With the climate changing and extreme weather becoming harsher, it is good to know James Hardie has a handle on these things. They examined the relationship between their fiber cement products and the eight climate factors affecting them.
Then they discovered common variables that allowed them to group the effect of climate in ten categories, and create two product varieties. This is why installers use their HZ10 products in the southern United States, to protect them from blistering sun, and hot humid conditions
Whereas we use the HZ5 variety in Vancouver because it resists shrinking, swelling, and cracking better, even after years of wet or freezing conditions. However, that’s just the beginning of a superior siding job. It also needs to go on properly.
The Effect of Climate and Wet Weather Continued
Next time someone tempts you with a cheaper siding job in wet season, choose your contractor carefully. Although James Hardie fibre cement products are weather resistant, they can not be left saturated in the rain for prolonged periods of time. For if they do not:
1… They become heavy when saturated, and more difficult to handle and fit properly.
2… They shrink when they dry, opening up joints between planks needing repair or replacement.
James Hardie recommends countering the effect of climate and wet weather, by covering unopened boxes with a waterproof tarp, and store the material on a pallet for ventilation. For if they become wet they are no use until they have dried out completely. We have standard procedures in place to protect raw materials from weathering.
Fibre Cement Is an Effective Barrier When Correctly Installed
Fibre cement is cement composite with cellulose fibre reinforcement, formed in boards, and cut to sizes and lengths. As a result, it resists termites, impact and rot, and has good fire-resistant properties too.
Fibre cement siding is also moisture resistant when overlapped correctly, and sealed at all open joints. Moreover, it should require very little maintenance assuming professional installation.
