Fiberglass Series


In addition to warping, shrinking, cracking and rotting, there are other problems associated with wood. The cost and availability of quality wood today is another matter making it prohibitive; what hardwood there is comes at a high premium and much of the time it is from “second growth”, making it of lesser quality than older wood.

Also the oil-based stains and sealers of yesteryear, which were far more effective but harmful to the environment but little, are rarely adequate for the longevity of the door. Hence, a door needs to be re-stained and re-sealed every 3-5 years.

Fiberglass technology has now evolved to the point where it literally has the appearance of wood; one has to knock on it to tell the difference. The inherent problems of wood are now a thing of the past and it requires virtually no maintenance. It is also far less expensive.

Because a fiberglass door does not absorb moisture as wood does, it provides superior insulation for the home allowing substantial energy savings. Another insulation feature to the Martindale door is a feature whereby the deadbolt is thrown; ramps push outward sealing the door to the weather strip.

Contractors and installers also appreciate these doors, as installation is simpler. This especially becomes important with larger doors.

Because of their durability and longevity, there are few to no callbacks once the doors are installed.

Fiberglass doors themselves have been around for about 15 years.

The most recent development which makes them very attractive for homeowners is the fact that fiberglass frames are now manufactured as an exact match to the doors; fiberglass doors no longer have to be hung in wood frames. There are also a much wider variety of designs available and they now can be fitted with sidelites, transoms and even leaded glass panels as wooden doors can.

Fiberglass systems have also eliminated the need for double-doors for expansive entries. Wood, because it can expand, contract and especially warp, would not support a very wide single door. Since these systems are so stable, a 42-inch-wide 8-foothigh with true divided sidelights give the grand entrance customers are looking for without the requirement of a double-door.

And of course another benefit of fiberglass doors is to the environment: they help save our forests.

But in the final analysis, it’s the appearance that’s going to make or break the choice of a front door and the new fiberglass doors have obviously made the grade.

Fiberglass Opens the Door to Cost-Effective Entry Options

Pricy wooden door systems are now being replaced by less expensive and sturdier fiberglass-and you can hardly tell the difference.

While wooden front-entry doors have been staple for hundreds of years, they certainly have had their problems. They require regular maintenance, especially if there are any extremes of heat, cold or precipitation. Temperature variations cause them to swell and shrink, creating problems with normal opening and closing. They’re not well-insulated. Last but not least, they’re not cheap. In the 21st century, however, there is finally a cost-effective and durable alternative – fiberglass door system.

“People want the beauty of a wooden door” says Len Martindale, owner and general manager of Martindale Window and Door, provider of a new line of fiberglass systems. “They can now get that in a fiberglass door system which provides real insulation, does not expand or contract from the heat and cold, requires no maintenance and costs half to two-thirds the price of a wooden door.” Appearance wise, these new systems are also nearly indistinguishable from their wooden counterparts-a person literally has to walk up and feel it to tell the difference. These new systems will accept any stain of any colour, light, dark or medium and in fact are easier to stain than wood.

Fiberglass door systems are also more durable, and don’t chip, dent or scratch as easily as wooden doors. Due to their fiberglass composition, they are also not susceptible to moisture invasion. Depending on conditions, a wooden door may need to be replaced in as little as 5 years, whereas a fiberglass systems lasts 40 years or longer.

As to security, there is almost no comparison. The standard wooden door normally has a single lock system on the center edge, whereas the fiberglass door systems secure in 3 different places: at the top, centre and the bottom of the door as well.

When the door is locked, a roller bearing also presses the door tighter to the weather stripping at the top and bottom, sealing it. This is an additional weather-proofing feature. Traditional wooden doors are fitted tightly to the weather stripping, it will be hard to operate in various temperature extremes or in severe dampness.

Hence, air enters through gaps in the top and bottom of the door. The fiberglass models end this problem.

Another improvement over older fiberglass models is the addition of a fiberglass frame. Previously, a fiberglass door would have to be hung in a wooden frame, but with the new systems, frames can be matched to doors stylistically and can be stained to match the door. And like the door, the frame is maintenance-free.

As with wooden doors, these doors are available with a wide variety and arrangement of window panels. Sidelights, transoms and even leaded glass panels are available.

Due to the price difference, higher-end doors with such added elements such as window panels are now more in reach for the average consumer, that typically might only appear on more affluent residences. “One woman who was building a home recently fell in love with a wide fiberglass door system,” Martindale relates. “When she saw the price, she had to have it, and bought it. The home she was building was only a $250,000 home and normally a door like that would be seen on a house $500,000 and up. So finer door systems are now within reach for everyone.”

Along with the lower price, of course comes the added advantage of the much-longer lifespan and durability of the door.

Fiberglass systems have also eliminated the need for doubledoors for expansive entries. Wood, because it can expand, contract and especially warp, would not support a very wide single door. Since these systems are so stable, a 42-inchwide 8 foot high with true divided side lights give the grand entrance these customers are looking for.

Many stock designs are available, but systems can also be fullycustomized to specifications. As to ease of installation, the new fiberglass systems come pre-hung, so they are as easy or easier to install than their wooden counterparts.

Fiberglass has truly opened the door tolonger-lasting and more costeffective entryway systems. Wood doors need to be re-stained and re-sealed every 3-5 years whereas a Fiberglass door requires no maintenance and is far less expensive.

Fiberglass doors do not absorb moisture as wood does therefore providing superior insulation for the home and allowing substantial energy savings.

Fiberglass doors have been around for about 15 years and now have a wider variety of designs available to the consumer. They can be fitted with sidelights, transoms and even leaded glass panels.

The tough resilient fiberglass frame affords security similar to steel but will not corrode. The doors will not bow, warp, crack, splinter, scratch, dent or rust as with wood or steel.

Fiberglass doors are far more durable than wood – with little to no maintenance it can last the life of the home as opposed to an average of 5 years a wooden door can survive until it needs a complete overhaul.

Fiberglass doors are far more secure than the standard wooden door.

Martindale Frames

Our Fiberglass frames will match fiberglass doors to complete a total elegant rich wood look without any of the problems that can occur with wood frames. Composite Fiberglass frame matches the doors.

Fiberglass Frames

An innovative new alternative to traditional wood door frames. After extensive research and development, we have formulated a poly-fiber door frame system that combines all the strength and convenience of wood with enhanced properties that make it moisture, rot and insect resistant, with the added beauty of wood. This unique formulation means that they will not absorb moisture and will never warp, splinter, or rot. And the system can be machined the same way as traditional wood frames with no added hassles. These frames guarantee a long-lasting, rot-free entryway that will maintain its integrity for a lifetime.

Wood Frames

Traditional wood door frames are made of Finger Joint Pine. They are designed to enhance structural properties, reduce warping and ensure years of trouble-free performance.

Aluminum Frames

Designed with the same Finger Joint Pine Frames. Cladded with prefinished heavy extruded aluminum. These frames will ensure a maintenance-free durable exterior finish and will allow any of our vinyl window products to be mulled as sidelites or transoms.
