Insulation level are specified by r value.

Choosing the right insulation type can vary depending on your needs and your desire to be green.
What s the most efficient roof insulation material.
Also called styrofoam insulation this is the least expensive material.
The higher the r value the better the thermal performance of the insulation.
Most homes are filled with traditional fiberglass material with newer ones adopting recycled cellulose material for more environmentally friendly alternatives.
Another way towards an energy efficient roof is added insulation.
Green roofs also provide insulation lower the need for heating and cooling and can reduce the urban heat island effect.
Types of loft insulation.
The table below shows what levels of insulation are cost effective for different climates and locations in the home.
Insulation for energy efficiency.
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.
Look for water stains on the roof sheathing or damp or moldy spots on attic joists and existing insulation as a clue to where leaks might be.
It creates a breeding ground for mold and mildew and ruins the air trapping pockets that block heat flow.
There are many factors to consider and every one of them can make a difference in how much money you spend.
1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them.
