The standard double glazing used for this comparison is clear float glass with air gap, the specification varies a little between suppliers except that Dowell does not provide a non-argon gas result thus their window will appear to be Uw -0.1 better than the others (the other windows can also take argon gas). The results are all similar in performance except for Dowell which uses argon gas, and AWS which is the least energy efficient. Note, the Uw value is critical but so too are the heating stars in Victoria because Victoria is a heating climate. There is little difference in heating stars for the top 3 brands. 'EcoEco' guarantees their prices will be the best for the customer and in most cases closer to 70% of thermally broken and uPVC. If you have any questions about these results please send them to me or post them on the forum. Thanks Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

No-one can give you legal advice on a forum, but you would need… 3 5480 Thanks. There are plenty of builders around my suburb. I'll make sure to do some door-to-door knocking, or note their building details on the temp fence. 4 4753 |
