Concrete basics for building: Concrete floors for domestic applications

We expect concrete floors to last for many years, despite heavy loads and hard wear.

Pay special attention to foundation material, the thickness of the slab and the strength of the mix, and provide joints to allow for contraction. And cure the slab well. This, as well as proper batching, mixing, transporting, placing and curing will ensure that high quality is built in at the outset and that future trouble and costly maintenance will be avoided.

Windows and heat loss

Windows have a considerable impact on a building’s energy use, because glass is significantly affected by solar radiation and airflow, outside and indoor temperatures, wind and occupant use. As a result, it is important for the window industry to understand how energy efficient a window is by measuring its thermal transmission, known as its U-factor. The U-factor is simply described as the rate of heat transfer through a window. The lower the U-factor, the lower the heat loss, and the better the window will insulate a building.

Everything you need to know about circuit breakers

Electrical contractors and builders, do you know how circuit breakers work?

Circuit breakers are an essential element of modern homes because of the safety they provide. These devices are automatically-operated electrical switches which have been designed to protect your electric circuits from damage due to an overload or a short circuit. A circuit breaker identifies a fault and then interrupts the flow of current in order to avoid overheating appliance wires, and possibly causing a fire.
