Inno-Therm® insulation is made from natural fibres from the recycling of cotton and denim materials. It contains no harmful or toxic chemicals so it can be used safely in an educational environment. Have your students watch this short video showing how recycled cotton and denim garments are processed to manufacture Inno-Therm®.

Encourage your students to investigate concepts of heat transfer through the education resource we have developed called the HOT BOX. It is designed for conducting practical enquiries in thermal and acoustic science.

We provide worksheets, ‘eco’ insulation materials and a HOT BOX template to conduct a scientific enquiry with e.g. Y9 class into what is the best type of thermal or acoustic insulation. The students construct our model house with some can use the house template provided to trace round so that it was spatially correct. External wall designs for the  HOT BOX are provided or students can design their own. The students can compare and record heat loss of Inno-Therm®’, bubble wrap, cotton wool, shredded paper, other eco insulation materials provided; and can use a data logger to record the temperature of the houses to see which lost the least heat. We also are experimenting with a acoustic device to see which insulation absorbs the most sound.

Recovery Insulation being a social enterprise, a donation is made to the Schools and Home Energy Education Project/Solar Active Ltd, to deliver training workshops in domestic energy efficiency measures and renewable energy.

We have developed STEM education resources for KS2 and KS3 students, that also encompasses UK National Curriculum learning objectives in English and ICT and focuses upon ‘energy and money saving action’.

The resources are based on ideas that science is all around and scientific innovations and principals can be found in every day objects and materials throughout the home. It also encompasses ideas about the importance of renewable energy use, sustainable building materials and energy efficiency. Tools such as Energy Calculator are available to support school’s teaching in this area. To request more information about these educational resources, please get in touch.

One of the SOLAR STEM resource have students design and create solar-generated model cars – and are given the opportunity to design and construct their own components. Here here is one wheel made from cardboard.
