Client Testimonials

Tracy P

We had the Houston Brothers install spray foam insulation into our attic at the beginning of the year and we are extremely satisfied with the end result. These guys were always informative from start to finish. They educated us on the product, what to expect during the spray in process and how it would make a huge difference in future power bills. Our central heating & cooling system doesn't work nearly as hard as it once did and the power bill reflected this change almost immediately.This process is worth every dollar you invest and the Houston Brothers are the right men for the job.

Most professional people I have used in a long time. They give you an accurate estimate of the work they plan to do. They show up when they say they will, and call you if there are any changes. They show up on time. They tell you what they are going to do when they start, they do the work in a professional and timely manner, and they tell you what they have done when they finish. I'm impressed with their work and product. I highly recommend them.

What are the Different Types of Spray Foam?

There are different types of spray foam densities and structures. An open cell spray foam has a lower density whereas a closed cell spray foam has a much higher density. We can help you choose the best type of foam for your project

Spray Foam is a spray-applied plastic foam that is sprayed directly onto walls, roofs, or whatever type of surface you want insulated. It is made of two different chemicals called isocyanate and poly resin.

Open Cell Spray Polyurethane Foam

It has a lower density and is sponge-like in appearance. Due to its expansion ability during the application process, open cell foam fills cracks and crevices while adhering to most surfaces, smooth or irregular.

Closed Cell Spray Polyurethane Foam

It has a higher density and each cell in the foam is completely closed. This type of insulation is more costly than open cell foam, but it provides a code-approved air barrier, vapor barrier and moisture barrier as well.
