The connection of the castellated foil is done by a "push button technique". The foil structure allows pipe spacings of 50 mm and multiples. Diagonal pipe laying directly on the castellated foil on top of insulation without accessories is possible.
Size of templates is 1025mm x 1025mm x 18mm for estimating purposes allow 1 template for each square metre.
The templates overlap slighly and in doing so interlock together to provide a fast and extremely accurate way of installing circuits prior to screeding.
