FAQ'S About french doors
What are French doors?
French doors are doors with glass that connect a house to a terrace, balcony or garden.
French doors have two important functions:
They assume the classic purpose of a door; and they are also a piece of furniture due to their unique design aesthetic.
What are the materials of French doors?
In addition to the classic wooden frame, the French doors we produce can also be made of a variety of materials such as iron, aluminum, aluminum-clad wood, uPVC, etc.
Features of French doors made of different materials
Wooden French Doors:
These models offer high thermal and acoustic insulation, an elegant appearance, durability, and sturdiness. However, wood requires frequent maintenance and is more expensive.
Aluminum French Doors:
Advantages include modern design, light weight, competitive pricing, multiple customization options, and low maintenance. However, they are not as durable as wood and have lower insulation properties.
uPVC Patio Doors:
uPVC is easy to clean, economical, lightweight, highly durable, and offers the most affordable price-performance ratio. In addition, it prevents condensation.
Types of French door openings
There are many types of French door openings. Here are the most common:
Flat French doors, a very common traditional style.
Folding French doors, often used to create fully open entryways.
Tilt-and-turn French doors, which allow ventilation even on rainy or windy days.
Sliding French doors, which enable large glass panels to slide smoothly. The transom window above allows air circulation while keeping out water.
Pivot French doors, known for their elegance and dignified appearance.
How much does it cost to buy a French door?
Generally speaking, French doors are more expensive than ordinary windows because they require additional glass and framing. Costs may also vary depending on custom trim, ornate handles, or other materials you choose.
Purchase directly from the manufacturer to avoid paying exorbitant fees to middlemen. By doing so, you can save up to 40% by eliminating middleman costs.
The typical cost of bi-fold aluminum doors is approximately $400.
Are French doors from Grandsea safe?
At Grandsea, we recognize that your home should be a secure haven for your family. We strengthen our French doors by installing anti-theft bars, security grilles, and internal screws, in addition to using thick glass. We also offer additional protection features. The term “family security” has many meanings, so we provide surveillance cameras, anti-theft locks, and video intercoms to enhance safety. You can be confident that your family is well protected with all these precautions.
