Ngentile Slate

Ngentile Slate
Slate is particularly suitable as a roofing material as it has an extremely low water absorption index of less than 0.4%. Its low tendency to absorb water also makes it very resistant to frost damage and breakage due to freezing. Slate roof tiles are usually fixed using either nail fixing, or the hook fixing method as is common with Spanish slate. In the UK, nailing is typically done with double nails onto timber battens (England and Wales) or nailed directly onto timber sarking boards (Scotland and Northern Ireland). Nails will traditionally be copper, although modern alloy and stainless steel alternatives are known. Both these methods, if used properly, will provide a long-lasting weathertight roof with a typical lifespan of around 80–100 years.

Fire Stryker

Fire Stryker flame suppressant is a manual, portable aerosol inhibitor with remarkable extinguishing capability. It is non-toxic and environmentally safe. The device is a small, compact, lightweight cylinder: the upper part of the device is a metal tube containing the extinguishing charge. The lower part of the device is composed of plastic and serves as a support handle.


The product works by interrupting a fire’s chain of reaction (the “auto-catalyst” of the fire). The device is composed of stable, solid minerals; it does not contain gas and is not pressurized. The aerosol-like jet is only produced when the charger is stricken with its base. The produced aerosol jet is essentially an inert salt that emits gas already present in the atmosphere.


Fire Stryker is capable of extinguishing fires in different classes:
• Class A: Solid material, ordinary combustibles, such as wood, paper, fabric, plastics etc.
• Class 5B-8B-13B: Flammable liquids, such as gasoline, oil based paints, solvents, alcohol, acetone, etc.
• Class C: Gaseous category: GLP, methane, acetylene, etc.
• Class E: electrical equipment fires subject to voltages up to 1000v at a distance of 1m; Cable galleries, distribution cabinets, electronic devices



The benefits of using Fire Stryker above conventional extinguishers are:
  1. It is light-weight and easy to operate
  2. It puts out all classes of fire
  3. Its needs no servicing
  4. It has a 5 year guarantee
  5. It leaves no residue
  6. It is non-corrosive and non-toxic
  7. It is environmentally friendly.
