Frame + Insulation Package
Structural frame combined with engineered cavity insulation, external structural sheathing and climate membranes.
Package Scope & Engineering Overview
The P2 Frame + Insulation Package takes the structural skeleton one step further by factory-integrating the internal cavity insulation and external structural sheathing. Designed to eliminate on-site fitting errors, this package includes non-combustible A1-rated mineral rockwool engineered specifically for the profile depth (e.g. 90mm or 140mm), external moisture-resistant structural sheathing boards, and variable-permeability vapor control and breather membranes. It provides the building with immediate structural bracing and thermal acoustic dampening, while leaving windows, roofing finishes, and external facade insulation to be customized locally.
Factory Production & Supply (Included)
- ✓ All P1 Structural Frame components: CNC S350GD+Z275 steel frame, anchors and statics
- ✓ Non-combustible A1-rated high-density mineral rockwool cavity insulation fitted for profile depth (90-140mm)
- ✓ External structural sheathing boards (OSB/3 moisture-resistant or structural fiber cement boards)
- ✓ Intelligent variable vapor barrier membrane for internal side of the exterior wall assembly
- ✓ High-performance breathable weather-resistive barrier (WRB) membrane for exterior side
- ✓ Specialized acoustic dampening decoupling tape for floor joists and wall sole plates
- ✓ Engineered sealing tapes, grommets and adhesive compounds for airtight junction sealing
- ✓ Laminated assembly guide and thermal bridging reduction shop drawings
Local Site & Client Scope (Excluded)
- ✕ Excavation, groundworks and reinforced concrete foundation slab
- ✕ Roof final coverings (roof tiles, standing seam sheet metal or flat roof membrane)
- ✕ Triple-glazed external windows, sliding patio doors and security entry door
- ✕ Continuous exterior insulation (ETICS/EWI) and final facade rendering or rainscreen cladding
- ✕ Internal drywall plasterboards, interior room doors, floor coverings and tiles
- ✕ Building services: Heat pump, MVHR ventilation system, plumbing and electrical installation
- ✕ On-site crane, lifting equipment and local construction crew

Who Is This Package Best For?
Builders and homeowners who want the framing and internal cavity thermal physics perfectly matched from the factory, but prefer to source windows locally to match regional architectural guidelines or install exterior cladding through local craftsmen.
Logistics, Packing & Customs
Delivered bundled with weatherproof pallet wraps. Steel components and insulation boards are packed for sequence-based crane offloading. Full export documentation, ATR certificates and customs clearance included.
Frequently Asked Questions about P2
Yes. All mineral rockwool supplied in the P2 package is certified Euroclass A1 (non-combustible according to EN 13501-1), with a melting point exceeding 1,000°C, releasing no toxic fumes during fire exposure.
The external sheathing and weather-resistive membrane provide temporary weather protection for up to 90 days. However, permanent roofing and exterior cladding should be installed promptly to protect insulation integrity.
For passive-level thermal and airtight performance, window sub-frames, EPDM perimeter tapes, and thermal bridge breaks must align perfectly with steel studs. Package P3 delivers these factory-engineered and pre-tested.
