The Importance Of A Correctly Insulated Loft
The insulation in your loft conversion has one primary function. To prevent heat exchange through the floor, walls and ceiling of your living space. In the winter this means less warm air escapes from your loft, and less cool air escapes during the hotter summer months. Significant cost saving due to the reduced amount of energy required for heating or cooling. A correctly insulated loft conversion is very important, as outlined in the info graphic below.
Types Of Loft Insulation
Blanket Loft Insulation
Blanket insulation is the most common and widely available type of insulation; it comes in the form of batts or rolls. It consists of flexible fibers, most commonly fiberglass. You also can find batts and rolls made from mineral (rock and slag) wool, plastic fibers, and natural fibers, such as cotton and sheep’s wool.
Loose Fill Loft Insulation
Loose-Fill and Blown-In Insulation. Loose-fill insulation consists of small particles of fiber, foam, or other materials. These small particles form an insulation material that can conform to any space without disturbing structures or finishes. Safety equipment and protective clothing worn.
Sheet Loft Insulation
Sheet insulation designed to insulate the sloping sides of the roof. Comes in the form of firm boards. Some sheet insulation boards are available with a fire-resistant, moisture-resistant or decorative covering.
Blown fibre loft insulation
Blown fibre loft insulation consists of small pieces of insulating material, blown into your loft with a hose and specialist tank, to mix the material with air so that it can be propelled it into the attic. Coverage is generally excellent with blown fibre insulation, and it’s far more ideal than traditional rolls of insulation for covering areas where access is difficult.
Keeping Your New Loft Conversion Insulation Compliant With Building Regulations
Modern building regulations currently stipulate that the u-value of the roof must be 0.18W/m2. U-value, also known as Thermal transmittance, measures transfer of heat through a structure, divided by the difference in temperature across that structure. The units of measurement are W/m²K. A u-value of 0.18W/m2 means a 270mm layer of wool or fibre insulation, 175mm of rigid board insulation or around 125mm of high performance spray foam. When Chelmsford City Loft Conversions are undertaking your project you can be sure that all these standards are being met.
