Correx vs Aluminium Estate Agent Boards | Kremer Signs
Thursday, August 27, 2026
Choosing the right material for your estate agent boards is one of those decisions that can appear straightforward until you start weighing up the variables. Budget, durability, branding quality, board lifespan and the conditions your boards will face in the field all play a part. For estate agents across the UK, the two most widely used materials are corrugated plastic, commonly known as Correx, and aluminium. Both have a well-established place in the property signage market, and both serve different agency needs effectively when matched to the right circumstances.
At Kremer Signs, we have been manufacturing estate agent boards since 1985, which gives us a perspective on this question that goes well beyond materials data sheets. Here is how the two options compare, and what to consider when deciding which is right for your agency.
What Are Correx Estate Agent Boards?
Correx is a twin-wall corrugated polypropylene sheeting, lightweight and cost-effective to produce. It has been the standard material for short-term and mid-term property signage for many years, and for good reason. Boards produced from Correx are economical to order in volume, easy to handle during erection and removal, and perfectly adequate for the typical duration of a sales or lettings instruction.
For agencies with high board turnover, busy lettings departments or a need to manage signage costs across multiple branches, Correx boards offer a practical and proven solution. Print quality on Correx has improved considerably over the years, and when produced to the standards we operate at across our facilities in Newbury, Bristol, Birmingham and Lincoln, a Correx board presents your agency branding clearly and professionally throughout its working life.
The key consideration with Correx is longevity. In sustained exposure to UV light, heavy rain or physical impact, Correx boards will show wear more readily than aluminium. For shorter instruction cycles or where boards are regularly refreshed as part of standard operations, this is rarely a significant concern. Where boards are expected to remain in position for extended periods, particularly on new homes developments or high-profile instructions, a more durable material may be the better investment.
What Are Aluminium Estate Agent Boards?
Aluminium boards offer a step up in durability and perceived quality. The material is rigid, weather-resistant and capable of holding print to an exceptionally high standard over a longer working lifespan. For estate agents who want their signage to make a strong visual impression, aluminium boards carry a weight and finish that communicates quality before a buyer has even read the details.
Aluminium is particularly well-suited to premium property markets, new homes developments and any situation where boards will be in position for an extended period. A well-produced aluminium board can withstand the British climate far more effectively than Correx, making it a sound longer-term investment for agencies where board condition reflects directly on brand perception.
The trade-off is unit cost. Aluminium boards carry a higher price per board than Correx, which is a relevant factor for agencies ordering at volume or managing tight budgets across a large estate agency network. That said, the extended lifespan of aluminium boards means the cost per instruction can be more competitive than it first appears when calculated across repeated use.
How to Decide Which Is Right for Your Agency
The honest answer is that most estate agencies benefit from both materials, deployed according to purpose. Understanding your own operational patterns is the starting point.
If your agency handles a high volume of lettings where boards move frequently between properties, Correx is likely the practical choice for the majority of your stock. If you operate in a premium sales market, manage a new homes site or want your for sale boards to hold their appearance over a longer instruction, aluminium is worth the additional investment. Our board types page sets out the full range of options available, which can help you match the right format and material to your agency's specific requirements.
Branding consistency matters too. Whether you choose Correx or aluminium, the quality of print and finishing should be held to the same standard. At Kremer Signs, both materials are produced entirely within our UK facilities, with no reliance on third-party manufacturers. Every board leaves our production floor finished to a standard that reflects well on the agencies whose names appear on them.
Making the Most of Your Signage Investment
The board material is one part of a broader signage strategy. The post specification, fitting hardware, design quality and ordering process all contribute to how effectively your agency is represented in the field. As the UK's largest supplier of estate agency boards, Kremer Signs provides all of these elements under one roof, from boards and posts through to office signage and new homes developments.
