absence of a threshold that allows for the potential entry of excessive water into the room
• the installation process that is prone to be performed incorrectly

and care more about their pros, e.g.:

• wide and unobstructed openings, that create a seamless connection between indoor and outdoor spaces
• versatility of design 
• their aesthetics and curb appeal
• space efficiency, as folding windows serve as a great space-saving solution

then folding doors may be worth a shot. 

Are folding doors a good idea?

As we stated before, folding doors are a sensible choice if the customer values abundant natural light and unobstructed views, and wants to create a smooth passage between spaces. If they enjoy outdoor living or hosting gatherings, bi-folds can greatly enhance their experience – especially if their estate is located in warm climates, where the lower thermal performance won’t be a big problem.

Why are folding terrace doors so expensive?

In a nutshell: the complexity of their design and the additional hardware required for their operation contribute to higher costs. Since folding terrace doors are designed to fold and stack neatly to the side, they require intricate engineering and precise manufacturing to ensure smooth usage and durability.

In short:

The most affordable option for bi-fold doors is typically UPVC, which can range in price from £1000 to £4000. As an illustration, a white 4-panel bi-fold door with dimensions of 3090 × 2090 mm would cost approximately £2320.

• if the colour is changed to e.g. black or green the price goes up to £2770
• it’s the same with panels, if a door has 5 instead of 4, it will increase in size and cost £3650

Wooden bi-fold doors are indeed more expensive, typically ranging from £2000 to £5500. For example, a 3-panel oak folding door with dimensions of 2700 × 2100 mm would cost approximately £2529.

In short:

When it comes to aluminum, such windows start from £2500 up to £6000 and with customization (e.g. finishes, fittings) comes additional cost. For example, a white 3-panel 2000 × 2000 m costs £2525.

Are folding terrace doors cheaper in Poland?

Definitely yes, for example, you can get a So Easy Decalu 88 aluminum bi-fold door with 2 or 3 panes and a max 2.8 m sash size for around £1405 or Cortizo Bi-Fold with 2–3 panes and a max 3 m sash size for £1733.

These doors not only offer competitive prices, but also are top-quality products that incorporate the latest European technologies.

When considering the same size of the structure, adding another sash typically incurs an approximate surcharge of 10% of the original price. Opting for a bicolour option carries an additional cost of around 3% of the initial rate. As for a low threshold, there is usually no surcharge or a maximum of 2% of the original expense involved.
