Structural Insulated Roofing for a Screened Room

Identification

• Structural insulated panels (SIPs) are often placed in the roofs of residential homes, as well as commercial buildings. According to the United States Department of Agriculture, these panels are composite products with insulated foam cores mounted between two sheathings. These products are designed to insulate homes and add strength to their structure. Structural insulated roofing panels can be placed on additions and existing homes alike. These panels make an excellent roofing material for screened-in rooms and garages.

Types

• There are several types of SIPs that can be placed on the roof of a screened room. Polyurethane insulated panels typically have an R-value of R-6 to R-7 per inch of thickness, which will keep energy costs steady. Polystyrene structural insulated roofing panels are also used in residential homes. These panels have an R-value of R-4 to R-5 per inch of thickness. Both types of structural insulated roofing panels will make the roof of your screened room stronger.

Installation

• Proper installation is key to getting the most benefit from structural insulated panels. Purchasing a high quality product is also important to maximize insulating benefits. These products must be glued together correctly by the manufacturer, pressed into place and cured for best results. No gaps can be present between these panels so it is best if they are installed by a licensed building contractor.

Considerations

• Structural insulated panels can also be placed on the ceilings and walls of your home at the time of construction. Some panels are large and heavy, so a crane is required to install them. Insecticides should be applied to SIPs before placing shingles or metal over them. Keeping indoor humidity levels below 50 percent will reduce the likelihood of mold growth on these panels. According to the United States Department Of Energy, installing a ventilation system inside your home will prevent moisture problems on SIPs.
