Certificate Overview: The document is a certificate from the Irish Agrément Board for Solitex Plus and Solitex UD vapour permeable roofing underlays, confirming compliance with Irish Building Regulations 1997 to 2006.

Product Description: Solitex Plus and Solitex UD are spunbonded polypropylene roofing underlays for pitched roofs. Solitex UD is non-reinforced, while Solitex Plus includes PP-net reinforcement. Both prevent windblown rain, dust, and snow ingress and control condensation.

Usage: Suitable for ventilated and non-ventilated pitched roofs, either supported or unsupported. Solitex Plus offers enhanced tear resistance and flexibility at low temperatures.

Compliance with Building Regulations: The underlays comply with several parts of the Building Regulations, including materials and workmanship, structure, fire safety, moisture resistance, ventilation, and energy conservation.

Technical Specifications: Detailed specifications include dimensions, weights, tensile strengths, tear resistances, and water vapour resistances.

Installation Guidelines: Emphasizes correct installation for performance, including overlap guidelines, appropriate tacking methods, and additional protection at hips and valleys.

Quality Control: Manufacturing includes rigorous quality checks, complying with ISO 9001:2000 standards.

Specifications and Installation Guidelines: Eaves ventilation should include fly screens, and proprietary eaves ventilators are recommended. Vapour control layers are necessary for dormer roofs and non-ventilated cold roofs.

Non-Ventilated Roof Design and Condensation Risk: The underlays reduce condensation risk without air movement, requiring proper sealing and ventilation.

Design Data and Performance: Suitable for tiled and slated ventilated pitched roofs, offering superior strength and resistance to wind uplift.

Technical Investigations: The underlays have acceptable fire properties, negligible toxicity risks, and require routine maintenance.

Certification Conditions: Certified by NSAI, valid for five years if conditions are met. Compliance with Safety, Health and Welfare at Work Act, 1989, and other regulations is ensured.

Key Specifications and Conditions: Must be manufactured and installed per certificate specifications, with ongoing quality assessment by NSAI.

Limitations and Responsibilities: NSAI is not liable for product use, and installation instructions must be obtained from the manufacturer.

Revisions: In May 2007, Solitex UD and Solitex Plus were classified as vapour permeable underlays.
