This product is class E fire rated and should not be used for projects such as new builds and extensions where Building regulations are applicable.
Wallrock Cosy Liner, Wallrock Thermal Liner and Wallrock Thermal Liner KV600 are all part of the Thermally Efficient Wallpapers range, helping reduce room warm up time and reduce room cool down. As a breathable product, this range also helps with troublesome walls with mould problems.
Spray-applied thermal insulation typically used as exposed ceiling insulation, that has a Class 1, Class A Fire Rating. Mechanically supported insulation system for projects requiring a higher R-Value.
Can I paint thermal wallpaper? The Wallrock Thermal Liner is designed to be painted with its smooth outer facing side. Although we recommend leaving at least 24 hours after applying the thermal wallpaper to the wall to allow the paste to dry before painting over it.
Wallpaper has to meet a class O surface spread of flame in circulation spaces and most do, except heavy and flock wallpapers. Most carpet has to have some degree of fire resistance.
InterNACHI inspectors should be aware that wallpaper can be used to mask structural as well as cosmetic defects, and it can also pose a fire hazard, depending on how and where it's installed.
Fire-rated classifications: Class A or I – Flame spread 0-25. Class B or II – Flame spread 26-75. Class C or III – Flame spread 76-200.
Allow at least 24 hours for drying, longer if conditions are especially humid or cold. Wherever possible we also recommend that the thermal liner is allowed to dry out naturally and therefore the heating is turned off whilst the adhesive dries out.
KV600 is 25% thicker than standard Wallrock Thermal Liner which means less heat escaping through your walls, and rooms that heat up even faster.
Polystyrene is highly flammable and ignites at relatively low temperatures.
Even though it's heavily treated with fire-retardant chemicals prior to installation, it is a recognized fire hazard by the Consumer Product Safety Commission (CPSC). Spray foam insulation will ignite at 700°F.
Cellulose. The most flammable insulation material is cellulose. This commonly used environmentally-friendly insulation is made of up to 80 percent recycled paper fiber.
Different Types and Their Fire Ratings
Fiberglass insulation is commonly non-combustible, as the fibers resist burning. Cellulose insulation, made from recycled newspaper and treated with fire retardants, also has good fire resistance. However, if exposed to fire for extended periods, it can ignite.
You can use Wallrock Fibreliners directly over the Thermal Liner (read below about Finish on Wallrock Thermal Liner). If you'd like to hang traditional wallpaper over the Thermal Liner, please hang Wallrock Fibreliner on top of the Thermal Liner first and then you can apply your wallpaper.
Non-woven lining papers, like Wallrock Fibreliner, are made from synthetic fibres and offer several benefits over traditional paper-based lining papers. They are durable, tear-resistant, and have a uniform texture that creates a smooth and even surface for painting or wallpapering.
Wallrock Thermal Liner KV600 600gsm Features:
R Value 0.1 m²K/W. U Value 10 W/m²K. Most effective energy saving wallpaper. Covers damaged and cracked plaster and textured surfaces.
Furthermore Thermal Liner has excellent capability to cover and reinforce poor plaster and other surfaces such as plasterboard, block-work and wood panelling. Thermal Liner also helps reduce condensation problems and in many cases eliminates them.
Graphite-Based Pads are not as common as silicone based pads. It is important to note, that some- not all, graphite based pads have silicone in them. However, graphite based pads benefits can offset the lack of electrical insulation that is oftentimes present.
Paint the joints first as this will fill in any small gaps and then when you sand down and filler it should not damage the Wallrock KV600 Thermal Lining Paper surface.
Thermal Liner creates a warm blanket for your walls and ceilings which significantly reduces room warm up time, stops heat escaping through walls and ceilings, minimises condensation, mould and damp and reduces your energy bills, too.
A good-quality thermal paste, like KOLD-01, takes no time to start performing well. A mediocre paste, in some cases, might take up to 200 hours as its curing period to settle down.
The two layers of 1" gypsum shaft liner provides the 2 hour rating, and maintaining the 4" air gap is as important as the 2 hour rated wall (National Gypsum's representative says the shaft liner and the " air gap is the "rated assembly".)
How can wallpaper have any fire resistance anyway? When a pure paper is adhered to a non-combustible surface it does not necessarily burn easily because it is not in 'free air'. Similarly some plastic coated wallpapers, such as PVC coverings, do not necessarily combust easily (but give off smoke).
Include lettering not less than 3 inches (76 mm) in height with a minimum 3/8-inch (9.5 mm) stroke in a contrasting color incorporating the suggested wording, “FIRE AND/OR SMOKE BARRIER— PROTECT ALL OPENINGS,” or other wording.
