1.Composition of SSAP-GFR(Glass Fiber Reinforcing)Sheet and its Features

• SSAP- GFR SHEET

• SBS modified Bitumen laminated with Glass Fiber Fabric impregnated with Acrylic Resin on the TOP + Fine SAND on the  bottom
• Characteristics
1. Glass Fiber Fabric guarantees  FIRE RATING of Class A
2. Glass Fiber Fabric impregnated with Top White Acrylic can meet Energy Saving Requirements
3. SBS modified bitumen is a most common economical waterproofing material in the market
• Conclusion

: SSAP- GFR is an most ideal sheet which can satisfy both Fire Rating of Class A  and Energy Saving  Requirements.

: Ideal Roofing System with ECONOMICAL Cost.

2. 'I' - Joint Cold Liquid Welding Mechanism

Unique SSAP Sheet Joint Installation is Sealing the Gap and Filling the Void between two sheets ends about Half inch apart with Polyurethane or Polyurea.

• Liquid Polyurethane or Polyurea will Seal the Void or the Gap between two sheets completely and  will cure to  SOLID STATE.
• “I” Shape Sealing between two sheets can be completed with No Leakage Failure because the Liquid penetrates any eventual holes and builds up to the surface, which can be checked visually.  
• Cold, Room temperature application and curing Without Solvent Evaporation.
• Easy Material Handling with Simple Equipment.
• Polyurethane / Polyurea Gap Sealing can be completed by machine pouring or by spraying in a few seconds / minutes
• “ I “ Shape Sealing Mechanism at the Sheet Joint is the Subject of US Patent Protection. (US Patent 6,460,304).

3. Comparison of “I”Joint vs  Overlapping Heat Welding Joint

Existing Overlapping Joints		Unique & Revolutionary “I”-Joint

• Overlapping Joint has TWO POINTS at which Water Blocking must occur simultaneously, which are Point A  (between  Bottom of  top sheet and Adhesive material ) and Point B (between Top of bottom sheet and Adhesive material) , but the “I”-Joint needs Water Blocking only at ONE Point S (Top of sheets and Adhesive material) and the LIQUID STATUS of the sealing material Polyurethane or Polyurea) works With Gravity. This allows better bonding compared to Point A of  the Overlapping Joint  which works Against Gravity.
• In some installations more than 3 or 4 plies are created, which are not consistent and are vulnerable to leaks at each of the overlapping points,  but the “I”-Joint has only ONE ply and ONE side allowing for a very consistent mechanism.
• The Overlapping Joint cannot be corrected  by VISUAL INSPECTION. This can cause bigger problems when the work force is not trained well. However, the “I”-Joint can be inspected and corrected easily. For example, in Korea,  a lot of Overlapping Joints had leakage problems due to the impossibility of visual checking on the job site, but, since implementation of the  “I”-Joint, they  have 0% leakage problem, all because visual checking is possible and corrections are immediate.
• SSAP System Installation can be done by any workers who are trained on job site within one hour

4. Comparison of  SSAP Roofing System and Traditional Sheet Installation

- At the point of Corners, Curves, Around Protrusion and Around Drains

Traditional Sheet Installation		SSAP GFR Roofing System

• Possible Problems of Traditional Sheet Installation
• Corner : More than Two Folds of the Material may happen and this makes tight sealing difficult.
• Protrusion : Protruded Vertical Side  Sheets will be split and cannot be connected, nor sealed easily, resulting in leakage of the sheet and a greater chance to become detached.
• Penetration : Penetrated Holes will have side Sheets which will be folded making it very difficult for tight sealing.
• Problem Solved by SSAP Sheets and LAMS (Liquid Applied Membrane)
1. SSAP GFR Sheet can be installed by simple laying down of the material on the Flat Horizontal Area
2. Except on Flat Surfaces, NO Sheets will be applied.  
3. The Polyurethane or Polyurea Liquid bonds well to NON-FLAT Areas and also to flat SSAP Sheets as laid out. (It does not bond to EPDM or TPO).

5.  Unique Partial Bonding and Liquid Nailing to the Substrate

• Saves Bonding material and Labor Cost
• Completed Roofing is less effected by Building Material or Movement than Full Bonding over the entire roofing surface because most parts remain  LOOSE LAID.
• Liquid Nailing creates No mechanical defects on building substrate and results in a Higher bonding force than mechanical nailing due to larger Area Bonding with Polyurethanes instead of Point fixing.

6. Negative Pressure Generation and Wind Up-Lift Solution

• Installing Wind Force “SSAP Air-Moisture Ventilation System” at proper spots generates Vacuum between SSAP GFR Sheet and Substrate.
• Partial Bonding and Air Bridge between Units area allows for Air flow around entire area.
• Wind Up-Lift Resistance can be increased by Vacuum between Air Bridged Loose Laid Sheet and Substrate with our SSAP Moisture/Air Ventilation System. (Korea Patent No. 0258535)
• Ideal Solution to  Wind-Up Lift Problem..

7. Energy saving by White Top Coat

• SSAP-GFR Sheet is designed for Energy Saving by impregnating the Fiber Glass Fabric with approved white acrylic resin in Factory
• SSAP-GFR tape has the same structure of SSAP-GFR sheet and impregnated with approved white top coat
• Lower Operating Expense because of Energy Saving Program
