Can You Get UV Rays Indoors?


Most of us know that when we’re outdoors, using sun protection to defend our bodies from the harmful effects of ultraviolet (UV) rays is essential. However, you may not know that UV rays can still be a risk even when you’re indoors via your windows. At Window Film Systems, we’re committed to spreading awareness about the dangers of UV damage and the steps you can take to protect yourself, your home, and the interior of your business.

Do UV Rays Pass Through Windows?

The short answer is yes! Regular clear glass allows around 75% of UV rays to pass through it, while reflective or tinted glass allows about 20-25%. Therefore, even when you’re indoors, you can be exposed to hazardous UV rays.

Types of Ultraviolet Light

Sunlight contains two main types of UV light: UVA and UVB. UVB rays are the type that causes sunburn and sun damage to furniture, and clear window glass is effective at filtering this kind of light (which is why you don’t get sunburnt indoors). UVA rays damage your skin invisibly and are the wavelength that causes skin cancer. Unfortunately, clear window glass is not effective in blocking UVA rays, exposing you to potentially dangerous sunlight even inside your home or business.

Does solar film protect against UVA rays?

Yes! Solar film has been expertly engineered to block 99% of harmful UV rays, so installing it on your windows is a fantastic way to protect yourself and your home.

How to Protect Yourself from UV Radiation Indoors

Installing UV Protective Solar Film

You can protect yourself and your interior furnishings by installing UV protective solar film from Window Film Systems. Solar film is an excellent way to give yourself an extra layer of sun protection while you’re indoors. With more people working from home than ever, it’s worthwhile to invest in the safety of your home and workspace.

Move Furniture Away From Windows

When at home or at your business, move furniture away from windows to prevent yourself from sitting close to windows where light directly shines into your home. While you may not get a visible sunburn from this light, UVA may still do invisible damage to your skin, and interior fabrics, causing fading and aging.

Wear Sunscreen Indoors

You can protect yourself from UV rays by wearing sunscreen indoors. Sunscreen should ideally be worn every day, regardless of season. Ensure that your sunscreen includes broad spectrum protection, meaning that it protects against both UVA and UVB rays, and has an SPF rating of at least 30 (per the Canadian Dermatology Association).

Prevent Damage to Your Interior Furnishings

Sunlight doesn’t just damage your skin; it can also cause permanent damage to your home’s interior, causing colours to fade, wood to crack, and fabrics to fray. This damage can lower the resale value of your home and destroy your furniture and possessions. Over time, it can cost you thousands of dollars in repairs or replacements.

Installing a solar film helps protect your investment and your belongings from the effects of UV damage, saving you time and money.
