If you want to add a solar system to your home, first invest in good insulation, efficient lighting, appliances and windows. That reduces the overall electrical use before you install a solar electric system

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.

New Construction

 

Installation of Double Glazed Windows in new homes or buildings is usually performed by the builder and his team, however, we are prepared to quote and provide an installation service if required. Installation fee is calculated on a per item basis and depends on the size and quantity of the items. The installation quote ordinarily includes glazing, but we can also provide a quote for installation excluding glazing, or a glazing only installation - we are flexible and understand that client circumstances vary.   More info on double glazed new construction

 
     
 

Replacement

 

Installation of replacement double glazed windows and doors or for new constructions includes removal but not disposal of existing windows, and includes glazing, which involves fitting glass into the frame.

Measuring Your Window

 

The most important part of the installation procedure for double glazed windows and doors, comes before you even order your windows. It is critical that you measure your old window opening properly and accurately. Pvc double glazed windows and doors are custom-built and can't be returned if the size ordered was inaccurate. This is why for all replacement windows and doors and some new constructions, our trained technicians will take their own measurements before manufacture. All of our double glazed windows and doors are manufactured to a high accuracy, so ideally you should get the closest fit possible.   Extra information about double glazed measuring your window can be found here

High Performance

 

For windows and doors that do more than just open and close, but actually work for you to reduce your household or office energy bill by utilizing an energy efficient profile system and double glazing. Convenient and comfortable in many ways, they are an essential part of insulating your home or office, for a more sustainable living experience. A standard aluminium sliding window can add 40% heating/ cooling loss in the home. Would you purchase an appliance that can only ever operate at a maximum 60% capacity? But this is essentially what you are doing when your home is poorly insulated! The same high performance extends to acoustic insulation, with a potential reduction of 45dB in our casement, awning, tilt&turn and bifold range. The high-tech weather seal in combination with fusion welding of frames and sashes make the windows completely air and water tight - they have been tested to withstand even cyclone strength winds!   Get all the facts on double glazed high performance

 
     
 

Laminated Glass

 

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

Climate Control

 

The power of the sun is generally underestimated. In one home, we measured 7kW of solar energy per hour on a sunny day in January, which is enough to some of your home appliances including air conditioners and heaters. This means that the same amount of energy is heating your home as you are using on an appliance to cool it! Upto 40% of heat or cold, depending on the season, can be escaping your home through badly insulated windows. Would you buy an appliance if you were told it could only operate at 60% capacity? And yet if your windows and doors have an inadequate u value score, you could be undermining your efforts to cool/ heat your home. Double Glazed Windows and Doors offer full control of your surroundings through a tight weather seal to insulate your home and make it energy efficient.   Greater detail on double glazed climate control can be found here

Toughened Glass

 

Also known as tempered glass, it is a type of safety glass that has increased strength and will usually shatter in small, square pieces when broken. It is used when strength, thermal resistance and safety are important considerations. At home you are likely to find toughened glass in the shower and sliding glass patio doors. For commercial structures, it is used in unframed assemblies such as frameless doors, structurally loaded applications and where there is a danger of human impact. Toughened glass is typically four to six times the strength of annealed glass.   Great suggestions and more on double glazed toughened glass can be found here

 
     
 

Handling and Storage

 

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. However, we understand that this may not be practical if there are other renovation or construction work being completed - in this case, it is best to store the double glazed window/ door frames and glass separately and in an area with limited access, so that the upvc window frames and insulated glass units experience the least movement possible.   Extra information about double glazed handling and storage can be found here

 
     
 

Glass Warranty
