Dangers of Conservatory Insulation and Cladovers
Older conservatories tend to leak or they are too hot or too cold to use as a functioning room, so it’s no wonder that most homeowners start looking at different ways to turn a tired old conservatory into a useable space again, a room that can be enjoyed by the whole family the whole year-round. If this sounds familiar to you, then you have probably been doing research online and may have come across advertisements from numerous companies offering conservatory insulation.
Conservatory insulation is being advertised as a cheap method of making a conservatory thermally efficient. Conservatory insulation and cladovers are not regulated, they are dangerous and will usually end up causing more issues further down the line.
As specialist conservatory installers in Cornwall, we have witnessed first hand the dangers of conservatory insulation and cladovers. Best Glaze LTD has created this article to raise awareness of the dangers of conservatory insulation and cladovers, and to make homeowners aware of the false economy involved.
During this article, we will highlight the dangers of conservatory insulation along with the common problems that occur and other options that are available that will provide you with a new, thermally efficient room that is safe, bright, and useable the whole year-round.
Conservatory Insulations – The Dangers
The main danger of installing conservatory insulation onto your old conservatory structure is, of course, overloading the lightweight frame which in turn could cause it to collapse putting your and your family’s lives in danger. There are other risks of installing conservatory insulation which we will look at in more detail.
1. Fixing into glazing bars whilst insulating a conservatory roof
Most homeowners will be unaware of the fact that glazing bars serve more than one purpose, besides holding the polycarbonate or glass roof panels in place. However, glazing bars also provide other important functions within the conservatory roof structure.
Glazing Bar Functions:
Provide Support and strength to the conservatory roof
A ventilation source preventing condensation
A guttering system for water drainage.
During the process of installing conservatory insulation and cladovers, the glazing bars integrity is compromised when they are screwed into to attach the conservatory insulation. Besides affecting the primary function of the glazing bar, the ventilation and drainage are also affected.
A conservatory roof is designed to be a lightweight structure that serves many purposes. The design process is very technical and a lot of factors are taken into consideration, weight, strength, environmental load, waterproofing and ventilation.
Glazing bars are actually technical components composed of numerous elements to ensure that a conservatory roof can provide adequate support for the intended roof panels, gaskets, baffles and other components to provide a watertight seal. Conservatory insulation companies compromise every one of these integral features when fixing into glazing bars whilst insulating a conservatory roof.
2. Overloading glazing bars during a conservatory insulation project
Companies installing conservatory insulation will attach lengths of timber to the glazing bars which run the full length, adding a considerable amount of extra weight to the conservatory roof. Adding this extra weight will exceed the load limits which were factored in during the design process of your conservatory roof.
Roofing material, glass or polycarbonate, size, and shape of the roof even geographical location are all factored in during a conservatory roof design. The location of a conservatory roof is important, the effect of the weather such as wind, rain and snow all need to be calculated and factored during the design process as they all add strain to the structure.
Designing a conservatory roof is a technical process when you consider how the conservatory roof is designed and all the calculations that are performed in order to work out the strength of glazing bars required for each and every individual roof to ensure structural integrity. Companies installing conservatory insulation exceed these calculations when they start attaching the extra weight of roofing batons to all of the glazing bars.
Overloading the conservatory roof structure with the conservatory insulation timber poses a risk of the conservatory roof collapsing, older conservatories are particularly at risk of collapse. A lot of homeowners may know someone that has had a conservatory roof insulated and not reported any problems, but a roof could collapse at any time which puts you and your family at risk of being injured or worse.
3. Conservatory insulations total thermal block
Companies installing conservatory insulation and cladovers will often promote a total thermal barrier as a selling point for conservatory insulation. Homeowners looking to create a warm useable conservatory all year round may also believe this is a good thing, but it is not.
Once timbers are attached to the glazing bars the company installing conservatory insulation attach a thermal quilt and then clad over it with PCV cladding. The installation of these materials creates a total thermal barrier, which conservatory insulation companies claim is good. Once a cladover has been installed there is no way of regulating heat building up in the conservatory. During summer conservatories naturally build up heat and in the winter conservatories are usually heated inside which must be ventilated in an adequate manner to prevent numerous issues from occurring.
Best Glaze supply and install Ultraframe conservatory roofs, we know just how much work goes on behind the scenes when designing a replacement conservatory roof that is going to stand up to the elements, and stand the test of time. We recommend Ultraroof conservatory roofs to all of our customers because we firmly believe that they are the best on the market.
Using trickle ventilation which flows through the ridge and twin chambered top cappings purges build-ups of unwanted heat in a controlled way. When conservatory insulation is cladover existing conservatory roofs heat can enter the room but it can’t leave because it is not adequately ventilated. The roof space will build up heat which subsequently heats the conservatory until it becomes unbearably hot and uncomfortable, once again making the room unusable. Being unusable because of the heat really is the best-case scenario following a conservatory insulation installation.
The worst thing that could possibly happen is heat build-up could dangerously compromise the structural integrity of the conservatory roof and even the whole conservatory structure. This happens because the thermal quilt that the conservatory insulations company installed traps heat around the conservatory glazing bars which are made of PVC which begins to twist and warp if it becomes overly hot. Conservatory insulation installed on a conservatory could affect the integrity of the glazing bars that could result in the bars not holding the glazing material as it should do and large sheets of polycarbonate or glass could potentially slip causing leaks or worse, fall from the roof.
4. Conservatory insulation installation doom & gloom
The main selling point of any conservatory whether it be a brand new installation or an inherited room that comes with a new home is that it is a light and airy space. A conservatory is a peaceful room to wind down and relax in with a good book and a glass of gin.
Conservatory insulation creates a solid barrier between the roof that once flooded your room with natural light and the area below it becomes a dark and gloomy area. Not only is the conservatory turned into a dark area but the adjoining rooms are also affected, all of the natural light that once flooded into the adjoining rooms will also be blocked out by the cladover.
5. Fire safety in conservatory insulations Non Existent
The additional materials added to your existing conservatory roof when having a conservatory insulation installation will without doubt add to the risk of fire spread should a fire start. As conservatory insulation companies can not fire test the products on conservatory roofs they can not guarantee how the extra materials used in a conservatory insulation installation will perform should a fire break out and spread to the conservatory.
The replacement conservatory roofs we supply and install are the only fully fire tested roofs on the market, this is important to us being a family run business, you can have peace of mind knowing that your new roof is safe and secure for both your home and your family.
6. Conservatory insulations voids guarantees
Companies installing conservatory insulation will make your conservatory guarantee null and void. Fixing extra materials to your conservatory roof by drilling and screwing into your conservatory roof goes against the warranty as it makes the structure unsafe. The fact that drilling into or fixing onto the conservatory roof structure will void any guarantee or warranty should give you an indication that this kind of conservatory insulation is a bad idea…
