Insulated Doors

An insulated door comes with increased climate control benefits; it retains heat (or cold) and noise, which add up to healthier looking energy bills. iS doors are manufactured with a choice of three different lath sizes; held together using nylon end locks. 77 and 95mm lath is foam injected; this is a lighter option allowing for a smaller barrel and motor – in turn reducing costs. The 100mm lath option offers a heavier duty door which is constructed using a double skin lath filled with a polystyrene insert. All lath types are tested to wind Class 5, offering full protection against gale force winds (BS EN 12444:2001).

There are four different options for an iS door

The iS1 is chain operated, making it the perfect choice for buildings with no power connection, such as farm buildings and ATEX1 rated areas, such as petrol stations and pharmaceutical factories. Being manually operated it has increased economic benefits and requires little maintenance. iS1 doors require a safety brake to conform with health and safety legislation (BS EN 13241-1).

The flange mounted motor roller shutter is commonly used when there is minimal side room. As opposed to a direct drive motor, a flange mounted motor sits within the door’s width. Available as a single or three phase option to suit usage needs and ATEX1 rated drives are also available. The iS2 uses an in-house manufactured, made-to-measure sprung barrel. iS2 doors require a safety brake to conform with health and safety legislation (BS EN 13241-1).

A direct drive motor roller shutter uses an un-sprung barrel which makes for easier and quicker installation. The motor is fixed to the outside of the plate and therefore requires side room, and must be face fixed. Available as a single or three phase option to suit usage needs and ATEX1 rated drives are also available. Direct drive motors come with an in-built safety brake.

With iS4 doors comes a tube motor. This motor is only suited on doors with minimal usage needs (2-4 times a day), and represents a more economical option. iS4 doors require a safety brake to conform with health and safety legislation (BS EN 13241-1).

1An ATEX rated area is one that is at risk from explosive atmospheres; read more about ATEX rated doors here.
