| PERFECT FITTING IN
REINFORCED CONCRETE |
 |
The unit is
supported at the points A, B, C, D, being trapezoidal in shape like
the keystone of an arch. |
| GREATER
RESISTANCE AGAINST BENDING & EXPANSION |
 |
Under
the strain of longitudinal compression in grooved units the
normal components move to the outside, causing risk of breakage
(excessive overloading or appearance of expansion). In "Novalux"
units the normal components move to the inside, i.e.,
towards the body of the unit. |
 |
BETTER
USE OF THE WORKABLE HEIGHT OF THE UNIT—
INCREASED SECURITY
For the first time, thanks to the
"Novalux" units, it is possible to place the upper and lower
rods in the best manner, i.e., as near as possible to
the surface of the framework, and this without risk of touching
the glass. The whole workable height of the framework can thus
be used, allowing heavier loading and larger capacity.

| FACILITIES
OF RENEWAL |
BEFORE
When a unit was accidentally broken many delicate and
expensive operations were necessary to replace it:—
1. The cutting out of the joint of the total depth, thereby risking
breaking near-by units.
2. The necessity of shuttering trouble and expense of scaffolding.
|
TO-DAY
To change a "Novalux" unit it is sufficient to:—
1. After having released the damaged unit by breaking it, chip out
corner A of the concrete in the upper part only.
2. Fit the new unit into opening thus made, first painting with
white lead from point C to base to ensure waterproofing.
