Insulated roller shutter doors

Huge openings are often required at the interface to warehouses and factories. Maintaining a constant temperature to provide stable condition for workers and products alike can be a challenge. Yet it wasn’t so long ago that an un-insulated steel door was all the protection that was provided.

Today, factory and warehouse operators are increasingly turning to insulated roller shutter doors. While the initial outlay can be more, this can be quickly recouped through improved performance and more reliable operation over the life time of the door.

Traditionally roller shutter door curtains were made up of pressed steel lathes offering no thermal insulation at all. As a development of the product, the un-insulated lathes were replaced with slim insulated panels, typically 12 to 15mm deep and 100 to 120mm in height. Thermal performance was improved but compared to a sectional door with 40 or 45mm thick panels the insulated roller shutter still struggles to meet building regulation requirements.

Today there are two options to consider for thermal control. Insulated roller shutter doors – for example, the sara LBS range – are available with 40 to 50mm deep insulated panels with high quality seals between panels and around all sides of the door.The latest insulated shutters are also available with high speed operation.

sara LBS insulated roller shutter doors are built around a galvanised steel curtain with hollow section lathes filled with polyurethane infill, providing a high level of insulation that helps facilities to meet energy code requirements and enables operators to reduce energy costs.

Doors are tough as well, with the galvanised steel curtains – combined with injection moulded Nylon-6 end fittings and galvanised steel guides, coil covers and bottom rail – providing protection from vehicle collisions, break-ins and vermin that could nibble a hole through weaker materials. Plastisol and powder-coated finishes are available.

The doors can be supplied with manual push up, hand chain or electric motor operation and are suitable for use in industrial environments or as loading doors for warehouse loading operations.
