Choosing new windows or doors can be overwhelming – especially when websites are full of technical terms that aren’t clearly explained.
If you’ve ever browsed a window or door supplier’s website and left more confused than when you arrived, this guide is here to help. We’re breaking down some of the most common – and confusing – terms, so you can make informed decisions about what’s going into your home.
No fluff, no sales pitch – just clear explanations of the terms you’re most likely to come across.
Aluminium Doors
Aluminium doors are a sleek, modern option that offer strong durability with a clean, contemporary look. Aluminium is a lightweight, non-magnetic metal that suits almost any colour palette, making it a popular choice for both new builds and renovations.
Why choose aluminium?
- Aesthetic appeal – slim sightlines and modern finish
- Durability – naturally weather-resistant and low maintenance
- Sustainability – recyclable and long-lasting
However, aluminium conducts heat, which can affect thermal performance. That’s why high-quality aluminum doors often include a polyamide thermal break – a barrier within the frame that improves insulation. This feature is essential for homes in cooler climates, helping to keep energy bills in check.
Prefer a warmer or more traditional look? Timber frames offer a natural alternative, though they typically require more maintenance.
Solidor Composite Doors
Solidor composite doors might sound complicated, but they’re actually one of the most practical front door choices on the market. “Composite” simply means the door is made from a combination of materials – in this case, a solid hardwood core wrapped in a robust ABS plastic skin (the same type of plastic used in car bumpers).
Key benefits:
- Exceptional strength and security
- Weather resistance – no warping or flaking
- Wide range of colours and finishes
These doors are ideal for front entrances and side access points, offering excellent protection from the elements and versatile design options to suit existing or new homes. Their tough exterior makes them one of the most durable options available – combining traditional strength with modern performance.
Think of Solidor composite doors as high-spec hybrids: stylish, secure, and built to last.
Profile 22 Doors
Profile 22 doors refer to a premium system of uPVC door and window products made by a leading UK manufacturer. The “Optima” line, which you’ll see featured on our site, is one of their most popular ranges.
These doors are known for their multi-point locking systems, making them a go-to choice for homeowners prioritising safety and thermal efficiency.
Why choose Profile 22?
- Enhanced security – multi-point locks for added protection
- Excellent insulation – built from thermally efficient uPVC
- Longevity – expected lifespan of 30+ years
Unlike composite doors (which have a timber core), Profile 22 doors are made from uPVC throughout, offering similar benefits with more options for personalisation, glazing, and hardware.
Perfect for families or landlords looking for long-term reliability with minimal upkeep.
