History is an education…

Experience is a great way to learn.

And we have more experience than most.

We have been in the window film game for over 50 years, and there is not much we don’t know about dealing with problems with glass.

Looking back we can see how we have been at the forefront of innovation and technology – as this series of trips down ‘Memory Lane’ will show.

We are going to publish a number of Press Releases featuring old Durable projects from back in the day – working with 3M to solve people’s solar control problems.

So – let’s start with this little gem – a Primary School in Pinner.

The date: 1974


Many educationists are familiar with the problem of solar heat reflected through large window areas causing lack of concentration and a lessening of work pace among school children.

Now Harlyn Primary School in Pinner, Middlesex, has tackled this difficulty with Scotchtint solar control film from 3M United Kingdom Limited.

This transparent film, the first of its kind and by far the market leader, is applied to the inside of windows and reduces solar heat and glare by reflecting the rays of the sun back through the glass. 3M claims it cuts down heat and ultra-violet light from the sun by up to 76% and glare by as much as 83%. It has a life expectancy of at least 10 years.

At Harlyn Primary School, a new temporary classroom built on an open site at the side of the main building catches the sun on its south side for most of the day. Even as early in the year as March, the solar heat seemed to make concentration harder, with the class becoming wither drowsy or even, in some instances, irritable.

Following reports from teachers, Mr T. W. Baker, the headmaster, put the problem to the Hillingdon Borough Architect’s office and Scotchtint film was suggested.

The results were most satisfying. “The film keeps the heat well down on a sunny day, and teachers and children have a much more comfortable atmosphere in which to work,” commented Mr. Baker. “The children are no longer made restless by heat and glare, and are more attentive to their lessons.”

The windows had originally been equipped with roller blinds but they had not provided an effective answer, he said. Now that solar control film had been applied, it was no longer necessary to use the blinds. Lessons did not have to be disturbed by the teacher or class having to adjust the blinds.

Scotchtint solar control films are available from the Industrial Tapes group of 3M United Kingdom Limited.

Children work comfortably in the temporary classroom at Harlyn Primary School in Pinner, because its windows are treated with Scotchtint solar control film from 3M
