22.5oC Ceramic Coating Treatment

Measurements
149 btuH energy transfer per sq.ft. Untreated Metal Roof
134 btuH energy transfer per sq.ft. Ceramic Coated

Net Result
15 btuH per sq.ft. of energy transfer
Total Net Result: 570,000 btuH (entire treated surface)


Remedial Roof Repairs (Grande Prairie, Alberta, Canada) – Alliances Pipe Line Company

Alliances Pipe Line CompanyProject
An Existing 6,000 square metal roof required repairs, due to leaking.

Problems
This particular roof accommodated (6) major A/C roof top units.

Conventional Repairs
The repairs would require expensive crane removal of all roof top units in order to re-apply a conventional roofing membrane system. This would disrupt a working staff environment and company operations overall for a lengthy period of time.The repairs would also involve the extra cost of re-installment of the A/C units after the conventional roof system was completed.

Delta T’s Metal Roofing Solution
Utilizing our Delta T Roofing CCC/100 system did not require the removal of the roof top A/Cunits,and we resolved all the problems.

Net Result
We saved the Company money without any disruptions to the working staff by using our CCC/100 Roofing Solutions.

Convenience Store BuildingProject
Retrofit to existing asphalt and gravel roofing system

Step 1
Remove all existing loose ballast by means of manual, or mechanical means, ensuring that existing membrane is free and clear of all dust, dirt, debris and whatever other particles that may be present on the surface that would impede positive adhesion of newly installed monolithic Delta T. roofing system membrane.

Step 2
Install a spray applied, or roll on rubberizer primer type monolithic roofing membrane coating, such as roofing products distributed by Tremco, or other similar companies specializing in roof monolithic spray, or roll on prime coatings.

Step 3
Spray apply CCC/ 100 Ceramic Insulation (2) coats in total, each individual coat @ 60 sq. ft. per gallon.

Caution
Each individual coat must be allowed to cure for 24 hours before applying the next coat
