Old Canaan Building Materials

The materials of traditional New England

Most things written about building materials are vague on purpose. "Natural stone." "Quality copper." "Traditional finish." The vagueness is not an accident — it is what lets an article apply to everything and commit to nothing. The Standard is the opposite. It is a refusal to leave the room until the material has a name, a grade, a thickness, and a reason.

A specification is not a suggestion. "Sixteen-ounce copper" is a different material from "twenty-ounce copper," and a roof built from the wrong one fails in a way that a roof built from the right one does not, twenty years from now, when no one remembers which article they read. The Standard exists because that distinction is usually the first thing cut from anything written for a general audience — and it is the only part that matters when you are actually building something.

Every entry in the archive ends with a Standard: a short, declarative paragraph naming exactly what to ask for. Not a brand. Not an affiliate link. The material itself, specified the way an architect would specify it on a real set of drawings, because that is exactly what it is.

The Standards below are a sample — one or two from each category in the archive. Each links to the full entry, where the reasoning behind the specification is laid out in full: what the material is, how it behaves over decades, and why the alternatives fall short.

Barn Red — What the Color Actually Was

Iron oxide pigment in raw linseed oil, thinned with turpentine for the first coat, for barn and agricultural outbuilding paint on traditional New England properties. The color should read as deep brownish red — not bright red. If the paint looks like a fire engine, it is the wrong color.

Pointing Mortar — Selecting the Right Type

Match mortar compressive strength to the masonry being repointed — softer than or equal to the masonry unit, never harder. For pre-1900 soft brick: natural hydraulic lime mortar or lime putty mortar. For post-1900 brick: Type N Portland-lime mortar at most. For granite and harder stone: Type N or Type S, depending on exposure. Sand color and texture must match the original. This is the specification that protects the masonry rather than the mortar.
