INTRODUCTION:
Roof insulation is also a crucial element to achieve a cooler roof. Reective roof materials and insulation complete themselves in most climates.
When installing an insulation, to attain maximum energy savings, consider also attic and ceiling insulation. Insulation isn't only crucial to get lower heating bills. It's also important to reduce air- conditioning needs. However, the efciency o an insulation also depends on the manner on how they are installed.

made two model houses of the same si7e. he height,
the width and the length were made constant for the
two. !luminum foil-foam is used as an insulator for both
samples. &owever, the position of the insulator is
varied for it is the target of the research. 8or model !,
the insulator is placed at a distance of 99 cm from the
roof. he insulator for model ), on the other hand, is
placed in direct contact after the roof. Room
thermometers "one for each model# were used to ta6e
temperature readings at a :;-minute interval time.

COM!ARATI"E ANALYSIS:
compared to that of ). he mean for each model serves
as one of the proof. /ince model ! recorded lower
temperatures with respect to time, it only means that it
is more resistant to heat compared to that of model ).
%n the other hand, the /@ for model ! is higher and
this only means that the data gathered are really varied
from each other. hus, there is a LO# probability that
the result is only due to chance.
