Calculators for sheet metal and the building envelope
Calculators that run in your browser - nothing is sent anywhere until you ask AFS for a quote. Each result says what it is, how it was calculated and what it does not cover.
Flashing Profile & Bend Development
Legs, bends and hems to a blank width, bend schedule, weight and an AFS fabrication check.
Open calculatorMaterial Takeoff & Nesting
Pieces into 10 ft strips and 48 in sheets, utilization and weight, ready to send to AFS.
Open calculatorRoof Edge, Coping & Fascia
Edge runs, corners and terminations to pieces, joints, end caps and cleat length.
Open calculatorThermal Movement & Compatibility
Expansion and contraction of a run between metal temperature extremes, and dissimilar-metal screening.
Open calculatorPreliminary - review requiredRoof Drainage Flow Screening
Design flow from area and a sourced rainfall intensity, per outlet. Preliminary.
Open calculatorPreliminary - review requiredWind Uplift & Edge Screening
ASCE 7-16 edge pressures for comparison with ES-1 tested capacity. Preliminary.
Open calculatorWall & Roof Assembly R-Value, U-Factor & Dew Point
Total R and U-factor of a layered assembly, interface temperatures and a steady-state dew-point screen. Preliminary.
Open calculatorCladding Panel Layout & Opening Flashing
Balanced panel layouts, expansion-joint counts from thermal movement, and flashing cut lists for openings.
Open calculatorRoof Pitch, Area, Hip/Valley & Panel Coverage
Pitch in x:12, degrees and percent; sloped area, rafter and hip/valley lengths; standing-seam panel count and length.
Open calculatorGeometry, Slope & Unit Conversion
Exact unit conversion, right triangles, slope, a 1:12 ramp check and tolerance stack-up.
Open calculatorPreliminary - review requiredOccupant Load, Egress & Accessibility Screening
Occupant load, egress width and exit count from the factors you enter from your adopted code, plus a ramp slope check. Preliminary - not a code determination.
Open calculatorPreliminary - review requiredEmbodied Carbon, Insulation Comparison & Preliminary Envelope Loads
Embodied carbon of options from EPD factors you enter, insulation R comparison, and conductive heat loss Q = U·A·ΔT. Preliminary.
Open calculatorEnter it once
One project carries the profile, material and edge runs into every tool. Nothing is typed twice.
See how it was worked out
Every answer shows its status, the formula, the assumptions and the published source of each value.
Send it to AFS
The takeoff goes to the shop as a request for quote, stamped preliminary with its calculation fingerprint.
What these tools are not
They are design aids for preliminary sizing and quantities. They do not replace the engineer of record, the plumbing designer or the governing code, and no result is a fabrication release until AFS reviews it. Read the method sheets for exactly what each one covers.
