Dual Pane Vinyl Stc

Most window companies do not know much about noise.

Dual pane vinyl stc.

Sound transmission class stc ratings for glass vary from poor to practically soundproof. Single hung and picture windows are now available with a glass package that achieves an stc 35 while sliding windows achieve an stc 34. Single pane windows have an stc of 26 28 while double pane ones have 26 32 ratings. 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.

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. Single pane 3 8 averages 31 but could have an stc of 33 or 35. An insulated wall as a much higher stc rating than a single pane window. Single pane 1 8 has an stc between 21 and 28 and is commonly 27.

The typical rating for single pane windows is 18 20 while a double glazed window is 28 32. This glass package combines asymmetric laminated glass and dissimilar thickness glass within a 1 dual pane insulated glass unit to achieve improved sound performance. Double pane windows with dissimilar glass where the two panes of glass are different thicknesses can have even higher ratings. Single pane 1 4 has a sound transmission class between 30 and 32 and averages 31.

Double glazed windows and vinyl frames can help. 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. As you can see in the diagram indow inserts combined with a single pane window block noise better than an insulated wall. Glass by itself is a weak noise insulator but methods such as lamination or double glazing can improve performance significantly.

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. Triple pane windows have less space between panes of glass which actually works to their disadvantage when it comes to. The higher the rating the better the sound control. Standard monolithic or single pane glass is the cheapest option and works well for most interior applications.

Single pane 1 2 has a rating of 35 to 37 and is usually given as 36. Milgard quiet line windows can achieve an stc rating of up to. With stc rating the higher the score the less noise can penetrate. 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.

Dual pane windows will not stop noise.
