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Reasonable care is taken when preparing the tools, but information may contain errors, become outdated or be unavailable.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.
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.
Questions about these terms can be sent to info@venttools.com.
