Precast Fire Rated Glass Blocks

Our partner,Glass Block Technology,Precast Fire rated panels are manufactured in accordance with the glass block manufacturers test & certification data.

Different fire rating requirements mean variations in construction
of the panels from the blocks used, quantity of vertical & horizontal stainless steel reinforcement to joint sizes or border widths.

Panels can be manufactured in single or connecting pieces dependent on the size required and should be restrained in place ideally with steel.

BORDERS AND CLAMPS
Precast Concrete Fire Rated Panels are always manufactured with perimeter borders as a requirement under fire certification and also designed to assist with clamping panels in place as shown.

EXPANSION FIBRE

Expansion material is crucial for fire rated panels. This example depicts a 60/30 panel which requires a minimum 20mm perimeter expansion joint. Mineral fibre can be used or two lengths of GBT 10mm expansion foam doubled up (head and jambs). 2 No. bitumen strips to the base also siliconed over in a fire Stop silicon.

ARCHITRAVE

Where the precast panel meets the perimeter opening, the join has been decoratively finished by an architrave moulding.
