The purpose of insulation is to provide a continuous thermal barrier to minimize heat flow through the walls, floor and ceiling. Insulation serves the purpose of keeping a home comfortable and reducing energy costs. Incorrect installation will also lead to reduced insulation performance. For example, if the insulation is compressed or installed with gaps, especially in the case of roof insulation, there is bound to be a drop in its efficiency level. This is where commercial insulation plates play an important role.

Commercial insulation plates are primarily used for attaching insulation boards to all types of surfaces. An insulation plate is manufactured from recycled plastic. These commercial insulation plates are weather resistant. They are long lasting and provide high levels of durability. These qualities make it particularly advantageous to be used, especially in the roofing industry.

A commercial insulation plate is usually 0.375 inch (9.5mm) thick with a 3-inch (76.5mm) diameter and is especially designed to hold insulation and underlay boards under the roofing system.

Insulation plates provided by some companies includes a recessed diameter hole in the center, to prevent the fastener's head from coming in contact with the roofing membrane. To maintain the necessary strength, the insulation plate is manufactured with a thick center that embeds into the insulation and a thin flexible exterior to help reduce facer tear. In addition, anti-back out tabs that press against the fastener heads are also provided.

The method of fastening the roof insulation is generally explained in a manual or a specialized technician can be called upon to install it.

Every homeowner is constantly looking for ways to reduce utility bills. Many tell their children to turn off the lights and appliances, but do not recognize the benefits of using commercial insulation plates with regular insulation. Used along with insulation that is appropriately installed, there can be substantial savings.
