The Benefits of Upgrading to a Composite Door
Your front door plays an important role in your home’s security, energy efficiency and appearance. If your entrance door shows signs of wear, upgrading to a composite door could make a noticeable difference to everyday comfort and peace of mind.
At Square Glaze, we supply and install high-quality Solidor composite doors across Aylesbury and Buckinghamshire. Combining robust construction with modern security features and attractive designs. Here are the main benefits of upgrading to a composite door and what to consider before choosing your new entrance.
What Is a Composite Door?
A composite door is an external entrance door made using several materials to combine strength, insulation and durability. Unlike traditional timber or uPVC doors, composite doors use a layered construction designed to provide reliable performance with minimal maintenance.
Our Solidor composite doors feature a substantial 48mm solid timber core, durable outer materials, and weather-resistant seals. The result is a strong, secure entrance door that can be customised to complement your property.

1. Improved Home Security
One of the biggest benefits of upgrading to a composite door is the enhanced security. Modern composite doors combine strong construction with advanced locking systems to help protect your home against forced entry.
Our Solidor composite doors feature robust timber-core construction and can incorporate high-security Ultion locking cylinders and multi-point locking systems. These security features help provide additional protection compared with an ageing door with damaged hardware or outdated locks. You can explore the available options through Solidor’s door security guidance.
2. Better Thermal Efficiency and Comfort
Energy-efficient composite doors help reduce heat loss and keep your home comfortable year-round. Solidor composite doors feature insulated construction and weather-resistant seals designed to minimise draughts and prevent cold air from entering around the door. Modern energy-efficient external doors can help reduce heat loss and improve household comfort; see the Energy Saving Trust to find out more.
If your existing entrance feels cold or draughty, upgrading to a properly fitted composite door may help reduce unnecessary heat loss. Actual energy savings will depend on your existing door and your property’s overall insulation.
3. Long-Lasting Strength and Durability
Composite doors are designed to withstand everyday use and changing weather conditions. The robust construction of our Solidor doors provides excellent resistance to common problems associated with ageing timber doors, including warping, swelling and deterioration.
Durable outer finishes also help protect your entrance’s appearance from everyday exposure to rain, wind, and sunlight. With suitable care and maintenance, a high-quality composite door can remain an attractive and dependable feature of your property for many years.
4. Less Maintenance Than Traditional Timber Doors
Another advantage of composite doors is their low-maintenance design. Traditional timber doors may require regular painting, varnishing or treatment to protect the surface. Composite doors have durable external finishes that generally require much less upkeep.
Occasional cleaning with mild soapy water, along with routine checks of hinges, seals, and locks, can help maintain appearance and performance. This makes composite front doors particularly appealing to busy homeowners looking for a practical, long-lasting entrance.
5. More Colours, Styles and Customisation
Upgrading to a composite door lets you transform your home’s entrance without compromising its character. At Square Glaze, our Solidor composite doors come in traditional and contemporary styles, with a range of colours, decorative glazing designs, and hardware options.
Whether you prefer a classic woodgrain finish for a period property or a bold colour for a modern home, our doors can be tailored around your preferences. The extensive range of Solidor door colours and finishes makes it easier to create an entrance that complements your windows, brickwork and exterior design.
6. Improved Noise Reduction
A well-insulated composite door can also help reduce unwanted outside noise. The solid construction and effective weather seals of our Solidor doors help limit sound transmission through the entrance.
This can be particularly useful for properties near busy roads or pedestrian areas where external noise affects indoor comfort. The level of noise reduction depends on the complete doorset, including any glazing, seals, and installation details.

Are Composite Doors Better Than uPVC Doors?
Composite and uPVC doors both offer reliable security, insulation and low-maintenance performance. However, they differ in key ways.
Composite doors are particularly appealing if you want solid-core construction, traditional timber-inspired styling and extensive customisation options. uPVC doors are often a more budget-friendly choice while still offering practical everyday performance. Neither material is automatically the best option for every property. Your budget, design preferences and security requirements should guide the decision.
