Regulating heat loss/gain more efficiently
Insulating buildings like residential houses, buildings, factories, and offices is the most financially attractive of all energy efficiency and renewable energy measures to reduce greenhouse gas emissions. Insulated buildings reduce the need for additional power generation capacity by “smoothing out” the peaks in energy demand.
A poorly insulated building will result in room temperature inconsistency which requires vast amounts of energy to maintain a consistent ambient temperature all year round. Building insulation includes both ceiling and wall applications plus insulation to equipment. Insulation effectiveness is rated by its R-value which is a measure of thermal resistance within a building. Thermal resistance is a heat property and a measure of a temperature difference by which an object or material resists a heat flow (heat per time unit or thermal resistance). The greater the R-value, the better performance from the product in retaining heat in winter and expelling heat in summer.
A well-insulated building can go a long way in improving the thermal comfort for its guests and staff by regulating heat loss or gain more efficiently. The majority of heat loss takes place through the roof. A well-insulated building reduces reliance on the use of artificial heating and cooling systems, making the hospitality environment healthier, cheaper and more eco-friendly for guests. There are various products available, some of which offer additional sound and fire insulation. Insulating your building is a great way of reducing the burden of future increases in energy costs. There are various insulation products and applications available to suite the type and design of the roof and walls of your building.
The four main forms of insulation include:
- Pre-cut Batts or Insulation Blankets: there is a wide range available which are typically supplied in roll form and then cut to size.
- Lose Fill Insulation: this is pumped or spread over the roof area to take the form of roof cavities or spaces.
- Rigid Insulation: is supplied in pre-cut boards which are placed next to one another over the roof area.
- Reflective Foil Insulation has an aluminium surface which reflects and retards heat transmission. This is system is more effective in summer than winter.
