Kemwell Passive Fire Protection Accessories

A range of fire stopping products to seal penetrations, openings and joints in fire rated wall and floor constructions

Kemwell has a range of fire stopping products to seal penetrations, openings and joints in fire rated wall and floor constructions.

The extensive range provides options to meet the varied requirements of today’s building and construction projects, providing protection for people and property. The range includes sealants, glues and tapes.

Kemwell’s accessory products are used to stop the spread of fire via the various penetrations and voids that are commonly found in buildings as required in the Approved Document B (Fire Compartmentation) of the Building Regulations.

Products help to reinstate the integrity of the opening in the event of a fire with fire-resistant materials thus stopping the spread of fire and/or smoke by filling the opening.

Effective passive fire protection systems will reduce the potentially dramatic and fatal effect of fire and harmful fumes by stopping the fire from spreading until it is put out or it stops on its own due to lack of oxygen or fuel.

You can specify Kemwell Fire Accessories with confidence.

Kemwell Fire Rated Acrylic Sealant

Main Uses and Features

Main uses
Kemwell FR Acrylic is designed for concrete, masonry and gypsum, sealing cables, pipes and ducts where fire rated partition sections meet.

Kemwell FR Acrylic cures when it is subjected to atmospheric conditions, however, it will retain a degree of elasticity for joint movement.

Features

  • High end formula, certified Worldwide
  • Classified for fire sealing all types of constructions and building service penetrations
  • Very high sound insulation
  • Low emissions – environmentally and user friendly
  • Simple to apply with a smooth surface finish
  • Permanently flexible – will accommodate movement up to 12.5%
  • No priming necessary for application to most materials
  • Suitable for most surfaces, included concrete, masonry, steel, gypsum, glass, plastics and most non-porous surfaces
  • Hardens quickly, tack-free after 1 hour (the fire performance specification of the joint filler has been derived when the joint filler has been let to cure for a month)
  • 18 months storage time (under correct conditions)
  • 30 years working life

Kemwell FR Acrylic has been tested with various types of penetrations through walls, ceilings and floor constructions. Its intumescent property closes any gaps left by burnt away penetrations and will also maintain the acoustic design performance in walls and floors.

Kemwell FR Intumescent Sealant is a 4 hour rated intumescent sealant formulated with fillers that provide noise reduction.

Kemwell HT Glue (High Temperature Non-Combustible Glue)

Main Uses & Product Application

Main Uses
Kemwell HT Glue sticks calcium silicate boards, and building boards onto a wide range of receiving surfaces, including steel, aluminium and galvanised steel

Application of glue

  • The surface to be coated must be clean and dry.
  • Mix well before each use.
  • Apply a film onto 1 or 2 surfaces of the materials to be glued together, depending on the type of surface.
  • Apply glue and apply pressure.
  • The working time depends on the temperature and the relative humidity of the ambient air.
  • A higher temperature and dry air will mean a shorter working time.
  • Drying in ambient air: it is possible to accelerate setting by hot pressing (up to temperatures of between 80 and 90°C). • For interior applications.
  • Dissolves on permanent contact with water.
  • Application tools can be cleaned in water.

Kemwell HT Glue is simple water-based pasting glue that provides an entirely non-combustible film. The film, which is intumescent, enhances the fire resistance of the elements to which it is applied. The products lower than traditional glues setting time allows earlier handling of glued elements. It is classified as non-combustible.

It is ideal for use with Kemwell FPL Fireplace Lining Board system and also for the joints with Kemwell Tecbor and Kemwell Silboard applications.
