The Insulate Thermal Deck Board is an innovative, all-in-one structural insulation panel designed to create a safe, fully walk-on loft floor and storage platform. 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 home’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 "Warm Roof" 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.
- Insulate Thermal Deck Boards combine insulation and loft flooring in one easy-to-install solution.
- This ‘All In One Solution’ improves EPC ratings and laves labour costs
- Its compact board size – 295mm x 1200mm, ideal for lofts with tight access
- Its high compressive strength and moisture resistance – creating a walk-on loft floor and storage area
- Ideal for loft conversions, loft storage areas and roof insulation upgrades.
