What Is The Best Material To Use For Roof Insulation

In general the larger the r value the more effective the insulating material is.

What is the best material to use for roof insulation.

You can generally compare roof insulation material performance using their r value ratings. Unless you re using mineral wool insulation or your fixtures are rated safe for contact with any type of insulation don t allow the material to touch or cover recessed cans or lights from the floor below it s a fire hazard. For the best performance an insulation material needs to fill the whole space with no gaps voids compression or incompletely filled areas. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold.

They may use mineral wool fibre treated cellulose or polyurethane foam. See that photo above. Loose insulation fiberglass or recycled fiber materials. The range of batts and blankets that may be suitable for ceiling insulation include.

Batts or blanket insulation. Notice that you don t see insulation filling all the spaces between the ceiling joists. R values vary based on the type thickness and density of the insulation material. Some insulation and building materials are better at maintaining a stable temperature inside the home than others.

The best insulation for your home will depend on the situation and if you are replacing or supplementing existing insulation. Batts or blanket insulation are the best choice for ceiling insulation if you have a flat ceiling and pitched metal or tile roof. These days there is such an extensive range of roof insulation materials it is difficult to make a choice. The best roof insulation is blow in cellulose which is a form of bulk insulation that is environmentally friendly quality with a lifetime guarantee.

A flat roof should preferably be insulated from above. R value measures how resistant types of insulation are to heat flow. If your loft is hard to access you can have blown insulation installed by a professional who will use specialist equipment to blow appropriate insulation material into any awkward space. Use hardware cloth metal flashing or scrap plywood to create a safety gap of at least 3 inches all around fixtures.

You apply this insulation by spraying a solution in the floor walls or ceiling causing a bubble up into a thick layer of insulation. Here are a few of the most common insulation solutions available. Insulation is rated by its r value. R value is a measure of thermal resistance or resistance to the flow of heat of an insulator.

Polyester natural wool glass wool and rockwool. We will list the different products their possibilities and insulation values for you. Other insulation materials include foam wool and even insulated glass for windows. A relatively recent development in the world of insulation spray foam insulation is really quite effective and serves a great purpose that no other insulation truly can.
