Standard Secondary Glazing Glass

4mm clear float glass is the standard for all secondary windows except Tilt In Balanced Vertical Sliders, for which the standard is 4mm clear float toughened safety glass - to comply with Safety Glazing requirements.

In both cases, good secondary glazing thermal insulation is created as well as some acoustic benefit, but not as much as would be gained by specifying Low E or sound proof glass.

Secondary Glazing Glass Options

The following patterned, obscure, safety, thermal and acoustic glass & glazing options are also available, where:

H - Denotes Heat/Thermal Insulation Glass

S - Denotes Safety Glass

N - Denotes Noise Insulation/Sound Proof Acoustic Glass

O - Denotes Obscure or Patterned Glass

For obscure, textured & etched glass options, please see the Pilkington Brochure pdf

About Us

Obscure Sandblasted Glass, Secondary Glazing London

By choosing the correct glass for your individual requirements, we can produce:

  • thermal secondary glazing the equal of replacement double glazing
  • sound proof glass acoustic windows
  • or an excellent combination of the two requirements!

As we are also General Glass Merchants and Glaziers, we stock and can obtain other specialist glasses - but please note that they may not be suitable for the secondary glazing range.

We also replace and re-glaze existing windows, so can fit acoustic double glazing and acoustic glazing if that is your preference.


In line with our policy of continuous product improvement & development Secondary Glazing London reserves the right to alter any of the product specifications without notice.
