If you\u2019ve ever shopped for outdoor furniture, you\u2019ve probably spotted fiberglass pieces mixed in with wicker, metal, and wood options\u2014and for good reason. As a fiberglass furniture supplier, I get asked all the time, \u201cHow does it hold up in extreme cold?\u201d Most people assume fiberglass is just a thin, brittle plastic that shatters at the first sign of frost, but that\u2019s a myth we debunk every day with the furniture we manufacture and supply. Let\u2019s break down the science, what actually happens when fiberglass hits freezing temperatures, and why our clients keep coming back for more even in the coldest parts of the world. Fiberglass Furniture<\/a><\/p>\n

<\/p>\n

First, let\u2019s get clear on what fiberglass furniture is<\/em>\u2014because not all fiberglass is the same. A lot of people lump \u201cfiberglass\u201d in with generic plastic, but that\u2019s a critical mistake. The fiberglass we use in our products is a composite material: thin, interwoven strands of glass (hence the name) bonded together with a durable polymer resin, usually a type called thermoset polyester or epoxy resin. The glass fibers add structural strength, while the resin holds everything together, creates a smooth, weatherproof finish, and resists moisture, UV rays, and temperature fluctuations. That composite mix is why fiberglass furniture outperforms many other materials in extreme conditions, including cold weather.<\/p>\n

Now, let\u2019s talk about what extreme cold does to materials in general. Most materials expand when heated and contract when cooled, a process called thermal contraction. The rate at which a material contracts as temperatures drop depends on its coefficient of thermal expansion (CTE)\u2014a measurement that tells you how much a material changes in size with temperature changes. For context, common materials like steel have a relatively low CTE, meaning they expand and contract very little with temperature shifts. Natural wood has a high CTE, especially when it\u2019s damp, which is why outdoor wooden furniture often cracks or warps after a few cold winters. Generic plastic has a CTE even higher than wood, which is why cheap plastic patio furniture gets brittle and snaps when left out in freezing weather.<\/p>\n

Fiberglass, though, has a very low CTE. That means when temperatures plummet, it contracts very slowly and minimally, so it doesn\u2019t experience the kind of stress that causes cracking or warping. But here\u2019s the catch: not all fiberglass composites are created equal. The ratio of glass fibers to resin, the type of resin used, and how the fiberglass is molded all play a big role in how it reacts to extreme cold. At our factory, we use a 60\/40 glass-to-resin ratio for all our furniture, and we cure the resin at high temperatures to create a cross-linked structure that\u2019s extra rigid and stable. That\u2019s why our fiberglass pieces perform differently than the cheap, unbranded fiberglass furniture you might find at a big-box store\u2014their composites are often weaker, with less glass fiber and lower-quality resin, so they can fail in cold weather.<\/p>\n

So what actually<\/em> happens to fiberglass furniture in extreme cold, and when does it fail? Let\u2019s get into real-world scenarios. I\u2019ve been in this industry for 12 years, so I\u2019ve had clients test our furniture in temperatures as low as -40\u00b0F (-40\u00b0C) in northern Canada, Alaska, and parts of Scandinavia. In those conditions, here\u2019s what you\u2019ll notice: first, the finish might feel slightly harder to the touch. Fiberglass is soft and flexible at room temperature, but at freezing temps, it gets stiffer\u2014like how a rubber band feels solid when it\u2019s cold, instead of stretchy. That stiffness isn\u2019t a flaw; it\u2019s just a property of the polymer resin. Unlike cheap plastic, though, our fiberglass doesn\u2019t become brittle enough to shatter. I\u2019ve seen someone drop a metal chair leg on one of our fiberglass side tables in -30\u00b0F weather, and the only mark was a tiny scratch that sanded out with a bit of primer. The same drop would\u2019ve shattered a $20 Walmart plastic table into a dozen pieces.<\/p>\n

Another common question: does moisture and ice buildup damage fiberglass furniture in extreme cold? This is where the resin\u2019s weatherproofing comes in. Fiberglass is non-porous, so moisture doesn\u2019t seep into the material like it does in wood or concrete. When water gets on fiberglass, it beads up and runs off, instead of being absorbed. If water does get into a tiny crevice (say, between the seat and frame) and freezes, ice expands by about 9%, but the low CTE of fiberglass means it flexes just enough to absorb that expansion, without cracking. We do recommend that clients store their fiberglass cushions indoors during the coldest months, but the furniture itself? It\u2019s built to stay outside. I had a client in Minneapolis who left our 8-piece dining set on his uncovered deck for three straight winters, and when he checked on it last year, the only damage was a small chip on one armrest from a lawnmower, not cold-related cracking.<\/p>\n

That\u2019s not to say fiberglass furniture is invincible, though. There are extreme edge cases where it can fail in cold weather, and it almost always comes down to installation or use, not the material itself. For example, if you have a custom-built fiberglass furniture piece that\u2019s bolted to a concrete patio, and you don\u2019t leave any expansion gaps between the furniture and the concrete. Wait\u2014since fiberglass contracts in cold weather, if it\u2019s rigidly bolted down with no give, the contraction can pull on the bolts or even cause a small stress crack in the fiberglass at the bolt holes. We always include installation guides with our furniture that tell clients to use flexible rubber grommets when bolting pieces to hard surfaces to avoid that. Another mistake: using fiberglass furniture as a sled or a step stool to reach a high roof. We\u2019ve had a few clients do that, and the stress from uneven weight distribution on a cold, stiff piece can cause a break\u2014same as you\u2019d see with any hard material, including wood or metal. But that\u2019s misuse, not a flaw in the fiberglass itself.<\/p>\n

Let\u2019s also compare fiberglass to other common outdoor materials in extreme cold, because that\u2019s what our clients care about. Metal furniture, for example, rusts when exposed to moisture and freezing temps, even with powder coating. If a powder coating chips on a steel chair leg, rust will form under the coat, expand as it freezes, and eventually flake off the powder coat. Wood furniture needs to be sanded and sealed every 1-2 years to prevent cracking from frost, and even then, it can warp if it\u2019s left uncovered. Wicker furniture absorbs moisture, gets heavy in snow, and can rot or split when water freezes inside the fibers. Fiberglass doesn\u2019t have any of those issues. Our clients in cold climates save thousands a year on maintenance and replacement costs because their fiberglass furniture doesn\u2019t need sealing, doesn\u2019t rust, and doesn\u2019t crack from frost.<\/p>\n

I also want to address a common misconception that fiberglass furniture is \u201ccheap\u201d or \u201cflimsy\u201d because it\u2019s not as heavy as cast aluminum or wrought iron. That\u2019s another myth. Our fiberglass dining chairs weigh about 15 pounds each\u2014light enough to move around for patio parties, but sturdy enough to hold 300 pounds, even at 0\u00b0F. The key is the composite structure: the glass fibers run the length of the furniture frame, so they distribute weight evenly, rather than having a solid metal frame inside a thin metal outer shell. In cold weather, that lightweight, high-strength structure doesn\u2019t become brittle, because the resin is engineered to retain its flexibility within the composite matrix. We test every single batch of resin at our factory by cooling samples to -40\u00b0F and dropping a 10-pound weight on them\u2014if they don\u2019t crack, they get approved for use in our furniture.<\/p>\n

Over the years, we\u2019ve worked with everyone from small residential clients who want a durable patio set for their Minnesota backyard to commercial clients like resort hotels in Iceland that need furniture for their outdoor terraces, where temperatures stay below freezing for six months of the year. The feedback is always the same: they didn\u2019t realize fiberglass was this tough in cold weather until they used ours. Last year, a hotel client in Reykjav\u00edk ordered 50 of our lounge chairs, and their maintenance manager told us that after the first winter, not a single chair had a cold-related crack, compared to their old cast aluminum chairs that had 12 cracked frames to replace.<\/p>\n

So what does all this mean if you\u2019re considering fiberglass furniture for an extreme cold climate? First, make sure you\u2019re buying from a reputable supplier, not a random online retailer selling unbranded fiberglass pieces. Not all fiberglass is made equal, as I mentioned earlier\u2014cheap composites use less glass fiber and lower-grade resin that can become brittle in extreme cold. At our company, we stand behind every piece we supply with a 10-year warranty against manufacturing defects, including cold-related cracking, because we know our product works.<\/p>\n

Second, follow basic care guidelines to extend the life of your fiberglass furniture, even in extreme cold. As I mentioned before, store fabric cushions indoors during the winter (we sell weather-resistant replacement cushions if you need them), and use flexible grommets if you bolt furniture to hard surfaces. If you get a lot of heavy snow, you can brush it off your furniture occasionally, but you don\u2019t need to cover the furniture itself\u2014unlike wood or wicker, fiberglass doesn\u2019t need extra protection from frost.<\/p>\n

If you\u2019re tired of replacing your patio furniture every few years because it cracks or rusts in cold weather, fiberglass is the solution. It\u2019s not just a trendy, lightweight option\u2014it\u2019s a material built to handle extreme temperatures, moisture, and heavy use, without the maintenance of other outdoor furniture materials.<\/p>\n

<\/p>\n

At the end of the day, as a fiberglass furniture supplier, our goal isn\u2019t just to sell you a piece of furniture\u2014it\u2019s to sell you something that will last, no matter what the weather throws at it.
