What is a Rescheck? Quite simply it is a document that describes the overall efficiency of your insulation in your building. If it does not meet the overall efficiency that is required by the code,
it will fail and you will not get a building permit.
You should not even try to get a building permit if the minimum efficiency form requirements are not integrated into your specific plans. If your municipality does not require one, you still need to meet certain insulation requirements based on the regular building codes.
Windows and doors are rated on a different system than solid structures like walls and roofs. Their heat-resistance rating is measured by what is called a U-factor. Each individual brand of doors or windows will have their own U-factor value. All of these numbers need to be added into the res check software.
What is a Rescheck purpose? The rescheck form is a great timesaver for the local building inspector. He or she can look at this form, see the location, instantly see the square footages of the walls and roofs, compare that to the square footages of the doors and windows, and instantly see that the building meets or exceeds the necessary insulation requirements.
