In addition to it's well known range of fire glasses which offer integrity, integrity with radiation control and partial insulation, CGI International now introduce a new, fully insulated product, Paraflam, to complete its matrix of glasses for various performances and time periods.

Paraflam is manufactured by an unique process which forms a clear, salt-based gel layer between the outer leafs of fully tempered glass. Depending on the gel layer thickness, fire resistance and insulation periods can be provided from 30 minutes to over 120 minutes. Paraflam is factory-made to specific sizes up to a manufacturing maximum of 1500mm x 3500mm but should be used within the size parameters of the test date (please see Paraflam Certification page).

Properties

In the event of a fire the gel layer within the Paraflam makeup will react to form a fire and heat resistant layer. Dependent on the gel layer thickness, resistance times from 30 minutes upwards can be achieved as follows:

Features

Paraflam offers a number of performance features over multi-layer insulating glasses including:

  • high level of sound reduction achieved by the thick, absorbent layer.
  • visual clarity is not affected by multiple glass discolouration, green-ness. High light transmission circa 50%.
  • in higher fire grades, much lighter weight is achieved over glass multi-layers due to thinner glass content.
  • can be easily incorporated into a double glazing unit to provide thermal or solar performance.
  • interlayers can only be reacted by fire temperatures, not by climatic conditions.
  • robust, fully tempered outerlayers mean less chance of accidental breakage.
  • operating temperature range - 20C - +50C.
  • gel layer is UV stable and can be used externally or internally.

Fire and Impact Performance

Fire testing has been carried out to BS 476 Parts 20 & 22 by UK test houses. Also in other European countries to the equivalent test standards which are similar or related to ISO834.

All Paraflam panels will achieve Class A impact rating to BS 6206, due to the outer leaves being fully tempered glass.

Typical Frame Details

Paraflam has been tested and approved in a wide variety of approved frame types, some of these are depicted below for general information.

These details show some of the typical frame styles in which Paraflam has been specifically tested or assessed by CGI International. Other frame styles can also be used provided CGII, a frame system maker or others hold the relevant certification/approvals.
