DeltaGuard™ is a security window system developed by Thermosash for low to medium security human and physical structural impact project requirements. A specifically engineered frame and combined glass suite offering correctional facilities, youth detention, acute and forensic mental health facilities and data centre projects the peace of mind on entry or exit restriction and ballistic or blast control – protecting those that are in the building, behind our security façade systems.
Security window systems need to meet complex requirements for strength, safety, light and ventilation, easy cleaning, patient operation and staff control - consideration should be given to the type of glass, frames, fixtures and fittings that will be used in the design and manufacture of these products. The fixtures and fittings should be able to withstand targeted abuse and should not pose a threat or a risk of self-harm if damaged.
Impact Testing - Thermosash DeltaGuard™ system has been impact tested in IANZ accredited laboratory.
Design Considerations - Thermosash takes into consideration the specific design requirements unique to each protect including:
In order to create a welcoming yet secure facility, windows can include features such as stainless-steel mesh which guard the open area offering secure ventilation, and internal sliding sashes made to open at fixed positions which can be controlled by staff.
Thermal Performance - DeltaGuard™ can accommodate different IGU sizes. Although not thermally broken, the system can reach high thermal performances if coupled with an external secondary thermally broken system adopting an IGU. Each system is custom engineered for the intended use, span, and building construction.
Low-carbon aluminium window system - Thermosash partners with a local NZ-owned extruder achieving a much lower carbon footprint than the global average - offering reduced upfront carbon emissions. Our aluminium is 100% recyclable and all aluminium from refurbished sites and from our manufacturing process is environmentally managed back to our key suppliers and processed back into raw billet form.
Talk to us about your project early in the design phase so we can advise on the best options to meet specific safety and security requirements.
Sizing of units is subject to project security needs, and limitations may apply pending application and structural load intent - please contact us to discuss details / engineering requirements for your project.
Please Note: DeltaGuard™ is not intended for high security protection where we would recommend SÄLZER for medium to high end security, ballistic, intruder and blast protection. Talk to us about your project so that we can supply the safest product for you.

Our Expertise
Thermosash’s abilities have grown since its 1973 start-up when Laurie Hayes and his colleagues manufactured commercial windows out of a small production facility. It quickly became apparent that the products and skills of the workforce were creating a performing quality, flexible product that the market sought.
Over time, our teams of dedicated and committed people have grown, this has been possible through constant reassessment of internal and external processes and manufacturing methods from around the world. We’ve also provided ongoing reinvestment in the training of our people to ensure lean process, IT Systems, material handling machinery and transport logistics equipment, as well as design office and factory production process improvements. We are able to offer a world class company with manufacturing facilities in Auckland, Wellington and Christchurch.
