With a multitude of different doors on the market today, property owners across Kent are wondering whether they should opt for a manufactured or natural material. Based in Gillingham, Sunlight Windows is proud to offer a full service to domestic and commercial clients, installing conservatories, bifold doors, composite doors, composite windows double glazing and conservatory roof replacements.

Whether you prioritise safety, aesthetics, budget or energy efficiency, there are several important factors to consider when investing in an external door.

Trusted in Gillingham for our exceptional customer service and premium installations, Sunlight Windows is the smart choice for clients in Kent. Here are three materials to consider:


An umbrella term for doors made up of a variety of materials, including foam, timber, uPVC and GRP Fibreglass, composite doors are some of the most secure models available.

Hugely durable, composite models are optimised to be as efficient and resilient as possible and are tested to withstand sudden impacts and other stresses.

Thermally efficient, composite doors can be coated with a GRP fibreglass skin for a scratch and scuff-proof finish.

Available in a wide range of colours and textures, including wood grain, they are low maintenance and will keep your home safe for decades to come.

Active across Gillingham, we provide a range of services, including:

  • Conservatory Roof Replacements

  • Thermal Roofs

  • Double Glazed Windows

  • Bifold Door Installations

  • Composite Windows

  • Sunrooms

  • Skylights


A popular option for bifold door installations and conservatories, aluminium is a lightweight metal that offers excellent protection for your home.

A mid-budget option, our aluminium bifold doors and other doors come with double glazing included and are on offer in a wide variety of attractive shades and finishes.

Aluminium doors with double glazed windows do not fade in sunlight, and will hold their colour for years, with the proper maintenance.


Ideal for property owners on a budget, uPVC offers a cost-effective solution for properties of any size or description. Easy to install, uPVC is a solid alternative to timber, and is often more thermally efficient.

Although not the most secure, uPVC provides an acceptable level of protection for homes and businesses across the Gillingham area and is a common sight across the country.
