Product Overview

About Natural 20 Window Film - for internal application

If your room feels more like a spotlight stage than a comfortable living space, Natural 20 helps you turn the brightness down — without creating a mirrored appearance. As the darkest option in the Natural tint range, it’s designed for spaces where light control really matters. You’ll notice less glare, less heat build-up, and a deeper smoke finish that gives your glass a clean, modern look.

What this means for you

  • Solar heat reduction – reduces the heat entering through your glass, keeping your space cooler and more comfortable.
  • Glare control – cuts down harsh sunlight so you can enjoy clearer screens and easier viewing.
  • UV protection – blocks up to 99% of harmful UV rays, helping protect both you and your interiors.
  • Dark natural tint – the deepest shade in the natural range, offering a richer look with stronger shading.
  • Interior protection – helps slow fading caused by sun exposure, keeping furnishings and displays looking their best for longer.

Designed for brighter, tougher spaces

Natural 20 is ideal if you’re tired of excessive sunlight throughout the day. Compared to lighter options, it significantly reduces visible light. You still keep your outward view — just with a darker, calmer tone that makes the space easier to live and work in.

Subtle daytime privacy

The deeper smoke tint can also help reduce visibility into your space in brighter outdoor conditions. It’s not a mirrored one-way film, but it does offer a degree of daytime privacy while maintaining a natural look on the glass.

Built for everyday life

With a durable, scratch-resistant coating, Natural 20 is designed to maintain its clarity and appearance over time. This makes it suitable for both homes and commercial environments. After all, comfort should last longer than one sunny season.
