28' Round 54" Athena Pattern Beaded 20 Mil Liner | 4000 Series - Heavy Duty (HD) Beaded Liner | 5-2852-908-240

These liners are made by Hollowell Industries, Inc. (HII), the same company who makes the Doughboy above ground pools.  HII pool liners are the thickest liners available on the above ground pool market. Unlike the majority of other liner manufactures who use gauge to measure  liner thickness, HII uses mil.

 

Mil is an actual unit of measure used to specify the thickness of a material. While Mil is a standard unit, equal to one thousandth of an inch, gauge is a relative number and the gauge value is at the discretion of the company specifying the measurement.  This is especially true when used for stating liner thickness.  Mil thickness is the truest form of vinyl liner measurement in the industry. 

 

Doughboy’s use of virgin vinyl material sets their liners apart as a truly superior above ground pool liner. This premium material allows for greater plasticity, durability and greater integrity of the liner, therefor extending liner life. Doughboy liners do not contain plastic fillers like many other above ground pool liners on the market. The plastic filler used in these cheaper liners severely decreases the strength and life of the liner.

 

It’s the use of this superior materials and quality craftsmanship that allows Doughboy to offer their unmatched lifetime warranty on seam separation. 

 

1. Liner Thickness

     
• Doughboy liners are typically 40%-80% heavier in both weight and thickness.
       
     
• Doughboy liners have the same weight and thickness on both the     sidewall and the bottom. Commodity liners typically have thicker,     heavier sidewall than bottoms. Commodity liner manufacturers do this to     reduce the price of the liner, but only advertise the sidewall thickness     which can be misleading.
       
     
• Doughboy liners are manufactured with heavier vinyl material and will last 50% to 90% longer than commodity liners.
       
     
• Doughboy liners protect the sidewall and bottom of the liner     from tears, rips, punctures, and holes caused by foreign objects in the     soil, objects on clothing, windblown objects, lawn care debris, and     entry system (ladders & step) contact on the bottoms and sidewalls.
       
     
• The Truth About Liner Thickness
     
         
• Above ground pool liners are generally marketed and sold by         a thickness standard called gauge. Gauge is not a set number but is a        truly relative number and liner manufacturers that use this measurement         are allowed to determine which gauge they want to use for stating their         liners' thickness.
           
           The truest measure of a pool liner is done using an         international standard of mil thickness. This is an absolute fixed         measuring system. Just like an inch is an inch, so to is a mil. Above         ground pool liners because of the nature of the pools and their price         generally do not have as thick a liner as an in ground pool. Therefore         many of the above ground pool liner manufacturers started using gauge as         a reference to their particular liners' thickness.
           
           In the marketplace today there are really only two general         gauges; standard gauge and heavy gauge. We offer pools with standard         gauge and others with heavy gauge pool liners. Regardless of whether         it's standard gauge or heavy gauge most above ground pool liners last         anywhere between 8 and 15 years.
         
             
• Our liners are made by the leading industry liner manufacturer and come with a 100% Lifetime Warranty against seam separation.
               
             
• Our Standard Gauge is a more economical liner with acceptable thickness and wear considerations.
             
• Our Heavy Gauge liners are the thickest above ground             pool liners on the market today surpassing our standards for thickness             and wear.
             
• Our CaliMar brand above ground pools which are             manufactured by the same company who makes Doughboy pool and liners.             These are the only liners in the marketplace with a True 15, 20 miland25             milliner thickness. That's equivalent to an inground pool liner             thickness. Liners on CaliMar above ground pools come with a100% Lifetime arranty on seam separations, the most common failure point in liners.             
         
     

2. Raw Material Make-Up

     
• There are 3 major ingredients in the chemical makeup of a vinyl liner:     

     
1. PVC (Poly Vinyl Chloride) is the main building block that goes     into creating vinyl liners. PVC makes up 50%-60% of the total raw     ingredients.
        
     
2. Plasticizer (petroleum-based oil) is another key ingredient     that makes up 35%-40% of the total raw ingredients. This ingredient     determines the flexibility of the liner and increases its chemical     resistance and life span.
        
     
3. Inert Materials (calcium carbonate – a.k.a. clay) and Stabilizers make up 11%-30% of the total raw material ingredients.
        

     
• Doughboy liners have increased levels of plasticizer and low     levels of calcium carbonate. Typically raw material plasticizer costs     are 4-5 times more per pound than calcium carbonate. Doughboy liners,     with increased levels of plasticizer, will remain flexible during the     life of the liner providing a wrinkle-free installation and minimizing     UV fading. Commodity liners use a lower level of plasticizer (to save     money) therefore compromising the quality of the liner.
       

3. Liner Life Span:

     
• When comparing the purchase of Doughboy liners to commodity     liners (calculated over the life span of the liner), Doughboy liners     usually last 10-15 years. Commodity liners typically last 2-5 years.     Both incur the same cost for installation, water and labor.     

     
• 40%-80% heavier in both weight and thickness
       
     
• Same weight and thickness on both the sidewall and the bottom
       
     
• Made of a heavier vinyl material and will last 50%-90% longer
       
     
• Protect the sidewall and bottom of the liner from tears, rips, punctures and holes
       
     
• With higher levels of plasticizer, will remain flexible     throughout the life of the liner, providing wrinkle-free installation     and minimizing UV fading
       
     
• Typically last 10-15 years
