It's great that folks discuss different systems and different suppliers on the Homeone Forum, but how do you know if it's a genuine recommendation? If it's not, how do you know if the stuff is compliant?
Some may have seen my posts in a topic about windows from China where I asked one of the advocators, ostensibly a member of the public about the performance data - well that person waffled then disappeared, but there were other supporters who claimed to be customers - yet they never came forward to discuss the performance with me. The outcome is that these products are highly likely NOT compliant, and that is a serious problem because you may not be able to qualify for a certificate of occupancy. (Never mind the safety breaches which may be concealed).
Trust the experts who have been around a while, you don't need to buy their products and services to get an opinion.
If you buy products that turn out to be non-compliant, you have lost your money.
You don’t have to buy from me to ask questions. I will always help if I can.
Thanks
