Choosing the right internal doors can make a real difference to how your home looks and feels. From classic panelled designs to contemporary steel-look doors, the right style can complement your interiors, let natural light flow between rooms and help you make better use of your space.
At Advanced Glazing Systems, we’ve spent 22 years helping homeowners across Essex, London and the surrounding areas find the right glazing and door solutions for their homes. While much of our work focuses on external glazing, we also offer a range of internal doors, including our Heritage Decorio collection. Here’s what to consider when choosing internal door suppliers in Essex.
Choosing the right internal door style
Interior doors play a key role in the overall design of a room. Whether you’re updating your living room or modernising your bedrooms, consider your existing decor and the personality of your home when choosing a style.
Popular options include:
- Flush doors – a great option for minimalist designs and modern decor.
- Panelled and oak doors – traditional designs and oak finishes can complement period properties and their original character.
- Glass panel doors – an internal glazed door allows natural light to travel between rooms, creating a sense of spaciousness.
- Steel-look doors – slim frames and large glass panels offer a more contemporary feel.
You should also consider colour and finish. White internal doors offer a versatile option for many interiors, while darker finishes can create contrast in modern homes. Choose a look that complements your existing decor.
Materials, frames and sizes
A door’s material affects its appearance, weight and maintenance requirements. Solid doors can help reduce sound travelling between rooms, depending on their construction and how well they’re fitted, making them worth considering for bedrooms. Glazed internal aluminium doors are a great option for keeping spaces bright and open.
Measure before you buy
Door frames vary between properties, particularly in older homes. Before replacing an old door, check:
- Width: Measure at the top, middle and bottom of the opening, and record each measurement.
- Height: Check the height of the door frame on both sides.
- Thickness: Measure the thickness of the frame and check the requirements for the replacement.
The most common sizes suit many homes, but narrower doorways and uneven openings may need a made-to-measure option. Ask your supplier to confirm the measurements before ordering. Handles, hinges and other door hardware are also a key element of the finished look.
Where our Heritage Decorio range fits in
Our Decorio range recreates the classic steel look using modern aluminium frames and large glass panels. With hinged and sliding doors, as well as fixed screens, it offers a stylish way to divide rooms while allowing natural light to flow between spaces.
For example, a glazed divider between a kitchen and dining room can help define each area while keeping the layout feeling open.
Aluminium is strong, lightweight and low-maintenance. With a choice of finishes and hardware, these doors offer a practical way to introduce steel-inspired styling into your home.
Loft conversions and extensions
These projects often involve rethinking how rooms connect, so consider practical requirements alongside appearance.
Loft conversions
Fire safety needs careful consideration when converting a loft. Depending on the property’s layout and proposed escape route, fire doors may be required to help protect the staircase.
Bath & North East Somerset Council’s guidance for certain loft conversions specifies FD20 fire doors for existing doors to habitable rooms opening onto the hall or landing. Requirements depend on the property and project, so consult your building control officer before choosing doors. The complete doorset, including its frame and ironmongery, must meet the required specification.
Extensions
An extension is an opportunity to create a smooth transition between existing rooms and your new living space. Glazed internal doors can separate a kitchen, dining area or home office while allowing light to pass through.
If you’re creating a modern office space, a glazed divider can provide a more professional appearance without making the room feel closed off. Consider how you’ll use the space before deciding on the best layout.
Accreditations and service to check
A quality product is only part of the decision. When comparing suppliers, look for:
- Recognised accreditations: Check relevant memberships and schemes, including the GGF and TrustMark.
- Clear guarantees: Understand what’s covered and whether insurance-backed protection applies.
- Independent reviews: Read feedback on platforms such as Checkatrade and Google.
- Helpful advice: Look for a supplier offering clear guidance, whether in a showroom, over the phone or through an online chat feature.
At Advanced Glazing Systems, we’re backed by the GGF and hold accreditations including FENSA and TrustMark. Our Decorio installations come with a 10-year guarantee on parts and labour, alongside insurance-backed protection through GGFi, subject to the applicable terms.
We’re proud of our customer feedback. Checkatrade currently displays a rating of 9.9/10 from 708 reviews. We work hard to provide first-class service from your initial enquiry through to project completion.
