Garland Insulating

What Garland Insulating does

Garland Insulating Ltd. is a third-generation, family-owned insulation installation contractor headquartered in Dallas, Texas. Founded in 1948 by Paul Drum and currently led by Chairman Ferrell Drum and President Hayden A. Drum, the company installs fiberglass (loose fill and batt), cellulose, spray polyurethane foam (SPF), radiant barrier coatings, Tyvek house wrap, and complementary air-sealing/weatherization products. It operates five company-owned Texas branches (Dallas/Fort Worth, Houston, Bryan/College Station, Austin, San Antonio) plus a Denver, Colorado affiliate (Bison Insulation), employs 251–500 people, and holds HPIP Platinum certification across all Texas branches.

The company's revenue is generated almost exclusively through project-based, one-time installation services billed directly to homeowners, home builders, multi-family developers, and commercial contractors. Pricing is quote-based, set after free in-home energy assessments that include written ROI breakdowns. Sales channels are dominated by direct field sales — estimators dispatched from each branch — augmented by phone-based inside sales, Google Business listings, Angie's List presence, builder-association relationships, and federal tax-credit/utility rebate information. Distribution is fully direct; no e-commerce, marketplace, or reseller channels are used. Notable commercial projects include multiple 250–600+ unit multifamily complexes (Hanover Midtown Park, Loretto at Creekside, San Palmilla, The Atwood, The Highlands, Artistry Senior Residences at Craig Ranch) and a 20,000 sq ft metal-building re-insulation (Circle T Barn). Strategic supplier alliances cover Johns Manville, Owens Corning, Certainteed, Greenfiber, Demilec and Accella.

Garland's competitive position rests on training depth (1,200-hour on-the-job requirement before independent spray-foam work, proprietary JobWerks tablet application co-developed with RESNET), entrenched Texas builder and developer relationships, and multi-decade brand recognition in a fragmented trade. Recent strategic actions include the 2014 acquisition of Thermo Insulation, the 2016 launch of an adjacent gutters service line, the 2018 Denver partnership with Bison Insulation, and the generational transition of presidency to Hayden Drum. Revenue is not publicly disclosed and no institutional funding has been raised.

Products and services

• Fiberglass Loose Fill Insulation Light pink or white fluffy fibrous insulation made with 50% recycled material and naturally non-combustible. Installed by blowing into attics and hard-to-reach areas or behind netting in walls for new construction, achieving R-4.2 per inch at high density. Sold and installed by Garland Insulating across its Texas service area for homeowners and builders.
• Fiberglass Batt Insulation Fiberglass blankets (batts) friction-fit in wall and ceiling cavities during new construction, made with 50% recycled material, naturally non-combustible, and manufactured using bio-based binding products. Sold and installed as a standalone insulation product for residential and light commercial projects.
• SolarGuard Reflective Insulation Reflective insulation combining a high-performance fiberglass core with durable reinforced facings and reflective foil film, offering superior fire performance and thermal performance compared to bubble pack or foam core alternatives. Sold to homeowners and builders seeking higher-performance alternative to traditional radiant products.
• Tyvek HomeWrap Weatherization membrane providing a protective layer under siding over sheathing. Its nonwoven-fiber structure resists air infiltration and water intrusion while allowing moisture vapor to diffuse through, preventing mold and mildew buildup. Sold and installed as a standalone weatherization product.
• Spray Polyurethane Foam (SPF) Insulation Spray-applied liquid foam that expands to 100 times its volume to fill wall cavities, providing superior energy efficiency, improved indoor air quality, complete building envelope seal, and reduced airborne noise and dust. Garland installs SPF using 1,200-hour-trained technicians and partners with manufacturers Demilec and Accella.
• GreenFiber Cellulose Wall Spray Insulation Cellulose insulation sprayed into wall cavities with adhesive using a Multi-Matic blowing machine. Made from 85% recycled paper fiber, provides higher STC ratings than fiberglass, contains zero asbestos or fiberglass, and offers permanent fire resistance. Garland is the exclusive provider of GreenFiber cellulose for its projects.
• HeatBloc Ultra Radiant Spray Coating Water-based, low emissivity (low-e) coating applied to the underside of the roof to reduce radiant heat. Blocks 81% of radiant energy from the sun, reduces attic heat gain, and improves efficiency of existing insulation. Sold as a standalone radiant barrier service for Texas homes.
• Weatherization / Air Sealing Services Air sealing services including sealing around A/C ducts, doors, windows, ducts, outlets, electrical boxes, chimney flues, and attic chases. Marketed to reduce heating and cooling costs up to 50%, sold as a standalone service to homeowners and bundled with insulation retrofits.
• Free Home Energy Assessment Free in-home inspection evaluating attic efficiency through conventional methods including insulation, attic ventilation, and radiant spray. Includes a detailed written breakdown of options and potential return on investment. The assessment functions as a lead-generation service to convert homeowners into installation projects.
• Crawl Space Insulation Service Installation of insulation in crawl spaces to increase energy efficiency of air conditioning systems, keep homes warmer in winter and cooler in summer, and prevent moisture-related damage. Sold to homeowners across Garland's Texas service area.

Others

• GreenFiber: National manufacturer of cellulose insulation and a core supply partner of Garland Insulating. Included as an ecosystem participant rather than a direct competitor, given Garland's exclusive use of GreenFiber cellulose products and the close commercial relationship.

Direct peers

• USA Insulation: National franchise specializing in retrofit wall foam insulation and home energy efficiency upgrades. Directly comparable in the homeowner retrofit and energy-efficiency segment, with similar spray foam emphasis and free in-home assessment sales approach.
• Dr. Energy Saver: National home energy retrofit brand specializing in insulation, air sealing, and weatherization. Comparable to Garland in the homeowner energy-efficiency segment, with broader national reach but a more focused retrofit-only positioning.
• Bison Insulation: Denver-based insulation company in which Garland has invested and which Garland supports with leadership and capital. Directly comparable regional specialty contractor serving commercial, multifamily, and single-family residential customers in the Denver metro.
• Koala Insulation: Franchise-based residential and commercial insulation installer operating across multiple U.S. markets. Comparable to Garland in its homeowner-focused service model, with a different growth strategy (franchising vs. company-owned branches) but overlapping customer base and product set.

Broad incumbents

• TopBuild: Public national installer and distributor of insulation and building products (NYSE: BLD), formed from the merger of Service Partners and Masco Contractor Services. Comparable as a national insulation installer serving residential and commercial builders, with the scale to bid against Garland for large multi-family projects.
• Service Partners: National distributor and installer of insulation and building products, now a subsidiary of TopBuild. Comparable to Garland as a specialty contractor serving homebuilders, with national reach that Garland can only match through partnerships like Bison Insulation.
• Installed Building Products: Public national specialty contractor (NYSE: IBP) that installs insulation, waterproofing, and other building products for residential and commercial customers. Directly comparable in core insulation installation services, with a much larger geographic footprint and PE-style acquisition strategy that Garland competes against for multi-family and commercial work.
