Manufacturer's Instructions
We adhere strictly to the manufacturer’s load design charts, detail book, shop drawings, and product data, including technical bulletins, for installation.
Site Verification:
- We verify that substrate conditions are suitable for installation as per the manufacturer’s guidelines.
- Any adverse conditions are reported in writing, and installation only proceeds once these are rectified.
Installation
SIP Supports:
- We ensure a level and square foundation/structural system/substrate to support wall and/or roof SIPs.
- For wall SIPs, the sill plate is held back 12 mm from the edge to allow full bearing of OSB skins.
- Access holes are provided in plating to align with electrical wire chases in SIPs.
Pre-Lifting:
- We inspect and record any panel damage before lifting from the truck and obtain approval before using any damaged panels.
- The plate area is cleared of debris before SIP placement.
Positioning:
- SIP panels are positioned to align and level within ± 3 mm or as required by the manufacturer.
- Panels are installed as per drawings and design parameters, coordinating with other contractors for adjoining work.
SIP Fastening:
- SIPs are connected using specified fixings and sealant, ensuring a minimum of 25 mm thread penetration into the support.
- Plates and splines are used for joining SIPs, secured with nails, staples, or screws, and nailbond per manufacturer recommendations.
- Temporary props or braces are used to secure panels against wind loads until final support is provided.
- Panels are temporarily waterproofed during installation to protect from weather.
Restrictions:
- SIPs are not installed directly on concrete, and plumbing within SIPs is done only after consulting the manufacturer.
- Skins are not over-cut for field openings, and electrical chases are not cut into the skins.
- SIPs exposed to solvents and vapours that can damage the EPS core are avoided.
- Wet or damaged SIPs are replaced before proceeding with additional installations.
Protection
SIPs are protected from weather by installing wraps immediately, providing temporary protection until further construction covers the panels.
Completion
We provide documentation to the manufacturer confirming that the installation complies with the design and documentation requirements.
