Frequently Asked Questions
Is steel or fiberglass more secure?
Steel is harder to break through. However, fiberglass with proper locks is very secure. For maximum security, choose 20-gauge steel or reinforced fiberglass.
Which door insulates better?
Fiberglass insulates 5-6x better than steel and won't transfer cold like metal. In extreme climates, fiberglass saves $50-100/year in energy.
Do steel doors rust?
They can, especially in coastal or humid areas. Quality steel doors have rust-resistant coatings. Plan to repaint every 2-3 years in harsh environments.
Can fiberglass look like wood?
Yes, premium fiberglass convincingly mimics wood grain. From 10 feet away, most people can't tell the difference. Staining options enhance the effect.
Which lasts longer?
Fiberglass typically lasts 30-50 years; steel 20-30 years. Climate matters: fiberglass excels in humidity/coast, steel in temperate areas.
