Reasons Modern Replacement Windows are Better than Ever

As you can guess, replacement windows have come a long way in the last few decades. Things that were once standard are completely obsolete. Even windows that are only 20 years old don’t measure up to some of the new replacement windows in Seattle, WA. You might be surprised at how far the industry has come. Here are just a few things that have changed making new windows safer, more efficient, and less maintenance than ever before:

Modern Frame Materials

In the past, there were not many options when it came to choosing windows. Wood and metal were the standards for both replacement windows and new construction windows. Today there are more choices. The most popular options include wood and aluminum, but there are also fiberglass and vinyl windows as well as some composites. Each material comes with unique characteristics and you are sure to find a product that suits the needs, style, and budget of your home.

Multiple Panes of Glass

In the past, only one pane of glass protected the home from the outside elements. That didn’t provide very much insulation or protection. The modern standard is now two panes of glass with a space between sealed as a single unit called an insulated glazing unit (IGU). This advancement cut down on unwanted heat transfer making windows better insulators. It also helped windows last longer and make homes more secure. But that was just the beginning. Now manufacturers can make replacement windows with three or even four layers of glass for more extreme climates. Because of this technology, the inside pane of glass is the same temperature as the indoor air.

Inert Gas Fills

Normal air used to fill the space between the panes of glass on IGUs. But it would retain moisture and expand and contract with temperature changes causing broken seals. Today manufacturers use different types of noble gas between the panes. They are colorless, odorless, and non-toxic. But they have a higher density than air and help block the transfer or radiant heat. This means homes stay cooler in summer and warmer in winter. The most common gasses used in modern windows include argon, krypton, and xenon.

Laminated Glass

Old windows used to break into large and dangerous shards on impact. Today the technology used on car windshields is also used on home windows. Laminated or tempered glass goes through a special manufacturing process to ensure that if the glass breaks it shatters into smaller, almost cubic pieces that are less dangerous. You can even get impact-resistant glass that has two layers adhered to an interlayer of polyvinyl butyral (PVB). With this technology even though the glass may break, it remains largely intact.

If your windows are more than 20 years old you should start thinking about upgrading with replacement windows in Seattle, WA. The innovations and technologies of these new products will improve your home in a number of ways. For more information, visit Signature Window & Door Replacement at 22613 68th Ave. S.

I cannot praise Signature highly enough. We hired them in 2012 to replace all of our windows and two sliding doors - the work was excellent and we love our Simonton windows. We just hired them again to rebuild our two-story entryway and install a Perva door and new windows. From the very thorough conversations with our salesperson, Vitaliy, to the scheduling with the office staff, to the actual installation - everything is as professional and high quality as you can find. We gathered quotes from three other companies but none of them went to any effort to truly lay out how the job would be accomplished. Photos show the old & new interior side, and the new exterior. Still needs painting but we're so happy!

After an extensive vetting process and comparing multiple options, I confidently chose Signature Windows & Doors for my home, and they absolutely delivered. The Marvin brand windows they installed are beautiful and of incredibly high quality—the craftsmanship speaks for itself. Beyond the great product, the installation process was truly exceptional. The crew was professional, precise, and made the entire project seamless from start to finish. I highly recommend them to anyone looking for top-tier windows and flawless execution. I had a fantastic experience with Signature Windows & Doors.

We called our project "The Window From Hell." It was a HUGE trapezoid window up high in a 2-story living room, and it needed to be replaced after its seal failed. I got bids, and was the most impressed with Danny L at Signature Windows. We had a tight deadline because the home was going on the market and access to the window, especially in the rain, was really challenging. Meeting the deadline, and the safety of the installers, were non-negotiable. Danny came out the very next day to measure the Window From Hell and, not only did he give me the best price, but his company was the only one that had all the scaffolding equipment readily available at no extra charge. The window arrived sooner than expected, and installation was quickly scheduled to meet the deadline. Then we hit a snag: some epic rain made the cedar roof too slippery for safe conditions. Brent and his crew of expert (and very brave) installers rigged up a safe way to haul this brand-new Mother of ALL Windows up to the second floor and install it using very long ladders, secure scaffolding, and harnesses. I think we had 4 or 5 installers for this job. It took all day to get the old Window From Hell out and the new Mother of All Windows installed. But what a job! Perfect caulk lines, perfect cleaning of the glass, perfect clean-up of the job site, indoors and out. Job done ON TIME, SAFELY, and at an excellent price. If Signature can handle my Window From Hell, I am very confident they can install ordinary double-hung windows that exceed your expectations for quality, price, timeliness, and workmanship. I highly recommend Signature Windows.

Everything from the initial consultation, regular updates on my order and installation was wonderful. The most recent installation was the third time I've had Signature replace old windows and I've been so pleased every time. They took the time to explain which windows needed replacement and provided options without any sales pressure. It's so nice to work with a company that believes in great customer service and offers quality products.

We have chosen to work with Danny and his team at Signature Window & Door twice now. We love the quality of the windows and the help they provide in the design process all the way to the finished installation. We put in a 15' folding door at our last home. It was a showstopper! Highly recommend them to bring your home back to life with beautiful windows that are built to last!

We bought a house that needed all new windows & sliding glass doors replaced. So we did our research and visited window replacement companies to see & touch different window & screen types. We decided to work with Signature Window primarily based on customer service as we received during the research & planning process with Office personnel (friendly, helpful, responsive) & Sales team (product knowledge, design assistance, open & honest).

1st Project (Aug 24) - 8 windows & 1 Sliding Door
2nd Project (Feb 25) - 1 ceiling to floor large window & 2 windows
Product of windows & door was excellent - we are extremely happy.

The customer service experience was superb. We worked with Sales Rep, Scheduler, Window Measuring Rep & Installers - all were friendly, open & honest, communicative, assisted with design & product knowledgeable. Installers did an awesome job with project cleanliness & kept busy all day long.

We are extremely satisfied with our overall experience with window replacement with Signature Windows 🥰
