Top 4 Reasons to Insulate

As the summer ends and we face the coming autumn and winter, it's an ideal time to consider the thermal performance of your home. Uninsulated walls are responsible for around 35% of heat loss, while uninsulated roofs make up for another 25%. Insulation slows down both convective and conductive heat flow and there are many different types of insulation material available from Greengate's, your local builders merchant.

Insulating a property has many beneficial effects, including:

  • Improved Energy Efficiency. Heat will always naturally flow from warm spaces to cool, attempting to equalise the imbalance. This means that warm air from inside will try to leak to the outside and vice versa, processes that can be dramatically slowed down by insulation. The insulating material will reduce the air leakage of the property, cutting both heating and cooling bills by up to 50% and reducing carbon emissions.
  • Improved Thermal Comfort. By keeping the inside of a structure warm during cold weather and cool during the summer, insulation improves thermal comfort. Throughout the changing seasons, indoor temperature will be maintained at a pleasant, stable level.
  • Reduced Risk of Conden­sation. One of the most common causes of damp is conden­sation, which occurs when warm, moisture-laden air meets a cold surface such as a wall or window. By reducing temperature differences between the external and internal surfaces of walls and windows, insulation lowers the risk of conden­sation.
  • Reduced Risk of Mould. All air is naturally loaded with water vapour and, the warmer the air, the more vapour it can hold. This increase in humidity makes mould growth more likely, lowering the indoor air quality and even leading to health complaints. Insulation reduces the risk of mould growth by increasing the average surface temperature of walls.

A compre­hen­sive collection of insulation materials and ancillaries is available as part of the extensive Greengate's product portfolio. The range includes fibreglass, rigid, polystyrene, multifoil and fill insulation: discover more options on our website and get in touch with our expert technical team if you need help choosing the right material for the job.
