Modern fiberglass garage doors are a good alternative to pricier wood garage doors

The modern premium fiberglass garage doors are more than just fiberglass. Actually they are composite doors, combining a steel core behind a fiberglass skin.

Many of them have also polyurethane insulated base sections, in order to achieve higher insulation levels.

As to modern wooden garage doors, their major selling point is in their look. Wooden garage doors can also be a reasonable choice from an environmental and energy-efficiency standpoint, but they can be expensive and a poor choice for strength or from a maintenance perspective.

Prices of fiberglass vs. Wooden garage doors

Fiberglass garage doors are more expensive than steel, but less expensive than wood garage doors.

You can find many 16-by-7-foot fiberglass doors at prices about $1,800 - $2,000 installed, while standard hardwood doors start at prices ranging from $2,500 to $3,000 or more.

Some low-grade wood garage doors are inexpensive but prone to warping and cracking problems. Premium wood garage doors are a lot more expensive than steel, vinyl, fiberglass and most other types of garage doors.

Besides, wood serves as a natural insulator against sound, heat and cold.

On the other hand, modern wood doors can be highly engineered products, able to overcome part of their traditional disadvantages – new premium doors offer extra-strength, durability and insulation.

But overall there are other types garage doors with obvious advantages over wooden garage doors: fiberglass doors have the advantages mentioned earlier.

Wood vs Fiberglass garage door Insulation

New fiberglass-composite garage doors can be high thermal insulated doors. They can be engineered to provide high R-values. But be aware. The values advertised for fiberglass and other types of garage doors fall short of their actual R-values. The actual R-values are often 1/2 or 1/3 of the advertised.

In this perspective they do not differ significantly from hardwood garage doors. The difference is often in the quality of the instalation or on features such as the seals of the doors.

Premium wood garage doors

Some stain option for a specific model of wood garage door, from ClopayNew wood garage doors, even premium units, are typically rail and stile, that is, their frames are made from popular wood species (cedar, redwood, hemlock...) but their panels are made from engineered woods (MDO plywood or MDF…) with a thick hardwood interior backer, glued to the frame.

composite doors

Wood composite garage doors are made of engineered wood fibers: materials like MDF (Medium Density Fiberboard) and MDO (Medium Density Overlay).

These materials have the look and texture of wood and are less prone to splitting and trimming. But they have some of the disadvantages of wood, namely high-maintenance requirements...

Factory finish or unfinished wood garage doors

Some decades ago, all wood garage doors were finished on site - but that’s not the case anymore. That option is still available but manufacturers are also offering a factory-finish paint option, that is, you can buy your door primed, painted and ready to be installed.

You just have to choose the right paint or stain color and the sealing and finish coats...

Flush style wood doors

Garage door flush style: wood doors with a foam coreSome manufacturers are also offering many styles of flush style wood garage doors, with or without windows and decorative elements.
