Precision
manufactured to critical tolerances, the UniPul corrosion defiant door
system saves energy
and reduces overall life-cycle cost.
Pultruded FRP
doors, doorframes, window frames and louvers have thermal performance
comparable to wood and vinyl, are incredibly durable, virtually
maintenance free and perform as well as (and in many instances better
than) steel insulating doors, yet overall use less 'raw energy' (see:
embodied energy) in their production and life-cycle maintenance
than any other door construction material.
Beware, however, all FRP doors
are NOT created equal. Other FRP doors are manufactured using a
compression mold and/or hand-laid method, then assembled with metal
fasteners on an aluminum, steel or pultruded frame.

We offer the ONLY COMPLETE FRP
DOOR SYSTEM which is ENTIRELY PULTRUDED as a homogenous glass fiber
reinforced Isophthalic Polyester Resin shell hermetically encapsulating a
Polyurethane Isocyanurate core. This
lineal
thermoset composite polymer
structure delivers ultimate benefits sans drawbacks.
Our complete door
system
accepts any hardware including security electronics, is immune to
magnetism, rust and corrosion, insulates against heat and cold, resists
chemicals, salt air, physical abuse, chronic moisture, bacteria and
radiation and will not delaminate, chalk, craze, fuz or warp.

Pultruded fiberglass,
when compared to other common materials,
features the lowest embodied energy (low energy consumption in lineal
production) while providing the longest life expectancy. This has led experts to
recognize pultruded fiberglass as the most environmentally friendly system. ~GINLINE |

Pultruded fiberglass window lineals, the base for
window sash and frame construction, are created by pulling glass roving and
matting (high quality products should have 60% plus glass content) through
thermoset resins, a forming station and finally a sophisticated die. This
process creates an extremely tough material so tough it must be cut with diamond
bit saws in the fabrication process. The pultrusion process results in lineal
components that have excellent strength and, not surprisingly, similar expansion
and contraction characteristics to glass, a very stable material. Important
progress has been made by a handful of companies specializing in this field.
These companies have mastered the art of creating "thin wall pultrusions," which
demonstrate high performance levels and are cost effective for fenestration
applications. ~DUXTON |
