What Thickness Insulation For Floors

Insulation level are specified by r value.

What thickness insulation for floors. Stylite eps floor insulation is available in a range of different thicknesses and sizes. Fiberglass r 19 batt insulation is about 6 inches thick and is available in 15 inch widths making it the correct size for insulating a two by eight floor joist system. Stylite eps floor insulation boards. Interior wood framed floor insulation.

Encapsulating the floor system including duct work with thermo cloth and closed cell spray foam insulation creates a perfect wood framed floor system. Insulation is rated by its r value. The inside of the rim joist is sprayed from the sub floor to the bottom of the rim joist to drop the building envelope to the bottom of the joists. The higher the r value the better the thermal performance of the insulation.

In general the insulation s method of installation can give you an idea of how it compares to other types of insulation. Many builders will baulk at this figure it was not long ago that installing 50mm of insulation in the floor was considered fairly advanced. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. A higher insulation r value usually means a higher price point as well.

Floor insulation can cut your heating bills keep your home warmer and block draughts. In this scenario a rigid foam insulation is usual and as you d want the same u value in the roof we need the same thickness of insulation 180mm. The insulation should press right up against the floor between joists. R value is a measure of insulation s ability to resist heat traveling through it.

The table below shows what levels of insulation are cost effective for different climates and locations in the home. R value measures how resistant types of insulation are to heat flow. R values vary based on the type thickness and density of the insulation material. Stylite have created the eps range of insulation boards specifically for floor insulation and can be used with any floor substrate in a wide range of applications from domestic to industrial flooring.

Rockwool offers stone wool insulation products to meet and exceed thermal regulations in floor constructions as well as solutions for separating floors to prevent heat transfer between the upper and lower floors. The fiberglass will also need to be secured in place using wire mesh twine wood laths or other securing methods which can be an intensive project that adds to the overall cost.
