How to stop an itch from fiberglass insulation

Updated February 21, 2017

Fibreglass insulation can be tricky to work with. It is made up of tiny particles that can get into your skin pores and cause redness, irritation and itching. You also run the risk of inhaling these particles and causing damage to your respiratory system. If you must work with fibreglass, take some precautionary measures before you begin your work. After you're finished working, clean any fibreglass off yourself immediately to prevent further itching.

Preventing fibreglass itch can be easier than coping with it. Before working with fibreglass insulation, coat your exposed skin with plenty of talcum powder or cornstarch. Some hardware stores may also carry a product that applies a thin layer of latex to your skin. This prevents fibreglass from getting into your skin.

Cover as much of your skin as you can with protective clothing while working with fibreglass. Wear thick gloves, long sleeves and trousers. If possible, wear a hood on your head. Wearing a face mask is also important. This will prevent you from breathing in fibreglass fibres.

Refrain from scratching your fibreglass itch. Scratching or rubbing will force the fibreglass deeper into your skin, rather than getting it out.

Take a cold shower immediately after working with fibreglass. The cold water will help keep your pores closed so that the fibres don't get deeper into your skin. It will also wash off the larger pieces of fibreglass.

Take a hot shower or bath following your cold shower. The warm water will open your pores, allowing any remaining fibreglass to work its way out.

Apply body lotion or baby oil to your skin after your shower. This will soothe your irritated skin and help to stop the itching.


Launder your work clothes separately from any other laundry to prevent fibreglass from attaching to the rest of your wardrobe.
