Saguenay, Terrace, Corner Brook, St. John’s, Prince Rupert

Out of the night the thunder rang in my ear.

I can’t fight the feelin’, Lord, that brings forth my fears.

I wish it was over, Lord, please stop the rain.

The rain that’s fallin’ on my window pane. (Grand Funk Railroad Lyrics)

Rain creates wetness and moisture making window treatment a two-pronged consideration involving the exterior as well as the interior of the home. Wetness is the direct result of falling rain and must be prevented from affecting the interior at any cost. Preventing rain from falling on the window pane is the easier than combating moisture. The best solution to protect windows from rain is to install awnings. For places like the five mentioned above with excessive rainfall, it may be a good idea to install fixed awnings made of durable material to help direct rain away from windows and also keep the ground below dry. For areas with moderate rainfall and a lot of sunshine, a better option will be a retractable awning that can be adjusted as required to reap the benefits of sunshine and light and prevent wetness and the detrimental effects of UV on expensive interior fittings.
When it comes to tackling the moisture content, indoors many factors come into play. High moisture content in the atmosphere generated by constant downpours must be prevented from entering indoors because a certain amount of moisture already exists indoors through internal water usage while washing, cooking and flushing.
In typical homes, air movement occurs through windows. Since warm air carries more moisture than cold air the moisture from outside should be prevented from increasing the moisture content of the already burdened internal air to saturation levels at which there is a real threat to surfaces and expensive interior fittings like carpets, curtains and upholstery on the one hand and the proliferation of bacteria, fungi, moulds, stains and dampness which in turn pose health risks to inhabitants through allergies, asthma and rheumatism.
The most obvious indication of the presence of excess moisture is the presence of condensation on the glass and other cold surfaces. Window treatments act as a barrier between the cold glass and the warm interior air. When the moisture laden warm air contacts the colder glazed surfaces, it deposits its moisture onto it resulting in condensation. Condensation on windows can be tackled through two approaches:
• Cover the windows with tightly sealed insulation that can be controlled from the inside.
• Concede that condensation will occur with traditional window treatment and prevent condensation by keeping the window treatment open whenever possible.
The material used in the treatment type will play an important role in moisture control. Blinds and shades made of material like polyester, PVC, Vinyl that are intrinsically resistant to humidity will be the best choice material for a window treatment in areas where there is heavy rainfall. For curtains and drapes always choose material that have been specially treated for moisture resistance.


Window Blinds

Blinds are available in aluminum, composite material, faux wood and vinyl all resistant to water and humidity. They can be customized to user requirements and can be made to provide a perfect fit for any window size. When fully closed they act as an effective barrier between cold window panes and the warm interior. Blinds made of these materials absorb the warmth present indoors and radiate it thus aiding in enhancing energy efficiency of the interiors.



Window Shades

Shades provide elegant window treatment solutions. Available in a variety of material they can be engineered to suit any requirement. Shades made of polyester fabric are very popular because they are attractive, wrinkle-free and moisture resistant. Available in cellular, sheer and pleated form, the fabric allows itself to be designed in many ways. They are available as roller shades, roman shades, bottom up top down shades, etc. They contribute towards thermal insulation, air tightness, cold comfort, condensation resistance, and ventilation. A clinching factor in favor of shades is the control mechanism options available which allow for synchronization with cutting edge technologies like virtual cord from Graber. Options include cord control, cordless lift or motorization.


Window Curtains and Drapes

Curtains and drapes are the most traditional window treatment types that have been in use since time immemorial. With the introduction of shades and blinds infused with rain and moisture resistance curtains and blinds face stiff competition as the de-facto window treatment solution in all climatic conditions. Curtains and blinds that have not been treated for moisture resistance may prove to be a liability rather than a protection for homes located in heavy rainfall areas.
There is a choice out there. Rain striking outside the window pane is a beautiful natural phenomenon that can be enjoyed with the right window treatment and most importantly the right frame of mind.
