In the final instalment of our series on what to consider when choosing a roof window, we look at durability and the importance of selecting a product that can stand the test of time. One lucky reader will also win a break away for two courtesy of Dakea.
As with every part of the building, the type of roof window you select and the materials used in its construction can have a significant effect on the ease of maintenance, longevity of the product and, in turn, the long-term costs for the homeowner.
There are a number of environmental factors that will affect the lifespan of a roof window. These include rain, wind and freezing temperatures as well as exposure to ultraviolet (UV) radiation from sunlight. In addition to the external elements, factors such as the humidity of the room will have an impact of the life of the window.
For example, the moisture of the air in the kitchen will lead to a higher level of condensation in the room generally and on the inner surface of the window specifically. If the interior of the window frame is not adequately protected this can cause damage that is costly to repair. These forces will eventually degrade the window frames and seals to the point where replacement is necessary.
As with many areas of the building it can be tempting for homeowners to opt for cheaper alternatives when replacing windows. However, choosing a product with greater durability is far more cost effective in the long term by extending the time between replacement work. This is especially important where customers are planning to stay in the current home for a number of years.
Analysis has shown that aluminium clad timber frame windows have a typical lifespan of up to 60 years. The carefully controlled conditions in which modern factory-finished timber windows are produced provide a high quality construction and long-term durability.
When selecting a timber window, in addition to the performance factors, the main areas that should be considered are the material used, the coating and the quality of the build.
For example, Dakea’s Ultima roof window is constructed from carefully selected, Forest Stewardship Council (FSC) certified Nordic Pine. This type of wood has a naturally high density and excellent durability due to harsh winter conditions the trees grow in.
The timber also undergoes an advanced treatment process, which includes de-moisturising the wood to protect against deformation of the frame. A specialist double layer coating is then applied to the wood. This lowers the maintenance requirements as it creates a more durable surface and significantly extends the time before re-lacquering is needed.
The durability of Dakea Ultima is backed up by a 20-year homeowner-to-homeowner transferrable guarantee that gives installers and customers peace of mind.
With a range of factors to consider when selecting a roof window for a customer, it is essential to know the important areas to look at. Helping homeowners to make the right decision and providing the best possible service can help you grow your business.
