CoolZone incorporates BASF Micronal phase change material (PCM) into Armstrong’s plain metal ceiling tiles. The phase change material encased in the cassette stores and releases large amounts of energy, reducing cooling costs and maintaining a comfortable temperature in which to work, live, learn and play.

- Available in 600 X 600 modules with Tegular 8/16 or MicroLook 8/16 edge details
A solution for your future energy ambitions, tailored for each building:
- Offices and meeting rooms
- Lightweight buildings
- New and existing buildings
Companies reduce energy costs. Employees enjoy greater comfort. And the environment breathes more easily.
Armstrong’s CoolZone solution improves thermal comfort and contributes to the intelligent energy management and commercial success of a building in a number of ways...
Energy saving: -40% of the HVAC energy cost.
- Delays the onset of air conditioning by 4 – 5 hours with a potential saving of 40% of the HVAC energy cost1
- Achieves full carbon payback in as little as 3 years2
- Saves more energy than is embodied in the phase change material – a 1:10 CO2 efficiency2
- Reduces high-usage peaks for air-conditioning systems
- Smooths out temperature fluctuations, reducing air-conditioning cycling frequency
- Stored heat can be purged in three to four hours1
- CoolZone requires no energy – it is a passive solution

Thermal comfort: 22° stabilised room temperature
- CoolZone panels help to maintain an even temperature, ensuring greater comfort for building occupants
- Temperature variation in the room can be reduced to +/- 10C
- Maintenance free and outlasts a conventional HVAC system
- An ideal approach for renovation - CoolZone cassettes can be moved within rooms and buildings to deal with areas of high heat load
- A long lasting and portable asset – 30 year service life and capable of being moved from building to building as your needs change over time
CoolZone - Lightweight thermal mass ceiling for classroom comfort meeting the new Priority Schools Building Programme Output Specification to reduce the risk of overheating.
The Priority Schools Building Programme (PSBP)
- Applies to more than 200 schools, programme starting in 2014
- New Output Specification considers occupant comfort and replaces BB101
- Benefits thermal mass in classrooms to reduce the risk of overheating
- This new legislate applies to all future schools
Designing to meet the Output Specification
- Design the building to limit the maximum internal temperature
- Ensure mechanical ventilation is not the sole method of summer-time ventilation
- Classrooms to have openable windows and vents
How CoolZone lightweight phase change material (PCM) can help
- CoolZone stores heat energy, keeping the classroom below 28°C between May to September
- When used with natural ventilation, CoolZone helps to manage occupant comfort
- CoolZone is part of a wall-to-wall ceiling solution which helps to hide services and provide acoustical comfort to optimise learning conditions
- Allows for lightweight construction designs over traditional heavyweight concrete structures
How it works
Thermal mass acts as a buffer against temperature fluctuations and is an effective way to maintain a pleasant temperature in summer is to increase the thermal capacity of a structure. This is especially true for lightweight structures, which are more prone to overheating in the summer.
During the day CoolZone cassettes, covering between 30% and 50% of the ceiling, absorb heat keeping the room pleasantly cool and delaying the onset of air conditioning by four or five hours in an average office.
Overnight, the CoolZone cassettes release the stored energy using the cool night ventilation to change back to their solid state.
Heating, Ventilation and Air Condition (HVAC) with CoolZone Cassettes
The performance of CoolZone cassettes is optimised when used in combination with one of the HVAC strategies listed below.
- Natural and passively ventilated buildings
- Mechanically ventilated buildings with or without fan coil units
- Variable air volume and displacement ventilation systems
- Chilled beams and chilled ceilings
Modules & Application
Armstrong CoolZone cassettes are produced from unperforated Armstrong metal ceiling tiles with a 24mm infill incorporating phase change material.
The CoolZone cassettes are suspended in standard Armstrong exposed grid systems and can be installed in conjunction with standard Armstrong ceiling tiles to optimise both the thermal comfort and the acoustic comfort of the room.
- Available in 600 X 600 modules with Tegular and MicroLook edge details
- Other module sizes available on request
- Typically 30-50% of the ceiling area would comprise of the Armstrong CoolZone cassettes with standard tiles and service elements making up the remainder of the installation
Contact Armstrong Ceiling Solutions for information and calculations to help determine the right quantity of CoolZone cassettes for an individual project.
Individual CoolZone cassettes weigh 9Kg, significantly more than standard metal ceiling tiles, and care should be taken during installation.
Due to this weight, special considerations need to be made when considering the grid system.
For new CoolZone installations, Armstrong Prelude 15mm or Prelude 24mm exposed grid systems installation is recommended with main runners at 600mm centres and with hangers at 1000mm along the main runners. The first hangers should be within 450mm of the perimeter trim. This will maintain Class 1 deflection as per EN 13964:2004+A1:2006.
For refurbishment installations, please contact us for specific detailed loading calculations.
As the the CoolZone cassettes are formed from two Armstrong Metal tiles, one with an 8mm return and a one with a 16mm return, the tiles are reversible and can be installed with either the 8mm or the 16mm return visible.
Armstrong CoolZone cassettes are re-locatable and can be easily relocated within a space, supplemented with additional cassettes, or moved to another room in the building as required by the cooling loads. Care must be exercised when moving CoolZone cassettes due to their heavier weight and consideration must be given to the grid support if moving CoolZone cassettes into new areas.
Armstrong CoolZone cassettes should not be cut. Perimeter tiles and tiles required to be cut for service elements should be standard ceiling tiles.
Armstrong CoolZone cassettes require no more maintenance than a standard metal ceiling tile and are washable with a sponge dampened in water containing mild soap or diluted detergent. Abrasive cleaning agents should not be used.
