Market - Frequently Asked Questions
No. The brand relates to sectors and regions of the UK & Irish markets where DOMESTIC Window Energy Ratings (WERs) are applicable. Hence, non-dwellings (commercial buildings) are excluded on this basis but new dwellings and particularly home improvements are highly relevant.[ top ]
There has been widespread news interest in global warming and the damage to our environment as well as in the escalating costs of energy for the home in terms of the prices of electricity, gas and oil. Therefore, it is expected that homeowners will more than ever be interested in saving money on fuel bills and doing their bit for the environment. By installing replacement windows incorporating Pilkington energiKare™ they will be reassured that they are doing both.[ top ]
Part L changes in 2010 are expected to raise the minimum performance level of replacement windows to Window Energy Rating band C.[ top ]
C4. What might the different selling messages be in Scotland bearing in mind the slightly different regulations?
In principle the Scottish market is no different both in terms of replacement and newbuild markets. Performance of Pilkington energiKare™ is in excess of that required by any UK or Ireland regulations hence the proposition is value added rather than mass market.[ top ]
As Pilkington don’t sell windows we can’t advise on the price to the householder. However, given that the cost of the IGU is a small proportion of overall installed window cost then we would expect that even A-rated windows should incur no more than a 10% premium over standard Part L compliant windows. Overall we would recommend that Energy Efficient Windows are an opportunity for Window Installers to improve margins.[ top ]
We would recommend that they are offered at a premium as noted in C5.[ top ]
C7. Just how much will the average home energy bill be reduced through the installation of Pilkington energikare™?
Windows containing Pilkington energiKare™ can reduce home heating bills by over 20% when compared with existing glazing.[ top ]
C8. What is the average saving to householder between A, B & C rated windows in terms of energy and cost savings?
A, B and C rated windows are all much more energy efficient than standard windows. That said, there are differences in performance of energy efficient windows with A B and C ratings;
- Changing existing single-glazed, timber windows to Band C windows in a semi detached, gas fuelled house would be expected to save £4350 in heating costs and 11 tonnes CO2 over the life of the windows.
- If the new windows are instead B-rated then the savings increase to £4650 and 11.5 tonnes CO2 .
- And, if the new windows are instead A-rated then the savings increase to nearly £5000 and over 12 tonnes CO2 .
The above shows that achievement of the level C displays significant savings over existing windows with higher ratings of B and A delivering further smaller incremental savings above C.[ top ]
20 years consistent with the approach taken by the GGF.[ top ]
4 mm Pilkington Optiwhite™ is available in the following sizes;
6000 x 3210 Jumbo
3210 x 2250 LES
3210 x 2100
SSS sizes are not stocked by Pilkington but may be sourced from local partner Merchants. Additional sizes may be added in future.
C11. Why is Pilkington Optiwhite™ more expensive than Pilkington Optifloat™ standard clear float glass?
Due to higher priced raw materials, additional costs incurred in the manufacturing process at substantially lower volumes than regular float and the need to import it from our sister company in Germany. Being able to manufacture in the UK at reasonable volumes will enable us to reduce our cost to supply.[ top ]
As the market develops in the future we will review the capability requirements of all of our own sites. Currently our proposition for customer’s C-rated windows is to use Pilkington energiKare™ with aluminium spacer bar and Argon from most branches. In the future there will be increasing requirements for adding warmedge spacer bar so we will continue to review and decide on the most appropriate technology to implement within our branch network.[ top ]
C13. How difficult is it to be approved for Argon filling of IGUs and how many companies have achieved so far?
No central database exists for EN1279-3 passes and failures. It is clear that IGUs need to be manufactured to a high standard to retain sufficient gas to maintain performance. The pass rate for dual sealed IGUs seems to be higher than for single seal systems and this is reinforced from wider experience within mainland Europe where adoption of the standard is more widespread and the pass rate is now greater than 80%. Many companies in the UK & Ireland are passing the standard and using this to their advantage by becoming Pilkington energiKare™ Partners.[ top ]
We expect that triple glazing requirements will increase over the next few years as the Government tightens the legislation concerning the conservation of fuel and power in new homes. The timetable set out for achieving zero carbon homes indicated that this would be by 2016 so housebuilders will be looking for the means to achieve this. Triple glazing will enable them to keep the large glazed areas that homeowners like as well as benefiting from increased passive solar gain and thermal insulation.[ top ]
In these difficult times we want to add value for ourselves and our customers by differentiating our offering and further uplift the market position of Pilkington energiKare™ energy efficient glazing. In this way we can also maintain the value in Pilkington K Glass™, best exploit our UK manufacturing capability and ease the operational difficulties of dual stocking of Pilkington Optifloat™ and Pilkington Optiwhite™. It’s a significant opportunity for window companies to help homeowners save money on energy bills and help the environment.[ top ]
C16. Won’t Pilkington just increase prices in future once customers are committed to Pilkington energiKare™ as standard?
Pilkington energiKare™ will become our default IGU offering priced as per Pilkington Insulight™ units previously. We have been able to offer competitive pricing supported by UK manufacturing base in 2009. In future we will price to reflect market conditions but we are looking to reward and maintain loyalty with this initiative not penalise customers.[ top ]
When you exchange Pilkington Optifloat™ for Pilkington Optiwhite™ it increases IGU light transmission by 2% and IGU solar gain by 6%. So Pilkington energiKare™ is entirely appropriate in domestic windows, doors / patio doors, roof-lights, conservatory verticals and replacement units, and beneficial in most areas except those sensitive to overheating. Where overheating is a possibility then tinted or solar control products should be used in any case, not Pilkington Optifloat™. Such products include; Pilkington Optifloat™ Tint, Pilkington Activ™ Blue or Neutral, Pilkington Eclipse Advantage™, Pilkington Suncool™ and Pilkington Activ Suncool™.

Firstly, please discuss your concerns with your Pilkington Representative so that we may understand the issues for you. As noted above, Pilkington energiKare™ looks better and performs better than our existing IGUs as well as having the benefit of being back by branding, consumer marketing and a wide range of sales support materials to help you sell. Hopefully we will be able to address your concerns to enable you to benefit from this energy efficient glazing in your windows.[ top ]
C19. What if I already pay a premium for Pilkington energiKare™ over standard Pilkington K Glass™ IGUs, how will Pilkington’s standardisation affect me?
In the current market climate, where premiums do exist they are generally for Pilkington energiKare™ Plus rather than for Pilkington energiKare™ Classic for which this offer applies. Therefore;
- Current Pilkington K Glass™ /argon/Pilkington Optifloat™ prices will be used for Pilkington energiKare™ so the default is NO PREMIUM for Pilkington energiKare™ Classic.
- Premiums should remain for the addition of warm edge (Pilkington energiKare™ Plus) or where Pilkington energiKare™ was supplied as part of a price negotiation at the time of a general price increase.
C20. Which products are included in the Pilkington energiKare™ standardisation and which are excluded?
IGUs for domestic applications are included ie. those made from 4 / 6 mm annealed or toughened or 6.4 / 6.8 mm laminated.[ top ]
C21. What will be done about the supply and pricing of Pilkington Optiwhite™ stock and single toughened glass now that Pilkington are supplying Pilkington energiKare™ as standard to IGU customers?
We will address the pricing of Pilkington Optiwhite™ to our independent and Merchant customers to enable them and their customers to benefit from the reduced cost of making the product in the UK and hence get involved with the Pilkington energiKare™ scheme.[ top ]
