One of the largest drains on businesses’ resources can be its energy bills.  By adding the highly efficient protective layer to your buildings given by premium quality commercial glazing, energy bills can be reduced whilst retaining warmth and comfortable surroundings for your employees or guests.

What is an A rated window?

Energy ratings on window glass are rated from G through to A, with A being the highest level of energy efficiency.  Many double glazed windows fitted over the last decade only have an E rating or lower.  We will be delighted to assist your business by discussing the most cost-effective way of bringing your windows up to an A rating. This not only reduces costs on energy consumption but it also enables your business to boast a more effective environmental policy.

Planitherm works by using advanced coatings which make the most of natural light and energy from the sun. Their glass has been shown in energy savings calculations provided by the Glass & Glazing Federation to save up to 28% off energy bills on domestic properties and significant cost savings can be brought into the work place.

24-7 Glass and Glazing are delighted to install A rated windows within the window frames you wiah to have fitted in your business premises.

planithermOne of the features that sets Planitherm glass apart from more conventional glazing is the way in which its advanced coating reflects warmth back into a room rather than allowing it to escape back out through the glass. This in turn means you need to use less energy in your office or business premises to meet the desired temperature.

An additional bonus of Planitherm glass is that it has been developed to almost completely eradicate problems with condensation which commonly arise in more conventional window glass.

triple glazingThe only thing more energy efficient than having the right glass in double glazing is having the right glass in triple glazing. With the cavity filled with gas, Planitherm glass fitted in triple glazing achieves even greater protection for your building against heat and energy loss.

A greater amount of solar energy is captured in the first place and this is then combined with glazing to have better insulating properties. As less heat is allowed to escape, combined with the greater amount of heat extracted from the natural surroundings (sun), the savings and energy efficiency achieved is even greater than those attributed the A grade energy rating.

Cold areas of your interior are often eliminated through the added efficiencies brought by triple glazing. There is also an added benefit of reduced noise from busy roads and traffic, road works and other noise pollution that can distract your personnel or disturb the comfort of visiting clients. Triple glazing also makes for a more secure exterior to your building – thieves and vandals may have to work out another way to get in as three panes of glass are inevitably harder to get through.
Pilkington K glass works in a similar way as it also allows free heat to get through into your building whilst preventing heat from escaping – earning it the label ‘Thermal glass’. This is achieved through the use of specially developed coatings.

On K glass the coating is located on the inner panes surface, on the side pointing in toward the cavity of the insulating glass unit. The coating is deliberately designed so as not to be a good radiator of heat. That way the warmth is not transferred out to the colder outside pane and into the cooler outside air. Instead it is reflected back into your home or business premises interior. So put simply, it allows warmth in easily, but doesn’t let it escape so readily.

The energy efficient glass allows up to 78 % of the natural energy to get into your buildings interior. This is comprised of 66% which passes directly into your premises and a further 12% which is trapped in the window and eventually works its way through to the interior of your office or business premises.

Property developers, housing associations and councils which are developing houses and properties and are mindful of the Part L 2010 regulations on new and existing dwellings and changes expected in 2013 and 2016 may well want to consider Pilkington K Glass S. It is a unique soft coated glass which enables households to reduce energy consumption and save on heating costs. Drafts can be reduced and the need for artificial light is reduced through the benefit of allowing extra natural light through.

Therefore when considering the reduction in costs on properties and business premises it is worth considering light as well as heat.

If safety glass is required in public places, schools, nurseries etc. then a toughened version of this product can also be provided.

We are able to supply and fit double glazed sealed units which are filled with an inert gas called argon.

How does argon gas help to keep my home insulated?

The ‘gap’ between the glass in a double glazed unit has to contain something – it is filled in an environment which naturally contains air and so one option is just to have a unit containing regular air. However, despite air providing moderate insulation there are some inert noble gases which do the job better.

One such gas is Argon. As well as being non-flammable, non-reactive and colourless, it also has no odour. Perhaps most importantly it provides the best insulation of the inert gases often used in sealed window units. The convection inside the space between the glass is slowed down. Some brands such as Pilkington K-Glass combine argon gas with a softcoat glass. We can install hardwood, aluminium or UPVC units with the added benefits that argon gas bring.

All sealed unit brands we install which make use of argon gas have passed BS EN1279 part 3 which is a test of the gas concentration within the sealed units and a measure of how much gas leaks out of the units. It needs to remain above 80% concentration in order for the insulation to remain effective. The standards set within EN1279 part 3 ensure that only units which leak less than 1% per year are deemed fit to pass.
