What is the difference between 5mm toughened and double glazing in relation to an energy report? Does the double glazing still comply with the Bal 19 standards? Thanks Re: URGENT HELP NEEDED BAL RATING 27Oct 13, 2020 9:21 am The structural Integrity ie loads, forces ,fire, etc, takes precedence over energy , but you will often hear builders, designers and building surveyors say they are equally important and quote some deem to comply ( DTC) solution where alternatives can be engineered and certified. Double glazed 5mm Toughened glazing is over kill ( lol, Units megabucks instead of megajoules) The codes allow engineers to provide (alternates to DTC) in the way of Modelling simulations/analysis/engineering Bim and Building surveys have to certify them. Your problem will be the builder has no interest in reducing costs as it reduces his profits. OT, On difficult and complicated builds it's always advisable to have your own certified engineering modelling data. Then get 3 builders to quote, when a builder comes back and tries to burn you (excuse the pun) with additional cost loadings (megabucks) ask for the engineered data and certified proofs (megajoule's).

I don’t know the properties of the double glazing. I will check out the roller shutters. Thank you. Thanks Doozer 1905 look to the link.
