Bringing old buildings up to modern fire safety standards can be tricky, especially when you’re working with listed properties. In places like London, where history meets tight space and constant use, it’s common to see older materials sitting beside new installations. Choosing the right wall materials matters a lot. It’s not just about matching the look. We also have to think about what’s happening behind the surface and how it holds up in a fire.
A proper fire resistant wall covering helps stop fire from spreading and gives more time for people to get out and help to get in. At the same time, we need to protect what makes heritage properties special. In this guide, we’re looking at how to balance both, how to choose wall coverings that meet fire protection standards without losing the building’s character.
Respecting English Heritage Design Rules
When working with listed buildings, we can’t just pick any product or slap up new materials. These projects come with rules that guide what kinds of changes are allowed, especially on visible finishes like walls.
Keeping original detail is often a top priority. So we aim to work around carefully kept plasterwork, panelling, or timber where possible. That might mean applying a covering that mimics the style of the original, or choosing colours and patterns that align with the time period.
At the same time, we look for ways to bring in safer materials. Some fire rated wall coverings are now made to match the look of more traditional textures, like limewash or wood grain. In many cases, conservation teams allow updates when:
• The fire upgrade fits within the original design and does not hide or damage historical details
• Any new detailing added can be recognised as modern, but still blends well with the rest of the space
• The new wall finish supports long-term upkeep and avoids future damage to original surfaces
When done right, wall coverings can support both safety and design, all while helping the original space stay true to its roots.
Balancing Safety with Original Building Materials
One of the hardest parts of updating a listed building is working safely around old materials. That might mean 150-year-old timber lath walls or crumbling horsehair plaster. These materials may be beautiful, but they often need backup when it comes to fire protection.
We have found that the best approach is to look for surface coverings and backing layers that give added protection without locking in moisture or adding too much weight. Some coverings can go directly over brick or timber. Others may need a semi-rigid board or base that serves as a fire barrier and a surface to mount onto.
Here are some smart ways we work safely with older materials:
• Use breathable wall layers that allow historic materials to breathe and adjust with moisture conditions
• Choose thin fire rated panels that can sit on top of existing walls without removing what is behind them
• Plan for service access points (like wiring or vapour barriers) so future works don’t disturb the protected structure
Many older buildings were never built with fire spread in mind. That is why adding proper protection now can make a real difference without affecting their original build.
How Fire Resistant Wall Coverings Work in Listed Spaces
A fire resistant wall covering is not just for show. It helps limit flame movement, slows smoke spread, and guards the wall structure underneath. In heritage buildings, this can mean the difference between minor damage and complete fire loss.
To count as fire resistant, a wall material must meet certain safety scores based on how it reacts to heat and flame. Some common options that meet the mark include fibreglass-reinforced panels, treated timber cladding, and specially tested fabric wall systems. At ATOL Construction, fire resistant wall coverings sit alongside other passive fire protection services such as fire compartmentation and fire door upgrading, so wall surfaces, openings, and structure all work together in a fire.
When we fit these coverings, we pay just as much attention to what is behind the surface. Cables, gaps, and supports all need proper shields so that hidden routes for fire or hot gases do not undo the surface protection. In data centres that operate out of listed buildings, for example, a mix of modern connectivity and old wall fixtures can bring added risk.
Fire protection for data centres depends on alarms and suppression systems, but also on walls and surfaces doing their job. That is why full wall build-ups, both front and behind the boards, need close planning. Our aim is to make every part of the wall help slow fire spread.
Common Mistakes Seen in Heritage Projects
We often fix fire protection problems in older spaces that have been updated without clear plans. The wall coverings look new, but they have not made the building any safer.
These are some of the most common mistakes we see:
• Gaps behind panels left untreated, letting smoke slip through
• Using glue or backings that do not meet fire ratings and can actually catch fire themselves
• Coverings that are installed tightly over original wood or plaster, trapping in moisture and causing long-term damage
• Skipping post-build checks, which can miss installation faults or changes made along the way
It is not always the big details that weaken a wall’s fire performance. Often, it is the little steps skipped because the focus was only on finishes, not fire.
The Safer Way to Update Listed Walls
We have learned that proper updates in heritage spaces almost always start with good planning. That includes looking at both visible finishes and what is inside the wall. Any updates should respect what is original, but still make the space safer.
It does not need to be all or nothing. With careful selection and installation, it is possible to keep the spirit of older spaces while helping protect the people inside. A thoughtful fire resistant wall covering makes all the difference, adding a needed layer of safety without changing the character of the building. Our experience on landmark heritage projects, including the Royal Albert Hall in London and Canterbury Cathedral in Kent, shows how important it is to coordinate fire upgrades closely with conservation goals.
Professional support helps test materials, check for gaps, and make sure fire resistance starts where it matters. When heritage walls are upgraded this way, they are not only more beautiful, they are stronger, safer, and better suited for modern use.
Planning fire protection upgrades in listed and heritage buildings across London calls for solutions that balance safety with preservation. Smart planning and the right materials, like a tested fire resistant wall covering made for sensitive spaces, can help protect your property’s legacy. ATOL Construction offers expert guidance and complete installation planning to make sure your upgrades respect both the character and future of your building.
