Windows and how to insulate them for winter
A window is an opening in a wall, door, roof or vehicle that allows the
passage of light, sound, and air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.
The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt, in Alexandria ca. 100 AD.
Step 1: Insulation in General
Insulation is a vast concept and is used in buildings all over the world to make a better comfort in your house and to prevent heat from being lost very quickly.The most vulnerable parts of a house in general are:
Thermal insulation in buildings is an important factor in achieving thermal comfort for its occupants.
Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. It does not necessarily deal with issues of adequate ventilation and may or may not affect the level of sound insulation. In a narrow sense insulation can just refer to the insulation materials employed to slow heat loss, such as: cellulose, glass wool, rock wool, polystyrene, urethane foam, vermiculite, perlite, wood fibre, plant fibre (cannabis, flax, cotton, cork, etc.), recycled cotton denim, plant straw, animal fibre (sheep's wool), cement, and earth or soil, Reflective Insulation (also known as Radiant Barrier) but it can also involve a range of designs and techniques to address the main modes of heat transfer - conduction, radiation and convection materials. Many of the materials in this list deal with heat conduction and convection by the simple expedient of trapping large amounts of air (or other gas) in a way that results in a material that employs the low thermal conductivity of small pockets of gas, rather than the much higher conductivity of typical solids. (A similar gas-trapping principle is used in animal hair, down feathers, and in air-containing insulating fabrics).
Step 2: Simple Windows Insulation System
If there is a solution for the rest of the house what about the windows nobody thinks about the open air pockets called windows, i will show you how to insulate the last remaining problem of your house windows insulation for winter.For this project, we will use common household item cheap, affordable and easy to make ok so let's get started with what we need to insulate the windows:
Step 3: Bubble Wrap Insulation
After we have prepared all the necessary things(you might have them already in your house) let's proceed to clean the windows, measure the bubble wrap and cut it accordingly, we will prepare the windows by spraying all over with plain tap water.After we have sprayed the area we will add the bubble wrap with the bubbles facing us and the flat surface to the windows that are prepared to be insulated, then gently remove the air pockets and look if is straight and it has no wrinkles.
Step 4: Windows Film Insulation Kit
There is also a special film for insulating the windows
Convection control film A film is attached to the window frame to trap a pocket of air between the glass and the film, creating a double-glazed system with an insulating gap of still air. Thermal conductivity of still air is 0.024 W/m/K and much lower than that of glass (0.96 W/m/K). Factors which limit the performance of a double glazed window are gap width, convection within the cavity and radiative heat transfer across the gap which is largely independent of its width. Optimal gap width depends on the temperature difference imposed across the gap. A European standard (EN 673) uses 20 °C difference between the inside and outside temperature which results in an optimal simulated gap width of about 17 mm for a standard double glazed window. A US standard (NFRC) uses a 39 °C difference which yields a smaller optimal gap width of about 13 mm. Using the European standard a window with an ideal gap of 17 mm has a simulated U-Value of about 2.8 W/m²/K, a window with a much smaller gap of 6 mm has a U-value of about 3.3 W/m²/K, while a single glazed window has a U-value of about 5.5 W/m²/K.
