How much do window films cost?

DIY films: £20-50 per window. Professional installation: £50-150 per window depending on size and film type.

Do window films really reduce heat loss?

Quality low-E films reduce heat loss by 30-40%. Not as effective as new glazing but significant improvement over untreated single glazing.

Will films make rooms darker?

Minimal impact with modern films. Quality low-E films are nearly transparent while still providing thermal benefits.

How long do window films last?

Quality professionally-installed films last 15-20 years. Cheaper DIY films may need replacement sooner.

Can I apply films to double glazing?

Yes, but benefits are smaller. Films work best on single glazing or older double glazing units.

Quick Answer

Solar control films cost £50-150 per window versus £300-800 for replacement. Modern films reduce heat loss by 30-40%, block UV damage, and reduce glare. They're ideal for period properties, listed buildings, or when replacement isn't feasible. Professional installation ensures best results.

Understanding when window films make sense as an alternative to full window replacement.
