Free Static & Thermal Calculations

A key advantage to our Downer Designer is the fact that it also allows you to attain we static and thermal calculations, tailored to your individual project and configuration of your facade.

Precise & Professional

Downer Designer is a free optimisation and calculation tool which we offer as part of our service. An innovative software which intuitively provides fast and effective calculations, even down to the insulation depth you will need to achieve your target U value. Our service dynamically regenerates the bracket point loss 3D models to accurately calculate the through-wall thermal report.

Fast & effective results!


Downer Designer helps take the headache out of your project planning by helping you optimise your framing solution.

Our Downer Designer serves as a guide

Although we are the first to say we are extremely proud of our Downer Designer and the reporting outputs it delivers, it cannot replace a thermal consultant or surveyor.

Our thermal service was designed to calculate project specific bracket chi values also know as point loss chi.

Please note the thermal report is not a specification document. Our optimisation service can be used to calculate an optimum thickness of one insulation layer within the wall build-up in combination with our support system.

Thermal service is not a layout / take-off service. Our service can calculate up to 3 varying general area calculations. Further required calculations and / or full layout / take-off calculations should be provided by an appropriately qualified thermal consultant.

Soffit areas and static calculation corner areas are excluded from this service.

Please note condensation reports are not included in our offering.

Downer Designer static calculations service and thermal service are interlinked and the thermal service is not available without project specific static calculations from Project Builder.
