Heating, Ventilation and Air Conditioning (HVAC) systems are responsible for providing thermal comfort in buildings – and maintaining the optimum temperature. 

HVAC insulation can be used in these systems across large-scale commercial and residential properties, including high-rise offices, apartments, airports, hospitals, warehouse and other industrial facilities, ensuring a comfortable living environment. 

Effective insulation is essential for maintaining the correct operating temperature for the different parts of a system – from piping to central heating and air conditioning insulation. As these properties use a lot of energy to create a comfortable climate, working as efficiently as possible is vital.

Why do we need HVAC insulation?

Insulating HVAC systems improves efficiency, reduces carbon emissions and cuts operating costs. It helps keep indoor temperatures stable with minimum energy consumption – forming a comfortable living and working environment for occupants.  

In addition, heating and cooling systems in large buildings can increase indoor noise levels, so insulating services effectively can also improve the overall acoustic performance - reducing disturbance from unwanted nuisance noise. 

Specifying ROCKWOOL HVAC solutions manufactured from non-combustible stone wool results in reduced fire load in buildings offering additional assurance for fire safety and protection.

HVAC insulation is suitable for use in new buildings and renovations. In the UK it can ensure engineering companies, architects, contractors and installers remain compliant with the relevant building regulations and standards. 

 

Key benefits of ROCKWOOL applications include:

  • Improved energy efficiency 
  • Reduced noise pollution
  • Fire protection

Calculator and savings

Insulating the pipework to the standards set out in BS 5422 2009 reduces heat losses by up to 90%.1

Complying with UK standards (UK BS5422), the optimal insulation thickness is determined by the operating temperature of the HVAC unit, median temperature of the piping or duct, environmental conditions and any additional measurements (such as Legionella prevention or desired energy performance). 

Professional installers understand the impact of humidity and temperature, and can assess new or existing properties to advise on which insulation thickness should be applied.

Use our HVAC Calculator  to determine the most appropriate HVAC solutions to deliver the required thermal, acoustic and fire performance.

Why choose ROCKWOOL solutions?

ROCKWOOL insulation is designed to last the lifetime of a building and maintain the same high standard of performance throughout. 

We offer a wide range of HVAC insulation products to suit different systems – from aluminium laminate faced pipe sections, to slab and roll solutions for rectangular and circular ductwork.

Using the power of stone wool, each one improves the energy efficiency, fire safety and acoustic performance (where relevant) of the heating, cooling, piping or ventilation system.  

Our HVAC range is designed to meet the requirements of the EN14303, and almost all products offer a non-combustibility Reaction to Fire classification of A1 or A2, s1-d0.

 

Benefits of ROCKWOOL solutions include:

  • Energy efficiency
  • Fire resilience
  • Acoustic capabilities
  • Thermal properties
  • Circularity

 

ROCKWOOL HVAC products are durable and are generally suitable for applications operating in the temperature range of 0-250ºC, maintaining their performance over the lifetime of the service.

Case studies

 

The challenge

Aldgate Tower is a brand new, state-of-the-art office development, the first phase of a wider regeneration of the Aldgate area in London. This impressive 317,0000 sq.ft contemporary office block comprises 16 floors of Grade A revolutionary office space designed to achieve environmental efficiency as well as low running costs for operators.

The Aldgate Tower project required ROCKWOOL to meet a range of challenging product performance and service criteria.

 

The solution

Over 15,000 linear metres of RockLap H&V Pipe Sections, 5,000m2 of Ductwrap plus Fire Duct Systems were specified as a non-combustible HVAC insulation solution.

 

The results

Excellent communication and a coordinated approach ensured that all products were readily available. Thanks to the UK manufacturing operations of ROCKWOOL, and one of their distributors, SIG Technical Insulation, MEP Solutions and thermal insulation contractor Denco Thermal Ltd, were never short of product with 100% of all delivery targets being met.

Installation

To ensure proper and correct installation we recommend the use of approved Specialist Thermal Insulation Contractors. Specialist Thermal Insulation Contractors are members of TICA 

We also provide installation guidance for the ROCKWOOL HVAC solutions.

HVAC insulation solutions can be specified for a number of applications such as thermal insulation to save energy, to reduce condensation and to prevent freezing as well as solutions for personnel protection in line with health and safety requirements.  It is therefore important to ensure that products are specified correctly to meet the specific application requirements.

 

Key tips3:

  • Securely seal insulation – Follow the supplied guidelines and use aluminium tape to secure seals and avoid gaps. 
  • Use a registered installer – Experienced and approved Specialist Thermal Insulation Contractors will assess the building requirements and recommend the most suitable HVAC solution to meet requirements as well as ensuring correct installation. 
  • Determine insulation solution required – dependent upon the application requirements, we can support the correct specification by calculating specific criteria and recommending the correct solution to meet your needs.
