VentTools is provided as an independent calculation and reference aid. You may use the website for lawful personal and professional purposes. Do not misuse the website, attempt to interfere with its operation, introduce harmful code or use automated access in a way that creates unreasonable load.
Fire and smoke damper installation is life-safety work. Results must be checked by a competent person against the current manufacturer documentation, project specification, approved construction details and applicable site requirements before work proceeds.
VentTools does not provide engineering design, product certification, Building Control approval, manufacturer approval or project-specific professional advice. A calculator result does not authorise a departure from a tested installation method.
Reasonable care is taken when preparing the tools, but information may contain errors, become outdated or be unavailable. VentTools may change, suspend or remove tools without notice.
Product names and references belong to their respective owners. Links to official documents are provided for verification and convenience. Users remain responsible for checking that the linked document is current and applies to the exact product and installation.
Unless stated otherwise, the VentTools interface, original written content, photographs, diagrams, calculator implementation and the original selection, organisation and verification notes within its engineering database are protected material. You may use calculator results for lawful site work, but you may not copy, republish, sell, redistribute or adapt the website or its original content into another service without written permission.
This does not claim ownership of manufacturer material, underlying mathematical facts or methods. Permission and licensing enquiries can be sent to info@venttools.com.
To the fullest extent permitted by law, VentTools is not responsible for loss caused by relying on the website without carrying out the required independent checks. Nothing in these terms excludes liability that cannot legally be excluded.
