Additional Information

This is a long form text area designed for your content that you can fill up with as many words as your heart desires. You can write articles, long mission statements, company policies, executive profiles, company awards/distinctions, office locations, shareholder reports, whitepapers, media mentions and other pieces of content that don’t fit into a shorter, more succinct space. Articles – Good topics for articles include anything related to your company – recent changes to operations, the latest company softball game – or the industry you’re in. General business trends (think national and even international) are great article fodder, too. Mission statements – You can tell a lot about a company by its mission statement. Don’t have one? Now might be a good time to create one and post it here. A good mission statement tells you what drives a company to do what it does. Company policies – Are there company policies that are particularly important to your business? Perhaps your unlimited paternity/maternity leave policy has endeared you to employees across the company. This is a good place to talk about that. Executive profiles – A company is only as strong as its executive leadership. This is a good place to show off who’s occupying the corner offices. Write a nice bio about each executive that includes what they do, how long they’ve been at it, and what got them to where they are.

Quality Standard Features

WACI blinds are made with .008″ thick slats on 1″ blinds, and .006″ thick slats on 5/8″ blinds. 

All slats are finished with an organic primer and a baked-on enamel finish coat. This finish is designed to withstand 500 hours of exposure to 100% relative humidity and 300 hours at 20% salt spray weathering without blistering, fading or corroding.

Our extruded aluminum rails are much more rigid than conventional thin rolled steel rails and they can be installed using our convenient snap-in mounting clips. Extruded aluminum is also less prone to corrosion in the extreme environment created between glass.

All WACI blinds are designed to operate using flexible cables constructed of brass or bronze coated high tensile strength steel wire wound in four layers to an outside diameter of .130”. Blinds can be installed using brass fittings and stainless steel set screws on the ends of the cables, or fiberglass reinforced nylon fittings which are injection molded directly onto the flex cables. If the injection molded nylon fittings are used, the jamb rods can be installed without the use of set screws.


1″ blind requires a minimum airspace of 1-1/8″ 

5/8″ blind requires a minimum airspace of only 3/4″


1″ blind uses a more resilient slat that is .008″ thick 5/8″ blind uses a slat that is .006″ thick 


Due to the thinner slats, the 5/8″ blind is easier to look through in the open position


1″ blinds will exhibit slightly better shading coefficient characteristics.
