As the area is familiar with the white stuff, snow, Long Island can reach low temperatures. Hypothermia is not a good idea, so keeping warm is a must. There are a number of ways to achieve optimum warmth, a heater, a lit fire place, massive amounts of blankets, or even insulating. This can be cost effective, even for flat roofs, and your local Long Island roofing contractors can provide the service. They can install the protection and make sure that it works like a charm. But before choosing the right type, one must know the difference from the three most common types. And this article aims to help.

The blown flat roof insulation

This is also known as the loose-fill. This type costs more than other types, but generally provides better results. It reduces air leakage and fills in spaces and gaps much easier. The process involves using special equipment to blow fiber pellets or loose fibers into the building cavities or attics. Cellulose fiber is also an option as it can be installed in the attic with the use of a dry-pack process or a moist-spray technique. The cellulose fiber is treated chemically for resistance to moisture and fire. Blown insulation has a value of R-3 to R-4, which experts use as categories for the thickness. The bigger the number, the better.

Blanket insulation for flat roofs

This is also referred to as the batt and blanket. The latter is generally the cheapest type, but it requires careful set up to acquire effective results. The blanket comes in long rolls, while batts come in lengths of 4 or 8 feet. They are cut to fit in between wood-framings in the ceiling, within walls, or even the floors below. This type is made from mineral fiber, processed from either fiberglass, or rock wool. The batt and blanket are R-3 in the R-scale for thickness.

The rigid flat roof insulation

The rigid or rigid board to some, is typically used for flat roofs. This type  can be installed in the interior or exterior aspects. In the interior perspective, it must be covered with either ½ inch gypsum board, or with another building-code, fire safe and approved material. In the exterior aspect, the covering must be weather proof. This type of  is made from fiberglass, polystyrene, or polyurethane. It’s R-value varies and provides high insulation, ranging from R-4 to R-8.
