Glass block is a attractive architectural detail, frequently discovered in bathrooms as home windows or shower partitions. It is a quite durable and lower upkeep item that diffuses mild and provides benefit to any dwelling. A single of the ideal utilizes is as a window in a shower or above a tub, where by privateness is necessary, yet light is ideal.
I have set up countless numbers of windows and showers in the last seven a long time in Florida, and have seen quite a few puzzling occurrences. Enable me reiterate that of the hundreds of installs, I have only viewed a handful of challenges, and have been equipped to effortlessly remedy them. The pursuing are my favourite:
This appears like a opaque or difficult to see by way of block, compared with individuals all around it. Often moisture can be noticed condensed inside. The cause is simple. Glass block is formed by casting molten glass into two types, then sealing all those two sorts together, producing a single block. Throughout the sealing process, the block is ordinarily vacuum sealed, avoiding dampness to get into the block. At times the seal is not comprehensive, or in some cases motion once set up will break the seal, which lets air (and humidity) into the block. This dampness will sooner or later fog and condense on the glass. The only solution is to take away and swap the block, greatest done by a hammer and a chisel (with eye safety) or even greater, decide up the telephone and retain the services of a specialist!
Black places within the black
A further final result of the sealing procedure is the occasional existence of ash inside the vacuum sealed block. This seems like black matter, and is not mould! This is harmless, and the most effective remedy is to ignore it! If it really bothers you, get rid of the block as directed previously mentioned.
Spider lines on the inside of of the block deal with
These are birthmarks that outcome from the heating and cooling of the glass. The finest remedy in this scenario is also to overlook them, or, if it definitely bothers you, have them eliminated as directed.
Leaking grout joints
This is a significantly troublesome prevalence, as you will definitely working experience water functioning down the block, and from time to time pooling. There are a number of prospects in this situation.
- The 1st and most benign is that the dampness in the air is condensing on the window. Grout is a cementacious merchandise, which is porous by nature. While glass block mortar does have a waterproofing agent existing, humidity will in some cases come as a result of the grout. If the moisture is current irrespective of rain or wind, and results in faint white streaks functioning down the glass, easy condensation is possibly your problem. Buy a grout sealer and seal the grout on the two sides of the window.
- The 2nd chance is a broken seal in the grout or a badly mortared window (the joint may well have mortar on the inside and outdoors, nevertheless be empty in the center, providing minor make any difference to block the h2o from wicking inside of). This is generally found in occasions of large rain, or rain from a distinct direction. The grout requires to be lower back again with a 4″ electric grinder, packed entire with mortar, and regrouted. Seal as indicated earlier mentioned.
- The 3rd and most challenging to take care of choice is that of a leak someplace else in the residence, that is discovering its way out via the glass block window’s porous joints. Very first, this leak have to be detected, which can be finished by visual inspection, h2o take a look at (with a hose spray water continually on the aspect of the home) or a dampness meter. A great mildew remediation company can do the water exam and will have a humidity meter if you have to have aid. Factors to seem for–cracks in the stucco previously mentioned the window. Voids in the stucco banding or joints earlier mentioned the window. Holes the place two stucco beads or bands come jointly. Roof junctures that have no flashing powering the stucco or siding substance. A good house inspector can take care of these problems. Observe that this previous difficulty has absolutely nothing to do with the glass block, and requires to be resolved at the supply of the leak.
Mysterious cracking glass block
This is my favorite, since it is so unconventional. You are asleep in the center of the evening and you hear breaking glass. You lookup the home and find that your glass block window is cracked. Or you go to just take a shower and discover broken glass in the floor of the shower, only to find that your glass block window is damaged! As time goes by much more and more cracks seem and glass blocks crack. I fixed rather a couple of of these just before I realized what was taking place (as a disclaimer, I did not do the initial set up!) The initial installer made the decision to conserve a couple of pounds and forego working with glass block panel anchors as directed by the producer. Rather he applied thick roofing straps. At some point these straps rusted, which brought about them to extend in the mortar joint. Something experienced to give to accommodate the enlargement. Mortar has terrific compressive strengh, and is dense in composition, so it had no home to spare. The only other solution was the glass, which ultimately gave less than the continual and increasing stress of the increasing metallic. Remarkable that rusting metallic can split glass!
As you carry on to resolving any of these concerns, be sure to be watchful! Removing glass block is cumbersome, and perilous. Often dress in eye security, and be recommended that it is incredibly hard to eliminate one particular block without breaking the 1 future to it. Clear all damaged glass meticulously, to avoid upcoming damage. It would possibly be properly really worth a number of pounds to hire a specialist to both inspect or take care of any of these problems, as this is outside of the essential household routine maintenance job.
Do not allow any of these troubles dissuade you from employing glass block. As you will observe, most of these problems can be prevented by using an knowledgeable installer who follows manufacturer’s guidelines.
