The simple answer is no.
When it comes to blocking harmful UV rays, not all windows are equal. Glass blocks UVA and UVB radiation differently. 🔽
All glass used in house, office and car windows completely blocks UVB from passing through. ✅
But only laminated glass can completely block UVA.
UVA can pass through other glass used in car, house and office windows and cause skin damage, increasing the risk of cancer and collagen breakdown, leading to premature ageing. ❌
A car’s front windscreen lets in lots of sunshine and light. Generally, it blocks 98% of UVA radiation because it is made of two layers of laminated glass.
However, the side and rear car windows are usually made of tempered glass, which doesn’t completely block UVA. ☀️
Repeated UVA radiation exposure through car side windows might go unnoticed, but it can affect our skin. 🙎♀️🙎♂️
For instance, Australian studies report more skin damage and more skin cancer on the right side of the body, which is also the side closest to the window when we drive. 🚗
Our favourite ways to protect against the sun while driving is by:
☀️ Wearing Sunscreen
☀️ Wearing Driving Gloves & Arm Sleeves (A good brand we like is 'Solbari')
