Wall Spray Cellulose Insulation

Blown cellulose is a great option for attics and retrofit applications where the dry fiber can be supported by an attic floor or enclosed wall cavity. But damp-sprayed cellulose provides an effective solution for open wall cavities in new construction.

Dampened cellulose is a sticky material. It is sprayed directly into open wall cavities between the studs, right against the exterior sheathing, where it stays put. It provides a solid, airtight and completely filled wall cavity. The basic cellulose fiber used in the sprayed application is the same as that used in the blown application: recycled newsprint with chemical additives. The difference is that sprayed cellulose is dampened with water and sometimes a little adhesive is blended into the mix.

Dry cellulose fiber is blown from a machine through a 2 1/2-inch hose much like its dry-blown counterpart. However, a water hose with high-pressure nozzle resembling a pressure washer is attached to the end of the fill hose. It sprays the fiber with a mist of water as it is fired from the hose. The spray dampens the surface of wall cavity at the same time to provide a sticky contact bond between the framing materials and the insulating fiber. The flow of water is adjusted by the applicator to establish an important balance. The fiber must be damp enough to stick permanently to the wall, yet not so wet to cause moisture problems. The damp fiber is shot until the wall cavities are overfilled, just proud of the wall thickness. The overfilled walls are then scraped flat to match the exact thickness of the wall framing using a rotating brush called a scrubber.

Sprayed cellulose is an eco-friendly material that is installed at a high density. Coverage is complete. There are no voids in the walls. All wire and plumbing penetrations are automatically and completely sealed. Our professionally installed application is airtight, comfortable, energy efficient, and safe. There are fewer thermal short circuits and virtually no convective currents within the wall cavities. On the whole, customers report a less drafty, more comfortable living experience. As a bonus, the superior air-tightness and absorptive qualities of sprayed cellulose provides a quieter indoor environment – sound proofing.

What Our Clients Are Saying

Joy & I were recently talking, and we decided that doing the insulation was probably the best money we have spent on this house so far.
Our house is more comfortable and we’re spending less on utilities.
Great job all around!

Blown in cellulose insulation. Job was completed to an excellent standard at a very reasonable price. After the job was completed, and without being prompted, Brian followed up with a reminder and necessary paperwork to apply for the Energy Tax credit.

Company responded quickly to our inquiry. The materials used were more pricey than a normal insulation job, however, the quality was significantly better than our previous products. The company worked to ensure that we were satisfied and did some additional work that wasn’t included in the estimate. I would highly recommend this company and we will be using them again.

SPS was great ! They arrived on time, were delightful guys and did a great job. They were also immaculate in their work, fully sealing off the attic area to prevent dust, tarping over my stairs and hardwood floors, and vaccumming when they were done. I would highly reccommend SPS and would hire them again if we needed additional insulation work. of heat.

They did a very good job, and were very thorough. Price was reasonable. They were on time and clean.

Easy to schedule. Straight forward and honest with the quote. Completely accommodating. A delight to work with in every way! Top notch work as well!

I had a handful of insulation contractors come out to my house to quote me on insulating my attic and some knee walls as well as look at sealing up my crawlspace. Brian was the only one who when talking to i got the sense of him actually knowing what he was talking about. SPS ended up insulating my attic with blow in cellulose, sealed my attic door and added some in the stairway to the attic. They also opened up a kneewall in my upstairs room and insulated that as well. My top floor is now MUCH more comfortable in both summer and winter then it was before.

On top of that they also fixed a dangerous vent fan for me (was a fire waiting to happen, replaced that one properly and did two others for me), sealed my crawlspace where i had open access to the outside (havent seen a mouse since, plus no longer need a dehumidifier!) and insulated and sealed open areas of my garage/house border.

They went above and beyond and did fantastic work and have recommended them to anyone who has asked!

Brian and his team are absolute experts in their trade. My home had unique issues in that the wall depth was not uniform making the option of using rolled batt fiberglass impossible, I was also very worried about future mold issues in our cathedral ceiling. Before we hired SPS I did pretty extensive research on this issue and was worried about finding a contractor with enough knowledge to put my mind at ease. Brian came in and basically he could have written the articles I read. He was so well versed in all methods and knew exactly what was needed (a combo of cellulose and spray foam). My job was done very thoroughly, quickly and came in cheaper than I thought it would. I cant recommend SPS enough. Thanks again Brian and team.

They were very good. I liked their service. They worked very efficiently. They did quality work. It did make a difference in my house. I did feel warm immediately. So I am planning to use them in the future.
