Roof Insulation – Aerolite and Isotherm

Roof insulation, such as aerolite and isotherm, becomes the barrier to heat flow between the shingles and the roof and prevents heat from passing through, keeping you cooler in the summer and warmer in the winter. Homes that have been well-designed and insulated with compliant insulation will keep you comfortable year-round and cut the cost of heating and cooling your home by nearly half, which in turn reduces greenhouse gas emissions. greenhouse effect.

Weather conditions will also influence the proper level and thickness needed for your installation. You will need to establish if you are trying to keep heat in, out, or both. Roof insulations are effective against daily and seasonal temperature changes.

Another important factor is the technical design. If roof insulation is installed in a location that does not have shade or curtains thick enough to block morning and afternoon sun, it could have the reverse effect, heat coming in through windows or doors can be trapped inside and create an oven effect.

Moisture problems such as condensation can be eliminated by installing reflective ceiling insulation and can help protect your home or office from the elements. Aerolite and Isotherm ceiling insulation also have excellent sound-absorbing properties and are good for soundproofing a room or office. It is best to install roof insulation during construction, new building regulations state that all new homes must be insulated and meet a curtain R-value to comply.

Roofs, floors, and ceilings have a small thermal resistance by themselves, but not enough to meet building laws sans 10400-xa

Different climate zones require different R-values ​​needed to comply with building laws sans 10400-xa

When choosing the right roof insulation, there are two main categories to choose from: reflective or bulk insulation. In order to obtain an even greater insulating effect, reflective and bulk insulations are often combined. Examples of blended insulation would be factorylite, which is aerolite combined with reflective insulation, or isofoil, which is isothermal combined with reflective insulation. The R-value of the product determines the ability of the product to resist heat flow. The higher the R-value, the better insulating effect you will get from the product.
bulk insulation

Bulk insulation is excellent at resisting convective and conductive heat. Heat is trapped in pockets within the insulation structure. The thermal resistor works the same way, and it doesn’t matter which way the heat flows through it. Bulk insulation and reflective insulation are the two types of insulation currently on the market. The main bulk insulations are pink aerolite, which is a glass wool product, and isothermal roof insulation, which is a polyester material. Bulk insulation comes with an R-Value that differs depending on how thick of insulation you need.

45% can be saved in cooling and heating energy with roof and ceiling insulation
20% additional cooling and heating energy with bulk wall insulation
5% off winter costs with the proper floor insulation used in your home

Radiant heat flow is resisted by insulation with reflective properties, this is achieved because the insulation is highly reflective and its ability to re-radiate heat. There is a 25mm air layer on which the reflective insulation is based next to the glossy surface. Heat flows differently through reflective insulation depending on which direction the heat source is coming from.

Glossy aluminum foil that is laminated to paper or plastic is how reflective foil insulation is made. The performance of reflective insulation can be affected by dust that settles on it over time. Dust reduces its reflectivity. The shiny foil surface should always face downwards. The anti-glare surface of the single-sided sheet must always face up or out.

R values ​​up and down are supplied with reflective insulation. The R-value of products will differ depending on how and where the insulation is installed. Always make sure that the values ​​given by the manufacturer relate to what you are looking for.

When installing any type of ceiling insulation, you should avoid leaving gaps. Even the smallest gap in roof insulation can decrease the value of the insulation. Roof insulation must fit snugly between joists and there must be no gaps around ducts and pipes. Seams and holes in the reflective insulation must be properly sealed and even plugged if necessary. A lot of heat can leak through ceilings, floors, and walls, so make sure these areas are properly insulated. When installing roof insulation, there are minimal clearances that need to be left around objects like transformers and downlights because overheating can cause a roof problem.

Wall insulation should fit snugly around door and window frames and, in very cold locations, have thermal breaks around metal frames to reduce heat loss. The internal walls of a house or those used more often in offices must be properly insulated, this will also soundproof the room and produce less echo.

Never compress bulk roof insulation! This reduces the insulating ability of the roof to adequately insulate. Tiny air spaces within the roof insulation trap hot air. Sufficient space is needed for the roof insulation to maintain its thickness. Vapor barriers, such as sisalization or spunsulation, must be used to keep moisture away from bulk roof insulation, or it could decrease the insulation performance of the products. Use reflective vapor barriers for roof insulation where condensation may occur.

Loose-fill roof insulation should not be used on a roof with a slope of 25 degrees or more. Because it is loose and not coiled like a meteorite or isotherm, it cannot maintain its thickness at angles. Roof insulation in roll form is the best route to insulating your home or office, as the installed material can maintain its constant thickness and not reduce R-values ​​in curtain areas, regardless of slopes and high winds that They can loosen the insulation. your roof Remember that loose-fill roof insulation will settle by up to 25 percent over a period of time reducing its original thickness.
