I am considering buying a conservatory which uses Eurocell Logic roof and windows. The product looks OK and has BBA certification so I assume that it is a good system. However the Conservatoryonline website claim that Synseal is the only complete conservatory system where the roof completely matches the windows. This is a very bold statement. Does anyone know if it can be taken seriously. Also how good a product is Eurocell Logic compared to the highly regarded Ultraframe system.
