§ Sir David Price
asked the Secretary of State for Transport what are his current criteria for determining whether householders living near a new stretch of motorway are eligible for double glazing; and if he will make a statement.
§ Mr. Peter Bottomley
The criteria applying to dwellings near a new motorway are those in the Noise Insulation Regulations 1975. Regulation 3 requires that traffic noise at a facade of a property shall rise by at least ldB(A) to 68dB(A) or more and that noise from the new highway shall contribute at least IdB(A) to the overall increase.
I am sending my hon. Friend a copy of a booklet which explains the position in more detail.
