Glass Door Installation in San Antonio, TX

Mainly when the fireplace is idle: closed doors cut the draft that pulls heated room air up an open flue. During an active wood fire most heat still goes up the chimney, and doors are typically kept open while burning. They also block embers and keep pets and kids out of the firebox.

A barrier screen is a safety mesh that prevents contact burns on hot glass and is required on many newer gas units. Traditional bi-fold glass doors are mostly for masonry wood fireplaces. Which you need depends on whether the unit is gas or wood and what the manufacturer specifies — don't put non-rated doors on a gas insert.

Some masonry-mount doors are homeowner-installable, but correct sizing to the firebox opening and a secure mount matter for both safety and looks. Factory-built fireplaces usually require the manufacturer's own door, not a universal masonry unit — using the wrong one can void the listing.
