Vinyl, composed of ethylene and chlorine, is the second most prevalent plastic polymer globally, known as polyvinyl chloride (PVC). This material forms the core of all vinyl window frames. However, not all vinyl windows are created equal. The quality heavily relies on the components included in the manufacturing formula.
Our vinyl windows incorporate more than just the basics. They feature specialized UV stabilizers that reflect harmful UV rays, preventing material degradation, and titanium dioxide ensures the windows are heat-stable and perform excellently under various conditions.

Premium Replacement Window Features for Northwest Homes
When it comes to replacement windows in the Pacific Northwest, quality and performance are essential. From constant rain to fluctuating temperatures, your windows must withstand the region’s unique climate challenges while delivering long-term energy savings, comfort, and security. The LW Del Mar Series from Lake Washington Windows and Doors is engineered specifically for Northwest homes, combining premium materials with innovative design. Below is a detailed overview of the standout features that distinguish our windows.
| Engineered LW XTRU™ Vinyl Frame | Our exclusive LW XTRU™ vinyl frame is infused with titanium dioxide for added strength, UV resistance, and thermal stability. It features fusion-welded corners that create an airtight seal, ensuring superior performance and longevity. |
| Foam-Insulated Architectural Frame | The LW Del Mar Series models are designed with low-conductance Comfort Core™ foam insulation, inserted into specific dead air chambers within the frame to enhance thermal performance and energy efficiency. |
| Weather-Tight Performance | Our antimicrobial triple-fin weatherstripping provides four layers of protection to block wind, moisture, dirt, and bacteria. This tight seal is key to maintaining comfort and indoor air quality during Seattle’s wettest months. |
| Heavy-Duty Screens with Antimicrobial Mesh | LW’s Aluma-Force™ heavy-duty screen frames are constructed with thick extruded aluminum walls and infused with antimicrobial protection, coated with watershed technology to improve visibility, airflow, and insect resistance. |
| Optional Sound Package | The LW Sound Package features varying glass thicknesses and argon gas layers, reducing unwanted noise by up to 50%. This feature minimizes sound wave bounce and vibration to keep your indoor spaces peaceful and quiet, even in urban or high-traffic areas. |
| Enhanced Security and Structural Reinforcement | Every window is built with fiberglass reinforcement and interlocking rails to resist forced entry. Locking hardware is firmly anchored to the frame and reinforced with a rigid fiberglass inner core, ensuring our windows exceed industry standards for structural integrity and break-in resistance, providing you with greater peace of mind. |
| High-Performance Glass Options | Del Mar Series windows come standard with LW Armor™, a peel-off film that keeps glass surfaces clean during transport and installation. Other key features include the 3-layer LW Infinit-e coating, PLUS Easy Clean Coating, the Platinum Elite Spacer, True Dual Seal, Moisture Stop, and Argon Gas insulation — all working together to provide unmatched energy efficiency and clarity. |
| Energy-efficient glass upgrade options | For added performance beyond standard double-pane insulation, consider premium upgrades like LW SunMatrix, which blocks 99% of UV rays with a 4-layer Low-E coating, or LW QuadraTherm, which utilizes multi-layer heat retention technology for maximum insulation. LW SunShield features a blue-gray exterior tint that reduces glare and minimizes solar heat exposure, making it ideal for south- and west-facing windows. |
| Premium Glass Features & Upgrades | LW SR50 Sound Reduction Glass comes standard with Del Mar windows and reduces outside noise by up to 50%. Optional upgrades include First Guard Laminated Security Glass, which meets ASTM F1233 standards for forced entry protection, and LW 4X Tempered Safety Glass, which is up to four times stronger than standard glass and shatters in small, break-safe pieces to reduce injury risk. |
| Exclusive Leak Armor™ Installation | Every LW Series vinyl window installed by Lake Washington Windows and Doors features our patented Leak Armor™ installation method, specifically designed for the Pacific Northwest’s wet climate. It adds an extra layer of waterproofing protection around the window opening. Flashing tape integration, multiple moisture barriers, and expert sealing techniques prevent water intrusion at the most vulnerable points. |
| Limited Double Lifetime Warranty | Your investment is protected by one of the most comprehensive warranties in the industry. The LW Series comes with a limited double lifetime warranty that covers both the product and the installation, providing peace of mind for as long as you own your home. Even better, this warranty is fully transferable to the next homeowner, adding to the resale value and providing assurance for future buyers. |
Vinyl Window Options for Every Window Style
Whether you need a traditional or contemporary style, Lake Washington Windows and Doors offers a vinyl replacement window that suits your needs. We proudly offer options in all eight of the primary home window styles:
Picture windows are fixed and don’t open, offering an unobstructed view of the outdoors and flooding your space with natural light. They enhance your home’s architectural aesthetic, serving as a striking focal point in design.
Hinged at the side and opening outward, casement windows provide excellent ventilation. Operated with a crank or lever, casement windows also feature a tight seal for superb insulation.
Single-hung windows feature a fixed top sash and a movable bottom sash that slides vertically, making them a cost-effective and popular choice. They offer a traditional appearance and are simpler to install than more complex window styles.
Double-hung windows have two operable sashes, top and bottom, instead of only one operable bottom sash, providing better ventilation and an added level of safety for homeowners with small children.
Awning windows are hinged at the top and open outward from the bottom, shielding against rain while enhancing ventilation. Their unique design is perfect for adding airflow above doors or other windows.
Designed to save space, sliding windows feature one sash that slides horizontally over another, making them ideal for areas with limited exterior space, such as walkways, patios, or along busy streets.
Bay and bow windows project out from the wall to create a curved appearance that adds space, volume, and light to any room. They offer expansive views and are a dramatic centerpiece in large spaces such as living rooms, dining rooms, or master suites.
Customized to fit unique spaces and design schemes, our specialty-shaped windows offer endless customization possibilities. These windows can be designed to fit virtually any dimension and shape, adding unique character and distinction to your home.

FAQs – Seattle Vinyl Windows
Do vinyl windows increase home value?
Absolutely. Due to the high performance and design options, vinyl windows generally increase the value of most homes, especially those with older, inefficient windows.
How do vinyl windows compare to fiberglass windows?
When considering different materials for windows, vinyl represents a solid, cost-effective option, as it is a material that will provide a strong return on investment (ROI) for your new windows.
Fiberglass windows top the chart in terms of durability and energy efficiency, but they come at a higher price. Vinyl windows, on the other hand, provide commendable performance at a more accessible price point, making them ideal for value-conscious homeowners.
The choice between these materials often comes down to aesthetic preference. However, vinyl windows are the most economical for those looking to maximize value due to their lower material costs.
Should I replace all my windows at once?
While replacing all your windows at once is unnecessary, doing so can improve your home’s value and energy efficiency, lower your utility bills, and provide enhanced security. Additionally, we can offer a better price when ordering in quantity versus individual replacements.
What makes vinyl such an energy-efficient window material?
Vinyl is an energy-efficient window material because it is an excellent insulator, manufactured to be impervious to weather, low-maintenance, and lightweight while still providing the insulation needed to reduce heat loss in winter and heat gain in summer, resulting in lower overall energy consumption.
How long do vinyl windows last in Seattle’s climate?
High-quality vinyl windows, such as the LW Series, are built to last 30 years or more, especially when installed using moisture-resistant methods like our Leak Armor system.
Do vinyl windows require any maintenance?
Vinyl windows are virtually maintenance-free. They don’t require painting, staining, or sealing and can be easily cleaned with mild soap and water.
Will vinyl windows warp or discolor over time?
Our premium vinyl windows are made with titanium dioxide-infused material to prevent warping, chalking, and discoloration. This ensures long-term durability, even in the face of constant exposure to UV rays and moisture common in the Seattle area.
Can I customize the look of my vinyl windows?
Yes. Our LW Series vinyl windows come in a wide range of exterior colors, interior finishes, hardware upgrades, grid patterns, and obscure glass styles.
Are vinyl windows secure?
Absolutely. The LW Series includes reinforced fiberglass frames, secure cam locks, optional True Action auto-locking systems, and even stainless steel sash deadbolts on sliding windows. Combined, these features provide reliable protection against forced entry.
