ASWF Twilight™ 35

Why Twilight 35 is the #1 Recommended Film in Las Vegas

Las Vegas averages over 300 sunny days per year. The Twilight 35's 55% TSER means it rejects more than half of all incoming solar energy before it enters your home — reducing cooling load without making your windows look like a mirror or a cave.

The 34% VLT keeps rooms bright and natural while the 63% glare reduction eliminates the harsh afternoon sun that washes out screens and causes eye fatigue. It is the balance point that most homeowners and business owners land on after comparing the full ASWF lineup.

What 55% TSER Actually Means

TSER (Total Solar Energy Rejected) is the most important number on a window film spec sheet. It measures the percentage of the sun's total energy — including visible light, infrared, and UV — that the film prevents from entering your space.

At 55%, the Twilight 35 blocks more than half of all solar energy. For a typical Las Vegas home with 200 sq ft of sun-facing glass, that translates to a measurable reduction in HVAC runtime and monthly energy bills.

99% UV Rejection — What It Protects

• Hardwood floors and tile grout from fading
• Furniture fabrics, leather, and upholstery
• Artwork, photographs, and wall paint
• Skin — UV exposure through glass is a documented health risk

ASWF's 99% UV rejection rating applies to both UVA and UVB wavelengths. This is the same spec across all ASWF films — it is not a differentiator between products, but it is a baseline that every film in the lineup meets.

Is Twilight 35 Right for Your Windows?

• Residential west/south-facing windows — ideal
• Home offices with screen glare — ideal
• Commercial storefronts — good; consider Daydream 15 for more privacy
• HOA-restricted neighborhoods — non-reflective, usually approved
• Dual-pane windows — safe; low absorptance prevents thermal stress
