Metal Patio Doors – Complete Buyer’s Guide

Advantages of Metal Patio Doors

Metal patio doors offer a range of benefits that set them apart from other materials. From their robust construction to their sleek appearance, these doors have become increasingly popular among UK homes.

Strength and Durability

Metal frame patio doors are built to last. Their sturdy construction withstands the test of time, resisting warping, rotting, and corrosion. Unlike wooden doors that may swell or shrink with changing humidity, metal doors maintain their shape and function year-round.

In coastal areas, where salty air can wreak havoc on less durable materials, metal sliding patio doors prove their worth. With proper maintenance, they can outlast many other door types, often lasting 30 years or more. This longevity translates to cost savings over time, as replacements are needed less frequently.

Modern Aesthetics

The clean lines and contemporary look of metal glass doors can make a massive difference to the appearance of a home. Their slim profiles allow for larger glass panels, bringing more natural light into your living spaces. This design feature blurs the boundary between indoor and outdoor areas, creating a sense of spaciousness.

Metal framed doors come in a variety of finishes, from brushed steel to powder-coated colours. This allows them to complement both modern and traditional architectural styles. For example, for a bold statement, black sliding patio doors often work well by creating a striking contrast against light-coloured walls or lush garden backdrops.

Security Benefits

When it comes to home security, metal framed external doors offer peace of mind. Their inherent strength makes them difficult to force open, deterring potential intruders. Many metal patio door systems come with multi-point locking mechanisms, further bolstering their security features.

Materials Used in Metal Patio Doors

Metal patio doors come in various materials, each with unique properties. The choice of metal affects not only the door’s appearance but also its performance and longevity.

Aluminium Patio Doors

Aluminium has become a favoured material for modern metal sliding doors. Its lightweight nature allows for larger glass panels without compromising structural integrity. Aluminium patio doors resist corrosion naturally, making them suitable for coastal homes where salt air can damage other materials.

These doors often feature slim frames, allowing more light to enter your home. Despite their slender profiles, aluminium doors offer excellent strength and stability. They’re available in a wide range of colours and finishes, from anodised silver to powder-coated hues that mimic wood grain. They are also widely available, with many manufacturers offering metal bi fold patio doors, metal double doors, metal slide doors, metal French patio doors, metal slide and stack doors, and more.

Aluminium’s thermal efficiency has improved greatly in recent years. Many aluminium doors now incorporate thermal breaks – insulating barriers within the frame that reduce heat transfer. This advancement has addressed previous concerns about the material’s insulating properties.

Steel Patio Doors

Steel doors exude an industrial chic that’s gained popularity in both contemporary and period homes. Their robust construction provides unmatched strength and security. Metal framed doors made from steel can support larger glass panes than other materials, creating dramatic visual impact.

While heavier than aluminium, steel patio doors offer superior durability. They resist warping and expansion, maintaining their shape in various weather conditions. Steel’s strength allows for even slimmer frames than aluminium.

Contrary to popular belief, modern steel doors can offer good thermal performance. Advanced manufacturing techniques have improved their insulation properties. However, they may require more maintenance than aluminium to prevent rust, especially in humid or coastal environments.

Metal Patio Doors vs uPVC Patio Doors

Lifespan and Upkeep

Metal patio doors typically outlast their uPVC counterparts. While uPVC doors might need replacement after 15-20 years, well-maintained metal sliding doors can last 30 years or more. This longevity often justifies their higher initial cost.

Upkeep requirements differ between these materials too. uPVC doors are low-maintenance, needing only occasional cleaning with soap and water. Metal framed patio doors, particularly those made of steel, may require more attention. Regular checks for scratches or chips in the finish are essential to prevent corrosion, especially in coastal areas.

However, the durability of metal means that even with this extra care, they often prove more cost-effective in the long run. When damage occurs, metal doors can often be repaired, while uPVC doors frequently need full replacement.

Insulation Properties

Thermal performance is a key factor to have in mind when buying any external door. Traditionally, uPVC held an advantage in this area, but advancements in metal door design have levelled the playing field. Modern metal frame sliding patio doors often incorporate thermal breaks – insulating barriers within the frame that reduce heat transfer.

The slim profiles of metal doors allow for larger glass areas, which can be fitted with high-performance double or triple glazing. This combination can result in excellent overall thermal efficiency, matching or even exceeding that of uPVC doors.

It’s worth noting that the thermal performance of metal doors can vary depending on the specific metal used. Aluminium, for instance, conducts heat more readily than steel, but this is often offset by advanced design features.

Price Comparison

Initial costs for metal patio doors are typically higher than uPVC alternatives. The price difference can be substantial, with metal doors sometimes costing twice as much as their uPVC counterparts. However, this higher upfront investment often pays off over time.

The longevity of metal framed patio doors means you’ll likely replace them less frequently than uPVC options. The robust nature of metal doors can also sometimes lead to lower insurance premiums due to improved security. These factors can offset the initial price difference over the lifespan of the doors.

Environmental Factors

Environmental impact is increasingly important for many homeowners, and metal patio doors, particularly those made from aluminium, score well in this area. Aluminium is highly recyclable, with the recycling process using only 5% of the energy required to produce new aluminium.

uPVC, while recyclable in theory, is often not recycled in practice due to the complexities and costs involved. The production of uPVC also involves the use of non-renewable resources and can release harmful chemicals.

Steel doors, while not as easily recyclable as aluminium, are still more environmentally friendly than uPVC. They’re incredibly durable, reducing the need for replacements, and can be recycled at the end of their life.

Heritage Metal Patio Doors

The charm of bygone eras continues to captivate homeowners across the UK. Metal patio doors can play a big part in recreating these classic looks while offering modern performance. From Victorian conservatories to Art Deco-inspired extensions, heritage-style doors can add character and authenticity to period properties.

Crittall Style Doors

Sliding crittall doors have experienced a resurgence in popularity, thanks to their distinctive grid-like appearance. Originally developed in the 19th century, these steel-framed doors feature slim profiles and geometric patterns that create a striking visual impact. Their timeless design complements both traditional and contemporary interiors, making them an option for a wide range of architectural styles.

Modern metal sliding doors in the crittall style offer improved thermal performance and security features while maintaining the iconic aesthetic. Manufacturers now produce these doors using advanced materials and techniques, resulting in better insulation and weather resistance than their historical counterparts.

Art Deco Designs

The Art Deco movement of the 1920s and 30s left an indelible mark on architectural design. Metal frame patio doors inspired by this era often feature bold geometric patterns, symmetrical designs, and decorative glass panels. These doors can turn an ordinary opening into a stunning focal point, adding a touch of glamour and sophistication to your home.

Heritage patio doors in the Art Deco style typically incorporate materials like bronze or brass, which develop a rich patina over time. This aging process adds depth and character to the doors, making each set unique. Some manufacturers offer modern interpretations of these designs using more contemporary materials like powder-coated aluminium, providing the look of heritage doors with improved durability and lower maintenance requirements.

Integrating Heritage Styles

Incorporating heritage-style metal patio doors into modern homes requires a delicate balance. These doors can serve as a bridge between old and new, adding depth and interest to contemporary spaces. For example, a set of crittall style metal bifold doors could create a striking division between a modern kitchen extension and a traditional garden.

When selecting heritage style doors, it’s important to think about the overall architectural context of your property. While authenticity is key for listed buildings or conservation areas, many homeowners opt for a more relaxed approach, mixing period-inspired elements with modern design features. This fusion can result in unique, personalised spaces that respect historical aesthetics while meeting contemporary living needs.

Some manufacturers offer bespoke services, allowing you to customise your metal framed doors to match existing period features in your home. This might involve replicating specific glazing patterns, incorporating period-appropriate hardware, or matching the colour to other architectural elements.

Maintaining Metal Patio Doors

Proper care ensures your metal patio doors remain in top condition for years to come. Regular maintenance not only preserves their appearance but also extends their lifespan and maintains their performance.

Cleaning Methods

Cleaning metal sliding doors is straightforward but requires attention to detail. For routine cleaning, a solution of mild soap and warm water applied with a soft cloth or sponge usually suffices. Avoid abrasive cleaners or rough materials that could scratch the surface. After washing, rinse thoroughly with clean water and dry with a lint-free cloth to prevent water spots.

For aluminium doors, specialised aluminium cleaners can remove stubborn stains without damaging the finish. Steel doors might benefit from a light application of mineral oil after cleaning to prevent rust. Always check the manufacturer’s guidelines before using any cleaning products on your metal frame patio doors.

Glass panels require regular cleaning too. A mixture of white vinegar and water, applied with a microfibre cloth, can leave your glass streak-free. For tough marks, a small amount of baking soda mixed into a paste can work wonders, but be careful not to let it touch the metal frames.

Rust Prevention

Preventing rust is key to maintaining metal framed doors, especially in coastal areas where salt air can accelerate corrosion. Inspect your doors regularly for any signs of rust or damage to the protective coating. Small chips or scratches in the finish should be touched up promptly to prevent moisture from reaching the metal underneath.

For steel patio doors, applying a thin layer of car wax every few months can provide an extra barrier against moisture. In particularly humid environments, using a dehumidifier near your metal glass doors can help reduce moisture levels and prevent rust formation.

Ensure that drainage holes in the door tracks are clear of debris to prevent water buildup. Standing water can lead to corrosion over time, compromising the door’s operation and appearance.

Improving Thermal Performance

While metal patio doors are designed for good thermal performance, a few maintenance steps can help optimise their efficiency. Check the weatherstripping around the doors annually and replace it if it shows signs of wear or damage. Properly sealed doors prevent drafts and improve overall insulation.

For older metal sliding doors, retrofitting with modern double or triple glazing can massively improve their thermal properties. Some companies specialise in upgrading heritage metal doors with new glass units that maintain the original aesthetics while boosting energy efficiency.

Regularly lubricating the moving parts of your metal framed external doors not only ensures smooth operation but also maintains the integrity of the seals, contributing to better thermal performance. Use a silicone-based lubricant on rollers, tracks, and locks as recommended by the manufacturer.

Expected Lifespan

With proper care, metal patio doors can last for decades. Aluminium doors typically have a lifespan of 30-40 years, while steel doors can last even longer. Bronze doors, though less common, can last for generations with appropriate maintenance.

The longevity of your doors depends on various factors, including local climate, usage patterns, and maintenance routines. In coastal areas, more frequent maintenance may be necessary due to the corrosive effects of salt air. Regular inspections can help identify and address potential issues before they become serious problems, extending the life of your doors.

Keep in mind that while the metal frames may last for many years, other components like seals, rollers, and locks may need replacement sooner. Staying on top of these smaller repairs and replacements can prevent more troublesome issues and help your metal patio doors reach their full lifespan potential.
