Window Film vs Blinds: The Best Option for Tricky Windows
If you’ve got a roof lantern or glazed extension, you’ll know how gorgeous they look – but also how easily the sun can turn your space into a sweltering greenhouse. ☀️ Two popular ways to beat the heat and glare? Window film and roof lantern blinds.
But which one’s the right fit for your home – and your roof?
Let’s compare both solutions in detail, including when window film might actually be the better option, and when blinds give you the most comfort and control.
What Is Window Film?
Window film is a thin, adhesive sheet applied directly to the inside of your roof lantern glass. It’s designed to reduce UV rays, glare, and solar heat gain, and comes in a variety of finishes from tinted to reflective.
Best for Awkward Roof Lanterns
Window film really shines when you’ve got:
- Very large roof lanterns (over 3m wide x 5.8m long)
- Odd shapes or curved glazing
- Crossbars, lighting fixtures or beams that block blind installation
In these cases, blinds may simply not be a practical option – and film becomes your best bet for improving comfort.
Keep in Mind:
- Must be professionally fitted to avoid bubbles and peeling.
- Not removable or adjustable once applied.
- Privacy films don’t work at night, when lights are on indoors.
What Are Roof Lantern Blinds?
Roof lantern blinds are made-to-measure systems that sit neatly inside your glazed roof, offering adjustable light and heat control. Available in insulating fabrics and smart styles like:
Why They're So Popular:
- Self-fit friendly – no need to pay for professional installation
- Great thermal performance – keeps warmth in during winter and heat out in summer
- Adjustable light control – open, partial, or closed
- Available in manual or electric styles, depending on your needs
Blinds are especially ideal when you have a standard rectangular or square roof lantern with clear mounting space around the perimeter.
Window Film vs Roof Lantern Blinds: Which Works Where?
Here’s how they stack up, feature by feature:
| Feature | Window Film | Roof Lantern Blinds |
|---|---|---|
| Best For | Awkward, oversized or obstructed roof lanterns | Standard-shaped roof lanterns with clear edges |
| Heat Reduction | Good (reflects solar heat) | Excellent (especially with insulated fabrics) |
| Winter Insulation | Poor | Excellent (traps warm air in colder months) |
| Glare Reduction | Good – but fixed | Adjustable on demand |
| Privacy (Day/Night) | Daytime only (reverses at night) | Full privacy any time of day |
| Light Control | Fixed – no adjustment | Fully adjustable |
| Appearance | Minimalist, near-invisible look | Softens ceiling, decorative options available |
| Operation | No operation required | Manual or motorised options |
| Cost | Lower initial cost | Higher upfront, but long-term value |
| Maintenance | Very low | Light dusting or vacuuming now and then |
| Custom Fit | One-size application, trimmed in place | Made to measure for exact roof lantern size |
| Installation | Needs professional fitting | Self-fit in most cases |
| Longevity | Can degrade, bubble, or discolour over time | Long-lasting with quality fabrics and components |

- Your roof lantern is oversized, irregularly shaped, or has obstructions like crossbeams or lighting
