ASME PVHO Acrylic Fabrication

Acrylic Windows
There are few companies in the United States that offer the full range of design, fabrication, and certification of ASME PVHO acrylics.

Acrylic viewports are used in human occupancy applications or in vessel design applications where acrylic is under high pressure and where human presence in the vicinity becomes a safety concern. This includes transparent vacuum chambers for testing and research, space vehicles or underwater habitats.


Hydrospace provides full engineering services for new or replacement windows, including documentation and certification for a wide range of existing systems that require maintenance, parts, or modifications. Customers may find themselves outside compliance regulations due to incomplete, erroneous or missing certification documentation. In difficult cases, customers have high value assets that require life extension certification or long-term solutions for more effective safety management within their organization. Hydrospace has helped hundreds of customers around the world with their acrylic PVHO windows, repairs, replacements, new documentation, certifications, and a better understanding of the quality assurance program to secure their long-term compliance with jurisdictional authorities.


Hydrospace works with all classification societies when third party inspections and surveys are needed. For many customers, Hydrospace is contracted to do full hydrostatic pressure testing for their windows, simplifying the replacement process. Hydrospace has full ASME PVHO pressure testing capabilities and provides the final PVHO hydrostatic pressure testing certification.
