My parents have recently had new windows fitted and external wall insulation on a 1920s terraced house.
There were previously no vents in the bedroom but these have now been drilled and covered with very cheap looking sliding plastic vent grills. Even when closed there is a noticeable draught and outside noise coming in through vents.
Their gut feeling is that they are losing more heat now than before the (expensive) work was done.
The bedrooms are centrally heated via a downstairs coal fire, so there is no "combustion" going on in the bedrooms. They had never had any issues with condensation or mould in the bedrooms despite the lack of vents.
Short of blocking up the vents entirely, what are their available options that are DIY \ relatively inexpensive that would help to address the draught \ noise ?
I suppose ideally they are looking for vents or solutions that when they need to be closed e.g. in wind, very cold weather, or noisy conditions - they are actually closed and stop all draughts and outside noise.
e.g. Would any of these 'core drill ventilators' be better? Could these be easily fitted by a handyman now that the vent 'hole' is in place?

Note: In seeking advice please do not quote building regulations to me. I'm looking for practical, helpful advice. If there is a reason why something should be done (or not done), explain the reason.
