Insulation Window Film – Save on energy bills with Penjerex

Penjerex window film is manufactured by Nitto and is a heat insulation film with excellent levels of solar control as well as a neutral appearance.

A long lasting and durable film, Penjerex is a Low-E (low emissivity) film that delivers a host of benefits and can be purchased direct from The Window Film Company on a supply only or installed basis. The unique properties of the film make it a year round energy-saving window film, helping to maintain a moderate temperature during the heat of summer, whilst also preventing heat loss during the winter months. By providing such advanced levels of solar control and insulation, Penjerex can deliver energy efficiency savings as well as reducing harmful CO2 emissions.

An insulating window film

Penjerex (PX-7060S) film is manufactured specifically to deliver low levels of emissivity. This allows the film to deliver excellent thermal insulation, preventing the heat flow through windows by up to 35%. By preventing heat loss during the colder months of the year, insulation film will help keep energy costs lower by reducing the reliance on heating systems used to keep premises warm.  The neutral appearance of the film means that this is achieved without sacrificing the view or natural light.

Solar control as well as insulation

As well as industry leading insulation properties, Penjerex window film is also effective during the warmer months. The film rejects approximately 50% of solar heat, in turn ensuring a moderate and enjoyable internal temperature. By preventing the steady build-up of excess heat, the film not only makes for a more comfortable environment, but also reduces the strain on air conditioning, helping to deliver lower energy bills. By lowering the strain on both cooling and heating systems, low-emissivity (often referred to as Low-E) window film will also decrease C02 emissions, creating a smaller carbon footprint.

High transparency, low emissivity

Many Low-E window films are reflective in appearance, changing the look of glass and potentially blocking natural light. Penjerex PX-7060S delivers high performance alongside a high level of transparency, with 70% of natural light allowed to pass through the glass. The high VLT (visible light transmitted) figure means that the film provides a year round energy-saving solar control solution without sacrificing light, blocking the view or dramatically changing the appearance of glazing.

Benefits summary:

  • Excellent insulation properties. Heat flow out is reduced by up to 35%. 
  • High level solar control performance. 
  • Energy-efficiency window film. A cost-effective way of bringing down both cooling and heating costs.
  • Reduced CO2 emissions and decreased carbon footprint.
  • The blocking of 99% of the sun’s harmful UV rays.
  • High transparency delivers a neutral appearance and high levels of natural light transmission.
