Pro Plus Heat Shield

STS Heat ShieldHeat Shield in crawl space waterproofing

Our STS Pro-Shield Plus Liner has multiple functions. One of the great functions is, being used as a Heat Shield in crawl spaces for the floor above. The use of the STS Heat Shield is highly recommended for cold climate areas. Manufactured with a 99% pure radiant heat-reflecting aluminum foil on one side and white poly on the other, with reinforcing fiber grid sandwiched in-between. The STS Heat Shield is easily stapled to the bottom of the overhead floor joist (crawl space ceiling) with the aluminum foil side facing up. Before installing remove any insulation that may be between the joists, this is for two reasons. The first is, that if the insulation is damp or has come in contact with water it is a breading ground for mold and mildew. The second is the most important, for the STS Heat Shield to reflect the heat back to the living area there needs to be an open air space for the heat to travel freely. The 99% pure aluminum foil reflects the radiant heat that passes through floors of the living space above back into the home. This reduces overall heat loss through the floor by over 50% and keeps floors comfortably warm.

The STS Heat Shield for crawl space insulation is non-toxic, non-irritating, and Class A/Class 1 Flame-Retardant rated with low smoke spread and Tax Credit Certified. For more information about heat-reflecting aluminum foil go to Crawl Space Energy Conservation or Product Data.


STS Seam Lock

STS Seam Lock is a rubber based adhesive roll tape, 1" wide x 100' long, that has a release paper, that when removed and placed between the overlaps of the STS Pro-Shield Plus Liner, provides a second, stronger and more permanent seal than just the seaming tapes themselves. Apply to dry surfaces, stays pliable and will hold up to wet or dry conditions after bond is made, permanently bonding materials. Click for Product Data


Sump Pit Cover and other accessories:

STS Quite Clear Check Valve:

The STS Quite Clear Check Valve allows you to visually watch the water flow and insure that the valve is working properly. The Quite Clear Check Valve is designed to be glued onto a 1-½” PVC pipe, yet can be removed by loosening the two couplings for easy cleaning of sand, dirt or debris build up, if necessary. A properly working check valve will prolong the life of your sump pump by not allowing the water in the discharge pipe to flow back into the pit, causing the pump to cycle more often then necessary. Installing as new or replacing that old black enclosed check valve, the STS Quite Clear Check Valve is the valve for you! View Flier

STS-Sump Pit Seal:

The STS-Sump Pit Seal is ideal for new or existing sump pits in crawl spaces or basements. Fits up to 21” diameter pits and has a clear window for easy inspection into the pit. When using with our STS Pro-Shield Liner System, install the Sump Donut mounting plate under the liner and seal the liner to it, then bolt the 2 piece cover on top of the liner and bolt into place.
