Thermal curtains are more suitable for room temperature control than vertical blinds. The insulating features of thermal curtains make them a popular addition in many homes. However, several techniques can help make vertical blinds more energy efficient.
How Insulation Works
Air has excellent insulation properties. Air trapped between two layers of vinyl or fabric provides better insulation than the same air trapped between a single layer of vinyl or fabric. Therefore, window treatments containing more than one layer are better insulators than those with a single layer. The more the number of layers in a window treatment, the better insulation they provide.
R-Value: Measurement for Insulation
The ability of an object to resist heat flow is referred to as R-value. Items or objects with higher R-values provide better insulation and vice versa. Most insulation materials used in today’s homes have R-values of more than 40. However, it is important to know that not all window treatments have a rated R-value.
What Makes a Blind a Good Insulator?
Window blind’s R-values are influenced by two main features. Firstly, additional layers translate to more insulating ability. Blinds that have vanes with pocket air in the middle will insulate more than vertical blinds made of a single layer of fabric or PVC vinyl. Another feature that affects R-value is the tightness that the blind has against the window.
What Makes a Curtain a Good Insulator?
Just like window blinds, the R-value of a curtain is determined by the quality of the fabric a thermal curtain if made from and the number of layers it has. Most thermal curtains have several layers and are therefore, good insulators. Another factor that affects curtain insulation is its window fitting. The curtain’s ability to sufficiently insulate a room is lowered by the presence of gaps around the edges of the window. Consider choosing curtains that fit perfectly around the sides of your windows. Window draperies and quilts can hold an R-value of between three and five.
Heat may be lost in a room due to poor insulation of doors and windows. Weather stripping and caulking can help reduce this problem. Single paned windows have less insulating values than double paned windows. Insulating blinds and louvers can enhance insulation in a room, but cannot stop air from leaking into or out of a room. This can only be solved by weather stripping or caulking.
