Protection for Insulating Glazed Units (IGUs)

Welcome to the world of windows! They are essential to buildings for architectural reasons as well as for performance reasons. Indeed, glass plays a key role: it offers light, protection, heat and/or insulation.

Why protect glass on construction sites? 

Windows are among of the first items to be installed in a new building, protecting it from the outdoor environment. For that reason it is highly vulnerable to damage during the remaining construction work, which may take months. We believe it is important to protect this valuable component as early as possible in its life cycle in order to protect it until the building has been completed. That is why we have developed a range of solutions specifically for IGUs.

Thanks to a protective film, the glass will be immune to the external attack that can occur at any stage of the glazing module's life cycle. No more cleaning or replacing will be needed on completion of construction and no more late fees and disputes! Customers are satisfied and returns are almost non-existent.

Forglass, the best IGU protection film

Novacel Forglass 9561 is applied when the insulating glass module is manufactured and stays on it until termination of construction work. 

This protective film is a remarkable shield against all types of environmental attack that glass can face on a construction site: cement, paint, silicone, grinding sparks, and more.

The Forglass range also comes with a 12-month warranty. This is the best warranty available on the market. 

It is designed to be easily removed in a single piece and without excessive effort, even after 12 months!

How is this protective film applied on glass? 

The protective film is ideally applied in the factory during the fabrication of IGUs using an application machine

Walco's VX2 vertical application machine allows Novacel protective film to be applied to both sides of the glazing with a free margin all around to allow the joinery to be assembled without trapping the film inside.


The machine adapts to all sizes of IGU, avoiding film wastage.

PVC and aluminum profiles are generally protected in the plants where they are produced.

This means that glazing and profiles are protected from the moment they are manufactured and their surfaces remain protected until completion of the construction work.

This procedure ensures the best possible application of FORGLASS 9561 and guarantees its effectiveness.
