Dormer windows: Tips to maintain them in any climate

To prevent heat gain, moisture gathering, and severe weather damage, install your dormer windows (Dakkapel Helmond) according to these guidelines for proper ventilation.

Install windows that fit

The terms “nominal” and “real” refer to two distinct types of window sizes. The amount of natural light let into the attic is directly proportional to the size of the window in a dormer.

Nominal measures, or those suggested by the manufacturer, are used to describe the sizes of windows. It’s more likely that actual size windows will fit in your home’s walls, but they may be more expensive.

Window insulation against heat gain

If the windows are south-facing and it gets really hot outside, heat will escape via the roof and sashes. Windows need to be insulated against heat gain to avoid heat loss from the inside of the house to the outside. Insulating your dormer windows with weather stripping that is half an inch thick can prevent warm air from rising through the windows and into your attic. Insulation on all four sides of window panels is necessary to stop them from being warmed by rising warm air.

Utilise crown moulding and complete the trim

Crown moulding and a vapour barrier applied to the completed window trim will prevent condensation from forming. A vapour barrier will help prevent condensation and keep out moisture if your windows are in a high-humidity area.

Employ weatherstripping

Certain windows may be affected by rain, but any window can be damaged by wind. To prevent broken windows due to wind, weather stripping should be installed around each one.

Guarantee the safety of exposed edges

Dormer window framing should be securely attached and covered to prevent injury or property damage. These edges pose a threat to your home’s integrity because water can seep into the foundation if the gap is not properly sealed.

During storms, protect dormer windows with shutters

Dormer windows provide welcome relief from the heat, but they can also cause serious damage during a storm if they aren’t protected properly. Protect your home by closing the dormer windows before a storm hits. Covering the window permanently would prevent fresh air from entering, thus you shouldn’t do it. Plywood at least 1/2 inch thick can be used to permanently seal the window. Insulation sheets made of fibreglass can be used as well.

Insulate window frames properly

The window frame needs to be well-insulated to prevent damage from severe weather. You should insulate around the outside of the frame rather than up against the wood trim. Moreover, the space around the window frame needs to be insulated by adding 1" of fibreglass or a similar material.
