Glass — How to Buy It

A homeowner can get a lot for his money or a little when he buys glass for windows, doors or dividers.

Window glass, also called linen glass, is the most commonly used in the house. In fact before glass walls and picture windows were used it was usually the only kind. It comes in two thicknesses, single strength and double strength; and in two qualities, A and B.

Grades A and B differ only in the number of small flaws and ocean. However, the difference is not in most cases noticeable, and many dealers don’t even stock A quality because they don’t believe that it is worth a a quarter premium.

Whether to use single or double strength depends mainly on window size. A good rule to follow is with double strength for anything over about two feet sq. What size can double strength glass be? If years don’t exceed 60 to 70 michael. p. they would., double strength glass may be used in sizes up to 38″x48″, or 34″x72″.

The next price jump to very linen or plate glass is very sharp. If you want a window wall consider the likelihood of working it out using the indicated dimensions of double strength instead of plate glass. This can be most attractive and at about one-fourth the cost. Go right across the room with 30″x72″ double-strength glass placed vertically. The space of approximately 30″ to the floor can be plain wall or used for built-in bookcases, cabinets or ventilating louvers.

Case Lots

Buying window glass by the case is one way to save money. Glass by the case doesn’t cost much more than half as much as by the linen. It’s also safer to handle. At economical prices you can afford to use glass liberally in whatever you decide and build or remodel or enclose. And, buying by the case does not mean you’re stockpiling it for years into the future. Usually a case of window glass is whatever number of sheets comes nearest to totaling 50 sq feet. Cases of very big sheets contain 100 sq feet.

Very linen, which is heavy window glass of good quality, is the economical thing to buy when the opening is too big for double strength.

Plate glass, which is finished to optical efficiency, may be 1/8″ thick or for a big view window, 1/4″ thick. If you have a long-distance view through your window, you will need plate glass. Otherwise you can use very linen; for short miles you will not notice the slight waviness.

For plate and usually very linen, in sizes too big for you to handle and too costly for you to risk breaking, you must figure on paying a higher installed price, which includes a costly labor cost.

Heat-absorbing plate glass, while no substitute for ac, does screen out approximately 29% of the sun’s heat. It is used in western side windows of seaside homes, as well as in car windows. It costs about 5/2 times as much as regular plate glass.

Unknown glass is used where you want light but no visibility. For example, a wall of it might be just the thing for a cellar recreation room where the main cellar is used as a garage or class. For this you would need the thick kind, say 3/8″. Thinner figured glass serves for entrance panels, filing cabinet doors and shower enclosures.

Transparent mirror glass is often used for one-way vision in entrance doors. Ready-made it is rather expensive, but a glass dealer who makes magnifying mirrors can usually prepare it for you at about half the price.

Insulating glass is the modern, superior replacement ordinary windows plus storm sash. Like any warmth, it usually pays for itself over the years in fuel savings as well as comfort. It consists of two or three window panes sealed in units, with air spaces between the window panes. A typical double glazed unit has two sheets of 1/4″ plate glass with a 1/2″ air space between. Originally all insulating units were made of plate glass, but it is now manufactured in window glass as well. If you do not need large windowpanes, you can save about one- third with the window glass kind.

Glass Blocks

In the long list of building materials, glass blocks rank as one of the most versatile. They can be used for exterior as well as interior walls or for partition walls that do not go entirely to the threshold.

Glass blocks provide light plus privacy. They come in many sizes and shapes and there are special blocks built to control the sun’s rays. Furthermore, glass blocks are easy to maintain and special units are available to provide setting up through glass block walls.

Glass blocks can be installed within a wooden frame or in a bed of mortar. Once you discover how to set class blocks in mortar — a project you might want to undertake to switch a pre-existing cellar window with glass blocks — then you will be able to handle glass blocks within a frame inside. Literature on interior mounting of glass blocks is readily available from glass block manufacturers.

How to work with Glass Block

The proper mortar materials and mix are important whether for laying bricks or glass blocks.

The proper mortar materials are Portland concrete floor, hydrated lime, sand, water, and waterproofing compound. The addition of an integral water-proofer of the water-repellent type is an added measure to insure water tight joints. Manufacturer’s specifications concerning the use of this material should be followed very closely. Where a waterproof masonry mortar is used, no additional water-proofer should be added to the mix. For better results, accelerators and antifreeze compounds should not be used.

ACCURATE RATING

The accurate rating of materials is important. Generally a 1-1-4 mortar mix is satisfactory. However, reasonable variations from the mix are permitted and permitted limits are covered by manufacturer’s specifications.

MORTAR CONSISTENCY

The consistency of the mortar mix has a direct having on the strength and weather-proof ness of the joints. Since glass blocks have no suction like bricks, the mortar must be drier… it should not flow or have too much suffering. Too wet a mixture makes it extremely difficult to get proper positioning of block joints, and cleaning time is greatly increased. The mix should he not too dry, not too wet, but just right. Here is a positive thing to remember: Do not re-temper mortar after the ¡niti. il set has had place.

PANELS OF GLASS BLOCK 35 SQ. LEGS. OR LESS

In this type of construction the most area is 35 sq feet with maximum width 5′ and height 7′. The practice is with an expansion space at the side jambs of all glass block panels. However, for small panels as highlighted here the blocks can be mortared in solid at the side jambs. It is necessary, however, to keep a finger space between stone withes about 3/4″ deep. This permits the mortar to input at jamb and secure panel.

Glass block panels, regardless of area or size, are nonload having and require space at the head to take care of expansion and lintel deflection.

PANELS OF GLASS BLOCK BETWEEN 25 AND 100 SQ. LEGS.

Where it is desirable to show the full face of the block panel, chases cannot be used for lateral support. Proper support can be had by using wall anchors if the area is not over 100 sq feet and neither panel dimension is over 10′. The wall anchors should be spread out 24″ apart — and occur in the same joint as the wall tie. To allow for free movement of the panel, the anchors are crimped or curved in the expansion space. As a space for calking must be provided, a standard expansion deprive is easily cut to 3″ width to be inserted between the anchors with gobs of asphalt emulsion. Local code authorities in some areas may restrict the use of wall spine construction.

Glass Cutter machine

This tool is used to cut glass to size. Usually, a glass cutter machine has a small rotary wheel or diamond occur the handle.

There are also glass cutting bits for drilling holes in glass. These special bits require the use of a lubrication while cutting. It is best to make a ‘well’ or ‘dish’ around the spot to be drilled by using putty to form the walls. Then put a little turpentine or oil into the ‘dish’ to lubricate the bit whilst it is cutting through the glass.
