If you live on a busy road, acoustic glass -specified as part of a replacement window solution - can make a real difference. A laminated glass that incorporates polyvinyl butyral resin (pvb) is added to the outer face of the double glazed unit - and this significantly reduces noise levels.
Laminated glass is also very tough - so gives your property an extra level of security.
Acoustic laminate option adds £120 to the price of a sash window - and we’re finding this is an increasingly popular choice (our last job, in leamington - and our next job, in Nuneaton - both have acoustic specified).
