Why Are Sliding Patio Doors a Thermally Efficient Option?


Sliding patio doors are a popular installation among homeowners because they blend in indoor and outdoor spaces. Apart from this, they offer numerous energy-efficient benefits. At Dempsey Dyer, we are proud to offer a trade supply for sliding doors,  so in this article, we will explore why these doors are a thermally efficient option for end users. To learn more, read on.

Thermal Design

One of the primary reasons for the thermal efficiency of sliding patio doors lies in their design. These doors typically consist of multiple glass panes, creating an insulating barrier between the interior and exterior of your home. The space between the glass panes is often filled with argon gas, further enhancing the doors’ insulation properties. This design effectively prevents heat transfer, ensuring warmth in winter and coolness in summer.

Weatherstripping and Seals

In addition to their design, sliding patio doors feature weatherstripping and seals that could help reduce air leakage. This is crucial for maintaining a comfortable indoor temperature and reducing energy waste. By preventing drafts and air infiltration, sliding patio doors significantly improve the overall energy efficiency for end users.

Natural Light

Inform your customers that sliding doors provide plenty of natural light in their homes. Not only will this create a brighter space, but it will create a seamless blend between their home and garden. As a result, the sliding doors that you offer will deliver exceptional year-round performance.

High-Performance Glass

When selecting sliding patio doors, it is essential to consider the quality of the materials used. Inform your customers that sliding patio doors offer low e glass, which boosts their thermal efficiency. Low-E glass has a special coating that keeps heat inside during winter and blocks heat from entering during summer. This helps maintain a comfortable indoor temperature year-round and reduces the strain on your heating and cooling systems.

Energy Savings and Sustainability

Investing in thermally efficient sliding patio doors can lead to long-term energy savings for homeowners. By reducing heat loss and gain, these doors help lower heating and cooling costs. Additionally, they contribute to a more sustainable and environmentally friendly home by reducing your carbon footprint.

At Dempsey Dyer, we offer a wide range of high-quality sliding patio doors designed with energy efficiency in mind. Our doors are crafted using premium materials and advanced insulation technologies to ensure optimal thermal performance. Whether you’re looking for traditional or contemporary styles, we have options to suit every homeowner’s taste and budget.

Why Choose Timber Front Doors

Why choose timber front doors? It seems like these days everybody is looking for the latest and most modern entrance doors. However, there are more than a few reasons to remember wooden front doors as an excellent option. Since some older timber doors have issues dealing with the weather and can wear down after only a few years, these designs are outdated.

Today, you could invest in timber front doors that open the door to a warmer and more stylish home. At Dempsey Dyer, we design and manufacture modern timber front doors with a difference. Our options are more resistant to the elements, highly secure, and could even save money on energy bills. Additionally, the designs are fully customisable.

When you work with us, you can get high-performance doors that make a lasting impact. As a homeowner, you can invest in a bespoke entrance, meaning your new door can reflect your home’s unique style. And, if you run a business, you can work with Dempsey Dyer as commercial partners, offering our full range of stunning doors to your clients.

We combine quick service and short lead times with careful design processes and thorough testing. We test our locking mechanisms, for example, over 40,000 times before each door leaves the factory. That way, whether you’re a homeowner or business owner, you can get timber front doors that could change what you think about wood.

Energy Efficient Timber Front Doors

The problem with lesser timber front doors is they crack. Not only that, but you could get thin timber which would allow cold air to pass through into homes. However, Dempsey Dyer’s designs leave no room for the cold to play havoc with a home’s temperature.

Instead, you can get a 58mm thick sash, giving you a door with stunning impact and quality insulation. These timber doors create a thermal barrier for your home, and the sash also helps them when they have to deal with wind and rain. As a result, the doors don’t crack as easily either, meaning no gaps emerge for cold air to gain a foothold.

Because of this, you won’t have to worry about underperforming timber front doors. Instead, they’ll be able to keep their insulation for years to come. These doors, then, could cut the cost of energy bills, and can even decrease a home’s carbon footprint. That makes them a sound investment for both homes and businesses alike.

Secure Timber Front Doors

That 58mm sash does more than keep cold air away. It also helps our timber front doors to be some of the most secure designs on the market. That way, our doors can protect homes reliably, with sturdy timber frames and a range of innovative security hardware.

For a start, our doors meet Secured by Design standards, meaning that you’ll get a door that goes above and beyond to keep you safe. Also, you can get MACO locks for the door that come with a security guarantee. Because of this, you can choose these doors for your home or business with total peace of mind.

The locking mechanisms meet PAS24 requirements, and they’re highly robust. An intruder will have a nightmare with these doors, as they won’t be able to pick or tamper with any locks.

Additionally, you’ll get 24mm double glazing panels in the door with multi-point locking, ensuring that the door channels light from the outside into your home, without letting anything else in.

Weather Resistant Timber Front Doors

One drawback of older timber front doors is how they deal with poor weather. When wind and rain strike these old designs, the wood cracks and warps quickly, leaving homes out in the cold. However, at Dempsey Dyer, we’ve gone a long way to making our timber front doors ready for the worst of the British weather.

For a start, we’ve treated our wood with an extra finishing process, meaning they have even more durability than normal. Additionally, we use high-performance timber species in our designs. For example, our Accoya wood option meets ‘Class 1’ standards for durability, meaning it’s hard to find any wood performing better for longer.

Also, you’ll be able to get layers of protection for your door that won’t get in the way of their design. You can choose translucent and opaque protective finishes, meaning any water has further to travel to damage the wood underneath. That way, your home can stay comfortable all year round, while your business can offer doors that are ready for anything.

We’re all about choice at Dempsey Dyer. That’s choice to style your home how you’d like, and choices for your customers to create them. Because we design and manufacture our timber front doors in-house, we can make them into bespoke options with short lead times for your home or business.

There is a wide range of elements to modify for the door, including handles, sashes and even the wood. You can choose between sleek chrome, gold or silver handles, a selection of four sashes with differing degrees of thickness, and timber species including Accoya, Sapele and European Oak.

Because of this, you can get a bespoke door for your home or business with ease. At Dempsey Dyer, we know how unique every home is. That’s why, whether you own a home or own a business, we’ll give you complete control of what you order.
