Product Description

facotryliteFactorylite is an effective commercial & industrial roofing insulation which is widely used in buildings without ceilings to create a comfortable environment. Factorylite is manufactured from high quality non-combustible Glasswool with an inert binder, which makes the product lightweight, safe and resilient.

Factorylite is faced on one side with either an ASTM E84 approved reinforced foil, white metalized foil or black metalized foil. Factorylite is ideal for use in systems/buildings where minimal spread of flame, heat contribution and smoke generation is required.

Quality Management System

Insulation Refractory products are manufactured according to ISO 9001:2000.

Features & Benefits

  • Life long energy savings
  • Excellent sound absorption properties
  • Made to length to reduce wastage
  • Lightweight & easy to handle
  • Inert – free of chemical additives or fire retardant chemicals
  • Safe application and use
  • Maintenance free
  • Suitable for high humidity applications
  • Long product life – will not readily age
  • Helps to prevent condensation (excluding black foil)
  • Offers improved light reflection
  • Compression packed for reduced transport costs

Fire Properties

  • Foil faced tested to SANS 10177 Part 5
  • White metalized foil = A1, S1, D0 – tested to DIN EN 13823
    [A = general classification, S = smoke generation, D = droplets]
    Class 1 fire index rating – tested to SABS 0177 Part 3 [only foil faced]
    Complies with ASTM E84 flame spread & fire index requirements]

All non combustible products are acceptable in any application – no deemed to satisfy tests are necessary (SANS 10400).

Thermal Properties

Contributes to indoor comfort and life long savings by reducing heat loss/gain due to its inherent thermal insulation properties.

Acoustic Properties

Offers exceptional acoustic properties & enhances indoor environmental quality by absorption of noise. Subject to application, Insulation Refractory’s insulation may reduce the sound transmission to and from a room or building.


Industrial roof insulation:

  • over purlin installation (new buildings)
  • between purlin installation (existing buildings)
  • Dry wall applications (Gyproc system)


  • Odourless, inert and fully compatible with all standard building materials & components.
  • Will not accelerate corrosion of steel, copper or aluminum.
  • Will not sustain vermin
  • Will not breed or promote fungi, mould or bacteria
  • Non-hygroscopic
  • Rot proof
  • Dust settlement will not hamper the products performance.

Ecological Information

Insulation Refractory’s insulation products are made from glass mineral wool, one of the most environmentally friendly insulants available.


Insulation Refractory’s insulation products are made from silica sand, the earth’s most abundantly occurring mineral and a sustainable, infinite source.


Approximately 50% of the raw material used in the production of Insulation Refractory products is recycled. The recycled material can be post-consumer glass (from housing) or waste glass from flat glass manufacture, which would otherwise go to landfill.


The manufacturing process does not use or contain CFC’s or any other damaging gases. In addition the unique compression packaging ensures better vehicle utilization, reducing the environmental impact of transportation.


Packaged in branded clear polythene bags with label

Tools Needed For Installation

Straining wires
Galvanized hoop irons
Pop rivets
Heavy duty staple gun
10 mm wire staples

Installation Instructions

Caution: Take care when installing in windy conditions.

Install only in dry ventilated buildings after flooring & screeding is completed to prevent alkaline damage to the facing.

  1. Factorylite can be spanned up to 2.15 m without support between purlins.
  2. Square up the roll to the structure and leave 225 mm projecting at the ridge and eaves.
  3. Starting at the ridge turn down the 225 mm projection and, using a wooden batten, clamp this projection with G-clamps or plier grips to the vertical face of the ridge purlin.
  4. Shake out excess quilting and wrinkles by hand from the lower end of the roll.
  5. Grip evenly across the width of the end of the roll and apply even tension along its length to take up the excess slack.Battens placed wither side of the insulation and held with G-clamps provide a suitable means for handling the end of the roll.
  6. Lay strips of 2mm thick galvanized hoop iron approximately 1190 x 38 mm wide over the insulation on top of the ridge and eaves purlins; drill through the hoop, insulation and purlin flanges at +/- 150 mm centres and fit pop rivets. Hoop irons should have no sharp, burred edges capable of damaging the facing.
  7. After fixing the hoop iron, the insulation on the loose 225 mm overlap is carefully pulled off the facing, which is neatly turned back over the top of the hoop iron, allowing about 50 mm slack.
  8. Having fixed the first roll, the first roofing sheet can be fixed in accordance with the manufacturers recommendations.
  9. Fit the second insulation roll in the same manner. Prior to butting up the edge of the second roll to the first, the two adjoining 60 mm facing overlaps are turned up, tensioned and fixed to the second roll, centers using a heavy duty stapler with wire staples with no less than 10 mm legs.
  10. The process is repeated to the opposite end of the roof.

Handling & Storage

Store undercover, and in dry conditions. Do not store directly onto concrete surfaces. Do not apply excessive pressure, for example by standing or sitting on the product, as permanent damage may be caused.


Install 50/75/100 mm thick with a thermal performance of [Rval 1.28/1.92/2.56], non combustible, lightweight Factorylite industrial building insulation in foil, white metalized foil or black metalized foil on one/both sides, over purlins (new buildings), between purlins (existing buildings), after tensioning with hoop irons.
