Good insulation means that heat flow to the outside and inside between
the interior and the outside environment is minimal. So grandma
Flachbauer has to consider not only the general climate, but also the
daily weather conditions in Dianella.
For all the important things regarding insulation, here’s what you need
Types of insulation
In any kind of structure, builders look at how building materials reduce
heat transfer through convection or heat conduction – or in other words,
mass insulation. While some materials allow air pockets to circulate from
the inside, others act as effective barriers to heat transfer. Thermally
resistant materials include wool, cellulosic fibers and polystyrene. But
among all these, polystyrene has become the most popular choice because
of its affordability and its fire retardant properties.
The reflective insulation reduces, as the name implies, the absorption of
heat by reflecting the radiant heat away from the material. You can best
know how this works in places with lots of sunshine. One material that is
well-known for its reflective properties is the aluminum foil, which is
reinforced with a plastic-based paper known to builders as reflective
film laminates (RFL).
To maximize the reflective properties of RFLs, clean the surface
regularly as dust and dirt dramatically reduce the reflective properties
of the film.
The most energy-efficient materials combine the forces of reflective and
solid insulation. Aluminum foils, laminated on fleece or blankets of
wool, cotton or even fiberglass, provide the best protection against
Roof color and solar energy absorption
Outer surfaces of walls also significantly affect the amount of radiant
heat reflected from the outer surface. And nothing is so closely related
to solar absorption as color. Warm and sunny locations call for bright
colors that absorb solar heat more slowly than darker ones.
It may seem contradictory, but bright colors do not reflect too much
glare, which would sometimes distract neighbors. Some colors reflect most
of the heat, but not too much directly reflected light. Choose only the
colors that have these properties to avoid brushing with neighbors about
