What is window film and how does it work?

Window film is a thin layer of polyester or vinyl that’s applied directly to glass. It reduces heat, glare, and UV exposure while improving privacy. Some films reflect sunlight, while others absorb it to regulate indoor temperature without changing how the glass looks.

What's the difference with privacy and frosted film?

Privacy film limits visibility through glass without blocking light, making it ideal for offices, bathrooms, and street-facing windows. Frosted film gives glass a soft, translucent appearance, similar to etched glass, offering full privacy while still allowing daylight in.

Can window film reduce heat in my home or office?

Yes. Solar control films can reduce heat by up to 80%, lowering your need for air conditioning and helping to maintain a comfortable temperature year-round.

Will window film make my room too dark?

No. Modern films are designed to balance heat reduction with natural light. You can choose from clear, tinted, or reflective finishes depending on how much visibility and light you want to keep.

How much does window film installation cost?

Costs vary depending on film type and window size, but most installations range from £30–£80 per m². It’s significantly cheaper than replacing glass and delivers energy savings over time.

How long does window film last?

Quality films from brands like 3M can last 10–15 years when properly installed. They’re also removable if you ever want to update the look or switch to a different style.

Can I install window film myself?

You can, but professional installation guarantees a flawless, bubble-free finish. Experts like Velfi Interiors use precise tools and techniques to ensure long-term adhesion and a clean, polished result.

Does window film provide UV protection?

Absolutely. Most films block up to 99% of harmful UV rays, helping to protect furniture, flooring, and artwork from fading and sun damage.

Is window film energy efficient?

Yes — it helps regulate temperature by keeping heat out in summer and retaining warmth in winter. This reduces the load on your HVAC system and can cut your energy bills by up to 30%.

Where can window film be used?

It’s ideal for homes, offices, schools, retail spaces, and healthcare environments. Common uses include meeting rooms, reception areas, and bathrooms — anywhere you need more privacy, style, or solar control.
