Clearly Focused on Ecoease!

Richard Armes had two very specific objectives in mind when he decided to install secondary glazing at his cottage in rural Derbyshire.

“I wanted to keep drafts out and bills down!” exclaimed Richard who opted to insulate four windows in his home using Ecoease’s magnetically attached secondary glazing.

“I visited the Harpur Crewe estate near to me which has started installing Ecoease glazing panels and was taken with its simplicity, cost and effectiveness. It can be installed or removed very easily.

Richard went on: “As well as being over the moon with the product I was immensely impressed with the customer service. The staff at Ecoease were very helpful and even advised me that I’d over ordered on the magnetic tape after getting my measurements awry. A lot of companies wouldn’t do that.

“In addition I was sent additional tape free of charge after accidentally cutting it to the wrong length during installation.

“I’m looking forward to feeling the benefits once the winter starts to bite and temperatures drop and, whilst not an intention, I’ve noticed a reduction in noise pollution.

“All in all, a great product and the kind of service you simply don’t come across these days,” concluded Richard.


Age really is no barrier when it comes to installing secondary glazing! Just ask 85-year-old Jean Clarke from Trowbridge in Wiltshire who is in the process of insulating her period property against the elements, noise pollution and condensation.

After reading in the Sunday Times about Ecoease secondary glazing, a simple magnetically attached clear panel that fixes to the inside of window frames, Jean decided to test it out.

Jean commented: “Ecoease seemed like a very cost effective, easy to install system so I checked out the website and rang up and placed an order for my single glazed kitchen window. It was reassuring to talk to a helpful human being at Ecoease!

“It’s a small fraction of the cost of double glazing but could it deliver on its promises? I cleaned the inside of the window frame as instructed and then installed the glazing panel in around half an hour on the same day it arrived.

“In total I’ve now ordered four measured to fit panels for windows in my house and I’ll be completing the job over time. The panels were well packed and delivered by courier on a specified date at no extra cost.

“Noise pollution was an issue for me being close to a road and it’s now reduced considerably. I’ve also seen condensation disappear but I’m now saving energy, saving money and my home is noticeably warmer and more secure.

“I’m very pleased with it and would recommend it to anyone!” added Jean whose positive sentiments are reflected by many of Ecoease’s customers.


It pays to be prepared for challenges such as the impending EPC when you’re landlord of 73 period properties, many listed, dotted around an idyllic village in southern Derbyshire!


Indeed, it was probably here that the phrase ‘chocolate box cottage’ was first coined. Well possibly!


The Harpur Crewe family has run the Estate in Ticknall since the 1500s. The Johnson family from Vermont, USA are the last surviving heirs of the Harpur Crewe’s and inherited the Estate in 1999 and shortly after formed The Harpur Crewe LLC.   The Harpur Crewe LLC is currently installing Ecoease’s secondary glazing in a number of their listed properties with its magnetic tape attachment adhering to local building conservation without making an aesthetic impact.


The impact is all practical, and green, in terms of less noise, negligible condensation, lower energy bills and warmer dwellings.


The magnetic attachment is deemed ‘temporary’ within the EPC recommendations and thus not considered by assessors, however it seems, local building conservation regulations for Listed and period properties override that meaning that ‘temporary’ secondary glazing counts towards EPC.


James Alcock, co-founder of, a website that acts as a shop window and counsel for advice on domestic green technologies including Ecoease, explained “In terms of EPC ratings, the RDSAP manual sets out the EPC methodology guidelines and it says the following.


“This is a calculation of the proportion of total window area which is double or triple glazed. This should include any windows which have permanent secondary glazing fitted, temporary secondary glazing, such as removable secondary glazing or cling film, should be discounted from this calculation.”


“The new rules will force landlords to upgrade the energy efficiency of hundreds of thousands of homes currently rated F and G to a minimum of E by

1 April 2018 – or face being unable to let them until they improve the rating,” added James.


Secondary glazing is a tried and tested solution for properties, many period or Listed, looking to insulate against rising energy bills, especially pertinent given that anywhere between 15 and 25% of heat is lost through windows in single glazed dwellings.


“That could equate to around a 25% cut in quarterly, like-for-like, energy bills. It frequently does,” explained John Feely, a founding director of Ecoease, “In fact many secondary glazing customers report higher reductions.


“We are developing a hinged version that adheres to EPC recommendations and we’re already seeing interest from landlords particularly within urban environments.


“When you’re looking for proven environmental performance and an almost immediate and very measurable return on investment, there’s few better ‘insulations’ against the elements than secondary glazing,” he added.


Costing from around 15% of a typical double glazing installation, secondary glazing panels are generally manufactured from clear plastics such as acrylic, polycarbonate or PET, known as polyester and used in aircraft windows and pop bottles.


In terms of independent fire tests PET comes out top. Currently only supplied by Ecoease, PET crystalises when burnt to act as a virtual fire retardant whilst other plastics act like firelighters and expel toxic fumes.


Amy Biddell, Rural Practice Surveyor with Leicestershire-based chartered surveyors Mather Jamie, operates on behalf of the Harpur Crewe LLC and she outlined their approach.


“The Estate properties are a combination of terraced, semi-detached and detached cottages and barn conversions. Many of the cottages on the Estate are believed to have been built in the 1800s.


“We currently have around 95% occupancy as we are in the process of refurbishing several cottages which have recently been vacated.


“Due to the number of residential properties on the Estate we have decided to start the programme of energy improvements ahead of the 2018 EPC changes.

The Harpur Crewe LLC’s aim is to also provide a better, more thermally efficient standard of accommodation to new and existing tenants in the hope of reducing tenants energy bills.


“Installing secondary glazing is an easy way to improve the thermal efficiency of a property without causing much upheaval for residing tenants.

Ecoease is not only easier to install than glass secondary glazing, it is also significantly cheaper and we have also been advised by our EPC assessor that it is more thermally efficient than glass.


“A full time Clerk of Works, employed on the Estate, fits the Ecoease glazing within the Estate cottages and can usually install within an entire property in one to two days.


“As well as installing secondary glazing the LLC is also incorporating loft insulation, upgrading heating systems, boilers and low energy lighting.


“The Harpur Crewe LLC strives to provide a good standard of properties for its tenants and is always looking for new ways and products like Ecoease to assist in achieving this.  The Estate owners view the new EPC regulations as a good way to improve the cottages for the benefit of their tenants to a bench mark standard.


“The Ecoease secondary glazing has had a positive impact on the energy performance of the Estate Cottages and in many cases, along with loft insulation and low energy light, has enabled us to move many properties EPC ratings into band E and above,” concluded Amy.


Safety and Secondary Glazing



Reducing energy bills, condensation and noise pollution are the main considerations for the growing number of UK households opting to install secondary glazing panels however there are other safety and environmental issues to consider for customers.


The majority of secondary glazing panels sold in the UK are manufactured from acrylic ( more commonly known as Perspex) with Ecoease being the only supplier of PET (Polyester) panels.

Whilst there is no obvious difference in terms of clarity, there are significant differences in terms of how the three plastics compare in fire tests and in terms of recyclability.


Ecoease Director John Feely explained: “Independent fire tests conducted on acrylic, polycarbonate and PET plastic panels reveal some big causes for concern. Acrylic acts like a fire lighter and melts in seconds giving off poisonous Hydrogen Cyanide and Carbon Monoxide.  Polycarbonate , which is used occasionally for glazing, has less toxicity but drips flames when burnt, thus contributing to the fire.


“When it comes to PET, however, when in a fire situation, the material

crystallises   and turns white. This means it can withstand temperatures of

up to 250 degrees C which explains why crystallised PET is used in oven dishes for ready meals and why it has the best fire rating of any available clear plastic.


“In an ideal world we would like to see PET used as standard for all secondary glazing applications. It makes total sense from a safety perspective,” added John.


In addition PET is classed as the most recyclable plastic available with a rating of one on the scale of 1 to 7 used for the recycling performance of plastics. Acrylic and polycarbonate, by stark contrast, are the most difficult plastics to recycle with a rating of 7.


John concluded: “Not only is Ecoease secondary glazing one of the most cost effective ways of insulating homes but it also delivers peace of mind in terms of safety in the event of a fire and is the best plastic glazing

solution currently available for the planet.”


28% Saving on Energy Bill!

There was a very pleasant surprise for Ian Heath of Egham, Surrey when he opened his most recent gas bill at the start of 2015!


His 2013 gas bill had come to £1,122 whereas the 2014 total amounted to just

£809 (when both were calculated at the 2014 gas tariff- which had gone up!).


“That’s a saving of £313; I have paid 28% less than last year,” said Ian, who finished fitting Ecoease secondary glazing panels throughout his home last February.


“It’s a clear sign that the panels are doing their job and performing as good as, if not better than, double glazing at a fraction of the cost.”


“The Ecoease measured-to-fit panels can go up in minutes. It’s safe and easy and they can be taken down in seconds.”


“Compare that with the disruption caused by installing double glazing, which would have cost me over six times more!” added Ian who has fitted the panels to windows in each of the 14 rooms in his house.


Measured to fit Ecoease secondary glazing panels are manufactured from tough, fire-retardant PET (polyester), the same material used for airline windows and soft drinks bottles. Ecoease is the only UK secondary glazing supplier to use PET.


With windows and glazed doors accounting for up to 20% of total heat loss for a typical dwelling, secondary or third glazing provides a highly cost effective insulation against chills as well as delivering dramatic reductions in energy consumption, noise pollution and all but eliminating condensation.


Ian now plans further savings by buying panels for the French windows that connect his house to an unheated conservatory and panels for a few windows around his unheated porch, thus completing the house’s secondary glazing.


“Who knows what surprises my 2015 bill might bring but I only see it heading in one direction!” added Ian.
