What's New
We have rebuilt Source 2050 to reflect the way high-performance projects actually are specified and sourced — quantities you can trust, freight you can see, and a growing roster of solutions.
Project management, right in your account
Improved project management right in your account. Designers and architects can build out project product selections, tag them in their drawings, and share them with their contractors. Builders can do takeoffs, choose from alternatives, and track orders all in one place.
Open Spec Lists
Real Time Shipping
If you order a pallet or more of material, real-time freight cost will be added to your cart at checkout — no more waiting for a quote. Already available for most of our palletized products, we will roll this feature out to more products and less-than-pallet orders in the future.
Insulation, thermal breaks and membranes
Our new Take Off Calculators allow you to find the correct product quantity based on total square footage. Number of packs, rolls, pallets or truckloads is calculated automatically.

Match Your Spec, Fast
Enhanced category filters allow you to find the product that matches your exact specifications. You can then select multiple products to compare their performance and cost side-by-side. And all product listings include their most current documentation, including EPDs, installation guides and other helpful materials.
