June was a key date for our industry
This is the month that trickle vents became compulsory for installation for all new windows including general replacement ( not just new-build )
This was part of the revision to building regulations that were passed by Government during the early part of the year.
The Industry lobbied hard NOT for this to happen – customer feedback shows they are really unpopular .
They discolour , look unsightly, easy to break , drafty, let in outside fumes and pollution and there is a cost.
The main reason for the change was to allow airflow
Some cynical people may argue that consumers are paying extra now anyway for heat retention glass – and this effect is almost negated by the trickle vent – you may also ask how can a window be an “A” rated window with a trickle vent – the answer to this is easy – the authorities ( like the BFRC ) pretend it is not there !! – you tell me !!
