1. Foil-Faced THERMAFIBER Curtain Wall or FIRESPAN Insulation is mechanically attached to mullions and<br />
transoms using impaling pins, screws or other positive mechanical attachment.<br />
2. Exposed aluminum mullions must be protected with Foil-Faced THERMAFIBER Curtain Wall or FIRESPAN<br />
Insulation mullion covers.<br />
3. Safing insulation is compression fit (minimum 1/2� wider than opening) into safe-off area (2�- 8�)<br />
and supported with safing “Z” clips.<br />
4. A light steel angle or channel is placed horizontally at the safing line,attached to vertical mullions—<br />
either within the insulation at a horizontal splice,or behind the insulation and attached to vertical mullions.This<br />
detail prevents bowing of curtain wall insulation due to the compression fit of the safing<br />
insulation.<br />
5. Minimium 1� thick FIRECODE Compound installed over forming material (Safing Insulation) to form a<br />
tight smoke seal and effective thermal barrier.
