Effective home insulation and draught-proofing are critical in minimising heat loss and maximising energy efficiency in homes. These strategies reduce heating bills and enhance the comfort of your family. We have written more about the benefits of home insulation.

Loft Insulation

Loft insulation acts as a barrier to heat flow, keeping homes warmer in the winter and cooler in the summer. A well-insulated loft can significantly reduce the amount of heat escaping through the roof. Industry standards suggest a thickness of at least 270mm for loft insulation materials, such as mineral wool, cellulose, or natural materials like sheep’s wool.

Cavity Wall Insulation

Cavity wall insulation fills the gap between the inner and outer layers of external walls, reducing heat loss. The different types of wall insulation can involve injecting insulating materials, such as polystyrene beads or urea-formaldehyde foam, into the cavity space. Homes with cavity wall insulation can save on heating costs and decrease energy consumption.

Draught-Proofing Techniques

Draught-proofing involves stopping unwanted gaps in the fabric of a building where cold air can enter and warm air can escape. Simple techniques include:

  • Installing self-adhesive foam strips around windows and doors.
  • Using silicone sealant for gaps in floorboards and skirting boards.
  • Applying draught excluders or brushes to letterboxes and keyholes.

Implementing these measures can lead to cost savings on fuel bills and contribute to a more energy-efficient home.

What is Air Tightness?

Air tightness is a critical component in constructing energy efficient homes. It involves the minimisation of uncontrolled air leakage through gaps and cracks in the building fabric. This reduces heat loss and enhances the overall thermal performance of the building, leading to a warmer and more cost-effective environment.

Importance of Air Tightness

An air tight structure contributes to:

  • Improved Thermal Comfort: Ensures consistent temperatures throughout.
  • Energy Savings: Reduced heating requirements due to less heat loss.
  • Moisture Control: Limits the potential for damp and mould growth.

Achieving Air Tightness

  • Identify the Air Barrier: Determine which layer of the building envelope will serve as the air tight barrier.
  • Simplify Design: Minimise the number of junctions and seams which must be sealed.
  • Quality Materials: Utilise materials like DuPont™ Tyvek® and AirGuard® to achieve a superior seal.
  • Consistent Workmanship: Meticulous application of sealing techniques is pivotal.

Measuring Air Tightness

Air tightness is quantified using an air permeability test, generally expressed in cubic metres per hour per square metre of the building at a reference pressure differential.

In conclusion, meticulous planning, high-quality materials, and skilled workmanship are key to achieving air tightness in self-builds, yielding a home that’s both energy efficient and comfortable.
