Patination Oil

In damp or wet weather conditions, new lead can on occasion develop an uneven powdery white, non-adherent coating of carbonate. This can be washed off by rainfall and cause staining on materials below. To counteract this, Calder developed patination oil to prevent this from occurring.

GRP Valley Trough

GRP Valley Troughs provide an excellent alternative to traditional lead troughs. As well as being more cost-effective, they have a long life expectancy thanks to UV protected surfaces. They add a modern and clean finishing touch to almost any construction project. Made from glass reinforced polyester (GRP), which is lightweight and strong. GRP Valley Troughs are easy to install and maintenance-free. UV inhibiting film suppresses mould and fungus growth to a minimum, maintaining water flow over much longer periods than traditional troughs.
