Our IWI system is specifically designed for installation on solid wall substrates, as outlined in our design guide and in accordance with its intended purpose.
If you are considering using the system on anything else other than a solid wall, it is mandatory to consult our technical team beforehand.
They can assess your specific requirements, confirm whether the system is suitable for the property, and advise on potential solutions.
Since each property may have unique conditions, these assessments must be conducted on a case-by-case basis.
Failure to obtain our confirmation before proceeding may result in the rejection of your warranty application, as we uphold the highest standards of quality and compliance.
To help you avoid costly remedial work, we strongly encourage you to consult with us in advance. As your trusted retrofit delivery partner, we are always available to provide expert guidance.
