SOUND INSULATION

To obtain sucient sound insulation special requirements may be

necessary both in connection with choice of window variant and

with the installation (see also chapter 7, page 108).

REPLACEMENT OF WINDOWS

In some areas replacement windows come under the aspects of the

Building Regulations. This means that application must be made to

the Local Authorities before the work can commence.

FENSA registered companies can however carry out replace-

ment work immediately and then register the work with the Local

Authority on completion.

In all cases local planning requirements must be observed.
