Wholesale Insulation Supply
Trade pricing and pallet-to-truckload volumes on XPS, EPS, ICF forms, mineral wool, tapes and fasteners. Stocking programs, job-lot quotes, and scheduled site deliveries for builders, GCs and dealers.
One envelope company · four divisions
Build it tight. Insulate it continuously.
Northmark Building Group supplies, specifies, and installs high-performance building envelopes. From a pallet of XPS delivered to your yard to a finished ICF structure, the same wall science runs through everything we do.
What we do
Four divisions, one philosophy
Each division stands on its own — but together they cover the whole path from material to finished wall.
Construction Consulting
Building envelope design, continuous-insulation detailing, energy modeling, code-compliance paths and ICF specification support — for architects, owners and contractors who want the wall right before it's built.
ICF Construction & Installation
A licensed builder division that stacks, braces, reinforces and places Insulated Concrete Form structures — foundations, above-grade walls, safe rooms and full custom homes — with our own trained crews.
Northmark Online Store
Buy insulation by the board, bundle or pallet with card checkout and freight quoting — XPS, EPS, ICF blocks, mineral wool and the accessories that go with them. Same products, no account required.
The through-line
We only sell what we'd build with
Because our crews install these assemblies and our consultants model them, the products in our warehouse are chosen for how they perform in a real wall — not just what moves fastest off a pallet.
- Continuous exterior insulation detailing that actually gets built
- ICF systems we stock, spec and stack ourselves
- Thermal, air-barrier and moisture guidance from people on site
- One point of contact from material take-off to final inspection

How a project moves through Northmark
Spec → Supply → Build
Specify
Consulting sets the envelope target — R-value, air-tightness, moisture strategy — and produces the details and product schedule.
Supply
Wholesale (or the online store) delivers the exact materials on the schedule, in the quantities the details call for.
Build
The ICF builder division — or your own crew, with our support — puts the wall up the way it was drawn.
