Energy Efficiency Factors: General Considerations
Energy efficiency is a critical aspect of sustainable development, aiming to reduce energy consumption in buildings, transportation, and industrial processes. Achieving this requires careful consideration of several factors related to building design, construction, and operation. Among these are thermal performance and insulation, air tightness, life cycle of materials, and recyclability and environmental impact.
Thermal performance and insulation
Thermal performance refers to the ability of a building envelope—the exterior walls, windows, doors, roof, and foundation—to manage the flow of heat in and out of the building. Good thermal performance reduces energy consumption by over 20% by maintaining a comfortable indoor temperature while minimizing the need for heating or cooling.
Effective insulation is a key aspect of good thermal performance. Insulating materials are installed to slow down the transfer of heat between the interior and exterior surfaces of a building. The ability of insulation materials to resist thermal conductivity is measured using their R-value or U-value. High-quality insulation with a high R-value or low U-value will ensure that heat is effectively retained in the winter and repelled in the summer, leading to significant energy savings.
There are various types of insulation materials available, each with different properties and applications. Common insulation materials include fiberglass, cellulose, mineral wool, foam board, and spray foam insulation.
Air tightness
Air tightness is the measure of how well a building prevents uncontrolled airflow between the interior and exterior. Air leaks in a building’s envelope can cause heat loss, negatively impacting thermal performance and resulting in energy wastage. An air barrier is necessary to restrict the flow of air through the building envelope, reducing heat transfer and air movement.
To ensure a high level of energy efficiency, it is essential to address air tightness both during the design and construction phases. Some strategies for achieving optimal air tightness include sealing gaps, using energy-efficient windows, and properly installing insulation materials to minimize thermal bridging.
Besides conserving energy, improving air tightness has other benefits, such as reducing drafts, enhancing indoor air quality, and protecting building components from moisture-related issues like dampness and mold growth.

Thermal conductivity of aluminium and uPVC
Thermal conductivity refers to the ability of a particular material to conduct heat. The lower the thermal conductivity, the better the insulating properties of the material. Aluminium has a high thermal conductivity due to its metallic nature, which makes it an efficient conductor of heat. This ability to conduct heat quickly can be a disadvantage in certain circumstances where you want to maintain a consistent indoor temperature irrespective of the outdoor temperature.
On the other hand, uPVC (unplasticized polyvinyl chloride) is a type of rigid and durable plastic that exhibits significantly lower thermal conductivity when compared to aluminium. Because of this, uPVC is considered an excellent insulator that efficiently prevents heat transfer between the indoors and outdoors. This results in a more stable indoor temperature and decreased dependency on heating and cooling systems, ultimately contributing to lower energy consumption and reduced energy bills.
Insulated glass units (IGUs) and their role in energy efficiency
An insulated glass unit (IGU) is a combination of two or more glass panes separated by a gas-filled space or vacuum, which is designed to reduce heat transfer across the window or door. IGUs are commonly found in double-glazed or triple-glazed windows and sliding doors. They play a vital role in improving the energy efficiency of a building by providing better insulation and reducing heat transfer through the glazing.
Both aluminium and uPVC sliding doors can be fitted with IGUs, which further enhances their insulating properties. The type of glass and the gas or vacuum between the panes will have a direct impact on the overall energy efficiency of the door. Additionally, the choice of the right type of spacer bars, seals, and the correct assembly of the IGUs is crucial in ensuring optimal thermal performance.
U-values and their impact on energy efficiency
U-values are a measure of the rate of heat transfer through a building material, expressed in watts per square meter Kelvin (W/m²K). A lower U-value represents better insulating properties of the material, resulting in reduced heat transfer and improved energy efficiency.
U-values are essential when comparing the thermal performance of different materials used in building construction, such as aluminium and uPVC sliding doors. For example, if a sliding door made from aluminium has a higher U-value than a similar sliding door made from uPVC, it means the aluminium one will allow more heat to pass through, resulting in higher energy consumption and higher energy bills.
