PART 3    EXECUTION
3.1	EXAMINATION
A.	Examine substrates, areas, and conditions under which insulation panels will be applied, with installer present, for compliance with requirements. Verify surfaces and conditions are suitable prior to commencing work of this Section. Do not proceed with installation until unsatisfactory conditions have been corrected.
B.	The substrate must be clean, dry and level, and free of sharp objects or edges.
3.2	INSTALLATION
A.	Insulation boards shall be installed per manufacturer's published installation instructions, and applicable codes. The manufacturer's published installation instructions shall be strictly adhered to, and a copy of the instructions shall be available on the jobsite during installation.
1.	Panels should be laid break bonded where practical, with joints lightly butted. There should be no gaps at abutments.
2.	Where runs of panels do not accurately fit the dimension of the roof, the use of Kingspan infill strips is required to make up this difference. 
a.	Strips to be the same thickness as the panels.
b.	Cutting should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side.
c.	Ensure accurate trimming of infill to achieve close-butting joints and continuity of insulation.
3.	Kingspan Optim-R or Kingspan Optim-R infill panels should be restrained to the roof substrate using a suitable adhesive and / or double sided adhesive tape or overburden. See project specific details.
4.	Kingspan overlay should be laid as soon as possible to avoid exposure of the Kingspan Optim-R to direct foot traffic.
5.	At the perimeter of the roof and where upstands or any penetrations (e.g. drainage outlets) are present, Kingspan infill strips should be laid abutting these areas, to take account of building tolerances.
6.	A minimum distance of 12 inch (305 mm) should be maintained between the top of the insulation upstand and the bottom of the horizontal roof insulation.
7.	Roofing System VIP panels can be laid in any weather, but care must be taken in windy conditions.
8.	Insulation can be lifted to allow inspection of the waterproofing system. 
9.	Additional insulation can be added at a later date on top of the VIP panels.
10.	Kingspan wind uplift warranty is available.
3.3	FIELD QUALITY CONTROL
A.	Owner's Inspection and Testing: Cooperate with Owner's testing agency. Allow access to work areas and staging. Notify Owner's testing agency in writing of schedule for work of this section to allow sufficient time for testing and inspection. Daily inspection and testing may be required. Do not cover Work of this section until testing and inspection is accepted.
B.	Do Not Do the Following.
1.	Walk directly on panels. A protective foot or crawl board should be used during the installation process.
2.	Expose panels to solvent based adhesive systems.
3.	Expose panels to excessive heat or open flames.
4.	Cut or puncture panels. Replace any cut or punctured panels. 
3.4	PROTECTING AND CLEANING
A.	Protect insulation board from damage during installation and remainder of construction period, according to manufacturer's written instructions.
1.	Coordinate with installation of insulation panels to ensure exposure periods do not exceed the manufacturer's recommendations.
