Heatwaves are no longer exceptional events. Every summer, extreme temperatures affect an increasing number of sectors, with livestock farming among the most exposed.
A recent report by La Sexta highlighted how many livestock farms in Galicia are installing climate control systems to combat heat stress in animals. The reason is clear: during periods of intense heat, a dairy cow can produce up to eight litres less milk per day, while the risk of lameness, reproductive disorders and even abortions also increases.
In response, fans, misting systems and other cooling solutions have become essential allies for many farms. However, one important question often goes unnoticed: what happens if heat continues to enter the building through the roof and external walls?
This is where thermal insulation plays a key role.
The Impact of Heat Stress on Livestock Farms
Livestock perform best within a thermal comfort range that allows them to maintain their welfare without additional physiological stress.
When this limit is exceeded, animals prioritise regulating their body temperature over milk production, weight gain and reproductive performance.
The most common consequences include:
- Reduced milk production.
- Lower feed intake.
- Reduced fertility.
- Increased health problems.
- Higher mortality under extreme conditions.
- Increased energy consumption across the facility.
The increasing frequency of extreme heat events has accelerated the adoption of climate control solutions on livestock farms. Industrial fans, misting systems and ventilation equipment are now common features in many facilities, helping to reduce indoor temperatures and maintain more favourable environmental conditions for livestock.
Climate Control Systems: An Essential Response to Heat
Cooling systems are essential for maintaining suitable environmental conditions inside livestock buildings.
However, they all face the same challenge: if the building continuously absorbs heat, the equipment must operate for longer periods and consume more energy to maintain the desired temperature.
For this reason, specialists increasingly agree that the most effective strategy is to combine two complementary approaches:
- reducing heat gain through effective thermal insulation;
- maintaining optimal indoor conditions using climate control systems.
These two solutions do not compete with one another; they complement each other.
The Importance of Thermal Insulation for Livestock Farms
The roof is one of the main areas through which heat enters a livestock building during the summer.
When solar radiation strikes the roof for prolonged periods, part of that heat is transferred indoors, increasing the internal temperature and placing greater demands on both the animals and the climate control systems.
A properly insulated building envelope helps to:
- reduce heat gain;
- stabilise indoor temperatures;
- minimise day-to-night temperature fluctuations;
- reduce the operating time of ventilation and cooling systems;
- improve animal welfare;
- provide more comfortable working conditions for staff.
In short, the less heat that enters the building, the less energy is required to maintain suitable indoor conditions.
The building envelope plays a decisive role in the thermal performance of animal farms. Improving roofs and external walls reduces heat transfer from outside, limiting the thermal load that climate control systems must subsequently compensate for.
Spray-Applied Polyurethane as a Solution for Improving the Thermal Performance of Livestock Farms
In this context, Synthesia's spray-applied polyurethane offers a highly effective solution for improving the thermal insulation of livestock farms, both in new-build projects and refurbishment works.
Unlike many conventional insulation systems, spray-applied polyurethane is applied directly onto the surface, creating a continuous insulation layer that eliminates joints and significantly reduces thermal bridges.
This provides important advantages for livestock buildings.
Advantages of Spray-Applied Polyurethane for Livestock Buildings
Continuous Insulation
When spray-applied directly onto the roof or external walls, spray-applied polyurethane creates a continuous, seamless insulation layer that limits both heat gains and heat losses.
Excellent Adaptation to Existing Buildings
Many livestock farms need to improve their thermal performance without carrying out major construction work.
Spray-applied polyurethane can be applied to a wide range of substrates, making the refurbishment of existing livestock buildings easier while reducing installation times.
High Thermal Insulation Performance
High thermal insulation performance can be achieved with relatively thin insulation layers, helping reduce heat transfer into the building.
Fast Application
In livestock facilities where interrupting production represents a significant economic cost, rapid installation is a major advantage.
Long-Term Durability
Spray-applied polyurethane maintains its thermal insulation performance for many years, contributing to the long-term energy efficiency of livestock farms.
Complementary Solutions for Coping with Heatwaves
Thermal insulation is not intended to replace fans, misting systems or climate control equipment. Instead, these technologies perform different but complementary functions.
While climate control systems remove the heat that accumulates indoors, thermal insulation reduces the amount of heat entering through the building envelope.
As a result:
- cooling equipment operates more efficiently;
- energy consumption is reduced;
- indoor temperatures remain more stable;
- animal comfort is improved during periods of extreme heat.
Real Applications in Livestock Farms
The benefits of spray-applied polyurethane have already been demonstrated in real livestock applications. Synthesia has participated in livestock farm insulation projects where spray-applied polyurethane has helped improve the thermal performance of buildings while providing a more stable indoor environment for animals.
Thanks to its thermal insulation performance, spray-applied polyurethane is an effective solution for both new-build and refurbishment projects. When combined with climate control systems, it helps reduce the building's thermal load, optimise energy consumption and improve animal welfare.
