Draw exact sill pan, head flashing, and jamb trim profiles on a precision grid — get an instant fabrication quote and place your order. No more waiting on the shop for a price.
Window installations live and die by water management. Sill pans and head flashings need to be exactly right — but the process of specifying and ordering custom profiles is broken.
A sill pan that's 1/4-inch too shallow or missing the correct dam height can cause a callback months later. Specs need to be exact.
Waiting days for a quote on custom aluminum sill pans means your window delivery arrives before the flashings — stopping the job cold.
Bending flashings on-site to compensate for stock that doesn't fit wastes labor time and often produces inferior water-shedding geometry.
Verbal spec discussions with the shop leave you without documentation if a wrong part arrives or a warranty claim arises later.
Trimgy's drawing tool was built around the same constraints brake operators work with — so what you draw is exactly what gets fabricated.
Draw your sill pan with precise dam heights, sloped floors, end dams, and drainage legs. Every dimension snaps to 1/4-inch — no ambiguity.
Specify aluminum (.032", .040", .050", .063"), galvanized, or Galvalume. Pick the right gauge for the application — commercial vs. light commercial — and see pricing update instantly.
LTL freight for long bundles of window trim is included in the quote before checkout. No surprise add-ons.
Your profile drawing is transmitted to the fabricator digitally — not re-typed, not re-sketched. The exact profile you drew is the one that gets bent.
Order sill pans, head flashings, and jamb trim in a single project. Track each profile separately; check out together.
Saved profiles mean repeat window jobs — same building, same spec — are re-ordered in seconds, not re-drawn from scratch.
From simple sloped sill pans to complex commercial head flashings with integral receivers, Trimgy handles any profile definable in straight-line segments.
A window installation company needs job-specific aluminum sill pans with integral end dams for a commercial medical office building.

Trimgy supports all brake-formed window flashing profiles: sill pan flashing (with end dams), head flashing, jamb flashing, casing trim, subsill extensions, and custom window surround profiles. Sill pans are the most critical — they must be drawn with the correct back leg height (minimum 1 inch behind the window frame), sloped bottom, and end dams. Trimgy's grid tool makes these dimensions explicit and precise.
A properly dimensioned sill pan flashing has four key elements: (1) a back leg at least 1 inch tall behind the window frame, (2) a sloped floor (minimum 1/8 inch per foot toward the exterior), (3) a front leg turned down at the exterior face, and (4) integral end dams at each side. The overall sill pan width must accommodate the full window rough opening plus 3/4 inch on each side for end dam coverage. Trimgy's precision grid ensures these dimensions are captured exactly as drawn.
For window sill pan flashing, .032" aluminum is the most common material — it resists corrosion, is light, and bends cleanly for end dams. Galvanized steel (26 ga.) is acceptable but should be avoided where dissimilar metal contact with aluminum or treated lumber may cause corrosion. For high-end applications where color match matters, Kynar-painted .032" aluminum in a color matching the window frame finish is a common specification.
Measure the rough opening width and depth. In Trimgy, draw the sill pan cross-section profile — back leg, floor, front turn-down — on the 1/4-inch grid. Enter the total linear footage (opening width + 1.5 inches for end dams, multiplied by number of windows, converted to linear feet). The fabricator receives exact dimensions and cuts pans to length with end dam bends. For end dams, note them in the order comments — they are typically field-bent from the sill pan material or ordered as separate preformed pieces.
