5. Please note all in joist systems require the pipe spacing to be 200mm apart or less This means you need to select a conservatory style kit or a multiple room kit standard room kits are designed with the pipe spacing at 250mm centers which would mean you would not have enough pipe in the kit e e e e e e Installing water underfloor heating over existing floors is simple using our different installation solutions Our overfloor systems can be installed directly over any solid subfloor such as existing floorboards plywood or concrete screed floors or any solid surface such as existing tiles wooden floors Technical support PLASTIC EGG CRATE SYSTEM CLIPPED DIRECT WITH STAPLES s e Ey gt _ ifi mE a MA ue e e e o
