Building Layer

Most calculators tell you how much insulation to buy. Build Layer tells you whether your wall actually works. Stack your thermal buildup one layer at a time and watch the numbers respond in real time. Add a material, set its thickness, and the R-value climbs while the U-value drops. Fall short of your target? Solve for the exact insulation thickness you need. Worried about damp? Run a condensation check and see precisely which layer sits at the dew point. This is engineering, not guesswork — a pocket thermal lab for anyone insulating a home. What Building Layer does that others don't: → Builds walls, roofs, and floors as real layered stacks — drag, drop, calculate → Sums R across every layer and converts to U = 1/R against your target → Solves insulation thickness backwards from the U-value you're aiming for → Flags condensation risk between layers before it becomes mould → Compares before/after and estimates heat loss and payback Built for real work: Homeowners mid-upgrade, hands-on builders, designers, and amateur energy auditors who need a fast local calculation — no account, no cloud, no sign-up.
