Sheet metal roofs are a quick, inexpensive, and easy-to-build alternative. However, if you do not have good insulation, they can make your environment and your lovely property very noisy, hot in summer, and too cold in winter. Have a consultation with a metal roof specialist.
Insulation of a sheet metal roof
If your tin roofs are not insulated, summer can turn them into a real oven and winter, into a refrigerator. You are going to spend a fortune on heating and air conditioning! In addition, the noise caused by hail and rain can become such an annoying problem that, in some cases, they prevent conversations and listening to the radio or television. Therefore, isolation is a critical step.
Types of roofing sheets
Galvanized sheets and Cincalum
They are available with diverse thicknesses, 30mm, and 40mm, 50mm, and in diverse smooth, waves, trapezoidal and sinusoidal. The stimulated sheet material use to be removed from cold or hot rolled steel, coated with a layer of zinc.
Cincalum sheet is an alloy of aluminum and zinc, with a formula of 55% aluminum, 1.6% silicon, and balance zinc. This combination offers greater confrontation to corrosion, compared to galvanized ones, they have a longer service life of up to 5 times. Visually it has a crystalline appearance resulting from the combination of aluminum with zinc.
The plastic sheets are made of polyester resins with fiberglass in coils. They use to be covered on both sides by a 20gr meter per square polyester surface. This provides resistance to the elements.
Sheet steel galvanized or zinc alloy coated can be available with the option of prepainted. This means that an anticorrosive coating is applied to them and then a layer of polyester enamel, silicone, or fluorocarbon polyester. This system offers additional sturdiness against atmospheric agents that is able to affect the valuable life of the sheet.
