Low-e window film – insulation – silver reflective – internal install

Low-E window film is ideal for improving energy efficiency in a variety of settings. It’s especially effective on:

• Single-glazed windows in homes, offices, and conservatories
• Rooflights and skylights where insulation is typically poor
• Older buildings where upgrading to double glazing isn't feasible
• Conservatory roofs to help maintain a stable temperature year-round

If Low-E window film isn’t the right fit, consider:

• High reflective silver for similar heat, glare & UV rejection (without reducing winter heat loss) and daytime privacy at a lower cost.
• Coolclear solar deluxe if your primary goal is protecting furnishings and
  interiors from sun damage
• Silver frost for similar heat, glare and UV rejection without reducing winter heat loss. Has an external mirrored appearance day and night but you can't see out either.
• Coolkote for conservatory polycarbonate roofs where glare and heat are extreme

Check out our installation guides for help installing window film in different situations.  A good starting point is.

• Cut the film slightly larger than what you need.
• Clean the glass thoroughly.
• Spray a slip solution made of water and baby shampoo on the glass.
• Remove the backing liner and spray the same solution on the exposed adhesive.
• Put the film on the glass and float it into place.
• Cut the film tight to the frame.
• Use a dedicated hard squeegee to remove the water from underneath the film.
