Marketed as "Pella's best performing window," Impervia windows feature: Fiberglass construction - The fiberglass frame and sashes make Impervia windows strong, durable, and dimensionally stable. Fiberglass holds up well in all climates and won't swell or warp like wood or vinyl. AdvancedLow-E insulating glass - Impervia windows use Pella's most advanced Low-E glass coating to reduce heat loss in winter and block heat gain in summer. This boosts energy efficiency. Argon gas fill - The gap between the panes is filled with argon gas, which further improves thermal efficiency. Optional triple pane glass - For maximum efficiency, Impervia windows can be upgraded to triple-pane glass. Tight construction - Pella uses its EnduraGuard wood protection to seal all exposed wood surfaces. Foam insulation seals the frame and sashes tightly. High performance ratings - Impervia windows meet ENERGY STAR® requirements in all 50 states. They exceed criteria for the strictest energy codes. Premium exterior finishes - Choose from multiple woodgrain finishes, along with painted exterior colors. The durable finishes withstand weathering and keep their good looks over time.

They're built to last for decades while providing superior energy savings. Pella Lifestyle Series Windows Overview Pella Lifestyle series windows sit one tier below Impervia in Pella's lineup. Key features include: Vinyl or fiberglass frames - Lifestyle windows come in both vinyl and fiberglass frames. Fiberglass is more durable but vinyl costs less. Both resist swelling, rotting, and warping. Low-E insulating glass - Pella's standard dual-pane Low-E glass comes standard. It blocks heat gain and controls heat loss. Argon gas fill - Just like on Impervia, argon fill between the glass panes adds insulating value. Optional triple pane glass - Triple pane glass can be added to boost efficiency further. Moisture barriers - Lifestyle vinyl windows get a 3-layer moisture barrier. Fiberglass models get Pella's EnduraGuard protection. ENERGY STAR compliance - Performance meets or exceeds ENERGY STAR requirements in all climate zones. Affordable price point - As a mid-range series, Lifestyle windows are priced below Impervia models. More homeowners can afford them. The Pella Lifestyle series hits a sweet spot between performance and price. The fiberglass and vinyl frames don't offer the ultimate longevity of Impervia, but Lifestyle windows still deliver attractive, energy-efficient windows with Pella's quality. Key Differences Between Pella Impervia And Lifestyle Windows Now that we've covered the highlights of each Pella window series, let's do a detailed comparison. Materials Comparison One of the biggest differences between Pella Impervia and Lifestyle is the frame material: Pella Impervia Fiberglass frames and sashes Pella Lifestyle Vinyl or fiberglass frames Vinyl sashes Fiberglass is the clear performance winner when it comes to frame materials. Fiberglass has exceptional strength and durability. It won't swell, shrink, rot, or warp like wood or vinyl. Maintenance is minimal. Fiberglass withstands weather extremes beautifully in all climates. It will look great for decades. Impervia's fiberglass construction gives it a leg up over Lifestyle's vinyl models. However, Lifestyle fiberglass frames offer similar durability and performance. Vinyl windows like Lifestyle are affordable, energy-efficient, and perform well in most climates. Extreme heat can make vinyl windows sag a bit. Cold weather makes vinyl prone to becoming brittle. Overall, vinyl requires less maintenance than wood but doesn't match fiberglass for durability and dimensional stability. On materials alone, Pella Impervia is the clear winner thanks to its full-fiberglass construction. But Lifestyle vinyl windows still perform admirably if fiberglass is beyond your budget. Glass Comparison Both Impervia and Lifestyle windows use high-performance Low-E insulated glass. But there are some key differences: Pella Impervia Pella Impervia Windows Advanced3 Low-E glass Optional triple pane Pella Lifestyle Standard dual-pane Low-E Optional triple pane Impervia windows come with Pella’s most advanced triple-layer Low-E coating. This blocks heat gain and reduces heat loss even better than standard Low-E glass. Both window lines offer triple pane glass as an upgrade. The extra pane further lowers U-Factors (improves insulation). It also blocks more noise. Overall, while Lifestyle windows have good glass, Impervia wins again with its top-tier Low-E coating. Triple pane upgrades are excellent for either line if you want maximum efficiency. Efficiency Comparison Let's look at some key efficiency specs: Pella Impervia U-Factor down to 0.17 (vinyl), 0.16 (fiberglass) SHGC as low as 0.19 ENERGY STAR certified in all climate zones Pella Lifestyle U-Factor down to 0.27 SHGC as low as 0.22 ENERGY STAR certified in all climate zones U-factor measures how well a window insulates. The lower the U-factor, the better the insulation. Impervia windows go down to 0.16 thanks to triple pane upgrades, beating out Lifestyle's lowest 0.27 U-factor. SHGC (solar heat gain coefficient) is the fraction of heat from sunlight transmitted through a window. Lower SHGC is better to reduce heat gain. Lifestyle and Impervia have similarly good SHGC ratios. Both window lines achieve ENERGY STAR certification in all climate zones. But Impervia exceeds requirements by a wider margin. Overall, Impervia offers better thermal efficiency, while Lifestyle still performs very well. Both will cut energy bills substantially compared to old windows. Cost Comparison With their premium construction and materials, Pella Impervia windows are one of Pella's most expensive window lines. Lifestyle windows cost significantly less. According to Pella, you can expect to pay around 25-40% more for Impervia versus comparable Lifestyle windows. The exact price difference depends on the size, options chosen, and location. Here are some example price ranges: Basic Lifestyle vinyl double hung window: $300-$500 Similar Impervia window: $500-$800 Large Lifestyle fiberglass picture window: $1,000-$1,500 Similar Impervia window: $1,500-$2,500 While not cheap, Lifestyle windows are a good value that makes Pella quality more affordable. The exceptional durability and performance of Impervia commands a premium price. When choosing, weigh the higher cost of Impervia against benefits like longevity, resale value, energy savings, and added comfort. It's often worth investing more upfront. Warranties The warranty coverage reflects the materials and construction of each Pella window series. Pella Impervia 20-year coverage on glass, hardware, parts, and labor 10-year coverage for exterior finish and screens Lifetime limited warranty on fiberglass components Pella Lifestyle Pella Lifestyle Series 10-year coverage on glass, hardware, parts, and labor 10-year coverage for exterior finish and screens Lifetime limited warranty on fiberglass components 10 years coverage on vinyl components Impervia warrants all components for twice as long as Lifestyle, showing the confidence Pella has in their durability. For ultimate peace of mind, choose Impervia. But Lifestyle warrants all materials appropriately based on expected lifespans. Appearance Both Impervia and Lifestyle windows combine bold, clean lines with attractive finish options: Pella Impervia Exterior Rich woodgrain fiberglass finishes Custom factory-painted colors Simulated divided lite (grids between panes) Pella Lifestyle Exterior Woodgrain vinyl finishes Factory-painted vinyl Simulated divided lite For interior woodgrain, Pella uses pine for both window lines. And identical hardware options are available. Overall, appearance is similar for both series. But Impervia looks a bit more graceful and upscale thanks to the finer detail of real woodgrain fiberglass. Which Is Better Overall? When comparing Pella Impervia vs. Lifestyle windows, Impervia is the clear winner in most categories. The full fiberglass construction, Advanced3 Low-E glass, and premium warranties make Impervia a top choice if you want Pella's very best windows. However, Pella Lifestyle windows still perform very well. The vinyl and fiberglass frames are durable and energy-efficient. Just expect a shorter lifespan compared to Impervia fiberglass. Lifestyle windows cost significantly less than Impervia, making them a great option if you want better performance than builder-grade vinyl windows without breaking the budget. Here's a quick recap comparing Pella Impervia and Lifestyle windows: Pella Impervia Best for: Ultimate durability, energy efficiency, sound insulation, and premium performance Material: Fiberglass frame and sashes Glass: Advanced3 Low-E, optional triple pane Price: Expensive, 25-40% more than Lifestyle series Pella Lifestyle Pella Lifestyle Best for: Good performance and features at an affordable price Material: Vinyl or fiberglass frame, vinyl sashes Glass: Standard Low-E, optional triple pane Price: Mid-range, costs significantly less than Impervia In most cases, if your budget allows, choosing Pella Impervia gets you the very best windows Pella offers. But you can save substantially with Lifestyle windows while still getting better-than-average efficiency and quality. Is Pella As Good As Andersen Windows?
