Accoya is modified timber which has been through a process called acetylation, a patented technology which gives the timber enhanced properties, making it a ‘super timber’. Accoya has the ability to resist rot, combat the elements and will continue to be reliable for decades.

European Oak simply has a uniform colour and grain, this gives it the traditional warming appearance customers expect and is of very high quality. Other companies may use American White Oak, this type of oak is normally only used for internal furniture and joinery as it is less durable. The appearance of American white oak can vary in colour, therefore, in order to make it more uniform the wood needs to be stained, this can in some cases, create an unnatural look.

We use the E3 from Centor, this is a medium-heavy duty bi-folding door system that allows our bi-folds to continuously operate effortlessly. The E3 is Centor’s solution to the challenge of creating seamless transitions between indoor and outdoor environments. The E3 is the leading bi-folding door system for double glazing as it takes into account the extra weight of double glazing, ensuring the tracks function smoothly each and every time. Our doors promise unprecedented insulation against noise and temperature variation when closed. The E3 also enhances security and resistance of the elements, even in the most exposed applications.

There are many cheaper alternatives in the market, such as Centor’s E2, however we value quality with longevity and the prolonged improvement in our client’s lifestyles. We design your bifolds so they work for you, not against you. It shouldn’t take a wrestling match for them to open or close, even after a number of years. It is the upmost importance to us that our doors smoothly glide open and close each and every time with the simple push of a finger.

Thermal transmittance (U-value) is the rating of how effective a product or material is as an insulator, it’s measured by W/m²K to produce a U-value. The lower the U-value is, the better the thermal insulator.

Argon filled glass has Argon in the glazing cavity instead of normal air like in standard glazing, which provides greater thermal efficiency by reducing the ability of heat transfer through the pane, keeping your room at a more stable and desirable temperature, regardless of the external weather conditions.

Our products are factory glazed then enclosed into our specialist packaging, this is sectioned by components, in order to make installation as simple as possible.

We offer both, you can either choose from our more popular standard sections or you can scroll down to create your own bespoke bi-fold. If you need any assistance give us a call or chat to us on our live chat, we are always happy to help!

Not as standard, however this can be added on as an option.

No, they’re not manufactured with a fire rating.

FENSA registered relates to the installer being part of the Fenestration Self-Assessment Scheme, this is in response to building regulations. A FENSA registered fitter means that they self-certify the compliance of the product they are installing with building regulations.

Below are our templated products this allows you to grasp what tolerances we allow for the installation.

The Opening

Normally on bi-folding doors we allow 20mm overall width wise (10mm either side) and 10mm overall height wise (5mm to the top and 5mm to the bottom).

The Track System

Here are the instructions from the track manufacturer: https://centorhardware.com/eu/sites/default/files/product-files/2017-10/instructions_e3.pdf

The tolerances we allow for on our French doors differ from our bi-folding doors. Usually we would allow overall 10mm on the width, 5mm either side, then overall 10mm from the height, again 5mm top and bottom.

Structural Opening Size Manufacture Size
Width (mm) Height (mm) Width (mm) Height (mm)
1410 2110 1400 2100
