Single stack of Glass blocks as side light for entrance

I have a 93/4" wide space (2/4" framed) next to a new entry door and would like to use a single stack of 8/8 glass blocks as a sidelight. What misc. supplies and tools do I need? How much space will be left to be filled in with wood? Do you have another suggestion for filling the space? Thank you
Asked by: Alex
If you use the ProVantage II Installation, you r/o width should be 8-1/4" - that leave you with 1-1/2." You could trim out with 1x's on both sides and that would bring you to 8-1/4." In addition to the glass blocks, you will need ProVantage Vertical Spacers (use as Horizontal Spacers), Expansion Strips (cut to 7-1/2" and use between the glass blocks and sides), ProVantage Anchors, Pittsburgh Corning Glass Block Sealant, ProVantage Glass Block Surface Grout (if finishing joints with grout. you can use either grout or glass block sealant to finish the joints), Grout sealer if finishing joints with grout, 1-1/2" Flat Head Stainless Steel Screws - 2/anchor.

is the spacing adjustable? What is minimum/maximum? This is for shower application

Asked by: Rick
The mortar spacers create a 1/4" joint. The maximum recommended mortar joint is 5/8" and the minimum is 1/8." for a joint size other than 1/4", you could create your own spacer or free lay the blocks.

White Glass Block Mortar Spacers (48-Pack) is rated 4.3 out of 5 by 3.
Rated 4 out of 5 by from Glass Block Mortar Spacers work really well These little guys will allow a novice to install glass blocks like a pro. They insure uniformity in the mortar joints. My only problem was when I needed to break off the horizontal legs to use them as end of row spacers. The verticals have a weakened spot to allow them to snap off easily, the horizontals don't have that. I ended up cutting them off with diagonal cutters and smoothing them with a bench grinder. A little more work, but they all worked great in the end and the glass block window looks professional. These seem to me to be a little expensive for what they are, but it's the only game in town.

Rated 4 out of 5 by from Good spacers Spacers work as advertised. Docked one star because I think it should be a 50 pack - two of the plastic spacers broke before installation therefore I only got 46 usable spacers from one pack. Free HD delivery is nice.
