U-values play a crucial role when it comes to windows and the energy efficiency.  The U-Value of window represents its overall thermal transmittance, taking into account the frame, glass and other components that make up the window. Windows with lower U-values provide better insulation and reduce heat loss or gain.Various factors influence the U-value including, Glass type, coatings, spacers, frame material and window design.Our windows are double paned with warm edged spacers, have Low-E Coatings and filled with Argon.  Achieving a low U-Value for our customers.  It is important to note that U-value’s change when you change elements of your window design our team will be happy to advise you on this when choosing your window.

Whilst replacing your windows can help to reduce noise transmission into a building and improve sound insulation it is important to note that there are specific types of glass that are manufactured specifically to reduce noise. If you have specific noise reduction requirements then please speak to the team when you are making your enquiries. There is a helpful section in the glass area of this website to give you more information. You can find it here

Trickle vents are small openings installed in windows and doors to provide controlled ventilation and air exchange within buildings. These vents allow a continuous flow of fresh air into the building, even when windows and doors are closed, helping to maintain indoor air quality and prevent issues like condensation and mold growth.In line with the new rules, anything installed after 15 June 2022, all windows and doors must be fitted with trickle vents, unless there is an alternative, dedicated ventilation system fitted. This includes windows and doors in newly built homes, windows and doors in newly built extensions, as well as all replacement windows and doors, regardless of whether they have trickle vents currently or not.All windows and doors must comply with the new building regulations and is requirement of the law.  Unfortunately there is no choice – you have to have them.

Condensation forms on windows when warm, moist air comes into contact with a cold surface. This phenomenon occurs because warm air can hold more moisture (humidity) than cold air. When warm, humid indoor air comes into contact with the cold surface of a window, the air cools down. As it cools, it loses its ability to hold moisture, leading to the excess water vapor turning into liquid water, which appears as condensation on the windowpane.

If condensation has formed on the inside of your window, this is perfectly normal. In fact, this is a sign that your windows are working properly so you shouldn’t be worried that your new windows have condensation. This is because double glazing reduces the amount of heat transmittance from one side of the glass to the other, this creates a massive difference in temperature form one side of the glass to the other.  The warm air within your house meets the cool surface of the window which creates moisture.

How to reduce condensation?

  1. Ventilation is the key – open windows and doors when weather permits especially in moisture prone rooms like kitchens and bathroom.  Keeping trickle vents open all year round will help combat condensation.
  2. Ensure warm air circulates freely around your home.  Avoid obstructing radiators and vents with furniture and curtains.
  3. Avoid drying washing inside – if necessary, use a well-ventilated, airy room.
  4. Where moisture is a problem the use of a dehumidifier can significantly lower indoor humidity levels.

If you are experiencing moisture between your window panes that this as an indication that your window is failing and it might be time to replace it.  A survey from our Alpha Windows team will help you establish if this is required.
