In the UAE, sun shades should always be placed inside the vehicle, with the reflective side facing outwards towards the windshield. This placement is crucial for their primary function of reducing the cabin temperature by blocking and reflecting solar radiation, which can exceed 1200 W/m² on a typical Dubai summer day. RTA Dubai's summer vehicle checks often advise using internal sun protection to prevent rapid interior deterioration. According to insights shared by Ab Dhabi Mobility, proper use of sun shades can lower the dashboard surface temperature by up to 30°C, significantly reducing the strain on the air conditioning system when you re-enter the vehicle. An internal placement also protects the shade itself from the harsh elements—whether it's abrasive sand-laden winds in the desert or the sheer force of a shamal wind—and prevents it from scratching the exterior glass or being stolen. For a standard GCC-spec Toyota Land Cruiser or Nissan Patrol, a good quality internal shade can make the first few minutes of driving after parking under the sun much more tolerable and protect sensitive dashboard electronics and leather from cracking.
- Effectiveness: Can lower dashboard temperature by up to 30°C.
- Protection: Shields interior plastics and leather from UV degradation.
- Safety: Prevents shade from becoming a projectile or getting damaged externally.
