BI-FOLDING DOORS

External bifold doors are innovative door systems that can fold in or out to open up space, typically used to connect indoor environments with outdoor spaces such as patios, gardens, or balconies. These doors consist of multiple panels that are connected through hinges. When opened, the panels fold against each other, resembling an accordion. Bifold doors have become popular due to their ability to provide expansive, unobstructed views while also being incredibly space-efficient. The use of large glass panels allows natural light to flood the interiors, creating a seamless integration of indoor and outdoor spaces.

Bifold doors can be used in various locations within residential or commercial properties. In residential settings, they are commonly used to connect living rooms or kitchens with gardens, patios, or balconies, thereby extending the living space. They are also used in bedrooms that have access to private outdoor areas. In commercial settings, bifold doors are ideal for restaurants, cafes, and retail stores looking to create an open environment that seamlessly transitions into outdoor seating or display areas. Additionally, they can be used internally to divide larger spaces such as conference rooms or banquet halls into smaller, more intimate areas when needed.

In most cases, installing exterior bifold doors in your property doesn’t require planning permission as it is often considered to be permitted development. However, there are exceptions. If your property is listed or located in a conservation area, you may need to obtain permission. Additionally, if the installation is part of a larger renovation project that significantly alters the building’s structure or appearance, planning permission may be required. It’s always best to check with your local planning authority to ensure that you are complying with all relevant regulations before proceeding with the installation.

The cost of bifold doors varies depending on several factors including the size, material, glazing options, and custom features. Generally, aluminium bifold doors are more expensive than uPVC doors but are more durable and considered more aesthetically pleasing. Timber bifold doors can be even more expensive due to the material and craftsmanship involved. On average, you can expect to pay anywhere from €2,000 to over €10,000 for bifold doors. It’s important to consider not only the initial cost but also the long-term value, as higher-quality doors may offer better energy efficiency and durability.

Ready-to-assemble (RTA) refers to products that are sold in pieces and require assembly by the consumer. These products are typically packed flat with all the necessary parts included, along with instructions for assembly. This is a common practice in the furniture industry and is also used for products like cabinets and even some types of doors. RTA products are generally more affordable and easier to transport than their pre-assembled counterparts. However, assembly can be time-consuming and sometimes requires a certain level of skill or tools.

Top-hung bifold doors have their weight supported by rollers at the top while bottom-rolling bifold doors have their weight supported by a track on the floor. Top-hung systems usually provide a smoother operation and do not collect dirt and debris because they don’t have a bottom track. This makes them ideal for indoor-outdoor transitions. However, they require a strong and sturdy upper structure to support the weight of the doors. On the other hand, bottom-rolling systems can be easier to install as they don’t require structural reinforcement above the doors, but they require regular maintenance of the bottom track. The choice between top-hung and bottom-rolling will depend on your specific requirements and the structure where the doors will be installed.

The energy efficiency of external bifold doors depends on the materials, glazing, and installation quality. Modern bifold doors are often highly energy-efficient. They often come with double or triple glazing, which minimises heat transfer, and thermal breaks in the frame, which prevent cold transmission through the metal. High-quality seals and gaskets ensure that the doors are airtight, preventing drafts. When choosing bifold doors, look for a low U-value (which measures how effective a material is as an insulator) to ensure high energy efficiency.

The decision to have bifold doors open inwards or outwards depends on the available space and the intended use. Inward-opening doors can be beneficial to maintain the clean lines of the exterior façade and are less likely to be affected by wind. However, they do take up interior space when open. Outward-opening doors are ideal if interior space is limited, but they may be affected by wind and weather conditions. Consider the layout of furniture and the intended flow of traffic when deciding on the opening direction.

Trickle vents are small openings built into windows or doors that allow for a controlled flow of ventilation. They help in preventing condensation and ensuring there’s a continuous exchange of air, which is beneficial for indoor air quality. In certain jurisdictions, building regulations require the installation of trickle vents for new doors and windows to ensure adequate ventilation, especially in more airtight modern homes. If you’re replacing old doors that already have trickle vents, you are generally required to include them in the new installation.

Modern external bifold doors are designed with security in mind. High-quality bifold doors often come with multipoint locking systems, toughened or laminated glass, and sturdy frames which provide excellent security. Moreover, internally beaded frames prevent the glass from being removed from the outside. When looking for bifold doors, ensure that they meet relevant security standards. Some bifold doors are also compatible with smart security systems for additional peace of mind.

Composite bifold doors are made from a combination of materials to maximise the benefits of each. Most commonly, they combine a wooden frame with aluminium or uPVC cladding. The wooden frame provides excellent insulation and a traditional aesthetic, while the aluminium or uPVC cladding is low maintenance and durable. Composite doors aim to provide the beauty of natural wood while reducing the maintenance required and increasing the door’s lifespan. They can be an excellent choice for those looking for both performance and aesthetic appeal.
