The benefits of bringing more natural light and space into the home are becoming increasingly clear.
Studies have proven that having a naturally well-lit home can improve mood and productivity, provide better sleep quality, reduce stress, and increase vitamin D production. This is on top of the financial perks, including reduced energy bills.
It’s no surprise therefore, that we’ve noticed a huge spike in demand for French doors across Plymouth, with the romanticised style celebrated for a whole host of benefits, on top of light intake and added space.
We’ll explore French doors in depth in this blog, taking a look at what makes them unique, as well as the options available to homeowners in the local area.
What Are French Doors?
French doors are a stylish pair of external doors that open either inwards or outwards from the centre, creating a wide access point between your home and garden.
Traditionally crafted from timber, modern uPVC French doors provide excellent durability, energy efficiency, and low maintenance — ideal for homes in Plymouth and the surrounding South West.
Contrary to popular belief, French doors originated in Renaissance Italy, and have been a highly-desirable home improvement product ever since.
They were soon adopted by French castles and stately homes, becoming a symbol of wealth, before the design experienced widespread demand across Europe, including the UK mainland, for reasons we’ll explain below.
What are the Benefits of French Doors?
Maximise Natural Light
French doors flood your home with natural light, brightening living areas and making rooms feel larger and more inviting. The slim sightlines of our doors ensure you enjoy expansive views without bulky frames obstructing your garden.
Create a Seamless Indoor-Outdoor Flow
French doors make transitioning between your indoor living space and outdoor areas effortless. Whether you’re hosting a summer BBQ or simply relaxing, these doors open your home up, bringing the outside in. You can open them to enjoy a fresh breeze whilst sat inside, or eliminate the dividers between in and out.
Energy Efficiency
Our multi-chambered Profile 22 uPVC frames offer excellent insulation, reducing heat loss and helping keep your home warm year-round — a practical consideration for the South West’s sometimes chilly coastal climate.
Safety Glass and Security
We fit safety glass as standard, giving you extra protection and peace of mind. Plus, with options like the Yale locking system and PAS 24 accredited locking door configurations, you can rest assured your home is secure.
Increased Home Value
If you’re put off by the initial investment, it’s worth bearing in mind that the high desirability of French doors means that the outlay will be reflected by a rise in your home’s value.
