Fiberglass Building Products' pultruded Fiberglass Gutters look just like traditional wood, but are easier to install and don’t rot. And now, thanks to a new manufacturing process, the company has halved the product’s cost, from $30 to $15 per lineal foot. The gutters are made to mimic 4x5 and 4x6 wood gutters in 27.5- and 40-foot lengths, and require almost no maintenance (aside from typical cleaning of leaves and debris). They’re white but can be coated with any latex paint.
