Dean Bradley of Glazpart says the changes to Part F of the Building Regulations will make trickle vents the hardware that both fabricators and installers have to get their heads around – and use for an upsell.

Bradley writes, everyone in the window & door sector will be aware of the impending changes to the building regulations especially the requirement for trickle vents to be used on most new windows installed.

The lack of ventilation and the harm it does has been ignored by both installers and homeowners – and fabricators, of course. Add a lack of information and education and there has been little incentive or motivation to improve the environment in dwellings.

So the government has decided to act. Not only does poor ventilation damage the internal environment, it damages health. The NHS is aware that better ventilation could save it a small fortune.

The government’s view is that there is a need for regulation to address the issues informed in part by a study that shows that very few homes meet the current minimum ventilation provisions recommended in ADF 2010: 2006.

The government audited 55 sites for compliance to ADF and only 2 sites complied to the 2006 regulations.
