Dual Pane Vinyl Stc

Single pane windows have an stc of 26 28 while double pane ones have 26 32 ratings.

Dual pane vinyl stc.

This glass package combines asymmetric laminated glass and dissimilar thickness glass within a 1 dual pane insulated glass unit to achieve improved sound performance. Single pane 1 2 has a rating of 35 to 37 and is usually given as 36. Glass by itself is a weak noise insulator but methods such as lamination or double glazing can improve performance significantly. Single pane 3 8 averages 31 but could have an stc of 33 or 35.

Sound transmission class stc stc is used to measure a window s ability to reduce sound. An insulated wall as a much higher stc rating than a single pane window. Most window companies do not know much about noise. Double pane windows with dissimilar glass where the two panes of glass are different thicknesses can have even higher ratings.

In fact dual pane windows with dissimilar glass can achieve stc ratings nearly as high if not as high as triple pane or laminated glass. Single pane 1 4 has a sound transmission class between 30 and 32 and averages 31. Single hung and picture windows are now available with a glass package that achieves an stc 35 while sliding windows achieve an stc 34. With stc rating the higher the score the less noise can penetrate.

Sound transmission class stc ratings for glass vary from poor to practically soundproof. Read the definition of stc rating. Triple pane windows have less space between panes of glass which actually works to their disadvantage when it comes to. Standard monolithic or single pane glass is the cheapest option and works well for most interior applications.

Single pane 1 8 has an stc between 21 and 28 and is commonly 27. At jeld wen for example we offer a variety of dissimilar glass combinations on our vinyl windows that carry up to an stc 34 rating. Double glazed windows and vinyl frames can help. As you can see in the diagram indow inserts combined with a single pane window block noise better than an insulated wall.

When good thick dual pane windows rated at stc 35 are installed replaced existing single pane windows with stc 27 the sound will not be reduced much. The higher the rating the better the sound control. Often until the stc rating is up in the 40 s the noise is not reduced enough to stop it from being a significant problem. In the third test where the results are almost identical the vinyl frame is substantially thicker and is probably the reason for the good performance.

In the second test the inherent problems of dual paned glass likely contribute to degrade the vinyl window performance.
