What is EVglass?
EVglass is a sealed and removeable polycarbonate panel that is attached to the bottom of the cars glass roof to create a double pane window. The insulating effect works even better than it does in our homes due to the fast airflow over the glass. When driving, the temperature difference between uninsulated glass and EVglass protected areas in very cold conditions is typically 20°C.
What are the benefits of double pane glass?
-
A more comfortable cabin
- Efficient summer cooling
- Efficient cabin heating
- Reduced cabin noise
Our glass roofs get very cold during the winter and very hot during the summer, the thermal radiant effect reduces cabin comfort. The EVglass keeps the cabin roof at a comfortable temperature.
Electric vehicles typically lose 20% - 40% of their range during the winter, one of the main reasons is cabin heating. Our EVglass reduces the heat loss through the glass roof by 75% which dramatically reduces the energy required to heat the cabin.
The EVglass panel is easy to install and can be used year round to reduce AC use during the summer.
Precise testing using Teslas diagnostic and recording data showed a 24% reduction in range loss at -10°C / 14°F, and the colder it is outside the greater the reduction in range loss.
How do they look?
The sunlight and warmth through our glass roofs is appreciated the most during the winter, the clear insulating panels are a no compromise option for efficiently warming the cabin.
The EVglass panels are made from a high quality polycarbonate. A seal on the panels creates an insulating air gap similar to the double pane windows in your home, the panel adds additional insulation but the sealed air gap creates the majority of the insulating effect.
A grey closed-cell polyethylene foam trim material is provided in the kit which may be attached around the edge of the panels if desired.
How are the panels attached?
The EVglass panel is held in place using a nano tape seal which is attached around the outer edge of the glass. Nano tape uses the same molecular adhesion force as geckos' feet and like a magnet is not effected by heat or cold and leaves no residue on the surface when removed. It is also very strong.
The nano tape is pre-installed on the EVglass and includes a clear plastic release liner which is removed as the EVglass panel is installed.
