Fire Safety

With today’s strict insurance laws, it’s important that your home is both compliant and safe.

The government’s HSE has produced a paper recognising polystyrene as a fire hazard, so if you are considering a new door with a panel, then you need to be aware of the facts. 2004 sees the introduction of the fire rated Styrofoam core, and a fire rated PVCu surface as standard construction on our door panels. We are continuously improving our products to ensure you always have the best.


Enhanced Security

These stunning panels will grace any home.

The cast resin used to produce these bevels is very strong and when applied to the glass, makes the glass far stronger than either toughened or laminated glass.


Composite Doors are available in a range of styles, and glazing options, with an impressive range of colours, (white, black, blue, mahogany, oak, red, green). Door furniture is available in chrome, gold, white and black.. If you would like further information, download the leaflet below

Roto Pincer High Security Sash – double the security.

Loss of treasured possessions and damage to property are the obvious consequences of burglary, but the invasion of your home by a complete stranger can be particularly disturbing for you and your family. The Roto Pincer High Security Sash is a major breakthrough in window locking systems.


Easy to use and secure

Precision engineering provides smooth, effortless operation.

With a simple turn of the handle the unique gearbox activates up to four pairs of high strength, ‘mushroom pincers’, simultaneously driving each pincer into a double-sided security striker from opposite directions.

This double action locking means that any attempt to force one pincer out of its closed position merely forces the opposing pincers deeper into their strikers, strengthening rather than weakening the system’s security.


Energy Efficiency

The British Government’s legally – binding commitment to reduce green house gases is fully supported by Kömmerling.

The company has undertaken an extensive testing programme to ensure all its products not only meet, but exceed the stringent requirements of Part L of the Building Regulations. Under test Kömmerling windows achieved a U – value well below the Government’s target of 2.0 W/m²K.

Kömmerling windows have been tested and proven to perform in all kinds of extreme conditions.

One test took place at 2,300 m above sea level, with windows exposed for 15 years to strong UV – radiation, freezing temperatures and heavy storms. from windows to seals, everything proved to be in the same condition at the end of the test period.

The Kömmerling Connoisseur GOLD specification includes many features and benefits that make it simply unbeatable:

  • Steel re-enforced profiles
  • Multipoint locking and shoot bolts
  • Sealed unit double glazing
  • High impact profiles
  • Home comfort frames
  • Internal beading
  • Colourfast PVC-u
