  We consider the thermodynamic properties of the quasi-two-dimensional
spin-half Heisenberg ferromagnet on the stacked square and the stacked kagom\'e
lattices by using the spin-rotation-invariant Green's function method. We
calculate the critical temperature $T_C$, the uniform static susceptibility
$\chi$, the correlation lengths $\xi_\nu$ and the magnetization $M$ and
investigate the short-range order above $T_C$. We find that $T_C$ and $M$ at
$T>0$ are smaller for the stacked kagom\'e lattice which we attribute to
frustration effects becoming relevant at finite temperatures.
