Scotland changed its building standards in March 2003 requiring the highest performance windows in dwellings ever requested. Under Part J of the Building Standards Code, new construction and replacement windows must meet strict specifications. Double glazing highland windows not only meet, but exceed these requirements, but selecting the right company for the job may take a little understanding of what the new regulations mean to homeowners.

One of the main features that is changing this industry in Scotland is the fact that windows and doors must have a u-value 10% lower than that found in either England or Wales. This measurement analyzes the heat loss from a dwelling. The lower the u-value found, the better the performance of the windows and doors. This can save homeowners a tremendous amount of money on utility bills in the long-run.

Compared to prior years, this new value means that windows and doors made of plastic or wood need a u-value of no more than 1.8. If constructed of metal, the u-value cannot exceed 2.0. The only exception to this new rule is with homes designated as historical landmarks. In order to keep the authenticity of the original design, windows and doors consistent with the period may still be used.

Another exception is for those who have recently installed central heating boilers that utilize energy-efficient gas or are oil fired. However, these exceptions are very rare and to be sure, a glazing installer needs to be consulted and a written confirmation needs to be obtained prior to the time a decision is made.

For those who attempt to install windows that do not meet the new standards, they will more than likely find problems when selling the property. With the use of a glass analysis gauge, a surveyor can establish the exact u-value and determine whether or not the glass used meets the specifications required by law. A house will remain unsellable until this problem is corrected.

Although building control approval is not required, if not done correctly windows and doors may have to be replaced by a certified technician. According to the Scottish Technical Standards Building Regulations, these portals must contain an emergency escape feature, be constructed of safety glass, provide ventilation, and be safe-cleaning. This means that glass can be knocked out easily without shattering.

It’s important to remember that even new additions and remodels fall under the new guidelines. In this case, however, drawings and specifications also need to be approved by the local council prior to the commencement of work. By contacting the local Building Control Officer and requesting a copy of the GGF 2.2 data sheet, one can determine exactly what is needed when installing or replacing windows and doors.

One way to circumvent the confusion about the new regulations is to hire a qualified and certified glass technician who specializes in the installation of double glazing highland windows and doors. Whether one opts for internal glazing, which has the advantage of no beading on the outside, or external, which locks the beading into place, the right window manufacturer will ensure that any dwelling is safe, secure, and meets the new regulations mandated by the government.
