Insulation done with care, not guesswork
Every property is different, and every insulation project is different. Before we recommend anything, Shield Plus Insulation Masters takes the time to understand what your property actually needs.
We believe that quality work sometimes takes longer — and that the goal is to do the job correctly, not simply to get it done quickly. That's the difference you'll see from the first inspection to the final walkthrough.
- We inspect the property before recommending a solution
- We match the material to the project — no one-size-fits-all upsell
- We take the time to do the job right, even if it takes longer
Insulation solutions for your property
We offer multiple insulation options because every property has different needs. Our team takes the time to understand your project and determine what solution makes sense for your property.

Open Cell Spray Foam
A lighter, lower-density spray foam that expands aggressively to fill and seal large cavities. Open-cell foam offers excellent air sealing and sound dampening at a more accessible price point than closed-cell.
Learn More
Closed Cell Spray Foam
High-density closed-cell polyurethane foam expands to seal every gap, delivering the highest R-value per inch available, a built-in vapor retarder, and real structural reinforcement — a top choice for Houston homes.
Learn More
Fiberglass
A proven, cost-effective insulation used in walls, ceilings, and floors for decades. Fiberglass batts and rolls deliver dependable thermal performance where budgets matter.
Learn More
Mineral Wool
Dense, fire-resistant batts made from stone or slag. Mineral wool delivers strong thermal performance, excellent fire resistance, and superior sound control compared to fiberglass.
Learn More
BIBS System
Blow-In-Blanket System — loose-fill fiberglass or mineral wool blown behind a fabric mesh for a complete, gap-free fill that outperforms standard batts.
Learn More
Blown-In Insulation
Loose-fill insulation blown into existing attic floors and enclosed cavities — the fastest, most affordable way to add R-value over existing insulation or in hard-to-reach spaces.

Spray foam insulation
Spray foam is one of the most effective ways to insulate and air-seal a building at the same time. It expands on application to fill gaps, cracks, and cavities that traditional insulation leaves open — blocking drafts, moisture, and outside heat.
Shield Plus Insulation Masters installs two types of spray foam, and we help you choose the one that fits your property and your budget.
Open Cell Spray Foam
A lighter, lower-density foam that expands aggressively to fill large cavities — excellent air sealing and sound dampening at an accessible price.
Closed Cell Spray Foam
A dense, high-performance foam with the highest R-value per inch, a built-in vapor retarder, and added structural strength — ideal for Houston's heat and humidity.


We take the time to understand your project
Hi, I'm Eduardo Herrera. I started working in the insulation industry at 25 and built Shield Plus Insulation Masters around one simple idea: do the job the way I'd want it done in my own home. That means understanding your property first, recommending what's actually needed, and doing the work right — even if it takes a little longer.
Every project is different
No two properties — and no two insulation projects — are exactly alike. We treat yours as the one-of-a-kind job it is.
We take time to inspect
We walk the property, measure the areas, and identify what's actually needed before we recommend a single thing.
Quality over speed
Quality work sometimes takes longer. We'd rather do the job right once than rush it and do it twice.
Affordable without sacrifice
We aim for pricing that's fair and affordable — without sacrificing the quality of materials or workmanship.

Built on experience. Focused on doing things right.
Shield Plus Insulation Masters traces its roots to 2016, when owner Eduardo Herrera started another company with the same vision: help customers understand their insulation needs and provide quality insulation services.
The company was built on a simple belief — that insulation problems are often underestimated or misunderstood. Too many homeowners are sold a product before anyone has actually looked at what their property needs.
That's why we focus on inspecting the property, understanding the actual problem, and providing a solution based on what your property needs — rather than simply selling a product.

“Always do your best — like it was for you.”
That's the way owner Eduardo Herrera approaches every job. Do quality work with care, and it creates something that lasts — for the customer and for the community we're part of. When we treat your property the way we'd treat our own, the work speaks for itself.
The right insulation, installed right
We're not a one-product company. Whether your project calls for premium closed-cell spray foam or a cost-effective fiberglass or blown-in fill, we install the material that fits your property, your goals, and your budget.
Solutions for Every Budget
From premium closed-cell spray foam to proven fiberglass and blown-in options, we match the right material to your property and your budget — not a one-size-fits-all upsell.
Lower Energy Costs
Properly installed insulation seals the building envelope so your HVAC runs less against extreme Texas heat — which can meaningfully reduce your monthly cooling bills.
Moisture & Comfort Control
The right insulation and air sealing hold back Houston's humidity, reduce drafts, and protect framing from condensation and mold for a more comfortable, healthier home.
Installed Right the First Time
Every material only performs when it's installed correctly. No gaps, no compression, no voids — owner Eduardo Herrera is on site to make sure the job is done right.

Where we make the biggest difference
From retrofitting an old attic to insulating a brand-new build, we have the right material and the right method for the structures Houstonians actually own.
Existing Homes & Attics
Top up under-insulated attics or seal the roof deck to keep radiant heat out of your living space.
New Construction
Spray foam, fiberglass, mineral wool, or BIBS installed at the right stage of your build schedule.
Garages & Workshops
Turn an unconditioned garage into a usable, climate-controlled workspace year-round.
Commercial & Metal Buildings
Closed-cell foam for barndominiums, pole barns, and commercial structures that need moisture control.
Which insulation is right for you?
Not all insulation performs the same — and the best choice depends on your space, your goals, and your budget. Here's how three common options compare.
| Performance | Closed-Cell | Open-Cell | Fiberglass |
|---|---|---|---|
| R-Value Per Inch | R-6.5–7.0 (highest) | R-3.5–3.8 | R-2.2–3.2 |
| Air Sealing | Total airtight seal | Excellent | None (needs separate air barrier) |
| Moisture Resistance | Impermeable (Class II) | Permeable | None |
| Best For | Attics, metal, high-moisture | Sound & large cavities | Budget wall/ceiling fills |
