The terms 3% and 4% often relate to the percentage of the anchor bolt’s yield strength in relation to the concrete’s compressive strength. For example, a 3% concrete anchor bolt means that the bolt can withstand loads up to 3% of the concrete's yield strength, while a 4% bolt can handle loads up to 4%. This distinction is vital for engineers and contractors, as it influences load calculations, safety factors, and the overall design of the structure.

  • According to the regulations, from 2021 onwards, the Uw value of a vertical window must not exceed 0.9 W/(m2*K). However, it is worth mentioning that each of the two basic elements that make up a window, namely the frame and the glazing, have a different thermal transmittance. Consequently, the thermal transmittance of the glazing Ug is lower than that of the profile Uf, which makes the glazing a warmer window element. Uw is, in turn, only the resultant of the two values we mentioned.
