An aluminum ladder will be lighter than a fiberglass ladder, which makes it easier to carry. It can be a far more portable option for those moving from one job to another. Another big advantage of aluminum ladders is the price.
On the other hand, if there are no electrical power sources in your work area, the aluminum ladder is the lightest weight when compared to fiberglass or wood. There are also several kinds of ladders manufactured for a variety of uses.
Aluminum ladders are among the lightest options, with some weighing as little as 20 pounds. Fiberglass options tip the scale at around 50 pounds and may require a bit of heavy lifting.
Fiberglass ladders are typically stronger and more rigid than aluminum ladders, but, as we mentioned above, they’re also heavier. While they come in varying sizes capable of supporting varying weights, heavy-duty models support a maximum of 375 pounds.
Kit Denison: Aluminum is stronger than fiberglass. … There is also more flexibility where you want to put the weight in fiberglass. For instance, you could build lighter parts higher up. The heavier weight of fiberglass provides a more stable ride.
The Little Giant® HyperLite™ extension ladder is the lightest Type IA 300 lbs-rated fiberglass extension ladder in the world, bar none. The patent-pending HyperLite weighs up to 40 percent less than the leading competitor’s standard fiberglass ladder without sacrificing strength and stability.
Lightweight Is Key Today’s lightweight aluminum ladders save your back because they can extend up to heights comparable to heavy-duty steel or fiberglass extension ladders at a fraction of the weight.

Wooden ladders are not conductive to electricity, but they can rot when exposed to moist conditions over time. Fiberglass ladders offer the best choice for both for long life and safety from electrical conductivity.
A fiberglass ladder that has not been maintained at all can be expected to last between one and three years, but its lifetime can be extended by periodic washing and waxing.
On most two-story homes, this can only be done with a 28′ extension ladder. (This 3′ extension rule also holds true indoors and for shorter heights like one-story dwellings; you’ll just need a shorter ladder.)
Fiberglass boats tend to weigh more, so they generally have better seakeeping abilities and more stability than aluminum boats. Their higher weight means fiberglass boats don’t get easily buffeted by the wind, so they tend to drift slower and more predictably (a trait important to anglers, in particular).
Pros. The biggest advantage that aluminum has over fiberglass is its weight. These types of boats are usually 40% lighter than fiberglass, which gives them a great amount of speed. They’re also easier to transport.
Firstly fibreglass is heavier than aluminium allowing the hull to break through waves easier. This results in less lift and push from chop and waves leaving the boat more stable during the ride and less likely to slap. … These factors combined result in design that slices through the water superior to any aluminium boat.

It is resistant to weathering, won’t weaken with corrosion or rust, or suffer loss of strength or integrity when exposed to water. As a result, fibreglass is a safe choice that will last for generations. Werner is the world’s largest manufacturer of fibreglass ladders.

Electrical Conductivity For most tasks, an aluminum ladder is ideal; however, if you are working around electricity, you need to use a fiberglass ladder, instead. Unlike its aluminum counterpart, fiberglass ladders are non-conductive, making them the safer choice when working with electricity.
The obvious thing to start with is that metal ladders (such as aluminium and similar materials) should never be used when dealing with electricity, because of their conductive nature. … These consist of overhead, uninsulated power cables supported on wooden poles or insulators on metal structures.
Use non-conductive wood or fiberglass ladders when working near power lines.
Another concern when dealing with a fiberglass ladder, is cracking. While aluminum ladders are prone to dents, fiberglass ladders on the other hand, can crack, usually as a result of impact. Prevent cracks by not throwing your ladder out of a truck or letting it fall.
However, no matter how tired you’re feeling, fibreglass extension ladders and fibreglass step ladders must always be moved and stored indoors. When exposed to sunlight, fibreglass material can break down. This means the quality of your ladder will deteriorate and ladder safety compromised.
Fiber bloom occurs in fiberglass after years of outdoor service, which can affect ladders made from the material. The sun’s UV rays damage the fibrous properties of the ladder and expose the glass fibers. The condition is aesthetic and typically doesn’t affect ladder strength.
