JWS Windows

JWS uPvc casement windows offer you the chance to specify your optimum combination of fixed and opening windows. A wide range of sizes and styles are available. You can specify how many openings each window has and whether these are side or top hung.

Jones Window Systems use RCM reinforcement within its window frames. This is supplied as a thermal improvement to either steel or aluminium sections, RCM is an eco-friendly alternative offering superb benefits where the anchorage of hardware is required in windows, casement window sashes and door outer frame.


The method of fixing RCM is simple and is done in the conventional way that metallic reinforcements are fixed. It can be easily welded and can provide 20% - 30% higher weld strength than using traditional reinforcement materials. RCM boasts excellent screw retention, with a screw pull out value greater than steel.

  



JWS Window Profile

Recent Government legislation has been implemented to improve the standard of products offered to the general public by window fabricators. Windows and doors are no longer elements used to simply fill the gaps in the bricks and mortar. They are expected to fullfill specific requirements. One of these requirements is Energy efficiency. These developments in the double glazing industry now mean double glazed windows can be rated the same way as white good (as fridges are currently).
This simple scheme controlled by the BFRC (British Fenestration Rating Council) allows windows that have been put through a rigorous testing process, to display a rating from A to G (An 'A' rating being the highest certification).

There are two major reasons why you should choose windows that carry an ‘A’ rating when you improve your home;

1. They save you money
2. They are better for the environment

JWS only produce the Ultimate Window Rated "A"

In simple terms, energy rated windows utilise the suns FREE solar power to help heat your home.

  

Excellent insulation qualities ensure that ‘heat loss’ through your windows is kept to a minimum. With energy costs rising every year both of these functions result in your heating bills and energy consumption being dramatically reduced and could reduce your heating bills by a considerable amount every year (based on 20% of your homes heat being lost through single glazed windows)

Heat loss from a House

The Rules about reducing Britains carbon Emmisions are constantly changing and becoming more challenging. Recently the Government changed the limit on CO2 emissions from a reduction of 60% to 80% by the year 2050. Earlier reductions in CO2 emissions have seen a recent change to Part L of the Building Regulations. The thermal efficiency of buildings in Britain will continue to improve with zero carbon emissions targeted for 2016 in new housing and schools, 2018 for public buildings and 2019 for all other non-domestic buildings.

JWS uPvc Windows . . . a better way !

So exactly what are Energy Efficient Windows? They are windows that help to contain and conserve heat within the home keeping out wind and rain, resisting condensation and yet allowing natural “free” energy - the warmth of the sun - to heat the home.

The BFRC Scheme is the UK’s national system for rating the energy efficiency of windows. It is recognised within the Building Regulations as a method to show compliance for replacement window installations.

Energy Efficient Windows are easy to recognise - simply look for the BFRC Label pictured left.
