The 7 best car heat shields to protect your upholstery

Which car heat shields are best for protecting your upholstery?

There’s no one trick to protecting your car’s interior, but sunlight is an oft-overlooked factor contributing to aging and discoloring. UV rays are responsible for the heat created in your car and much of the aging and discoloration on its upholstery. A common and effective solution for protecting your upholstery is getting a car heat shield that blocks the light out on those hot summer days.

What are car heat shields?

The term car heat shield can apply to a few different things. When talking about protecting your upholstery, the term usually applies to sun shades for a car’s window. However, light-blocking car heat shields, often called sun shades, are an effective way to prevent UV rays from harming your car seats and other interior upholstery. It’s also worth noting that sun shades or car heat shields cover the windshield and are only meant for use when the vehicle is in park — not while driving.

If you’re looking for a car heat shield for your engine, on the other hand, it may be hard to find something specifically made to protect the upholstery.
