Why should I build EPS/Epoxy boards? - There is a performance revolution going on, and it's not about pop - outs. Your customers are hearing about custom built EPS/Epoxy surfboards. Some of them have already ridden one and they have experienced the exciting difference this technology makes. Lighter, stronger, better flex, better feel and better response. Your customers want custom built EPS/Epoxy boards and will seek out those who make them. Now you can make them. Back to top

Why use sFoam blanks? - sFoam surfboard blanks have been six years in development. Our blanks have no problems with out - gassing, unlike extruded foams. sFoam blanks have no problems with laminate adhesion, unlike extruded foams. That means no de - laminations from trapped gas or poor surface adhesion, throughout the life of the board. sFoam blanks are cut with Computer Numerical Control from 2 lb. per cu. ft density EPS billets. This gives our customers the ability to create a blank to their specifications, without bending or twisting the blank. sFoam blanks are cut exactly to your pure curves. Using the tools you have now, you can be shaping sFoam blanks with little change in your current technique and work flow. We ship to any destination from our centrally located factory with the best shipping rates to most locations. Back to top

Can I just get a rocker cut and use my own outside outlines? - Yes, many customers prefer using their own spin plates and outlines. You can still take advantage of designing a rocker cut that fits your needs, if you can't find one in the stock catalog. Back to top

Do you sell blanks completely shaped ? - No. We cut accurate rockers and outlines only. It is possible to design a top and bottom rocker so that almost no thinning is required. Our accurate outline cuts eliminate the time required to lay out a template and cut it. The shaper has to turn down the deck and rails; add any concaves and vees and finish sanding in preparation to laminating. Our system is designed for the custom shaper who wants to save 35% or more of his shaping time. The shaper can turn his attention to the more finessed aspects of board building; for example, the rail shapes and the location and degrees of concaves and vees. The blank styles listed in the sFoam catalog could be considered as a reference point to a purpose built EPS blank. Back to top

Does EPS foam quickly become waterlogged if your board gets dinged? - The simple answer is NO. An immersion test of 1 cubic inch of sFoam, submerged in water for 1 hour, shows that our foam will absorb 0.36 milliliters of water. That is the equivalent of less than 7 drops. To put this into perspective, if you dinged your board and peeled off 6 square inches of glass and sealer to expose the raw foam, you would soak up 7 drops of water after being in the water for 1 hour. As you can see, this is a non - issue. sFoam is a special hi - density foam designed for hand shaping surfboards. A lot of the misconceptions of EPS foam come from early experimentation and use of water - soluble sealers ( spackling compounds ). This type of sealer will soak up water rather quickly and cause de - lamination problems. Check "Laminating Tips" in our FAQ section for a proven and approved method of sealing sFoam blanks.

Why does the blank have to be sealed before laminating? - If an EPS blank is not sealed properly it will absorb un - adulterated epoxy resin and prevent a suitable bond to the laminations. Sealing the blank by using a mixture of epoxy and Micro Balloons, lowers the viscosity of the resin and keeps it from penetrating too deep into the foam. This keeps the blank lightweight, and provides the optimum bond of the laminate to the blank. Check "Laminating Tips" in our FAQ section for a proven and approved method of sealing sFoam blanks.

Is EPS foam weaker than polyurethane foam? - In compression and in tensile strength, sFoam is stronger than the most common weight of surfboard polyurethane foam. In shear tests, common weight polyurethane foam is slightly stronger. However, any composite engineer will tell you that the true test of strength in any given surfboard is its panel strength. Panel strength is a factor of the distance between the top and bottom laminations of the surfboard, how strong the laminations are; and, any webs ( stringers ) between the laminations. The strength of the foam has very little effect on surfboard strength. It should be noted that sFoam weighs 41 % less than the most common weight of surfboard polyurethane foams yet has slightly better pressure - ding resistance than urethane foams. In addition, epoxy laminations are stronger than equivalent laminations using styrene resins. Therefore, a surfboard made with a sFoam blank & epoxy resin will be stronger than a board made with polyurethane foam & styrene resin - all other factors being equal. Back to top

Why does is cost so much to ship blanks? - Shipping companies use a formula called Dimensional Weight to help calculate their charges. . The large boxes needed to ship blanks, and the light weight of the product, make the Dimensional Weight much higher than the actual weight. For residential deliveries, freight handlers have to off load to smaller trucks, increasing their cost to deliver. sFoam has been able to negotiate very reasonable rates, and will continue looking for even better deals. Back to top

Occasional apparent voids between stringer and foam? - We make stringer cuts using our CNC hot wire cutter, which makes a absolutely straight cut (unless we making a custom elliptical stringer setup). Because the hot wire is hotter outside the foam during the cut, there is a kerf formed on both edges of the foam. This kerf does not go very deep and is usually shaped through. Also, EPS foam naturally has extremely small voids throughout it. These passage ways have no effect on the foam strength, but show up occasionally as a void against the stringer. After shaping, any of these voids are eliminated when you seal the blank, and are cosmetically fixed, automatically. Back to top
