DIY Window Mullion Grids, Step by Step
by Jill from The Rozy Dwelling

Hello everybody! It’s Jill from The Rozy Dwelling. I’ve labored for nearly 5 years (sure, 5 lengthy years) to make our home our ceaselessly dwelling. My most up-to-date mission is certainly one of my favorites so far. You see, I’ve acquired an AMAZING view. It’s simply spectacular – throughout the day. However at night time, when the view disappears, I’m left with two large, boring home windows in my eating room. I haven’t been 100% pleased with the home windows in my eating room for some time now, however I by no means knew what it was.

After which I had my ah ha second. I spotted that what bothered me is that each window on the entrance of the home (together with the arch home windows and even the little home windows) have grids however each window on the again and facet didn’t. At first I believed the builder did this as a result of he needed to benefit from the view. The extra I considered it, although, the extra I spotted he did it to be low-cost. I feel that if he actually needed to benefit from the view, he would have picked bigger home windows with out large pane dividers going by them.

With this in thoughts I made a decision so as to add my very own window grids. I shall be sincere with you – I didn’t know the place to begin. Naturally I took to the web and was so dissatisfied by what I discovered.  I discovered tutorials that both had been too sophisticated or seemed actually, actually low-cost. So I did what I usually do with initiatives – drank espresso and simply thought on it.

I walked round the home and seemed on the home windows with grids. Then I spotted the grids had been merely made up on two vertical items and 6 horizontal items. With that bit of information I headed to Dwelling Depot to seek out the proper trim.

Fast notice: conventional mullion grids as made by producers are skinny strips of aluminum between the panes of glass on a a double-pane window to make for simple cleansing and power effectivity. These DIY windowpane dividers are simply eliminated for cleansing the glass panes and saved me a bunch of cash by making my very own grilles and giving me the aesthetic attraction I needed. Owners who need the true architectural model of the window muntins grids can discuss to a window producer to retrofit or exchange their home windows.

Dividing the home windows into smaller panes of glass does barely scale back the quantity of pure mild within the room, however this DIY doesn’t impression the structural integrity of the window, so take into account your private style and make an knowledgeable choice about what you want to your home windows.

Step 1: Selecting the Mullion Grid Materials

Whereas at HD I checked out a ton of trim. I considered wooden. The one drawback is that the items on the entrance are usually not wooden in order that they wouldn’t match. After a little bit of looking out I got here up with these polystyrene vinyl display mouldings:

Not solely had been they the proper width, however at $2.38 for 8 ft, they had been the proper worth. My home windows are 32 inches broad and 72 inches tall and there are 4 complete so determined I wanted 16 items (which, by the best way, was an excessive amount of. Seems I solely wanted 12 items).

(Replace: I later traded for this pine display moulding trim, which is only a hair thinner, in order that my mullions didn’t rub on the window once I opened it.)

Step 2: Decide Mullion Grid Placement

Once I acquired dwelling the very first thing I did was resolve how broad aside I needed the vertical dividers. I made a decision on two vertical items of wooden that had been spaced about 10 1/4 inches aside. Subsequent I made a decision what number of horizontal items I needed. For that, I opted for 3 rows. Having figured that out, I measured the size from the highest of the window to the underside (simply the glass half).

I made these cuts and hooked up them to the window with double sided tape. This allowed me to precisely measure the size of the horizontal items. After figuring that out, I went and reduce 48 (sure 48!) horizontal items and the remaining vertical items.

Step 3: Paint Mullion Grid Items

After slicing the items, I took them out within the storage and spray painted the again. This wasn’t actually mandatory as a result of nobody will see the again of them, however I made a decision to “do it proper.”

Right here’s the factor about spray portray poly – it takes a minimum of three coats to cowl it. I used Rustoleum 2X and it nonetheless took 3 coats.

Step 4: Construct Mullion Grids

After deciding how far aside I needed every grid, I measured from the underside of the grid up and marked the spot.  I needed mine spaced 8 1/2 inches aside, so I measured 8 1/2 inches from the underside and marked it throughout your complete piece. It’s actually useful to put a horizontal stile on the backside between the vertical stiles. This helps guarantee your measurements are equal.

Subsequent, I took out the useful dandy sizzling glue gun and put sizzling glue on the tip of the horizontal stile and hooked up it to the vertical stile. Then I did the identical factor on the opposite finish (attaching it to the opposite vertical stile). It’s simpler to begin with the middle horizontal stiles first.  It’ll make the general construction extra steady.

Repeat the steps on the left and proper sides. Enable the grids to take a seat for about quarter-hour.

Step 6: Connect Mullion Grids to Home windows

To connect the grids to the home windows, I bought double-sided/mounting tape from Ace. I positioned one piece on the again of the highest of every vertical stile. On a couple of I hooked up them to the skin horizontal stiles. They stick actually, very well and in the event that they put on out they’re tremendous low-cost (and simple) to switch.
