Home Insulation And Reduced Heat Loss

Slide 2:

About Us An Overview of the Industry The industry of insulation materials have seen an evolution over a period of time. From being used in the packaging of various products with its application being put to use in industries as well as households, insulation materials have now come to be used in the construction purposes and that is where they have found their real value. Being able to reflect the heat and the cold that the nature has to offer, these sheets have managed to maintain a comfortable environment for people staying in very warm and equally cold areas.

Slide 3:

What is the Insulation? Insulation—silently hidden in your walls, no moving parts to fix—is a material you probably spend precious little time thinking about. Then along comes subzero (or sweltering!) weather, a three-digit utility bill or chilly drafts, and you start thinking about it a lot! At home, you ponder whether it’s worth the time and expense to add it to your ceilings, walls and basement. At the store, you ponder which type, thickness, width and density to buy. And when you install it, you wonder just how good is “good enough.” We asked insulation manufacturers and installers which questions they field most—and which blunders they see most. Following are six things they (and we) think you should know.

Slide 5:

Choosing Insulation Insulation products come in two main categories — bulk and reflective — which are sometimes combined into a composite material. For the many different products available see ‘Insulation types and their applications’ below. To compare the insulating ability of the products available, we need to look at their R-value, which measures resistance to heat flow. The higher the R-value, the higher the level of insulation. Products with the same R-value have the same insulating performance if installed as specified. Check the information supplied on the product, including the R-value, the price per square meter and whether it must be installed professionally or can be DIY — some types of insulation require the use of masks and protective clothing. Ensure that it suits your particular application and fits within the space available. Ask if performance guarantees or test certificates are available. All insulation materials that are sold in Australia must meet Australian Standard AS/NZS 4859, materials for the thermal insulation of buildings, even if they are imported. Compare the environmental benefits of different products.

Insulation Types A nd T heir A pplications Bulk insulation  mainly resists the transfer of conducted and convicted heat, relying on pockets of trapped air within its structure. Its thermal resistance is essentially the same regardless of the direction of heat flow through it. Bulk insulation includes materials such as glass wool, wool, cellulose fiber, polyester and polystyrene. All bulk insulation products come with one material R-value for a given thickness.

Slide 7:

Reflective insulation  mainly resists radiant heat flow due to its high reflectivity and low emissivity (ability to re-radiate heat). It relies on the presence of an air layer of at least 25mm next to the shiny surface. The thermal resistance of reflective insulation varies with the direction of heat flow through it. Reflective insulation is usually shiny aluminum foil laminated onto paper or plastic and is available as sheets (sarking), concertina-type batts and multi-cell batts. Together these products are known as reflective foil laminates, or RFL. Dust settling on the reflective surface greatly reduces performance. Face reflective surfaces downwards or keep them vertical. The anti-glare surface of single sided foil sarking should always face upwards or outwards.

Slide 8:

Where to install insulation Roofs and ceilings work in conjunction when it comes to insulation. Install insulation under the roofing material to reduce radiant heat gain. Install insulation in the ceiling to reduce heat gain and loss. In most cases ceiling insulation is installed between the joists (see Insulation installation). External walls should be insulated to reduce radiant, conducted and convicted heat transfer. Wall insulation can be installed: within cavities within stud frames on the outside of stud frames on the inside or outside of solid walls.

Slide 9:

Installation Increases The insulation’s R-value By Over 20 Percent The most important steps you can take: Fill the stud cavity from top to bottom and side to side. To avoid guesswork when insulating walls built from standard 92-5/8 in. long studs, purchase and install precut fiberglass batts that are 93 in. long and 15 in. wide. When you have to custom-cut batts at wall corners and other places, cut the batts 1 in. higher and wider than the cavity you’re filling. Split your insulation so half goes in front of and half goes behind electrical wires. Compressing insulation reduces its R-value. Around electrical boxes, notch, rather than compress, the batt —then tuck the cutout behind the box. To help prevent frozen pipes, insulate only on the cold side.

Slide 10:

How much insulation is enough? The high-density insulation on the right, with more fibers and air spaces, can deliver up to 35 percent more insulating value than standard insulation. The payback period for retrofitting insulation varies greatly, but studies show that added insulation usually pays for itself in saved energy costs within 5 to 10 years. In Minnesota, a typical payback period might be five or six years. Payback in more temperate areas takes longer, but remember that insulation reduces air conditioning costs too.
