French doors, a timeless classic, create continuity between the interior and the exterior of our homes.

But did you know that they hold a magical power?

There is something about them, a 'je ne sais quoi', that seems to make a wonderful connection between the inside and our outside space.

The light that floods in seems to add character and romance to even our most ordinary room.

And once we have french doors in our home, they immediately make even a modest garden seem inviting.

The slightest temperature rise or glimpse of sunshine and it's as though we are compelled to open our french doors.

Of course this is no bad thing but before we get carried away let's tackle a few practical questions that come up when we are buying french doors.

What style is right for my home?

All homes have an architectural style, choosing windows and doors that are sympathetic to our design is the first step to us making the right choice.

Whether we have a modern, contemporary home or a traditional cottage with mullions it is usual to try to adhere to our home’s character, however, let’s not rule out the dramatic effect that a complete contrast could play.

Let's also think about how our french doors will be used daily and not only during the summer time.

Here's just a few examples of styles that complement their homes character:

What material should I choose?

The team of expert installers at Marlin Windows are often asked about the benefits of aluminium windows and doors over other alternatives such as PVCu and wood. So, here is an honest appraisal of what they say about the different materials:

Natural charm and warmth are qualities that attract people to timber. Although it is the most expensive of the three materials, timber windows and doors do have an authentic nostalgic look.

As a more economical option, PVCu is often the first choice for homeowners looking for replacement windows and doors. PVCu provides excellent thermal performance. One downside is that the profile can discolour over time.

An incredibly resilient and strong material, powder coated aluminium is one of the most durable finishes available. It won’t discolour, rust or peel, giving it a long-lasting, attractive appearance which can last for decades.

Aluminium frames can be slimmer than both wood and PVCu, they have more space for glass so let more light into the home.

Will I be warm in winter?

Look for glazing with a U value of 1.8W/m²K or lower. For more energy savings consider triple glazing.

What upkeep do they need?

Timber does require regular painting to keep the wood sound.

If you’re looking for a design that requires very little maintenance, aluminium is the perfect option as it requires virtually no upkeep.
