Types of loft insulation.
Most efficient roof insulation.
In the past most homes used simple fiberglass insulated rolls.
Choose this option for areas that need a good amount of strength and water resistance.
Attics generally require an r value of r 35 to r 45.
The higher the r value the better the thermal performance of the insulation.
Also called styrofoam insulation this is the least expensive material.
R value is a measure of insulation s ability to resist heat traveling through it.
Box out light fixtures.
The table below shows what levels of insulation are cost effective for different climates and locations in the home.
It creates a breeding ground for mold and mildew and ruins the air trapping pockets that block heat flow.
This roof type can be much more expensive to implement than other efficient roof options so you should carefully assess your property and consult a professional before deciding to install a green roof.
Another way towards an energy efficient roof is added insulation.

These days you have options like spray foam foil faced reflective paper polyethylene bubbles or straw core panels.
There are many factors to consider and every one of them can make a difference in how much money you spend.
This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.
Green roofs also provide insulation lower the need for heating and cooling and can reduce the urban heat island effect.
An energy efficient roof can do a lot of good things for your facility but it can t do all the work itself.
Insulation level are specified by r value.
Water is insulation s enemy.
