We’ve chosen fiberglass doors for our Foothill Series because they are low maintenance, energy efficient, and - most importantly - durable. They resist dents, scratches and are impervious to rot and rust. In addition, this type of door never bows or warps from exposure to weather. When properly installed, fiberglass doors offer superior security. Your entry door is only as secure as its frame, but composite door frames have twice the screw-holding power of wood. Additionally, fiberglass doesn't deteriorate over time as opposed to doors manufactured from steel or wood.
