Steel flashing with double kick is a clever design feature that protects wall cladding material from water penetration. This is achieved by directing dripping water sideways rather than vertically downward.

The kick portion at the end of the drip edge flashing is a crucial element in this design. It gently bends the sheet metal to ensure that water is directed away from the wall.

All parapet wall flashings offered by Northshore Sheet Metals come with a kick as standard. However, upon request, they can produce flashing without this element.

The use of a kick portion or a hem on the flashing makes no difference in terms of cost. Both types of flashing cost the same, regardless of the size of the items produced.

Parapet walls are constantly exposed to harsh weather conditions, and without proper protection, they can suffer severe damage over time. Water infiltration is a common issue that can lead to internal leaks, mold growth, and structural degradation.

Parapet wall coping acts as a shield, directing water away from the parapet wall and preventing it from seeping into the building materials. This protective barrier ensures that water is not able to penetrate the structure.

In colder climates, parapet wall coping helps to prevent freeze-thaw damage, which is caused when trapped water freezes and expands, causing cracks and other damage.

Coping helps to maintain the structural integrity of the parapet wall by covering its top and preventing water from seeping in and causing damage. This added strength is particularly important in regions prone to high winds or seismic activity, where structural integrity is highly important.

Securing the top of the wall helps to hold the materials together, preventing movement and shifting that could compromise the wall’s stability.

Parapet wall coping can significantly enhance the aesthetic appeal of a building, adding a polished and refined look to its structure.

The top of a parapet wall can often appear unfinished or plain, but with the addition of well-designed coping, it gains a refined look that contributes to the overall architectural harmony.
