In general, windows are made from wood, aluminum, steel, vinyl or fiberglass. Read below to find out the benefits and disadvantages of each material.
 
• Wood: A common choice for windows, wood is durable and prevents the cold and condensation from coming inside. Make sure you’ve treated it, otherwise it may warp and rot over time.

• Clad wood: This type of material is basically wood covered in an exterior jacket made of aluminum of vinyl which eases maintenance issues like preventing rust and rot.
 
• Vinyl: Resistant to heat loss and condensation, vinyl windows are inexpensive but may become distorted if exposed to extreme heat or cold.

• Steel: One of the pricier options, steel windows are attractive, easy to maintain and long lasting.

• Aluminum: Lightweight and durable, aluminum windows are insulated with vinyl and foam to help reduce heat loss and condensation. Moist, salty air may deteriorate aluminum windows if they are not properly treated.
