When it comes to building materials, fire resistance is a critical factor for every homeowner. Lath and plaster is one age-old technique that is still used today. If you’re wondering whether lath and plaster walls can help protect your home during a fire, the answer is a strong yes. At GONZALEZ PLASTERING, we have worked on countless homes where plaster walls added an extra layer of safety and peace of mind.
The Natural Fire-Resistance of Plaster
Plaster is made from materials like gypsum, lime, and sand — all naturally fire-resistant substances. Unlike drywall, which can burn or crumble quickly under extreme heat, plaster walls create a dense, durable barrier that slows down the spread of flames. This means in the event of a fire, plaster surfaces can buy homeowners crucial extra minutes to react and evacuate safely.
How Lath and Plaster Systems Work Against Fire
A traditional lath and plaster wall system consists of thin wooden laths covered by multiple coats of wet plaster. Once dried, these coats create a thick, hard surface that naturally resists high temperatures. The combination of dense plaster layers and tightly packed lath boards helps slow the fire’s penetration compared to more modern, lightweight materials.
GONZALEZ PLASTERING uses the highest-quality materials and expert techniques to ensure every lath and plaster wall is crafted for both beauty and safety.
Why Historic Homes Are Often Safer Than You Think
Many older homes with original lath and plaster walls have proven to be more resilient during house fires than newer constructions. The dense structure of traditional plaster doesn’t ignite easily and doesn’t contribute significantly to fueling a fire. That’s why maintaining or restoring your home’s original plaster walls is not just about preserving charm — it’s also about improving safety.
Lath and Plaster vs. Drywall: Which Offers Better Fire Protection?
While modern fire-rated drywall options are available, standard drywall does not match the fire resistance of authentic plaster walls. Drywall is lighter and contains paper facing, which can ignite faster Plaster and lath walls, on the other hand, are denser, heavier, and much more resilient to heat and flame damage. Homeowners aiming for a safer, more durable option often prefer the timeless quality of lath and plaster construction.
