Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

You should only use water to put out a fire in your fireplace in an emergency situation. Even then, it is better to use a fire extinguisher to put out a fire quickly. Make sure every room in your house that has a fireplace also has a fire extinguisher—and that everyone in your household knows how to use one.

A fireplace hearth is necessary in most areas per building codes, especially for gas and wood-burning fireplaces. Electric fireplaces may not require a hearth, so check local building codes or ask a pro for guidance if you’re leaning toward electric. A fireplace hearth can decrease the risk of flying embers creating a fire and burning your home down. That’s why fireproof material, like tile, is used for the hearth.

Pellet stoves burn compressed wood byproducts, making them very efficient and clean-burning. However, even efficient combustion still produces fine dust particles, which could have an effect on the health of vulnerable people in your household, such as infants and people with asthma. A wood stove pro can help determine whether the levels in your home are unsafe.
