Frequently Asked Questions

23 DOORS are experienced aluminium door manufacturers for the trade and can help you get the ideal front door for your home. Here, we answer some of the most common questions about aluminium doors.

What are the benefits of Alunet BF73 front doors?

Premium aluminium profiles, a durable and high-quality colour finish, excellent components and thick, protective and insulated thermal panels on our front doors, make Alunet doors stylish and with a luxurious look and overall feel. Above all they provide excellent security, energy-efficiency and functionality.   

Are aluminium front doors any good?

The benefit of choosing aluminium front doors starts with the slimmer and stronger frame profiles, with a much slimmer appearance than composite doors or timber front doors. With a little routine cleaning, the durable powder-coated finish continues to look good after many years compared to the fading of cheaper front doors. Other doors are also restricted in size for smaller doorways, aluminium front doors can be made smaller than composite doors. If you are also having aluminium windows on the property, the colour matching is also exact compared to other materials.

What is the best designer front door?

There are many doors on the market comprising a quality aluminium door and frame system enhanced with a decorative door panel. Some door panels only comprise basic insulation and thin aluminium skins. The better the door panel and glass quality, the better the designer front door. Thermally broken aluminium, quality door locks and key cylinders are also recommended.

Can i get aluminium French Doors with side panels?

The French door with side panels is incredibly popular as a door style right now. Alunet BF73 entrance doors are available with side panels. We can even customise your doors with hand-cut and applied glazing bars, giving the industrial or steel look.

How much are aluminium front doors?

The size, panel style, colour, hardware options and glass type all affect the price you pay for aluminium front doors. Contact us for a fast quotation.

Are aluminium doors better than composite doors?

Aluminium doors are slimmer, offer a wider range of sizes, and won’t fade, warp or twist. The overall fit and finish are often better because the door glass is glazed into the panel without using the “cassette” design of composite doors. Composite doors often don’t come small enough for narrow doorways found in cottages or Victorian houses. Aluminium doors can be made much narrower, wider and taller than any composite doors. As a result, with an aluminium door, you also don’t need a side or top panel to take up the remainder of a larger door opening.
