How much insulation can you carry in your trailer or truck for each job? If you are installing blowing fiberglass you need less storage than you will for cellulose. Cellulose has less coverage per bag which requires a larger trailer or truck. More
Tips and Tricks
All machines, no matter what brand, will start to degrade in performance over time. Things wear out. The production performance happens so gradually that you may not even notice. So, how do you prevent a decline in production and keep your machine running efficiently? More
One of the most frequent problems we troubleshoot is trouble during dense packing. It can be a frustration. Dense packing takes time and there is no real good way to make this process go fast. HOWEVER, there are things you can do to maximize efficiency without having to wait 10 minutes for each cavity. More
The CM1500 and CM700 are simple machines to maintain and repair. With the quick release hopper and easy access to the sprockets and chain and to the blowers and agitators. Cool Machines has made your insulation machine ACCESSIBLE and as easy as a “plug and play.” You will not need to take it to a special service tech or send it off to the manufacturer for costly delays and repairs.

One of the biggest questions we are asked is when retrofitting an older house, how to be careful with knob and tube wiring. Its exposure in the attic and walls creates concern. The use of knob and tube goes back a hundred years. There is a good chance that the insulation on the wiring could create an issue. More
Insulation Methods with and without a Machine
No machine needed
Since the 1940’s, fiberglass batt has been and continues to be the most economical system for insulating your home. When installed properly, fiberglass batts still perform just as well as newer products.
Spray-in-Place Fiberglass / Cellulose
Machine needed: Insulation blower with recycling capabilities
Water is mixed with a fiberglass / cellulose / glue mixture and sprayed into the wall cavities.
Blow-in-Batt Fiberglass / Cellulose
Machine needed: Insulation blower with gauge to determine accurate pressure.
A less common technique for insulating a home is the use of high density fiberglass blown into the wall cavities. A net is stapled to the wall. Fiberglass or cellulose is blown through holes in the net filling the entire cavity.
This article and video shows a general maintenance routing on a CM2400. This unit has not been cleaned in THREE years (NOT recommended *smiley*). This machine has been abused and yet, its durability has withstood many hours of commercial work. The following are the main items to inspect, clean and maintain. Please note: While the airlock seals were changed on this machine, it is not a part of this video.
Dense Packing a wall, ceiling or floor provide a superior insulation performance. The density helps eliminate leaks and better controls the loss of heat and cool.
Dense Packing Walls
Dense packing existing walls is a traditional, time-proven technique to increasing thermal performance. Retrofitting does not always involve removing the interior drywall/plaster. Drilling a hole in the exterior or interior and sending a tube into the cavity is the best way to minimize retrofit costs.
In recent years, it has become popular to dense pack walls in new construction. Before the drywall is placed, insulation contractors have an option to pack the exposed cavities by using a material like InsulWeb. This material is applied to the wall by stapling it every inch. This provides a strong barrier to receive the dense packing of 3.5 psi. The contractor has a very good view of the cavity and how it is filled. Some manufacturers have created certifications to install their products. We do not advocate one material company over another. However, there are no necessary qualifications necessary to install cellulose or fiberglass in this manner. More
