Product catalog summary
Introduction
Icopal's Elastoflex LWS Warm Roof Insulation System is designed for both new constructions and refurbishments, offering a cold-applied liquid waterproofing solution. It introduces two new insulation boards, Thermazone Elastoboard F and H, made from polyisocyanurate (PIR) for enhanced thermal efficiency.

Features & Benefits
- No Carrier Membrane: The boards are designed to work directly with the Elastoflex system.
- Interlocking Edges: Tongue & groove edges provide stability and reduce heat loss.
- Single Piece Boards: Factory laminated to eliminate on-site bonding.
- Reinforced Facing: Bitumen facing for stability and increased load tolerance.
- Fast Application: 'Wet on wet' application method speeds up installation.
- Guaranteed Performance: Supported by up to 20-year insurance-backed guarantees.

System Components
The system includes the Elastoflex membrane, Thermazone Elastoboard, PUR adhesive, Micoral SK VCL, Xtra-Seal SF Bitumen Primer, and various accessory products.

Thermazone Elastoboard F
- Facings: Multi-layered kraft paper and metal foil.
- Core: PIR with a density of 30 kg/m3.
- Environmental Impact: Zero ODP and low GWP.
- Application: Suitable for occasional foot traffic; requires a vapour control layer.
- Board Sizes: Available in various thicknesses from 30mm to 150mm.

Thermazone Elastoboard H
- Facings: Dense reinforced bitumen and multi-layered kraft paper.
- Core: PIR with a density of 30 kg/m3.
- Uses: Suitable for areas with frequent foot traffic.
- Application: Requires a vapour control layer and can be used with traditional finishes.
- Board Sizes: Available in thicknesses from 33mm to 153mm.

Tapered Insulation
Available in 1:60 and 1:80 falls to ensure proper drainage, with minimum thicknesses of 20mm and 30mm respectively.

Performance and Properties
- Compressive Strength: Exceeds 150kPa at 10% compression.
- Water Vapour Resistance: Greater than 40MNs/g.
- Durability: Indefinite life when correctly applied.
- Thermal Properties: Thermal conductivity of 0.023 W/m.K with varying R-values based on thickness.
