Notice that you don t see insulation filling all the spaces between the ceiling joists.
What is the best material to use for roof insulation.
Batts or blanket insulation.
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.
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.
In general the larger the r value the more effective the insulating material is.
Here are a few of the most common insulation solutions available.
R value is a measure of thermal resistance or resistance to the flow of heat of an insulator.
The best insulation for your home will depend on the situation and if you are replacing or supplementing existing insulation.
These days there is such an extensive range of roof insulation materials it is difficult to make a choice.
Batts or blanket insulation are the best choice for ceiling insulation if you have a flat ceiling and pitched metal or tile roof.
What insulating materials are suitable for roof insulation.
R values vary based on the type thickness and density of the insulation material.
Three types of heat loss or gain.
You can generally compare roof insulation material performance using their r value ratings.
You apply this insulation by spraying a solution in the floor walls or ceiling causing a bubble up into a thick layer of insulation.
R value measures how resistant types of insulation are to heat flow.
Loose insulation fiberglass or recycled fiber materials.
Other insulation materials include foam wool and even insulated glass for windows.
Batts are about the worst you can do here.
They may use mineral wool fibre treated cellulose or polyurethane foam.
We will list the different products their possibilities and insulation values for you.
See that photo above.
The range of batts and blankets that may be suitable for ceiling insulation include.
Insulation is rated by its r value.
For the best performance an insulation material needs to fill the whole space with no gaps voids compression or incompletely filled areas.
Polyester natural wool glass wool and rockwool.
Use hardware cloth metal flashing or scrap plywood to create a safety gap of at least 3 inches all around fixtures.
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.
A flat roof should preferably be insulated from above.
