Insulated Metal Panel (IMP) Installation in Houston, Texas
Terrapin Construction Group is a self-performing IMP installation contractor with a Houston office at 825 Town & Country Lane, Suite 850, Houston, TX 77024, serving the greater Houston metro — from the Port of Houston and Barbours Cut to Sugar Land, Katy, and the Bayport logistics corridor. Our crews install Kingspan, Metl-Span, CENTRIA, and PermaTherm panels on Gulf Coast cold-storage, petrochemical, food-processing, and emerging data center envelopes, engineered for 160 mph hurricane design wind and Category 4 storm events.
Why Houston owners hire TCG to self-perform IMP
Houston IMP work lives or dies on hurricane detailing. A Gulf Coast envelope that passed spec at 110 mph will still fail if clip spacing, stainless fastening, or perimeter flashing is wrong. TCG self-performs panels — we don't sub-tier them — so the crew that reads the Houston wind calc is the crew that installs against it. You pay crew cost, not stacked subcontractor markup, and you get a single warrantor for panel, fastener, and flashing.
IMP systems we install in the Houston metro
- Gulf Coast Cold-Storage IMP4" to 6" polyurethane panels (R-32 to R-48) for refrigerated DCs along the Port of Houston, Bayport, and SH-225 petchem corridor. USDA / FM-approved systems.
- Hurricane-Rated EnvelopeConcealed-clip IMP with 16-ga exterior skin, stainless steel fasteners, and enhanced perimeter detailing for 160 mph design wind and Miami-Dade-equivalent impact resistance.
- Food-Grade IMPUSDA-compliant white-liner panels for meat, poultry, and produce plants in Pasadena, Stafford, and the Gulfgate corridor.
- Data Center EnvelopeHigh-R vapor-sealed IMP for emerging Houston data center clusters in Katy, Cypress, and the Energy Corridor — sized for 24/7 cooling loads.
- Petchem & Industrial IMPFire-rated and chemically-resistant panels for La Porte, Deer Park, and Baytown facilities requiring IBC Type II-B construction.
- Re-Skin & Post-Storm RepairFull-envelope retrofit of 1970s–90s tilt-up and pre-engineered warehouses damaged by Harvey, Ike, or annual Gulf weather events.
Houston project conditions we plan around
Houston envelopes must satisfy the 2021 IBC with Houston amendments, ASCE 7-16 / 7-22 hurricane wind loads, and Harris County Flood Control elevation thresholds for sites inside the 100-year floodplain. Coastal Houston projects within 100 miles of the coast trigger 130–160 mph ultimate design wind speed (Risk Category II), enhanced windborne-debris detailing, and concealed-clip panel systems. TCG defaults to stainless perimeter fasteners against Gulf salt corrosion, marine-grade sealants, and hurricane shutters/louver coordination. We coordinate truck routing around Beltway 8, Port of Houston HOV restrictions, and Harris County Permit Office inspection cycles — typically 48–72 hours for envelope sign-off.
Houston IMP project types
- Port-adjacent cold-storage DCs (Barbours Cut, Bayport Container Terminal)
- Last-mile Amazon / FedEx stations (Katy, Tomball, Humble, Pasadena)
- Food processing plants along the Ship Channel & SH-225
- Petchem support & laydown facilities (La Porte, Deer Park, Baytown)
- Data center envelopes (Katy, Cypress, Energy Corridor)
- Self-storage climate-controlled IMP (Sugar Land, The Woodlands, Pearland)
- 3PL distribution boxes off I-10, I-45, and US-290
- Post-hurricane envelope retrofit & re-skin
IMP cost benchmarks — Houston metro (2026)
Houston pricing runs slightly above the national average because hurricane design drives thicker gauge skins, stainless fasteners, and tighter clip spacing. The upside: Houston's open-shop labor market keeps crew costs competitive, and Gulf Coast port logistics shorten material delivery for Kingspan and Metl-Span orders.

Frequently asked questions — IMP install, Houston
What hurricane wind speed do Houston IMP envelopes need to meet?
Most Harris County commercial projects now require 130–160 mph ultimate design wind speed under ASCE 7-16/22 with Risk Category II, depending on site elevation and proximity to the coast. TCG designs every Houston IMP system to the governing code — not the minimum — and uses concealed-clip systems with stainless fasteners for coastal salt resistance.
Do you pull Harris County and City of Houston permits?
Yes. TCG coordinates City of Houston building permits, Harris County Permit Office approvals for unincorporated sites, and all envelope / structural third-party inspections. We also handle Port of Houston Authority permits for projects inside the port footprint and TCEQ air-quality permits when panel install is adjacent to active petchem operations.
How fast can TCG mobilize after a hurricane?
We maintain Gulf Coast panel inventory with Kingspan and Metl-Span for post-storm envelope repair. Our typical post-event mobilization is 7–10 days for scoping and 3–4 weeks for material release — faster than owners waiting in a rebuild queue with a sub-tiered panel contractor.
What IMP manufacturers do you install in Houston?
Kingspan, Metl-Span, CENTRIA, AWIP, MBCI, PermaTherm, FlexRock, UPI Panels, and Arch Solar polyiso. Houston-area distribution centers for Kingspan (Modesto/Deland) and Metl-Span (Lewisville, TX) shorten our delivery windows vs. northern markets.
Does TCG work on LNG or petchem IMP projects?
Yes — we install fire-rated and chemically-resistant IMP systems for support facilities, control buildings, and admin structures at La Porte, Baytown, and Deer Park sites. We do not perform inside the red-line process envelope, but we coordinate with owner EPCs for all adjacent construction.
What's the typical IMP lead time in Houston?
Kingspan and Metl-Span are running 8–12 weeks from Houston release. PermaTherm polyiso is often 4–6 weeks. For hurricane season (June–November) jobs we recommend releasing panels at design-development to protect schedule against Gulf weather delays.
