3M Prestige PR70 Solar Control Window Film Case Study

Case Study – 3M Prestige PR70 Window film.

The latest technology in the 3M Sun Control film range – A ‘clear’ heat, glare and fade control solution metallic films can’t match.

A home owner in Sydney’s lower North Shore approached PARAGON with an increasing fade problem. It is often seen in residential and commercial buildings with extreme exposure to the sun.


The recently purchased home had timber floors and large floor to ceiling glass in almost every room in the house. This is great for letting natural light in during the day and capitalising on the harbour views, however the down side to this type of situation is the damaging effects of fading caused by heat radiating through the glass, visible light transmission and ultra violet rays. Replacing furnishings frequently is a costly exercise. Keeping this amount of heat out is another expense as they are forced to use the air conditioner more frequently at high performance.



PARAGON’s 3M Prestige PR70 Solar Control Window film is a superior solution to reducing heat, glare, ultraviolet rays, prevent fading and reduce energy costs, in one film, without looking like there is a film on the glass. This way problematic areas that require the film verses other areas that don’t, still remain uniform from the inside and outside of the building. Traditional window films can be either dark dyed films which can fade & turn purple or highly reflective mirrored films that change the external appearance of the building giving a ‘patchwork’ effect if some areas are tinted and other areas not.


3M Prestige PR70 film was the obvious choice as it uses innovative Multi-layer Optical Film technology, to provide a window film product with a clear appearance and a host of advantages. Enhanced on angle performance, high IR reduction, superior clarity, along with no chance of corrosion and no signal interference are among the benefits. 3M Prestige PR70 film gives low reflectivity along with an optimized balance of performance and natural light. While essentially not changing the external appearance of the building, it reduces 97% of Infrared Heat which accounts for 50% of all heat, 23% of glare and 99.98% of UV rays.

The 3M Prestige Series marks a significant technological advancement in how window films can enhance buildings and homes. Residential and commercial property owners now have a high performance clear window film that combines all the benefits of heavily-tinted or reflective films, without the inherent drawbacks of darkened rooms or mirrored windows. Prestige films actually have 1% higher reflectivity than the glass they cover, so the appearance of your building is virtually unchanged.


PARAGON performed the installation of approximately 200 square meters of film within two working days in a straight-forward and trouble free way, which resulted in no disruption to the owners. The results were immediately noticeable. With the air conditioning running at a lower level, the savings in energy costs in summer would be genuinely substantial. The owners could now preserve and protect their new and existing artworks, timber floors and enjoy their improved clarity, overlooking the harbour and without the need to pull blinds to block heat.
