Are you having trouble deciding the window frame? Are you aware of the importance of the window frames? Window frames are an essential component of every window as it can affect the energy efficiency. To improve the strength, a window frame works with the glazing element to affect the efficiency. Most of the energy efficient window frames are made from materials that will not transfer heat or cold.
The double glazing window is situated within a frame, so you must be careful when selecting the quality of window frame. The quality of the frame will affect the insulation properties of the double glazing window. The most commonly used window frames are made from timber, aluminium, and PVC.
Here is the list of most used window frames that might help you decide which frames to choose.
AluminiumAluminium double glazing window frames became popular during the 1970s in the UK. These are not used widely because of the high cost and poor insulation properties. Aluminium frames have some benefits as they are strong, secure, have long life expectancy and requires less maintenance. They are best-suited for situations where there are strong sunlight and humid weather. Aluminium is lightweight, they can hold heavy pieces of glass. This means that the large windows do not have to be split into various window panes.
Wooden FramesTimber frames are made from various hardwood and the most commonly used frame is from tropical mahoganies like meranti. They are durable and attractive along with this, it provides a traditional look to the house. However, they have more maintenance requirements and are costly.
Moreover, some hardwoods like oak or beech are more expensive. But allow a better finish and great flexibility. An important tip to keep in mind when selecting the timber is to make sure the wood have been dried properly. If the wood is not dried completely then it might cause problems of cracking or shrinking in future.
Furthermore, other factors of the wood must be taken into accounts like the thickness, straightness, and grain. These will affect strength and resistance of the double glazing window. Timber frames make a great pick because they are low thermal conductors that make them excellent insulators.
PVC FramesIn recent times, PVC frames are most commonly used as they are low-cost option. They are the best pick because they are excellent insulators as the cavity between the frames is filled with insulating material. They are versatile regarding the shape, size, and colour. They can be moulded into various shapes which mean they are suitable for most of the window shapes. PVC frames require little maintenance.
However, they are not as strong as metal or wooden frames. PVC can suffer from expansion when under direct and strong sunlight. In case, extra resistance is required they can be protected with galvanised steel. It might reduce the thermal efficiency of the double glazed windows.
Therefore, replacement of standard window with double glazing window is a project of home improvement. The frames are very important part of window as they affect the energy efficiency of the whole window.
