Supermarket 4’ (1215mm) Night Blinds – Slow Rise/Aluminium backed material Contact

Polar Africa is the southern Africa distributor of supermarket night blinds for one of the UK top brands, Thermasolutions, who have their night blinds installed in Tesco, Waitrose, Spar, Wall Mart, Marks & Spencers, Esso, Carrefour, Wholefoods, Coles, Sainsbury’s, Makro and Costco.



The night blind material used has the capability of reducing energy consumption on upright display fridges by up to 20%, freezer counters and isle cases by up to 30%. Should all the cases in a large supermarket be installed with our night blinds, total monthly electricity bills could be reduced by between 12% and 15% per month – making a return on investment possible between 8 and 12 months post blind installation.

The night blinds are manufactured in the UK (has not been outsourced to another country) and is the only blind in the local market that has been stress-tested by an independent testing authority in the UK to potentially last 10 years – a number of blinds were mechanically opened and closed 3 650 times (equivalent to 10 years of continued usage) with no damage to the blind material or roll-up mechanism.

Find below very useful certifications, endurance test, and energy-saving potential that differentiates our night blinds from the rest in the market:

Our blind survived the equivalent of 10 years of continuous usage by an independent standards body in the UK – I am not aware of any other blind in this country (imported or locally manufactured) having the same accreditation but stand to be corrected if wrong.

Material Safety Data Sheet (MSDS)

Confirmation that the raw material used in the blinds do not comprise any heavy metals, PPB’s or PBDE’s – very important as the product is continually ‘in the face’ of the public when they stretch into a case to retrieve a product to purchase.
