Add ?" to sum of the nominal block sizes for both the height and width. Example: panel (using 8"x8" block) is four block wide and five block high. Rough opening needs to be 32-1/4" wide and 40-1/4" high. All mortar joints are 1/4" wide. Assumes a ?" mortar joint will be used. Multiply the number of glass blocks by the nominal size (4", 6", or 8"), and then add to that sum an extra 1/2". Apply this formula to determine both the width and height of the opening.

Mortar One is for panels 25 square feet or less which are enclosed on all four sides by Pittsburgh Corning Perimeter Channels. Mortar Two is for panels larger than 25 square feet or for panels not supported on all four sides. This system uses panel reinforcing and panel anchors to tie the block together and to the surrounding structure.

For standard size new construction windows, usually 1 " under the nominal size of the window, which will allow 1/4" clearance all around. For example, for a 4030 XO window, make the RO 47" X 35". If you order a custom sized (heel dimension must be stated) window, the window will be the heel dimension ordered, so you will need to make the rough opening that size PLUS whatever clearance you wish, usually 1/4" all around.

The same size as your door. The door fits against the opening from the inside. The opening should be finished with an exterior perimeter seal or stop molding to seal against the elements.

For single doors, as a general rule, add 2" in width and 2-1/2" in height to the nominal door size for single doors. For instance, a standard 3/0 x 6/8 door would require a 38" x 82-1/2" rough opening. Pairs would require twice the nominal door width plus 2" as well as an additional 1/2" if there is an astragal ( between them. For example, a standard pair of 3/0 x 6/8 doors with an astragal would require a 74-1/2" x 82-1/2" rough opening.

Eight 8d common nails (See Figure 5) should be driven through the rectangular box (stair frame) into the rough frame to help hold the stair in place temporarily while positioning the stair as in step 4 of the instructions. When used properly, the size screws and nails suggested are best.

For all prehung units we REQUIRE that you provide us with your rough opening size. We will build the unit to fit the rough opening size that is provided. If this is for new construction, we normally add 2" to the height of the door and a total of 2" to the width of the door for a rough opening. This allows for the thickness of the jamb and leaves an extra 1/2? in width and height to square the unit.

Obviously, you want to avoid the kind of damage described above, and in order to accurately recreate the original mortar you typically have to have the mortar analyzed. Although a building constructed before 1871 was undoubtedly pointed with lime mortar (because portland cement wasn't even available until that year) the years after 1871 are a grey area.

In 4 foot (trough to crest) very steep waves as long as you have wind, she’ll reach and run with very little roll. (If anyone starts to turn a little green, get them out of the cabin, eyes focused on horizon, and don’t read, it should pass in a few minutes, if not gone too far). Close-hauled in 4 foot waves some spray will reach the cockpit but you can duck behind the raised pop-top (with dodger installed) to stay dry.

Hydraulic lime mortar is a lime mortar that hardens in damp or even wet conditions through a chemical reaction rather than exposure to air. (This is in contrast to standard, or non-hydraulic lime mortars, which harden by absorbing carbon dioxide, a process known as carbonation.) Hydraulic qualities are created when clay is included in the lime mixture.

Yes. We are familiar with computer system security and can advise you about the security required and help you implement appropriate safeguards.

Two factors should be considered when choosing the "Rite Size": The opening height and the Order of Architecture that is desired. Simply divide the opening height (in inches) by 7, 8, 9, or 10 (depending on the desired Order of Architecture). The result is the "Rite Size" or architecturally correct column diameter for the opening height. Column diameters are in inches and vary from 8" and up in 2" increments.

Even though Zanfel is safe on damaged skin, excessive scrubbing with this or any other product is not recommended. Remember that the goal is to remove the urushiol oil, and this usually takes no more than 15 seconds of scrubbing. In fact, Zanfel also deep cleans the skin, promoting fast healing of the wound at the same time it is removing the toxin. Zanfel feels good when you scrub with it, even on cuts.

We travel in protected areas most of the time. On many days of the summer this coast is like sailing on a lake - flat and calm. Sometimes we cross into open water for short periods of time where we may experience greater motion.

You are certainly welcome to send me a potential thesis or a rough outline for feedback from me. I'm happy to look at these over email or in person. If you have a rough draft completed, I will look over it if time allows, and my schedule changes from week to week. My feedback will concentrate on argument and structure. I'm unlikely to give you concrete "do this" suggestions-rather I try to identify areas that might be improved.

Spalled brick in an1860s lighthouse that was repointed with portland cement mortar about twenty years ago. The historic stone masonry units have deteriorated dramatically, while the portland cement mortar joints remain intact. It' s important to understand that historic buildings are very different than modern buildings in several key ways: First, historic brick--in particular--is softer than modern brick because modern brick is fired at a much higher temperature than was possible in the past.

Colored mortar that matches or complements the Marble Face Polished /Ground Face colors can create a beautiful effect. For more information on mortars see Mortars in the GENERAL information sheets in our product literature. W.R. Grace DRY-BLOCK® is recommended for all exterior mortar.

If you are interested in integrating one or more of The WERCS® modules with your existing business system, then The Wercs Ltd.'s consultants are trained with real world experience to provide integration services for the interfaces such as formulation, inventory and order entry.

We're very happy to look at works in progress, and may be able to make suggestions that will be helpful to you. We're also willing to comment on treatments or proposals. We'll be glad to discuss this with you at any time, but we can be more helpful and specific if we've seen your film first, so that we have a better idea of its potential audience.
