Using styrofoam in attic for insulation.

This is an even more dense and more expensive foam board insulation. Spray polyurethane foam will provide thermal insulation that will minimize air infiltration which can help to save on heating and cooling costs within the indoor environment. Earlier this year i got a question about a home that had spray foam insulation in the attic. It provides an r value of 6 per inch of thickness and often comes foil faced to help reflect radiant heat.

Step 4 cut foam boards. Remove the old. Nothing unusual about that. You can use a utility knife to cut using the same cut and snap process you use with drywall.

That styrofoam insulation will work but it is not cheap per r value however it gives you a great r value per inch. A table saw will also cut the board but it. A lot of builders and homeowners are going with spray foam insulation because of the airtightness benefits but then the questioner mentioned that the spray foam contractor had intentionally left big holes to the outside by not sealing the gable vents. Remove any existing pieces of insulation that might have been covering the attic walls until now.

Step 2 install insulation boards. Insulation is used in an attic for cross ventilation to minimize potential for moisture accumulation and condensation to help energy savings and moisture control. Use a chalk line or t square to mark where it needs to be cut. Insulating an attic usually means you have a lot of room for insulation and you will need high r value so that is why the cheaper options are more popular blown cellulose or blown fiberglass.
