Fiberglass Entry door systems
Rated Fiberglass foam filled insulated steel or fiberglass door systems offer the beauty of custom wood grain or smooth design finished in a variety of stains and shade.
Fiberglass, vinyl or steel doors may be purchased in standard or custom sizes limited only by a manufactures ability to produce.
Depending on your home’s requirement, door systems may be extended with added side lite panels or even overhead transom panel.

Entry door Curb appeal does reflect the interiors content!
Proven fact: “you can always tell how nice the interior of a home is by it’s entry way”! Realtors have preached this for years as their professional office tour dictates.


So What type of Door should I select? Steel? Fiberglass? Wood? How do I know What’s Best?

Confused??? Toooo many option. Lets narrow it down to type of door first of all.

Of the three basic types of doors listed above, how will you decide what is right for you? Or do you select what is right for your Home? Gatcha right….here’s the difference.

Entry door locations being front, side, rear doesn’t matter…receive the elements and sun exposure. So with this is mind determine the best type of door for each entry location.

If you front door has morning and all afternoon full sun exposure then you may want to reconsider that pretty fiberglass door and consider steel.

Here’s why…Fiberglass doors are constructed using a simple slimline wood frame surrounded, front and back, with a fiberglass shell panel….very flimsy on it’s own. Once assembled the unit is injected with rated insulated foam. This foam penetrate all void throughout the panel cavities providing a solid fill of the door panel or door slab for short.

The foam provides an excellent r-rating for insulation and no storm door is required to increase it’s efficiency.

The problem here is that as soon as the sun hits this panel it will expand and contract, as all building materials, in it closed position you end up with a banana door. The door is closed and the latch is locked so why do I see daylight at the top and bottom of the door at the strike jam location (lock side)?

The answer, Only when the sun is on it. Yes the door will bow. Even in the winter time allowing cold air to infiltrate you home after spending your hard earned money on this pretty fiberglass entry door.
The good news is, only during the day time with direct sun exposure. Change you thought here to a Steel Door Finished by the manufacturer.

Also forget about a storm door over fiberglass as this typically voids the manufacturer’s warranty…it actually over expands the door slab panel to eventually split…..after all, you can only inflate a balloon so far before it pops…right.

Let’s not even talk about the hot hot summer sun tearing up the gel stain top finish on this thing.

Fiberglass door unit are in fact beautiful. Extremely attractive and I certainly recommend for any home to enhace the entry way beauty….BUT NOT IN FULL SUN LOCATIONS. 

// Wood Doors have excellent superior finishes to them. They are in fact custom manufactured.They enhance the beauty of ever entry way….however do require maintenance. Not at first, but in time as the elements, sun, salt rain beat away at the finish. Now finishes can be restored..that is as long as you are aware of the need. Wood can chip, crack I have experience sap blistering from a finished wood door. Not steering you away here…just apply the same rules as fiberglass and you’ll be fine.

// Usually with wood panels the areas of concern are dents, key scratches and general abuse….to confirm just check out you door you are replacing…right? Not catch that scratch or blemished can eventually lead to door panel rot or decay.

Which brings us to Steel. The same beauty and elegance can be brought to your doorstep through steel. Basically the same stylish designs as fiberglass. Foam fill for high efficiency, like fiberglass however suitable for any location. no swelling, bowing or over expanding bar none the best type in my opinion for any exterior location. The only condition….have the manufacture finish the door in you selected color choice and allow their warranty to kick in should there be any trouble with the finish holding up.

The key to remember here is that anything man manufactures and places min direct sun all day will eventually fail. a Proven fact. Shop well.

Ten steps to a properly installed prehung door system

Prehung door systems are door panels assembled to a manufacturers frame and is designed exclusively for that door panel. Many contractors are still under the belief that because a unit is prehung it can be placed into any opening and immediately fastened to the building. All units must be level plumb and square. This can only be established by the following
 installation guide lines and missing one step will cause incorrect operation as intended by the manufacturer.

As a prior warranty rep inspecting doors installations throughout the tri-state area, I have found that 8 out of 10 installed units failed as a result of installation. Poor performance, damaged parts from incorrect install techniques, out of level units, arc thresholds, binding panels you name it. Follow the steps below or make sure the installer follows to provide a proper installation.

When the old unit is removed
 Check left and right rough carpentry for left and right level (rack) and from front to rear level (street to yard direction) this will provide you with upfront knowledge as to how or where you may need to position the new unit. If you know what framing conditions exist before the door is set for install you will realize where potential mis-alignment with walls comes from.
  1. Place a level on the entry floor threshold to determine where the unit frame may have to be raised or leveled. This is the biggest area of concern when installing, if you place the unit on an out of level base the remaining steps ill not provide proper operation. The job will be shot. Very rarely is a threshold 100% level as this is rough carpentry.
  2. Before setting the unit make sure there is proper flashing which is a continuous metal wrap from under the door to “L” bend down in front which will be hidden behind the kick plate below the new unit threshold. Once installed provide 100% silicone to the top to insure new unit is placed in a full seal to prevent weather and wind from blowing under the door frame.
  3. Place the unit and provide left and right wood block shims at the top head jam locations to temporarily wedge and hold the unit in place.
  4. begin to level the unit, check the threshold and add shimming where necessary, under vertical jam stock only, to raise that part of the unit only to provide level set.
  5. Using your level place on interior or exterior of jam at left and right side (street to interior of home) to adjust to plumb and level.
  6. Using your level place on the jam frame left and right side (in line with the wall) to determine if the unit is level. This is where a racked unit can fail. A racked unit is simply leaning to the left or right of plumb. If you have ever seen a door that rubs at the top frame or one part of the strike jam hits the door panel when closing or even the sweep is being pinched too tight when closing, then this may be caused by a racked unit. Check other doors throughout your home.
  7. Once plumb level and square properly shim the frame where the manufacturer specifies. This is important as incorrect shimming will void warranties. Typically shimming locations are 3 area left side 3 area right. Hinge side is directly behind each hing which will align and close gaps where the door slab closes. Make sure these reveals left, right, and top are uniform and consistent. Over shimming will cause panel hit or binding, under shimming will cause improper operation, air leakage, system failure with component damage. Please read manufacturers direction in full.
  8. Install set screws provided by manufacturer in the manner described by the manufacturer. Only set the unit as described by it’s manufacturer. There is a reason for this. There are expansion and contraction rules at play here. Also warranties may be void if the unit is not properly secured. Never install a door unit by the exterior brick mold trim only. I have personally failed hundreds of installs regarding this poor method. The unit frame will eventually separate causing fail and leaning frames.
  9. Insulate the left, right and top head jam locations (not spray foam) using fiberglass insulation. Spray foam expansion may over pack the void between the newly installed jam and dwelling framing.
  10. Install casing trim to interior along with door knob hardware and your basically finished.
Special notes: each step of the way test drive the unit by gently opening and closing the door, this will provide you with the knowledge as to where you may have a problem.
