Insulation Types We Offer

At MTZ Insulation, we offer multiple high-quality insulation solutions to meet the diverse needs of Denver homeowners. Our expert team will help you select the perfect option based on your specific requirements and budget.

  • Open Cell Foam Insulation

    For maximum energy efficiency, our open cell foam insulation expands to create an airtight seal that blocks air leakage while providing excellent R-value. This premium solution helps Denver homeowners achieve significant energy savings year-round, tackling both our brutal winters and increasingly hot summers. It's particularly effective for difficult-to-insulate areas and new construction.

  • Closed Cell Foam Insulation

    Our highest-performing option, closed cell foam insulation offers superior insulating properties with the highest R-value per inch. This dense, moisture-resistant solution not only insulates but also adds structural strength to your home. Perfect for Colorado's varied climate conditions, it provides exceptional protection against air infiltration, moisture, and extreme temperatures. Ideal for crawl spaces, basements, and areas where space is limited but maximum performance is required.

  • Fiberglass Insulation

    The time-tested solution for Denver homes, our fiberglass insulation provides excellent thermal performance at an affordable price. Perfect for attics, walls, and floors, this non-combustible material creates an effective barrier against Colorado's temperature extremes while being budget-friendly for many homeowners.

  • Cellulose Insulation

    Our environmentally-friendly cellulose insulation is made from recycled paper products treated with fire-retardant. It excels at filling irregular spaces and provides superior sound dampening properties. This option is ideal for existing Denver homes needing better insulation without major renovations, effectively sealing out those cold mountain winds.

Our 5-Step Insulation Process

At MTZ Insulation LLC, we've developed a thorough, transparent approach to ensure your Denver home or business receives the highest quality insulation service. Here's how our unique process works:

Personalized Consultation & Assessment

We begin with a comprehensive on-site evaluation of your property, examining your current insulation, identifying problem areas, and discussing your specific comfort concerns. Our Denver-based experts analyze your home's unique architecture and exposure to our local climate conditions to develop a tailored solution.

Customized Insulation Strategy

Unlike one-size-fits-all approaches, we create a detailed insulation plan specifically for your property. We consider Denver's dramatic temperature swings, your energy usage patterns, and your budget to recommend the optimal combination of insulation types and placement for maximum efficiency.

Thorough Preparation & Protection

Before installation begins, our team carefully prepares your space by protecting your belongings, establishing proper ventilation, and ensuring all safety protocols are in place. For removal projects, we set up specialized containment systems to prevent dust and debris from spreading throughout your home.

Precision Installation & Quality Control

Our experienced technicians install your insulation with meticulous attention to detail, focusing on complete coverage and proper depth. Throughout the process, we conduct ongoing quality checks to verify that every inch of insulation meets our exacting standards and will perform effectively in Colorado's unique climate.

Final Inspection & Performance Verification

We complete each project with a comprehensive walk-through to demonstrate the work performed and answer any questions. Unlike many contractors who rush to the next job, we take time to verify thermal boundaries, check for gaps, and ensure your new insulation will deliver the comfort and energy savings we promised.

4 Reasons you should replace your old insulation Denver County

01

Save Money

Denver homes go through a lot because of the changing seasons, which can be hard on our heating and cooling systems. If you get the right insulation, you can save money on your HVAC bills and keep your home cool in the summer and warm in the winter.

02

Keep out pests

Bugs may be in your attic, basement, or cellar. If found, replace the insulation after repairing any damage. This prevents future swarms and odors from waste. Sealing the attic also blocks entry points for rats, which can raise energy costs.

03

Experiencing drafts

Anywhere there are drafts, like in the attic, by a door, or next to a window, they are a big problem. Some small problems can be dodged with creative sealing, but the places that are giving you trouble will probably need more insulation. Drafts might be a pain, but they can save you a lot of money in the long run.

04

Sound Pollution

Do you ever realize how much noise your family makes? Children like to play with loud toys while parents try to enjoy a calm TV. It happens, and it most likely causes some friction.



Soundproofing insulation improves your quality of life by minimizing noise pollution inside. We can incorporate this into the construction or remodeling of your home, or we can easily retrofit existing homes. Whatever your home is like, you can benefit from less noise and more calm.`

When and Why to Consider Insulation Removal and Replacement for Your Denver Area Property

Property owners should consider removing outdated insulation when the ceiling no longer retains heat effectively, causing a spike in energy bills from providers like Xcel Energy. Compromised insulation can lead to increased energy waste and discomfort within the living or working area, making removal a first step toward more efficient energy use.


Deteriorating insulation materials can become less effective over time, necessitating removal for the health and safety of a property's occupants. An upgrade to higher quality options not only aligns with Xcel Energy's efficiency standards but also enhances the comfort and functionality of any residential or commercial space.
