Bifold doors are best installed in a large opening on one side of your home, ideally leading out onto a garden or patio space.
Whilst you can choose to have bifold doors fitted in place of traditional french doors, they’re better suited to larger openings, so that you can make the most of the increased light and air coming in.
The Liniar Alumina bifold door system facilitates from 1 pane to as many as 7 opening sashes up to 6m wide. This allows them to easily fit into most home renovation projects.
You have a number of options open to you when choosing your bifold doors including:
> Number of doors. Depending on the space you have, you can choose between 1 and 7 bifold doors for your installation.
> Configuration of doors. There are a number of setups you can choose from depending on the number of doors you choose. This will determine how the doors open and fold onto each other.
> External styling. Choose between sculptured and chamfered decorative aesthetic styles.
> Colour finishes. 11 colour finishes are available, including white, black and grey to wooden finishes.

The key difference between a composite door and a uPVC door lies in their materials and construction. Whereas uPVC doors are made entirely of plastic, composite doors are composed of a number of different materials with the intention of making them stronger and hard-wearing.
For example, the Rockdoor composite doors that we fit are composed of GRP (glass reinforced plastic) in addition to rigid uPVC profiles and reinforced aluminium frame boxes. This combines to create a door that is incredibly secure and thermally efficient.
All doors, regardless of the materials, will expand to a greater or lesser degree during the heat of the summer. The issue is really how much this happens, and how this impacts the door fitting.
We chose Rockdoor as our composite door supplier, as they have put extensive research into their products. They offer a ‘no-bow guarantee’ on all their doors, so you can buy with confidence knowing that your door will remain properly in place, no matter how hot it gets.
Composite doors are more expensive than most uPVC and wooden doors, which naturally raises the question of if they’re actually worth the investment. The best composite doors offer class-leading high security, thermal performance and durability that other types of doors simply can’t compete with.
Composite doors have a typical lifespan of at least 30 years. Depending on the weather conditions and how well you look after it, yours could well last longer on this.
The Rockdoor composite doors we fit are made with the following:
First a high impact skin is formed onto an aluminium mould.
The inner frame is made using rigid uPVC profiles with an aluminium reinforced box section.
S-Glaze glass is used to fit any windows that you require, providing excellent security.
The door is then injected with Polyurethane Foam to ensure that any gaps are filled.
The door is cut down to size using CNC technology before multipoint hook looks are fitted for maximum security.
One of the best features of a composite door is that they don’t require much maintenance when compared to their wooden counterparts. One of the ways that you can extend the life of your door is by giving it a gentle clean once a month. This can be as simple as wiping it down with warm, soapy water and a soft cloth.
All of our French doors are made from uPVC. UPVC is a robust, rigid material. The secure frames and unique locking system provide the necessary strength to make it tough for anyone to break in. Triple-glaze your uPVC French doors, for added protection and thermal resistance.
French doors offer many advantages, but can sometimes become misaligned, however, this can be avoided by ensuring your french doors are properly sized, fitted and used properly.
They can also become obstructed by objects and dirt along the tracking. Be careful to clean these areas on a regular basis to avoid damage to the frame.
In short, yes you can. However, we suggest not to, since uPVC is not designed to be painted and therefore needs extra care such as specific paint requirements.
Taking care of your new doors, keeping them cleaned and dusted as required and following our aftercare advice can mean your new French doors will last around 30 years.
