How Technique Behind Wall Insulation Westchester County New York
by William Barnes
Cavity Wall insulation is mainly used to overcome the problem of cavity in the walls. Cavity is the air gap between the two layers of brickwork which was introduced to stop the water from coming inside the house through the walls. But these cavities do not prevent air to pass through the walls and enter the house. That causes problems such as your house gets cool in winter season and warm in the summer season due to air passing through these cavities. That's why <a href="http://discountinsulation.com/services.html">wall insulation Westchester County New York</a> is used to fill up these cavities and other gaps in your house form where unnecessary air can come to your house.
Because there is no gap inside the solid partitions, the heat escapes very quickly through them. This requires a longer time to warm the house and therefore, more gas emissions and more money spent on heating bills. Actually, through a solid brick wall, the heat escapes twice as fast than it does through a cavity partition, which means that insulating them will save twice more money than cavity partition insulation (according to the Energy Saving Trust, an average size gas heated UK property can save up to 475 pounds per year by insulating the solid walls).
Firstly what is a cavity wall? Most properties built after 1930's are built with cavities. It's a process of building an outer wall separated by a gap (the cavity) from an inner one. The two partitions are tied together with partition ties. The reason why cavities were brought in was to separate the two partitions, as the older solid partition properties could sometimes transmit damp across the partitions because it was one continuous mass.
Your attic is a big source of heat loss from home and is one of the easiest places to get in to. Just insulate it properly and you can save a lot of energy. Lots of heat loses through the spaces around windows and doors. So these parts should be insulated properly.
The majority of properties built after 1930 are suitable, but you must have a survey done to check it for suitability. Make sure that your survey provides you with all the following information. The property must be of standard construction with the two walls built of one of these 3 types; Brick and brick, Brick and block and lastly, Block and block (these houses usually have a rendered finish).
External protection is done by fixing protection layers to the barriers with mechanical fixings and adhesive and covering them up with render or cladding. Similar to internal insulation there will still be necessary to remove some other parts such as pipes, fittings or extending window sills or roof overhang. Before insulating externally, any problems with rising or penetrating damp must be fixed first.
Before insulating, the cavity must be clean. A boroscope inspection of the cavity will provide this information. In addition, there must be no building defects that may affect the effectiveness of the installation. There must be no evidence of rising damp or penetrating damp. Black mould on walls is often mistaken for penetration damp. This problem is caused by moisture landing on cold partitions and CWI may help to alleviate this. Your survey should identify what type of damp you have.
R-value is a measure of quality of any insulating material. It measures its capability to prevent free flow of heat and air from outside to inside the house. The protection can be applied to many areas of house such as outside walls of your house, Top of the house etc. Be sure to check out on the above points whenever in need of this protection.
