Is the Insulation System in your Metal Building a Peak Performer?  If you don’t have the SNS® Continuous Insulation System, it is not.  Install the SNS® System and improve performance by as much as DOUBLE or MORE!

Sealed “N” Safe introduces its Continuous Insulation System for Screw Down Metal Roof and Wall Panels that can DOUBLE the energy performance of typical metal building insulation. The concept of Thermal Blocks has been used for many years with Standing Seam type roof systems without adding design issues. However, when applying thermal blocks in a screw down roof system, there are significant design issues to consider. Structural integrity can be greatly compromised. Water tightness becomes more difficult to maintain. Simply installing a “Foam Block” between the roof sheet and the purlin will prove to be your worst nightmare! The new “Sealed “N” Safe® Continuous Insulation System* is the solution. It is now possible to install a Low Cost Screw Down Roof, include one of the highest performing insulation systems available, maintain the structural integrity of your project, and create a watertight seal under the gasket of the roof sheet fastener. Best of all, save you a ton of money each month in energy costs. Yes, the “Sealed N Safe” Continuous Insulation System does all that! Is that “GREEN” you say? You be the judge!

Two Design Components make it work

Part One:  “Sealed N Safe”® Thermal Block* has an R5 minimum rating and is constructed of two galvanized metal plates with a specially designed isocyanurate foam injected between them. The Thermal Block is designed to resist normal vertical and horizontal loads applied in a typical metal building application. Complete test data is available on our website.

Part Two: Sealed “N” Safe® Fastener* Our specially engineered fastener has been specifically designed for the use with the Sealed “N” Safe® Continuous Insulation System*Use of this fastener is mandatory as it is key to the performance of the System*. This fastener is designed with two different thread types at two different locations of the screw shank. When driving the screw through the roof sheet and thermal block, and as the screw makes contact with the purlin, there are no threads at the upper location of the roof sheet and thermal block. This prevents “reaming” of the roof sheet and the thermal block around the screw shank while drilling through the purlin. Once the screw has drilled through the purlin and proceeds downward, the lower threads engage the purlin, while the upper threads engage the roof sheet and then the top plate of the thermal block. The roof sheet clears the top of the threads, the fastener contin­ues to run in and the top metal plate of the thermal block clears the threads, compressing the two together, forming a water tight seal of the fastener gasket. This also prevents “Reaming” of roof sheet and top plate of the thermal block to maintain a tight seal. By this time, the lower threads will have fully engaged the roof purlin, ran in tight, and compressed the complete system to the purlin. This design is not dependent on the tension of the fastener to the purlin to develop the required 50 lbs. of pressure to create and maintain a water tight seal under the fastener gasket. Compressing the roof sheet and the thermal block top plate together makes the seal. Sealed “N” Safe® Fasteners* are supplied as part of the system. No other fastener is to be used to fasten the roof sheet to the purlin with the Sealed “N” Safe® Continuous Insulation System*. The “Sealed N Safe”® Fastener* can be supplied in your standard colors. Simply give us a color chip and we will do the rest.

“Sealed N Safe”® Thermal Block* can be added to a single or double layer blankets over the outside or full cavity fill to create the SNS® Continuous Insulation System. The new Double Layer Insulation System for both roof and wall application is designed to reduce or eliminate the oil-can effect that happens with a 6” insulation blanket under the roof or wall sheeting. Double Layer Insulation System can achieve up to R-26 in both roof and walls (see cross-setional view on other side of page). When using a full cavity type system, we include our Insulation Support Rail which is fastened to the bottom of the purlin using #12 Flat Head SD Screw. It is a very attractive means of not only supporting the added insulation but also supporting the bottom flange of the purlin. It does not induce the tension con­ditions that are inherent when using banding or strapping to support the insulation. Our insulation support rails are produced in 10’-3” and 12’-3” lengths. 
 
The Building Designer must take one consideration into account. When placing a Thermal Block over the top of the purlin, it has a negative effect on the purlin design. We overcame that by adding the SNS® Purlin Strut. The values of Rτ for Purlin Rollover design needs to be .92 for gravity and .7 for uplift and must include use of the SNS® Purlin Strut. Additional costs are minimal. The system is simple and fast to install, saving you time and money. Over time it will save you lots of money, as much as ½ or even more, month after month, year after year in reduced energy costs and even pay for your building during its lifetime in energy savings. This is the highest performing insulation system with the lowest building cost method available today. See our “U” Value comparison chart for details on improved performance compared to conventional methods. You will be amazed at how much energy loss has been acceptable in the past and pleased to learn you don’t have to accept that any longer.
