Walid Mumuni hit a three-pointer soon after and some excellent play at both ends of the court meant Storm ended the quarter in front 24-16.
Crusaders scored the first seven points of the second period to reduce the lead to just a single point but two superb under pressure jump shots by centre Tom Adorian opened it back out to five at 28-23.
It was the turn of the three-point shooters to take over Storm’s scoring and following a pair of triples by Adeluola, another one by under-18 junior Jack Burnell swished through the net to a deafening roar from the crowd and Hemel opened a twelve point lead with just a minute to play in the half.
