Plastpro Doors and Door Frames

     Plastpro brand fiberglass doors is the leader in fiberglass exterior entry doors that will not rot over time. They are the strongest door on the market due to the internal structure of the door slab. This is the area a consumer cannot see but it is this structure that sets Plastpro apart from all other fiberglass door manufacturers.

Also, these doors have fiberglass composite on ALL 6 sides of the door slab including the top and bottom edges. This ensures there is no exposed wood susceptible to eventual decay.  The most common competitor on the market has wood edges on the vertical edges and uses composite only on the top and bottom edges of the door slab.

    The Plastpro doors fiberglass door frame wraps the entire door frame, not just 6-8 inches from the bottom.  This ensures a strong not rot door frame overall. Most other fiberglass doors are available with either wood door frames or fiberglass composite just on the lower 6-8″ of the door frame.  Our prehung doors are 100% fiberglass on the entire frame.

Plastpro full length lockblock

Plastpro doors have strength built into them. Notice the full length lock block on the leading edge.  All other manufacturers offer “extended lockblocks” 10-16″ at best.  This does not offer support or strength at your entryway. This is one major difference the consumer cannot see with visual inspection. Remember, the lock block (or stile) is hidden behind the exterior fiberglass edge.

We provide aluminum mill thresholds with fiberglass composite full length.  Fiberglass threshold support will never attract termites and will offer support when weight is applied.  Many thresholds have no  support so flexing and bending would be an issue.  Others have pine support which wicks moisture from concrete and attracts termites.And once termites find a food and water source they can searchhigher into walls and rafters.
