Glass can also be heat-strengthened or laminated, to make it more shatter-resistant. Laminated glass is a combination of two or more glass sheets with one or more interlayers of clear plastic or resin.
A single-glazed product has one pane of glass; a Retrofit Double Glazed Doors product has two panes sealed together with a spacer bar around the edge; a triple-glazed, three; and a quad-glazed, four. There are four factors that affect heat flow resistance due to double glazing of doors: the type of glazing material, the size of the air space between the layers of glass, the thermal resistance or conductance of the frame and spacer materials and the “tightness” of the installation.
Advantages of Retrofit Double Glazed Doors include:
- It provides improved insulation which enhances warmth in winters and coolness in summers.
- It reduces heating costs by heat retention. Thus energy costs are lowered. It translates into a saving of at least 10-12% of the energy cost (to heat the room spaces) over a room that is not fitted with Retrofit Commercial Doors.
- It provides noise reduction and thus you are facilitated with a relaxing and peaceful environment.
- Condensation problem is largely overcome. Condensation forming on the inside of the glass within the space not only looks unappealing and dirty, but can over time cause degradation to paint and varnish work.
- A special UV ray inhibitor is included in double glazing which filters out up to 85% of harmful UV rays that cause rot and fading to carpets and furnishings.
Retrofitting-Replacing existing timber or aluminum doors with lower transmittance units provided by double glazing is the simplest and the most effective form of energy a Retrofit Double Glazed Doors. If you have perfectly sound door frames then you only need installing a new door into the frame of the door being replaced.
Retrofitting is only feasible under certain conditions:
- The existing frames must provide sufficient levels of transmittance, functionality and air-tightness to justify their continued use. It is important to bear in mind that installing double glazed panels doubles the weight of the glass, thereby increasing the load on the corner joints of the sashes and on the operating hardware
- To provide acceptable thermal performance, the new double glazed panel must have a thickness at least 4-6 times greater than that of the old glass, making it necessary to increase the size of the rabbets and to alter the glazing beads.
Benefits of Retrofit Double Glazed Doors:
- It is quick and simple to perform as it involves reuse of existing door frames and also reduces glazed surface area.
- A retrofit is usually less expensive and minimizes the disturbance to the surrounding wall and trim.
- It also narrows a door opening and reduces the glass area of a window by about 10 percent.
Thus, in order to enhance the insulation comfort level of your home it is most appropriate to opt for retrofit double glazing as a cost and energy-efficient choice. front doors bridgend
