Insight On Loft Insulation
According to research, 25% of heat loss from non-insulated homes occurs through the roof. Therefore, homeowners should consider loft insulation as an investment that reduces their electrical expenses and improves their homes’ value. Loft insulation prevents the rising of hot air from other rooms below the attic by forming a barrier. Henceforth, the insulation traps warm air in the loft and inhibits its escape into the environment.
Advantages Of Loft Insulation
Apart from benefiting from the government’s grants when purchasing insulation equipment or seeking an installer, loft insulators decrease your heating and cooling needs. Subsequently, the electricity and gas costs will reduce after installing lofts in your roof since the generated heat in your house will not escape through the attic. Additionally, the process decreases the utilization of carbon to produce energy, thereby protecting the environment.
Loft insulation will improve your home’s comfort during extreme temperature conditions, ensuring your summer stays cooler and winter are warmer. Additionally, insulators can reduce the amount of noise entering your loft from the surrounding environment.
Types Of Loft Insulation Available
Location and the R-values are two key factors that one should use to select the best kind of loft insulation available in the market. Some of the loft installation techniques in the market require you to hire a certified installer while others need one to follow a set of directions to achieve recommended fitting.
Blankets, concrete block insulation, rigid foam, insulating concrete forms, blow-fill, blow-in, fiber insulation, and reflective systems comprise the existing kinds of insulation. The materials used include foam blocks, plastic films, bubbles, cardboard, and fibreglass. Additionally, one can use mineral wool, polyurethane phenolic, liquid foam, polyisocyanurate, cementitious, and plastic fibres.
The Installation Process
In case you have a plan to utilize the space in the loft for storage, you should use the joists’ board to achieve insulation. Place the boards on top of the joists before insulating the area to achieve the recommended thickness.
Additionally, you can install mineral wool at the floor to raise its level from the ground through placing timber battens that provide support. Allow ventilation between the boards and the insulation material to avoid condensate forming underneath the insulators.
You can hire a professional installer that will spray foam insulation on your roof’s sloping timbers since the technique ensures the space is warmer than typical loft insulation. However, rafter insulation is more expensive compared to other kinds of average insulation.
Additionally, it requires the separate insulation of chimneys and party walls to avoid heat loss. In case you plan to use the loft as a living area, you must hire a professional to insulate the walls and the ceilings appropriately.
For inaccessible spaces in the attic, a professional can use polyurethane foam, treated cellulose, or mineral wool to achieve the thickness recommended for appropriate insulation. The correct insulation of a flat roof occurs by placing rigid boards over the weatherproof layer.
Moreover, avoid underneath flat roof insulation because it causes condensation issues. Furthermore, one should strictly adhere to the building regulations when installing loft insulation in their home.
