Acoustic Windows and Doors Sealing

To maintain quality and ensure your Double Glazed Windows and Doors perform consistently well in any weather, it is imperative that all gaps are closed. Depending on whether the installation was performed externally or internally, the best sealant will be selected. Just as there are many different types of grades of windows or hardware, there are many different grades of sealant quality. We only use high performance products to ensure the window and door quality is not compromised. Sealant bead at the final stages of installation ensures the possibility of draughts is eliminated and there is no recess that water can penetrate and cause damage, and leaves the appearance of neatness and attractiveness.

Many people have the impression that all silicone gels on the market are the same, but we have found that their properties and, therefore, suitability varies dramatically. Generally, the descriptions of silicone offer little information as to the correct grade and type for a given application, and because of performance variability, there is no one type of silicone sealant that should be used for everything. Using the incorrect silicone or improper use may cause joint failure, contamination of surfaces because of poor application, excessive movement in the sealed joint. To avoid contamination of surfaces, the installer should ensure that the surfaces are clean, all protective tape is removed and that there is no residue. For deep or wide joints, the installer can fill rhe recess with foam packer rod.

Silicone types and features: Neutral & Acetoxy cure; High & Low Modulus

With regards to modulus - silicon sealants are normally classified for use in either glazing, or for building joints other than glazing. In addition, there are further classes of capacity for movement capability, being the high and low modulus. The lighter the force that needs to be applied to stretch it, the lower the modulus. This also means it will be more elastic and have higher movement accommodation. By contrast, the higher the modulus, the more rigid and the smaller the movement accommodation is expected. For work with upvc window frames, it is advisable to use low modulus silicon, because of requirement of high movement accommodation.Many people have the impression that all silicone gels on the market are the same, but we have found that their properties and, therefore, suitability varies dramatically. Generally, the descriptions of silicone offer little information as to the correct grade and type for a given application, and because of performance variability, there is no one type of silicone sealant that should be used for everything.

For deep or wide joints, the installer can fill rhe recess with foam packer rod.

In relation to cure, the terms 'Acetoxy' and 'Neutral' are derived from the curing system, or more precisely the by-products that are emitted as the silicon is made. The type of silicon used will determine how well it will adhere to the materials it is used on. Acetoxy silicone sealants release acetic acid when they cure. Neutral or Alcoxy Neutral silicone sealants release alcohol as they cure. When silicone peels off without assistance, Acetoxy cure silicon was used on upvc frames. By contrast, if it is not possible to disconnect without a silicone remover solution, then a Neutral cure silicon was used.

Price-wise, the difference between low modulus and high modulus is not significant, but the price difference between Acetoxy cure and Neutral cure is evident, and it is disappointing to see evidence of wrong silicon being used for some jobs by renovators or even independent tradespeople. Acetoxy cure is very common, it is more rigid and quick. The main disadvantage is generally, it has poor adhesive function and leaves something to be desired in how well it bonds to plastics, glass, aluminium and Polycarbonate. Shrinkage can be acceptable if it does not contain added solvent.

Neutral cure has much better adhesive properties for a greater number of materials including upvc, glass, aluminium, lead, stone and masonry, and Polycarbonate, it cures with atmospheric moisture and skins over in about 30 minutes, and leaves a shinier, more attractive finish. The negatives include that it is more expensive, and is slower to cure at one to five days depending on thickness, temperature and humidity conditions.

Low Modulus Neutral Cure Silicone offers high movement accommodation and excellent adhesion to almost all building and glazing materials, without any of the unwanted 'side effects' that Acetoxy could possibly cause. For consistently great results in terms of movement accommodation for upvc, good bonding and lasting durability it is necessary to use Low modulus & Neutral cure silicon for primary frame installation. The least appropriate choice for upvc is High Modulus Acetic cure silicon, because although at first, it can initially adhere, it will surprise you how quickly the adhesion will deteriorate and detach.

Sometimes salespeople will try to sell you a cheap substitute, but only too often it is at the expense of quality. When comparing silicones and their prices, it is useful to check if the movement capabilities listed on the container are appropriate. This is recommended because some sealants can contain additives such as fine chalk powder, which is not an active ingredient, in order to make a cheaper and of course inferior product. The downside of using a silicone which has been filled with chalk is that as well as a higher than desired shrinkage when it has cured, there may also be discolouration, and poor adhesion.

Research shows that the most promising potential for lowering environmental impacts of windows is expected to be through the optimisation of the design and specific construction processes, which means increasing the quality of the windows with respect to their main function of saving heating energy in the use phase e.g. lowering the specific heat loss. Raising the amount of secondary material used, or lowering the amount of material required for the same function, may be another ground for optimization of the constructions.   Greater detail on double glazed environmentally friendly can be found here

Is a sandwich made of one thin layer of plastic Poly Vinyl Butyral between two or more sheets of glass. The PVB sticks with the glass, forms chemical as well as mechanical bonds. When laminated with annealed glass, the layer maintains the geometric integrity of the pane in case of breakage.
Also, it gives acoustic insulation as well as providing protection against damage caused due to UV radiation because it cuts almost 99% of UV radiation present in the sunlight.   Continued on the double glazed laminated glass page

There are significant savings in electricity that will pay for your windows in 6-7 years and will reduce your CO2 emissions by about 100-150kg per year. For an indication of energy efficiency of a window or door, look for the U-value or R-value. U-value measures the overall heat transfer coefficient, or how well the window/door conducts heat and is also the inverse of the R-value. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value. Our windows boast a value of 1.8, which means they perform three times better than an aluminium framed window with a typical value of 5.4-5.6. And since windows can contribute to between 15-40% energy loss in a building, installing the most energy efficient windows available should be the intelligent homeowner's priority.   For more information double glazed draft proof

After the double glazed windows are delivered to your home or the construction site, ideally they should be installed as soon as possible, to minimise the risk of accidental damage.

Low-e glass brings out the best that technology has to offer for improving your views and comfort! A cool, metal oxide coating is applied to clear or tinted glass, so that the appearance and performance are the same regardless of glass thickness. Low-e glass is recommended by many energy efficiency experts as a result of high performance combined with aesthetics. Low-E glass typically cost about 15% more than ordinary glass, but they reduce energy use by as much as 30-50%, by using most of the heat gain in winter but keep the harmful UV rays out during the summer, and when used in insulated glass units - can have even better benefits.
For hot climates, low-E coating should be applied to the outside pane of glass. If the windows are designed to provide heat energy in the winter and keep heat inside the house typical of cold climates, the Low-E coating will maximise benefit by being on the inside pane of glass.   Read more on double glazed low e glass
