Have you got your eye on a stable door? Do you love the style but aren't sure of the benefits?

Look no further. In five minutes, you'll learn everything you need to know about stable doors – including their history, their perks and why uPVC is best.


Let's dive in.


A short history of stable doors

Stable doors (or 'Dutch doors', as they are sometimes known) have a long history of practical use on farmhouses, stables and barns. The style originated in Northern Europe and dates back as far as the 17th century.


The practical design of the stable door, with its central divide, meant agricultural workers could keep livestock safely in (or out of) an area. At the same time, it allowed for access to sunlight and ventilation. 


Over time, the practical benefits of stable doors combined with their unmistakable country charm led to a huge rise in their popularity throughout Europe. 


Nowadays, stable doors can be found anywhere from rural cottages to contemporary townhouses. They've truly won us over with their unique blend of style and practicality.


What makes stable doors different?

Looking for versatility? You've found it.


With both the top and bottom sections of the door secured together, a stable door acts much the same as a conventional door. However, if you lock the lower section of the door, the top half can be opened independently. This creates an effective barrier while allowing for floods of sunlight and fresh air to flow into your home.


This feature makes stable doors an attractive option for all sorts of homeowners:


  • Those with young children or pets
  • Those looking to increase ventilation in their homes
  • Those who enjoy feeling closely connected to outdoor spaces
  • Anyone who wants to add a little character to their home


What are the main benefits of stable doors?

Our top pick: unhindered sunlight and ventilation.

As we've seen, the clever design of the stable door allows the top and bottom sections to be manipulated independently of one another. This means you can keep children and young pets inside while still enjoying plenty of sunlight and fresh air.


The benefits of natural light and ventilation should not be underestimated.


Exposure to sunlight helps the body produce vitamin D and has been linked to an increased endorphins and serotonin. Not only that, but it can also help regulate your circadian rhythm – the bodily ebb and flow that governs our sleeping patterns. 


Improving ventilation, meanwhile,  is one of the best things you can do to prevent damp and mould. The increased airflow reduces condensation and the potential for moisture damage. It also improves air quality, removes odours and can help regulate indoor temperatures on warmer days.


Why choose uPVC stable doors?

Known for its durability and energy efficiency, uPVC has been a game-changer in the world of windows and doors.

See, stable doors were originally crafted from wood. However, while sturdy, this material can warp, rot and eventually become unsightly if not properly maintained.


However, a uPVC stable door from Calder Windows will stand the test of time – no matter what the weather throws at it. 

With unwavering weather resistance, excellent energy efficiency and minimal maintenance requirements, uPVC is a hard option to beat for any new door installation. And they don't skimp on style, either. With many colour, style and glazing options available, our uPVC stable doors are delightfully customisable. 


Is a uPVC stable door the right choice for my home? 

It's easy to be sold on the aesthetic appeal of a uPVC stable door. However, its dual-opening function may or may not suit your home depending on your family's specific needs and preferences.


Let's take a look at some of the most frequently asked questions on uPVC stable doors. We hope this helps you decide whether they're the right choice for you. 


Are uPVC stable doors secure?

uPVC stable doors are great for keeping young children and small pets indoors – and they do a good job at keeping unwelcome visitors out, too.


uPVC is a lightweight but strong material that can withstand even the most determined trespasser. This ensures an effective barrier against any forced entries, keeping your home the safe haven that it should be.


What's more, all uPVC doors from Calder Windows come fitted with top-quality Yale locks. And thanks to the weather-resistant properties and long-lasting nature of the material, your stable door should stay sound for many years to come.


Are uPVC stable doors energy efficient?

Our uPVC stable doors are built to keep warm air in and cool air out (unless you open the top half, of course).

uPVC's low thermal conductivity and tightly sealed frames help prevent heat loss. This means your rooms stay warm and comfortable on cooler days, saving you money on your heating bills and reducing your home's overall energy consumption. 


Do uPVC stable doors require a lot of maintenance? 

Thanks to its natural weather resistance and smooth finish, uPVC is a wonderfully low-maintenance material for your stable doors. 


Unlike wood and metal, uPVC doesn't require staining, painting or sanding – and it isn't susceptible to rot or rust. A simple wipe-down with soapy water is all you need to keep your stable door looking and working as good as new.


How durable are uPVC stable doors?

uPVC is an excellent material choice for your stable doors because it's tough and hard-wearing. Being thoroughly weather resistant, your stable door won't rot, rust, warp or crack – no matter what the climate throws at it.


This means you can expect it to last many years, even when faced with harsh weather conditions and regular use. And, even better, it demands minimal maintenance and minimal fuss. Win-win!
