Do PVC Blinds Off-Gas? Understanding VOC Emissions

Polyvinyl chloride (PVC) is one of the most common materials used to make window blinds and shades. PVC is durable, easy to clean, and cost-effective. However, some homeowners wonder - do PVC blinds off-gas volatile organic compounds (VOCs) and is that a health concern?

What Causes PVC Blinds to Off-Gas VOCs?

PVC blinds can emit a range of VOCs, including phthalates and organotins used to soften the vinyl during manufacturing. The ingredients and production processes differ among blind brands and models.

In general:

New PVC blinds off-gas the most when first unwrapped due to accumulation of chemicals from storage and shipping.

Heat and sunlight exposure increases the rate of off-gassing from PVC blinds.

Off-gassing decreases over time as the materials release built-up VOCs.

So while all PVC blinds have the potential to outgas, brand new blinds or those in hot, sunny rooms will off-gas the most.

 

Potential Health Effects of Inhaling VOCs

VOCs themselves as well as specific ingredients like phthalates and organotins have been linked to:

Headaches, dizziness, nausea

Breathing problems

Developmental issues in children

Liver, kidney, endocrine damage

Reproductive health disorders

Cancer

Sensitive groups like children, pregnant women, the elderly and those with existing conditions may be most susceptible. However, all consumers should be aware of PVC blind off-gassing concerns.

 

Tips to Reduce VOC Exposure from PVC Blinds

While no guidelines exist for safe exposure levels, you can take precautions to minimize risks:

Allow new blinds to air out for several days before installation.

Periodically wash blinds with mild, fragrance-free cleaners.

Increase ventilation via open windows, fans, and air purifiers.

Keep blinds closed whenever possible to reduce heat/sunlight exposure.

Consider less toxic blind options like wood, bamboo, metal, and other polymers.

Every small step to reduce VOC accumulation can benefit your indoor air quality.

 

Safer PVC-Free Blind Alternatives

If you remain concerned about potential health issues from PVC blind off-gassing, switching to PVC-free window treatments is your best bet.

Eco-friendly blind materials like bamboo, wood, aluminum, and polyester blends give the beauty of PVC without the risky chemical exposures. Brands like Timber and Bamboo Supply Co. offer stunning blind options to suit any decor.

Check labels and descriptions carefully to verify blinds do not contain PVC or vinyl. This gives you peace of mind about the air you and your family breathe every day.
