Window Frames | 4 Smart Frame Materials For Thermal Insulation in Your Home

Windows are a key element of every room in the home, because they control the level of natural light in the room. Apart from their natural light regulation, they can also control the thermal resistance in every room. Thermal resistance through a frame can improve the energy efficiency of windows. However some framing materials, like aluminium and metal frames, provide poor thermal insulation, so they are not an ideal choice for internal windows. Here are some smart window frame materials for better thermal insulation in your home.

Composite Frames for Windows

Composite window frames are made from different wood products like strand lumber and particleboard. They are brought together closely to form a stable frame structure with excellent insulation and thermal properties. Composite window frames also have good moisture and decay resistance, making them a good choice for windows subjected to heavy rains and cold winds. They work particularly well in areas affected by severe weather, making them a practical frame choice for any window in your home.

Fibreglass Frames for Windows

Fibreglass window frames come with a stable and strong structure. Their air cavities can be easily insulated to offer superior thermal performance in any room. Fibreglass frames are a relatively new choice for windows, but they are rising in popularity for their ability to retain cold internal temperatures in summer and warm internal temperatures in winter. Fibreglass is considered to be one of the most thermally efficient materials for window frames.

Vinyl Frames for Windows

Vinyl window frames are usually made from high-quality polyvinyl chloride (PVC) materials and are highly stable structures that do not break down in intense sunlight for long periods –– this makes them an excellent choice for internal and external windows. Vinyl frames are resistant to moisture, so they can be placed against windows subject to heavy winds and rains. Any hollow cavities are insulated to offer good thermal protection for your home.

Wood Frames for Windows

Wood is perhaps the most common and aesthetically pleasing material for window frames. They provide good thermal protection and insulation, but they also expand and contract with heavy moisture and extreme weather conditions –– this makes them unsuitable for windows subject to heavy rains and winds. Wooden window frames also require more maintenance and cleaning than vinyl, fibreglass or composite frames, but they deliver superior decorative appeal in comparison to their counterparts.

Choosing the right frames for your windows will depend on the level of external conditions –– use this guide to help you when choosing frame materials for different windows in your home.
