| |
| Below you will find a small sampling of the many projects in which the Hawaiian SunGuard Waterproof Membrane was successfully installed. |
| |
| BEFORE |
AFTER |
 |
This recent Brai style flat roof had many leaks due to the roof seams that kept coming undone in the high heat.
|
|
|
 |
| After our Full Fabric Reinforced Roof was put in place there were no leaks. The ponding water here is no match for our HSG which contains the miracle polymer "LIpaCryl." It resists any ponding water which will evaporate within 48 hours of no rain. |

|
|
| |
| |
| BEFORE |
AFTER |
 |
| Years of neglect and patchwork repairs had resulted in 55,000 square feet of roofing problems. |
|
|
 |
| With reinforching fabric and coated ducts this roof is cool, watertight, and guaranteed for 10 years. |
|

|
|
|
| |
| |
| BEFORE |
AFTER |
 |
This 16-story Waikiki Hotel had a pitch and gravel roof that leaked from everywhere.
A lot of mechanical equipment, lines, and penetrations made this building a challenge for conventional materials. |
|
|
 |
With all of the gravel removed from the roof, epoxy primer was applied to the roof deck and high-tensile fabric was embedded in the foundation coat and two topcoats made this roof as good as new.
|
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| This low-slope shingle roof had leaks around almost all of the penetrations (vents, skylights, etc.) |
|
|
 |
| Sealing all of the penetrations and reinforcing with fabric made this leaky roof in Kaneohe watertight. |
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| Take a look at this old, EPDM (rubber) roof near Sand Island. Imagine how HOT it must have been inside this building. |
|
|
 |
Hawaiian SunGuard fluid applied membrane over EPDM. How cool does this old leaky, black roof look now?
|
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| This mechanical storage building had worn-out capsheet and the temperature was unbearable. |
|
|
 |
| The surface has been restored, repair people can comfortably work inside and it looks great. |
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| LEAKS, LEAKS, and MORE LEAKS. Halawa Valley metal roof could not keep tenants dry. |
|
|
 |
| Using fabric in the foundation coat on seams and penetrations guaranteed this roof for 10 years. |
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| No leaks at this home in Kalihi, just the scorching sun forcing the homeowner to run AC all day. |
|
|
 |
| Problem solved with 4 gallons/100 sq. ft. of Hawaiian SunGuard coating: 9°cooler inside. |

Numerous leaks originating from the seams of the rolled-roofing and parapet walls on this building in Kaneohe.

 |
| This leaky roof had two types of materials that didn't match and couldn't keep out the rain. |
|
|
 |
| Tinted to match the original color, Hawaiian SunGuard waterproof membrane made everything watertight. |

| Cool Classroom Challenge |
| |
Location: Honolulu Waldorf School
Date: 10/04/2006 at 1:36 pm
Weather: Sunny / Light Trades
Roof: Light Brown Shingles |
| |
| With excellent ventilation, room temperatures felt comfortable on
the day we did our test. However, teachers and staff agreed that without trade
winds the rooms get very hot and stuffy, which is why they initially called us.
The uncoated roof heated to 150.2 degrees in October (not even the hottest part of the year.) The adjacent Hawaiian
SunGuard roof remained a
relatively cool 88 degrees.
More surprising were the results on the flat rolled-roofing. Even on the newly
installed white cap sheet, surface temperatures reached 136 degrees (bottom
right photo). On the underside, Hawaiian SunGuard was responsible for
lowering ceiling temperatures by an impressive 16.9 degrees. This is important
because ceilings will radiate heat and increase the interior temperature. |
| |
|
| |
 |
| |
 |
| |
 |
| Using an infrared heat gun, the ceiling temperature at Barber's Point Elementary averaged 89.8° before Hawaiian SunGuard was applied. The ceiling temperature measured 69.4° after Hawaiian SunGuard was applied. |

Location: Barber’s Point Elementary
Date: 10/10/2006 at 12:45 pm
Weather: Sunny
Roof: Brown Cap Sheet
In the heart of Oahu’s Ewa Plain, Barber’s Point Elementary gets
baked by the sun. The combination of brown cap sheet and pitch / gravel roofs
makes for a giant heat trap.
Hawaiian SunGuard Installed SunGuard Temp Brown Cap Sheet
With a thick concrete slab
roof deck over most
classrooms, we were not
expecting to see the
dramatic results normally
observed on open-beam
ceilings. However, the
results were impressive.
The temperature difference between the untreated and coated surfaces was an
astonishing 70 degrees. Even more surprising was the temperature on the
underside of the roofs. The ceiling temperature of the uncoated classroom was
almost 20 degrees hotter the Hawaiian SunGuard cool roof. |

The Honolulu Advertiser
"COOL ROOF" PROGRAM SMARTER FOR SCHOOLS
The headlines "Beach Erosion 'Widespread'" and "It's Like Studying in a Sauna" (August 6) could together be titled, "Hawai'i shooting itself in the foot."
The cause of beach erosion is the rising ocean level, which is caused by global warming. Global warming plus hot-box classrooms create sweat. The "solution" is air conditioning, which burns more oil for electricity, which causes global warming, which raises ocean levels and causes higher land temperatures, which necessitates more AC. It's a devilish downward spiral.
Air conditioning classrooms is like putting ice cubes in ovens. Many older classrooms were inadvertently designed to collect heat. A group of selfless businessmen have donated time and materials to create "cool roofs" at Waipahu High School. Cool rooms reflect, rather than absorb the sun's heat. The result is classrooms that feel a good 8 degrees cooler.
Spending tax dollars to AC old hot boxes is like subsidizing state cars to run on flat tires. Each school will spend millions to install AC and the electricity cost will rise by $87 per student per year, year after year after year. Isn't there a textbook and computer shortage?
Finally, AC'd classrooms are often boarded up. Scientific tests show that students with good outdoor views perform 20 percent better than those with poor views. The new DOE leadership is committed to green school design and that's great. Meanwhile cool roofs plus super-efficient ceiling fans will dramatically cool down most existing classrooms. Tax dollars for cool roofs will not only cool down classrooms but also contribute to a cooler earth and stabilized ocean levels.
