A growing collection of tools, guides, and project dashboards built for the people specifying and installing high-performance buildings. Some of these are live today; others are in development.
The Spec List — Your Project Dashboard
Live now. Save the products you’re spec’ing into named lists for each project. Share lists with collaborators, attach quantities and notes, export a clean cut-list or RFQ, and come back to the same dashboard from any device. Start one any time by clicking the Spec List icon at the top of any product page.
Take Off Calculators — Quantities Without the Arithmetic
Live now. Enter your total square footage and the calculator returns the number of packs, rolls, pallets or truckloads you need, with the coverage maths already done. Available on insulation, thermal breaks and membranes.
Immediate Freight Calculation — Real Costs at Checkout
Live now. Order a pallet or more and real-time LTL freight is priced into your cart at checkout — no waiting on a quote. Choose standard delivery or add a liftgate and see both prices before you commit. Already available on most palletized products, with more products and less-than-pallet orders to follow.
Product Comparison & Filters — Find It, Then Compare It
Live now. Filter any category by the specifications that matter — membrane type, permeability class, fire rating, dimensions, R-value — then put your shortlist side by side to compare performance and cost. Every listing carries its current documentation, including EPDs and installation guides.

Solution Sets — Complete Assemblies, Ready to Spec
Live now. Condition-specific wall assemblies and detail drawings — Delta Dörken stucco, lath, and drainage details, WickRight capstone & vent kits, and full exterior-insulation build-ups — built from products that work together.

The Source 2050 Window Schedule Tool — Your Schedule, on Your Schedule
Coming soon. Build a complete window schedule for a project — rough openings, glazing tier, performance targets, frame finish, install detail, hardware — then send it as a single RFQ to multiple window manufacturers. Track quote turnaround, compare offers side-by-side, lock the schedule into the project’s Spec List when you’re ready to order.
Window Installation — From Thermal Breaks to Expanding Tapes
Coming soon. A step-by-step installation guide covering the full rough-opening prep, sill pan + flashing, thermal break + buck details, air-sealing membrane choices, and the right expanding/compressed foam tape for each climate zone. Includes detail drawings and a printable checklist.
Insulation Guide — Choosing Materials, Formats, and Sizing
Coming soon. How to pick between batts, boards, and loose-fill for cavity, continuous, and below-grade applications. Material comparisons across stone wool, wood fiber, hemp, EPS, XPS, polyiso, and aerogel. Stud-spacing and substrate compatibility (wood vs. light-gauge steel). Sizing for R-value targets in IECC climate zones 4-7.
