High-end software, available to everyone.

TideWeld Software is a Nova Scotia company. We build our own products across building science and everyday use, to a standard we would rely on ourselves, and price them so one person can actually buy them.

Coldbridge

Psi-Value Calculator

The first of our products to ship. A two-dimensional thermal bridging solver to ISO 10211, built for the people documenting linear transmittance for NECB compliance.

Temperature field with isotherms and a grid of surface temperatures

Draw the section, set the boundary conditions, and get a Ψ value with the documentation to back it up. It runs in a browser with nothing to install.

The solver is checked against the reference cases published in ISO 10211 Annex C, and you can run those checks yourself from inside the software.

Designed by a practising P.Eng for energy advisors, energy engineers and building consultants.
