Glass is comprises of mainly silica that is found from sand. Glass is used in various applications as doors, windows, conservatories, bottle, and vision glass.

These glasses when used in windows (double glazing window) can act as energy exchanger and can reduce the efficiency. To increase the efficiency of the room, the energy exchange should be measured either from window frames or glass.

Pilkington K glass has a special coating on the inner glass surfaces facing the air gap which reduce the energy emission to the outer glass.

A thin coating helps to reflect back the energy and maintains the internal temperature towards the colder outer atmosphere. This coating helps to reflect back the energy and also allows heat from sunlight to enter the house so keeping the residence warm. Thin coating on the inner glass sheet makes it at room temperature and provides larger usable space.

Pilkington K glass helps to maintain the internal room temperature with or without heating making it greener by energy saving to home so with Pilkington K glass you can achieve higher efficiency.

In colder atmosphere the window region is the coldest part of the house but with Pilkington K glass it is not the case. It can also be used in conservatories as it maintains the heat from sunlight and make the inner atmosphere pleasant.

Pilkington K glass can also be laminated or toughened to increase its strength and durability. Due to its energy efficiency it becomes the first choice for architects and also raises the energy ratings and saves on energy bills.

When PVC and aluminium replacement windows were first introduced to the market, there were those with no appetite for conservation and preservation of our heritage, whose main priority was to cost effectively replace tiresome and decaying timber windows. Wooed by the sales messages that promised maintenance-free products for the ever after, these home owners were happy to accept the limited designs available, believing them secure and trouble free.

Over time, these windows did not prove to deliver on their promises. They were seen to be prone to erosion and discoloration. Many designs became fire traps in what were often the lower income households where safety was not always top of the agenda. Subsequently, fires resulting from faulty electrics, careless smoking and cheap furniture, in houses where exitless windows had been installed, became a lethal combination.

Sash windows are a particularly emotive subject in the world of windows and in complete contrast to those mentioned above, there are those who would never replace their original windows. Very often sashes feature in Victorian and other period homes which carry with them a certain snobbery. A three bedroom Victorian terraced house will be priced to reflect its history and tradition despite its higher maintenance costs and often more time consuming life style. And, naturally, the sash windows have to be timber to continue the look and feel of period charm, regardless of the normally hideous wasted energy lost through them every year.

In days gone by, timber sash windows were lovingly restored and serviced by owners who in those days had the time and inclination, and the skill, for home maintenance. In addition, there were expert joiners and window specialists who made it their business to provide a professional and caring service - true craftsmen now retired and replaced by a jack of all trades decorator, who will cover your cords in white gloss and stick up your windows if you don't keep your eye on him.

Of course, there are still companies that do a fabulous job with maintaining and repairing sash windows, although few and far between, and for those who cannot bear to part with the original sash windows - this writer being a case in point - it is worth trawling the internet and researching referrals to find them.

But, in fact, these services are extremely expensive and it is estimated that a house of sash windows overhauled with draught-proofing will take five to twenty five years to recoup the cost in terms of energy savings. Only if the home owner is in it for the long term is this economically viable. Even then, the old windows provide fresh air and ventilation essential for a healthy environment which has prompted government guidelines on trickle vent installation into newly built properties to prevent condensation and rot. So too much draught proofing can cause other issues!

Nowadays we have the best of both worlds. There are some superb PVC sash window and aluminium sash window which is available in a huge range of colours and finishes and are very difficult to tell apart from timber. The advantages are numerous in that they really don't need to be maintained; they really do outlive the building's useful life and won't detract from the value of a property.

Timber sash windows can be built in any style of sash window required. And these timber sashes can be built featuring all of the new sash window security and sash window draught proofing technologies available. They can be built to match existing timber windows where the bother of refurbishment is simply not cost effective or where perhaps freedom from draughts or ease of use is essential.

Options include some nifty locking systems and child proofing to prevent accidents. Sash windows in any material can be built with a fire escape option to ensure no unnecessary risk of death in case of fire, and can conveniently open to allow access for cleaning in hard to reach areas, such as the second floor or attic conversion windows.

Luckily, the world of replacement window really has moved on. In this new era of throwaway, where everything has built in obsolescence, we no longer have enough craftsmen available to nurture or resurrect our period windows, so we are happy to dump them and start again. The sash window industry has finally filled that gap in the market with flexible, beautiful, robust products. Like me, hanging on to the heritage of solid timber may be the way you prefer to go, but just take a peep at the new materials and you may be pleasantly surprised.

If you’re looking for some nice, modern-looking and sleek doors that let in plenty of light, then frameless glass doors are the way to go. Frameless glass doors are usually best used as a shower “curtain”, or as a door that leads outside to the porch if you live in a fairly safe neighborhood.

They are wonderfully elegant and light, and look very contemporary; they also allow significantly more daylight into your home than a normal or even frosted glass door, and daylight has been proven to do wonders for your mood, and is shown to cure depression and increase productivity.

Frameless glass doors can be attached via hinges known as rails, so that the door is allowed to slide instead of opening outwards. The rails are either entirely along the length of the top and bottom, or can be applied using small patch fittings.

There are many frameless glass door manufacturers in both Europe and the United States. Some of the more popular ones include Hafele Glass Doors, Ozone Glass Doors, and Spaceslide.

Hefele is one of the most renowned manufacturers of frameless glass doors and creates a variety of frameless glass doors out of toughened glass anywhere from 8 mm to 19 mm thick.

There are three different types of fittings that you can choose to go with your frameless glass door. The A type is most common, with a rail at the top and bottom of the door to allow it to slide. The B type has a rail fitting at the bottom and patch fitting at the top, and tends to be a little more stable than C type, which has patch fittings at the top and the bottom.

However, patch fittings are a little more elegant and aesthetically more pleasing, so that is the trade off you will have to make if you choose it for your frameless glass doors.

Spaceslide creates standard sized frameless glass doors, unlike the more extravagant double doors that other companies make. These doors are for simpler, modern-looking homes and offices that are seeking a simple sophistication, and they come with the hinges, latch, keep plate, and handles.

You may choose a clear or smoked (which looks somewhat foggy) finish, and the nice thing about Spaceslide is that it will allow you to order custom frameless glass door sizes, in case one of your openings is not a standard size.

Ozone Glass Doors gives a wonderful new twist to the frameless glass door business, in that most of its doors are tinted with colored and textured glass.

Designs are contemporary and simplistically beautiful, and the company is fairly small, which allows you to be more on a personal level with its salespeople and order exactly to your standards.

The basic colors are grey, green, and bronze, though you can request a large variety of unique colors for your doors. You can choose whatever pattern you’d like on the glass, and they are created through the methods of mirror finishing, chromozone color, or sandblasting.

Replacing window glass begins with safety glasses and a good pair of work gloves. Replacing window glass or a broken window associated with an older window is something a homeowner can do with a few basic tools.

Start by removing the broken glass pane remnants still stuck in the window sash. You may need to use one of your pliers to help pull out any smaller pieces.

Next, remove the old glazing compound with your putty knife. Work your way around the entire window sash, in either a clockwise or counterclockwise direction, and scrape the old glazing compound out.

You may want to use a hair dryer to heat the glazing compound up. The heat will soften the old glazing compound and make it easier to remove. Apply heat to a localized section of the old glazing compound to soften it up, and then scrape it out with your putty knife. Keep stepping around the window sash in this process.

Also, in the process of removing the old glazing, remove any glazing points that may still be attached to the window sash. Use your Needle-nose pliers to remove the points.

After you have removed all of the glazing compound and glazing points, sand the area down to the bare wood to remove any old glazing compound or paint. Then apply a sealer to the bare wood to protect it.

Now install your piece of glass and place it into the window sash. Note that the glass should be slightly smaller than the window sash, e.g. 1/8th inch narrower in both length and width.

With the glass in place, install glazing points approximately every 4-6 inches, making sure you have a couple of glazing points near each of the corners of the glass. Be careful not to break the glass when doing this.

With the glazing points installed apply the new glazing compound to the window sash. It is best to roll out a ¼" string of glazing compound, and using your fingers and putty knife push it into place around the window edges.

Once you have pressed in the new glazing compound use your finger or a moist rag to smooth out the glazing compound and to clean the glass. Let the glazing compound dry overnight, and then apply paint to the window sash. When the paint has dried reinstall it into the window frame.

Composite material used for manufacturing composite doors. Composite doors become perfect choice for entrance.

Objects can be classified on the basis of material used for manufacturing. Engineered materials that are made up of more than one material of desired chemical and physical property are called composite material.

Composite mainly comprises of materials that can be classified as matrix and reinforce. The matrix material supports reinforce whereas reinforce material forms the structure an impart strength. Composite materials generally have high strength to weight ratio, this quality helps for applications where high strength is required at less weight.

The most common examples of composite material are fibreglass, carbon fiber, plywood etc. Fibreglass is made from fine glass fiber which acts as reinforcement material to polymers which act as matrix. Similarly GRP (Glass reinforced plastic) material is also used for manufacturing of doors.

According to the properties of GRP they render high strength, glossy effect due to glass though light in weight due to plastic. GRP doors also known as composite doors have high strength to weight ratio this makes it for the best choice for entrance doors which needs looks and security equally. GRP has all the desired property for an entrance door such as
  • Resistant to heat and water
  • No colour fading in sunlight
  • No expansion or warping due to moisture
  • No need to paint
  • As non conductor of heat so by structure it is energy efficient
  • Stronger in strength than wood though lighter than it
There is also other material door and window offer uPVC, PVC, PVCu. These clear advantages make it a perfect choice for entrance door with style.
