A lot of companies talk about

Corners joined three ways for superior strength
Mortise-and-tenon technology—Creates a strong interlocking wood joint made by fitting
a mortise in one board and a matching projecting member (tenon) in the other, snapping the two sides together like a puzzle.
Strong and durable exterior-grade glue—Stronger than the wood it bonds. It seals each corner joint together.
Metal fasteners—Finalize the joint and hold it secure.
Pella factory-tests every venting window for air infiltration to ensure it meets or exceeds industry standards. If it doesn’t
pass, it doesn’t ship! Most other manufacturers only do random testing.
testing laboratory—One of the best in the industry. We continually test every component of Pella® Windows
& Doors under the harshest conditions—the burning rays of the sun, salt air, acid rain, excessive humidity, extreme
hot and cold temperatures, high wind and driving rain to assure our products will perform the way we say they will, day after
World-class manufacturing—Pella’s manufacturing processes are continually evolving
and improving so we can continue delivering the highest quality and latest innovations to our customers.
Factory assembly—Pella uses factory-controlled processes to manufacture over 50 different combinations of windows and
entry doors that are immediately ready to install. Many other manufacturers’ products require assembly at the job site,
which could result in questionable quality.
