Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

How many fasteners does a rain-screen panel need?
It depends on the specific cladding system — check the manufacturer's installation instructions for the specified fastener count and pattern per panel, since this varies by panel size, material, and wind-load rating.
Does this include extra fasteners for cut or edge panels?
No — this calculates the base fastener count using a uniform fasteners-per-panel figure across the total panel count entered. Edge and corner panels that require additional fastening should be accounted for separately.
Does this include fasteners for the furring or substructure itself?
No — this counts only the fasteners attaching the cladding panels to the substructure, not the fasteners used to install the furring strips themselves.
