The Patent-pending Low-E film coating on the Enerlogic window film directs both solar and radiant heat back to its source for substantial energy savings. Low-E film provides a perfect balance of energy efficiency, thermal comfort & cost savings of over 10% all year round. The Enerlogic ‘Low-E’ film is also fully compatible with high efficiency (low iridescence) lighting, avoiding the internal 'rainbow' effect from which other films can suffer.

Frequently Asked Questions

Is it expensive?

  • Solar Film - in a commercial context, it can pay for itself in as little as three years, based on energy savings on heating & cooling systems.
  • Safety Film - much less expensive than glass replacement, prevents damage to people, IT equipment/display stock, and prevents legal liabilities from injury caused by shattered glass.
  • Privacy Film - significantly less expensive than sandblasting, and can be removed/replaced.
  • UV Film - restoration from sun damage will be much more expensive; some objects are priceless.

What can window film do?

It can:

  • make glass shatter-proof
  • reflect the sun's heat
  • reduce winter heat loss
  • reduce glare
  • reduce fading and rotting of fabrics
  • provide frosted or one-way privacy
  • reduce energy costs and carbon emissions
  • provide a decorative effect

What is window film?

An off-shoot of interstellar travel over 30 years ago, it's essentially a polyester sheet, with an adhesive backing which bonds to glass. Sun-X has been applying window film since its inception, and even treating windows prior to this.

Will it have bubbles and creases?

No, not when professionally installed by Sun-X trained and highly experienced personnel. The clearer variety of films will even be invisible to the human eye.

Will it make the room dark of the windows mirrored?

Not necessarily. While dark reflective films will provide maximum heat reduction, there are now available some extremely effective 'clear' non-reflective solar films, making them ideal for listed buildings, or where high light levels are required.
