Insulation that actually works — from attics to shipping containers.
We install high-performance spray foam and insulation systems that block extreme temperatures, stop condensation, and lower energy bills — for homes, garages, crawl spaces, and a specialty most contractors don't touch: shipping container conversions.

- Cut energy bills year-round
- Stop condensation & moisture damage
- Even out cold, drafty rooms
Every space loses heat differently. We insulate for each one.
An attic, a crawl space, and a bare steel shipping container all lose conditioned air in completely different ways — which means they need different fixes, not the same blanket approach every contractor defaults to. Under-insulated spaces bleed energy every single day, showing up as high utility bills, cold or drafty rooms, and — in the case of an uninsulated steel container — condensation that leads straight to rust and mold.
We install the full range — spray foam, blown-in, and batt & fiberglass — and we pair it with honest diagnostics so the material actually fits the problem.
And because we saw real, consistent demand for a service almost nobody offers well — shipping container insulation — we built it into a core specialty, not an afterthought.

Specialists who do it right.
Matched to the space
We don't push one product everywhere — the right R-value and method for an attic, a crawl space, and a steel container are all different, and we spec each one on its merits.
The whole system, one crew
Removal, insulation, and air sealing handled together, so your new R-value actually performs — no gaps, no finger-pointing.
Honest cost guidance
We give clear, itemized quotes and tell you plainly what your project actually needs — no upsell, no guesswork.
Bare steel has zero R-value. We fix that properly.
Shipping containers sweat, rust, and lose or gain heat fast without real insulation. Closed-cell spray foam bonds directly to the corrugated steel, acting as both a vapor barrier and an insulation layer in one step — for container homes, offices, studios, and cargo or cold-chain storage.

Insulation FAQs
Yes — Conex Insulation works with homeowners, container-conversion builders, and property owners nationwide. Tell us about your project on the quote form and we'll confirm scheduling for your location.
It depends on your climate — colder regions generally target a higher attic and wall R-value than milder ones. We'll help you figure out the right target for your specific home rather than quoting a one-size-fits-all number.
Yes — it's our signature specialty. Bare steel containers have zero natural R-value and sweat badly with temperature swings. We install closed-cell spray foam, which bonds directly to corrugated steel and acts as an insulation layer and vapor barrier in one step, for container homes, offices, and cargo/storage conversions.
It depends on the space. Spray foam delivers the highest R-value per inch plus a built-in air seal, ideal for rim joists, crawl spaces, and shipping containers. Blown-in is fast and cost-effective for topping off attics. Batt is a reliable, economical choice in open framing and new construction. We recommend the right combination for your project rather than pushing one product everywhere.
The federal 25C and 25D energy-efficiency tax credits expired December 31, 2025, so they don't apply to 2026 installations. Many states and utility companies still offer their own rebate or weatherization-assistance programs — availability varies by location, so ask us and we'll help you check what's currently available for your address.
Yes. An under-insulated attic, wall, or crawl space is constantly bleeding conditioned air, which forces your HVAC system to run harder and longer. Bringing your home up to the right R-value and pairing it with proper air sealing is consistently one of the highest-return home improvements available, regardless of climate.
