Ideal for use at sub-zero temperatures
When it turns bitterly cold on building sites in winter, our 818 Winter Schaum really comes into its own. Unlike other polyurethane foams, it can be applied at sub-zero temperatures down to -20°C without any difficulty. The reduced amount of moisture required by this product allows it to dry through uniformly – even on cold substrates and at low temperatures. 818 Winter Schaum adheres to all common building materials. And it is not only suitable for sealing perimeter joints on windows – it is also ideal for foaming in small gaps in walls, openings for all manner of conduits, and other cavities. The cured foam is semi-hard, predominantly closed-cell, and resistant to ageing and rot.
