Internal and External Condensation time of year again

condensation

In the Spring and Autumn we get thousands of visitors trying to find answers to their problem with internal and external Condensation it is that time of year again.

I have written about condensation elsewhere and the Glass and Glazing Federation (GGF) have free data sheets on (myglazing.com a new consumer website) explaining it in detail but there have been very few remedies for Internal and External Condensation .

This site is privately owned and it has very little income, however we never receive any sponsorship deals, kick backs or payment for advertising, so any article is entirely self generated on its own merits because we think it may help you to find a solution.

Internal and External Condensation, what’s the difference?

Internal condensation, (between the two sheets of glass) generally occurs because the perimeter seal has failed allowing moisture and air to be sucked into the cavity. once inside globules of water form and the unit is considered to have failed.

Undoubtedly the unit will not be working to the same efficiency as a perfect unit, but there is still two sheets of glass compared to one, so some efficiency remains. Traditionally there’s been just one solution, remove and replace the offending unit. That requires the original company doing it for free under their guarantee or finding a new installer who may see the opportunity to charge for a days work!

Well there is now an alternative but be careful there are some worrying comment on blog sites about claims being made concerning some of the systems being employed.

Put simply, the alternative is to drill a small hole into the failed unit, then wash the cavity with a high pressure jet and special formula, so that all the internal surfaces are coated which then prevents the units from remisting. There are a couple of companies now offering these services do try these people “Mist be Gone” or another company “Get the fog out”

Then there is the newer phenomenon of super efficient sealed units, getting condensation forming on the outside surface, over night know as external condensation. This is no different from car windscreens, but we are far less tolerant about it forming on windows!

Again there is very little that can be done, we have heard of some people putting cling film onto the outside and taking it off in the mornings, whilst others are resigned to wiping it dry with a cloth.

We have suggested a company called Ritec and their clearshield in the past, as they have a system that can be applied to glass, so that rain is dispersed immediately, either forming globules which run down the glass or dispersing like oil on water. It can be applied onto windows insitu or ordered with your new windows.

We have yet to have any feedback regarding the success of these products so please don’t take this as recommendation, simply helping point you towards companies that claim to provide solutions on condensation problems.

Companies and reviews listed on this web site are unique

tick boxes

Dear Reader,

The companies and reviews listed on this web site are unique on the web. They are independent and the companies are not forced to pay us anything just to appear (they can appear for free), something which often happens on many comparison web sites. Often these sites simply capture your name, and then sell it onto windows companies as a “lead”.

Companies are free to write their own introduction but the review process is completely unbiased, only users can write reviews, and everyone gets published in some form (unless they are defamatory or litigious), we simply display the results , as voted for by users, there aren’t any “featured companies” or “special promotions”

We’ve even gone an extra step, in that we monitor suspicious behaviour too.

We have caught out companies that tried to add several “reviews” from the same IP address or several reviews against a number of companies (their competitors). Nothing in this world if 100% fool proof, however we do take the review process seriously and monitor our site, regularly.

For that reason, you can be assured that every effort has been taken to monitor the authenticity of these reviews, even having comments from the companies themselves

If you have a question about the our site or the reviews please email info@doubleglazingcompanies.com

Just how old is double glazing ?

window frame

If you have every wondered just how old double glazing is then you may be interested in this article. Today the term Double Glazing is synonymous with cheap, shoddy, imitation windows that have blighted our housing stock. Because of this devastation respected authorities such as Historic Scotland, Historic England and numerous local planning departments consider Double Glazing, to be an inappropriate, modern invention, destined to damage the aesthetics of sensitive buildings.

Well you may be surprised to learn that whilst the excellent properties of glass have been known for centuries, we can now celebrate over 150 years of sealed units. The term double glazing was established when Thomas D Stetson in August 1865 patented the ideal that two sheets of glass separated only with a wooden stick and tar, would significantly increase the warmth of a room and reduce the heat loss by 50%

Double Glazing is principally, two sheets of glass held adjacent to each other but separated by a spacer and sealed around the perimeter to prevent moisture penetrating inside the cavity of air or nowadays gas. Interestingly reading the patent the reasons for the his invention then are much the same as those that exist today, in that

“it has long been known that doubling or trebling the glass has the effect of very greatly retarding the escape of heat from apartments and also of deadening the sound due to movements in the streets”

It seems from reading the patent that he acknowledges others had previously recognised the same benefits that two sheets of glass provided, however they were not joined as one unit (his invention). Furthermore he knew that making a sealed unit “off site” would allow glass to be cleaned more effectively and the unit manufactured with far better consistency than previously seen.

Why then is there so much resistance to harvesting the thermal benefits of multi layered glass units and reducing the noise from the movements in the streets below?

Is double glazing still a modern idea.

Seems the main objection lays with the change of appearance and that double glazing is still considered far to modern an invention, to warrant consideration.

Admittedly two sheets of glass, especially modern float glass, will reflect light differently to a single piece of drawn or blown glass, this will reduce the aesthetic appeal of abuilding; however our world now demands that we conserve far more energy than ever before, that we consume less fossil fuel and decrease carbon emissions.

Perhaps it is time to revisit the way our forefathers sought to reduce heat loss and put the needs of homeowners and energy savings ahead of minor changes in buildings aesthetics.
