UPVC French doors – a buyers guide

uPVC French Doors: A buyer’s guide

French doors can add an elegant and classic look to any home, offering an easy flow through the home and linking outside spaces to the home effortlessly. French doors have been popular in British homes for a long time and the classic look will never go out of fashion. There are three options for homeowners in the modern market; French doors, Sliding Doors and Bi-folding doors. French doors are perfect for a medium opening, with two doors which open from the center to give the feel of a large, unobstructed gap. This gives a much wider area than a single door and provides easy access with no central bar or pane of glass, such as you would find on a sliding door. Sliding doors have become less fashionable in recent years and have been criticised for people walking into them and knocking them off their runner! Bi-folding doors are excellent for a large opening but are often excessive for a medium space as they are costly for a limited space.

French Door Materials

There are significant differences in the 3 types of material used for French door manufacture each one has its own features.

Timber: The main issue with using wooden external French doors is that, if not properly sealed, timber will saturate or dry out. This “instability” is what causes timber French doors to deform. They can develop draughts from gaps surrounding the door when the wood shrinks as it dries out or sticks & jams when the wood swells as it absorbs water. However, with good maintenance, hardwood timber doors will last 40 or more years, much longer than other materials.

Aluminum: Aluminium French doors are a good option, being very light and strong. However, also
being made from metal, they are cold to the touch.
The metallic structure of the frame necessitates a thermal break between the inside and outside
surfaces. If this thermal break is not made well, then the frames will transmit heat, cold and even
develop condensation on the inner surfaces.

UPVC French doors: This material has such a lot of things going for it. Light, strong, cost-efficient and a natural
insulator, UPVC frames used for French doors offer the best features of all the other material
combined. Most uPVC doors will last 20 or more years, giving excellent value for money and with a
wide choice of colors on the market now, they are the most versatile. Most uPVC doors also come
with multipoint locking systems as standard, improving the security of your doors.
In addition, uPVC doors are very easy to look after. All that they need to keep them looking as good
as new is a wipe/wash clean. They will never need painting and should retain their colour. They are
not affected by bad weather such as rain, frost, and snow nor should the colour fade in strong
sunlight. The door will not warp due to a change in the air temperature and moisture as a wooden
door does.

Energy Efficiency and Insulation

upvc french doors The door should be well insulated to stop the cold getting in and the heat getting out of your home thus making them very energy efficient. If you have glazing in the door it should either be double or triple glazed. Another benefit of being well insulated is that they should reduce noise levels inside your home if you happen to live on a street that is busy with traffic passing by. A good indication that your door has a quality seal is that when you close it shut it should do so with a good solid feel.
To make the doors as energy efficient as possible, a standard UPVC French door is fitted with double glazed sealed units. To further enhance the performance, the sealed units can be filled with Argon gas and low-emissivity glass can be substituted for standard glass. Some companies are offering triple glazed windows as well but always look for the A+ rated windows as they will be the most energy-efficient available. The UPVC frames themselves are multi-chambered (much like a honeycomb), which also benefits the overall energy efficiency of the door set.

Security

As mentioned previously, uPVC doors are often the most secure set of patio doors on the market. The security of French doors has, in the past, been subject to question. Modern French door designs have addressed previous criticism and can now incorporate security features such as:

1. Multi-point locks that engage at the top, bottom and sides
of the frame.
2. Deadbolts that secure the doors to the top & bottom of the
outer frame.
3. 5 lever mortice key locks on each door leaf.
4. Pinless hinges. 3 sets per door.
5. Internally operated thumb-turn locks (cannot be operated
from the outside).
6. Internally glazed & beaded so the glass cannot be removed
from the outside.
7. Toughened, tempered safety glass.

All these features mean that uPVC French doors are much more secure than their rivals and you can be secure in the knowledge that your doors are just as resilient as your hardwood front door! To make sure you are fully secure, buy a uPVC door with a British Standard PAS 24-1. This means that the door and frame, as well as the locking mechanism, have successfully gone through several physical tests.
