- The sun is still striking the glass causing heat gain in the living space. It cannot be temporarily removed, it is like having permanent sunglasses on your windows.
- Voids the warranty on the majority of manufacturer’s window warranties.
- If not installed correctly the customer can see visible lines and bubbles. Even if tint or film is installed correctly – tends to bubble, peel, and crack after a few years of exposure.
- Window Film can cause thermal shock fracture when installed on insulated glass windows caused by an increase of heat and pressure between the panes of glass. Think of a really sunny day in winter. This is why window manufacturers void all warranties!
Reduction in Solar Heat Gain is another way of saying Solar Energy Rejected. Solar Energy Rejected is the ratio of the amount of total solar energy in the full solar wave length range (300-2100 nanometers)* that passes directly through a glazing system, to the amount of solar energy falling on that glazing system.
What this means is that on a normal summer’s day, about 600 watts of solar heat energy will fall on every square metre of our eastern and western windows for about four hours every day: the eastern windows in the morning and the western windows in the afternoon.
Solar energy does three things when it strikes a surface:
- Some is reflected: some of this reflected energy is what enables us to see the object.
- Some may be transmitted: this only occurs if the object is transparent or translucent.
- The balance is absorbed by the body as heat energy which raises the temperature of the body. Solar energy is not in itself hot, but it is called heat energy because of this phenomena.
Any sun affected window or any cold affected area, but they are a blind you have when you would really prefer not to have a blind at all, so they work best in a window with a view.
For an In'Flector Solar Blinds to reach its full potential it must be placed where it can take, and reflect the full force of the sun. Therefore Reflective Blinds are always installed in front of all other blinds and curtains. It is always the closest window furnishing to the glass.
Are In'Flector suitable (or even needed) for a west facing application where I already have double pane, low-E, argon-filled windows
Will they do any better for summer thermal insulation on a west facing window compared to regular blinds?
Yes. Regular blinds absorb the heat to some degree for both winter and summer application and the insulating factor is around an R2* unless you have the very heavy insulating curtains (velvet / wool) then the R factor goes up to around 8-9*. In'Flector Solar Blinds allow for an unobstructed view with an R factor of around 10 (windows are measured in U values, however people are not familiar with the system and we have recalculated the values into an R measurement).
- You can crease them
- You can crush them
- You can scratch them
- All of which you can do to most other blinds, but you can’t tear them
- While they are protecting you and your furniture, they are sacrificing themselves to the ravages of the sun
- These blinds are not designed to provide privacy at night when your lights are on
- They are not awnings, and cannot be installed successfully in outside applications
- In combination with screens they can produce a moray visual effect
