Manufactured as a Structural Insulated Panel (SIP), it combines insulation and boarding into a single step, eliminating the need for tedious manual framing systems like jacks, spacers, or brackets. It is an ideal energy-saving upgrade for residential attics, particularly where tight access or installation time is limited. Key Features SIP Panel Structure: Built with high-strength, moisture-resistant Type 3 Oriented Strand Board (OSB/3) facings on both sides. High-Performance Core: Utilises Stylite Plustherm Grey Expanded Polystyrene (EPS) for optimal thermal insulation. Draft-Proof Jointing: Engineered to slot together seamlessly, enhancing airtightness and energy efficiency. Multi-Application Versatility: Primarily built for lofts, it can also be configured as a strong walk-on warm roof deck for flat extensions. UK-Made Quality: Fully designed and manufactured in the UK. Core Benefits Boosts EPC Ratings: Significantly improves your homeandrsquo;s Energy Performance Certificate (EPC) ratings by lowering the roof component's U-value. Maximises Attic Storage: Creates a sturdy, safe walk-on platform capable of handling domestic storage demands. Rapid Installation: Slats together with precision, completely removing the need for on-site taping or sealing. No Squashed Insulation: Avoids the standard thermal performance drops caused by compressing traditional glass wool down into the joists. Applications Loft Storage Floors: Converts empty attic spaces into a solid, fully walk-on platform for household storage. Maintenance Walkways: Creates safe, structural pathways from the loft hatch to boilers, solar inverters, or water tanks. Flat Roof Extensions: Functions as a heavy-duty, load-bearing andquot;Warm Roofandquot; deck on home extensions or garages, ready for waterproof coatings. Fast-Track Building Projects: Used by professional contractors in tight spaces to install insulation and flooring simultaneously, saving hours on-site.
