The isolation and design to reduce heat loss

Roof Heating TapesThe isolation and design to reduce heat loss

Solar orientation

In North America, the ideal orientation of a house is to have next to those most exposed in the window on the south-southwest. This ideal is assumed that the area is adequately protected from westerly winds, or trees or topography of the area. If the house is protected from westerly winds, and the houses of the south are ideal. There are three main considerations for passive solar heating during the construction of a house, have the orientation,sun protection and surface finish.

The address of a house with a south-south-west, we can expect solar gains in winter to 550 BTU per square foot of surface area of ​​windows facing south for maximum sunshine hours (about 1:00-15: 00). However, always protect yourself from the sun during the summer months when heat gain of more than 1500 hours are possible Btu.

Designers tend to use any of the following shadingmethods. First, planting deciduous shade trees about 20 'of the south wall of the house, which is full of leaves in the summer and block the sun while putting the leaves in the winter sun that can come from the windows of the south. The second method is to use an eave or overhang. This projection, as a rule, should be about 2.5 times less in width, the height of the window, including the header (the radius for the opening of the window) tois exceptional. This will give adequate protection shade during the summer months when the sun arcs high in the sky in winter, when the arc of the sun is much closer horizon.

The exterior finish will also have an impact on building capacity to absorb and retain heat. Although small, you should try to stay within a coating of brick or rough surface, a darker color. This way, the exterior walls to absorb radiation instead of justreflect increase in temperature enough to help reduce the rate of heat transfer through the walls. Internal finishes should be smooth and light colored to reflect radiant heat in the room as possible. Avoid matte paint, if possible. The same is true for mounting on panels with the use of colored lights and ceilings, dark, smooth interior.

And if you want to take the solar gain in the end, could also be regarded as the form of the soil profile in the southnext, a cup-shaped dish, so that the reflected sunlight, bouncing on the surface of the snow in winter, concentrated in the south windows.

Vapor barrier

We use two types of membrane barriers in the modern construction, the air barrier and vapor barrier.

The air barrier is located outside the walls are wooden. Attics, for now, do not require the use of one. This includes the outsidebasement walls attached to the underside of the floor joists of houses built on stilts. It has two main functions. First, it acts to prevent the passage of free water from outside the isolated cavities in the wall or floor, causing structural wood, rot, and saturate the insulation. At the same time, the barrier allows the water in vapor form, which would otherwise remain trapped in the wall cavity to escape to the outside, which reduces the moistureconcentration of the components of the wall. A secondary objective of the air barrier to prevent the passage of air due to wind pressure or differential, that disperse the heat trapped in air pockets of insulation covered much faster. The air barrier can also increase the thermal resistance of the building, especially in R-2.

The vapor barrier is installed inside the insulation, and is used to delay the passage of water vapor enteringisolation areas. The steam is condensed, in turn, the insulation or structural components, insulation components and saturation of rotten wood. The vapor barrier is applied inside the building and is almost always installed as polyethylene (plastic), which come in rolls of 9 "wide and stapled in place. The joints between the plates are treated with a sealant or a superposition of two acoustic studies to ensure a permanent seal. hardening of the vapor barrier is sealedbetter, so it's a good idea to pay attention to all the joints, and any penetrations or holes.

One thing you might consider is the application of non-porous paints (oil based) for the interior trim, which play the same way that the vapor barrier, and add to its effectiveness. Caulking and sealing finish on the cards, like the floors and ceilings before applying the lining also adds to the overall effectiveness of the fence painted. Afinal note, I would not recommend the use of foreign materials such as plywood or aspen. These materials actually act as a vapor barrier on the surface of the outer wall, and holds moisture through the vapor barrier inside the wall cavity, where it condenses and the deterioration of structural components.

There are three main materials used as air barrier, which include saturated building paper, extruded foam board, and a new yarn product of sandpaper.

Saturatedconstruction works are mainly of paper, which is impregnated or saturated with tar or a similar substance, which makes it waterproof. It is usually in three or four feet wide rolls, which is clamped horizontally with a 6 "12" overlap. Of the three types is the cheapest and probably the oldest means of obstacles to outside air.

Extruded foam board is an ideal material because it can be used as insulation and act as an air barrier. Care should be taken in thisapproach to all joints should be sealed with tape to steam, which is quite expensive, but easy to apply.

Turn the sheet of glass fiber is a relatively new material (often called "sheet of paper"). These are mainly glass is rotated, in combination with other materials, then pressed to form a continuous sheet of paper. This type of barrier is a roll of width 9 "and is fairly easy to implement.

Isolation

Insulation works by trappingair pockets, which reduces the rate of heat transfer, reducing losses and carried by convection. The use of reflective materials such as sheets or smooth surfaces, bright colors also slow the loss of heat by radiation. It 'important to remember that you can only reduce the rate of loss, not eliminate it completely. Industry commonly measures the ability of the material to stop heat loss by reference to the "R value" or the value of resistance of materials. There are practical limits to the isolationand good design takes into account the recovery time that balances the cost of construction with a total energy savings. A good rule is to compare the total cost of adding insulation, which include the rising cost of structural components (eg, the wall, instead of 2×8 2×6) against time expect to live at home. What you should consider the rising cost of fuel used for heating equipment.

UsThree main types of insulation available today. They are spun fiberglass, rock wool, polystyrene, and urea-formaldehyde.

Yarns of glass fibers are most commonly produced in two types of mattresses or wires cut for installation in homes. Batt insulation is made of glass that is spun and woven his son in a thick layer of fibers of varying thickness, with an R value of about 3.2 cm thick. Chopped fiber insulation is basically the same blanket of insulation, but is overwrittenseparated in the plant and isolation in places like the horizontal roof or floor. It can be placed either by blowing crushed fibers from the pipe using mechanical equipment, bags or side, and then moves with a fork or similar tool. Blown glass fiber insulation provides an average R-value of about 2.6, while the casting and the spread of the thermal resistance is slightly higher R-3.1.

Rock wool insulation is similar to fiberglass except that it isstone rather than glass. It is available in two fiber networks and type of land covered with a better insulation R-value of 3.6 as glass, blowing the values ​​of R-2.9 and the position paid a total of R-3.2.

Expanded polystyrene insulation is one of the best available, but also one of the most expensive. There are three main types of extruded polystyrene, expanded polystyrene and polyurethane, or urea-formaldehyde. This type of insulation is ideal for areas whereexposed to moist conditions, such as foundations on the ground floor because they have insulation values, even when immersed in water. Similarly, polystyrene can be used effectively with a gust of fresh air required by the rules in Canada, and the joints are sealed with tape suitable for steaming.

Extruded polystyrene (often referred to as "foam board" or the trade name "Styrofoam") is usually blue or pink. Is done by pressing the foam expanded with a fresh moldIn fact, the extrusion through a model, or by injecting foam into molds individual. In general, the edges are designed to provide a block of continuous thermal break and help seal the joints between the panels. They are mostly in the leaves of 2'x8 'and offer a very high resistance values ​​of R-4.7 per inch of thickness.

Polystyrene foam (sometimes called "beadboard" or "cut-cell foam) is less expensive than the extruded foam board is usually whitecolor. It is composed of billets or pieces of foam, then cut into slices of varying thickness, usually without converging extruded polystyrene and joints. This type of foam board are normally made of "x8 sheets of different thicknesses '4 '. Unfortunately, the lack of values ​​of extruded polystyrene beadboard high-strength, with an average R-value of only 3.6.

The foam insulation is more expensive urea-formaldehyde orpolyurethane foams, which are placed by injection or spray expanding foam chemically cavities or on surfaces. This type of foam has been much controversy both in the gassing of chemicals in buildings, ands its lack of consistency in positioning. However, it offers the highest value of R is available for the foam insulation, which is only slightly higher than that of extruded polystyrene, with a resistance of R-4.8.

The simple design and the formulation of the walls

Roof Heating TapesThe simple design and the formulation of the walls

Development of the walls is known in construction as rough carpentry. This
always seemed a contradiction in terms. Framing
keeps the skin (drywall, coatings, coating) and buildings
lifelines passing through it (plumbing, electricity, heating, A / C,
telephone and cable). As the skeleton of a body, such as
framed walls of a house.

When installing the walls, you should pay attention to where
position. Finishes should be appliedconsidered in
mixture. If a party is to complete 12 'x 12' and finishing of the wall is 1 / 2 "
drywall, rough (there's that word again) the size
The walls must be 12'1 "x12'1".

The positioning of pivot wall must be considered. They can not be
placed anywhere. To understand the importance of this investment
That is, one must know the materials that are applied to the structure.
Building materials are commonly available in 4 x 8 sheets. These leaves
generally applyHorizontal, vertical, 4 and 8.
Available for the formulation of the common wall is 16 "centers. When set
out and well-framed, on the edge of the drywall or cover
stops in the middle of increments 4 places'.

The first step for installation on the wall to find two straight 2×4
and cut the length of the wall. Are you ready to
put pin. If your building perpendicular to an existing wall,
lay the 2×4 plates next to each other andRas ends. Hook
your tape on a plate and make your first sign
15 1 / 4 ". This is the tip of the first pin.
This puts the center of the beam 16 ". Continue at
the wall studs in the same way. The next would be
to 31 and 1 / 4 "and 47and1 / 4", then 63 and 1 / 4 "and so on.
at the center of the studs at 32 ", 48" and 64 ". Most of the bands
measures 16 "centers highlighted with a colorthis
easier. Once you have marked the position of your studies, the use of a square
(Or combination of speed) to draw a line across both plates. Put
"X" on the right of this line. This indicates that studies
itself.

If there are doors, windows or wall intersections
these are established first. Sixteen inch centers are presented below.
Openings of doors and windows can be moved from such studies amount or paralyze
is at the center line 16. This saves or eliminates aStud.

Coaching follows the same rules. Frame wall intersections first
and doors and windows. It can be difficult to frame these
elements if the wall studs are in the process.

Wall installation is a simple process and once you make a couple of times
See how easy it is. It will be even clearer
if you install the drywall or wall covering as well. It can be a
nightmare if the design is bad and the edges of

A certain amount of care and accuracy must not be taken to avoid

Kitchen Design Ideas – How to paint your old refrigerator

Roof Heating TapesKitchen Design Ideas – How to paint your old refrigerator

There are a couple of design and colors on the market for refrigerators. Most of us, just go for stainless steel refrigerators, because it can be inserted in a modern kitchen. But if you think of a better design and you want your refrigerator to look attractive, you can try to paint it.

Check out the following steps in painting your old fridge:

Step 1: If your current refrigerator installed on a wall or furniture, should not leave their place of paintingback. The back is usually painted black to help radiate heat coils. Just paint the front of the refrigerator.

Decide on the desired color. Buy the paint color you want. You can choose one with a glossy surface. There are also special types of paints that are used only for the team. The paint will not crack or dent, as they are designed to withstand extreme temperatures. If your refrigerator has been installed on a wall or furniture,choose the type of brush application of paint. Otherwise, you can choose the type of spray paint.

Step 2: Clean the outside of the front of your refrigerator. Dampen a clean cloth with water and soap and clean the exterior. Getting rid of oil, grease and stains. Then wipe the dust and dirt. Make sure the exterior is not fat so that paint can adhere to the surface of the cooler with ease.

Step 3: If there are scratches or chips, using soft sandpaper. Only the sand from the area and chipsnot around. Use a clean cloth to remove dust.

Step 4: Use tape to cover the handles of the refrigerator and on the sides. You can try to buy painter's tape because it is easier to peel. They also include the rubber gasket of the refrigerator. Also, instead of tape on the bottom front. This will prevent the paint goes in the refrigerator.

Step 5: Now you can paint the outside of the refrigerator. Be sure to follow a direction to get even coloring.Allow first coat to dry completely before adding a second. You can add a third level, if you want a darker tone.

Step 6: Allow to dry completely. Once dry, remove the tape.
