A fire-resistant construction panel (10) includes a structural panel (12) as the web component of an l-joist (24) having an exposed surface (14) and a magnesium oxide board (18) covering the exposed surface (14). Alternately, the fire-resistant construction panel (10') includes a load-resistant magnesium oxide board (30) being a structural element as the web of an l-joist (24').
