We recently had new upstair windows fitted to our property. The fitters arrived at 8.30 in the morning and left, having cleared up all the mess at 5.30pm. The guys were very friendly and did an excellent job.

Our Frequently Asked Questions

Here are some of our frequently asked questions by our customers.

Double-glazed windows and doors are made up of two panes of glass with insulation gas, such as krypton or argon, in between each piece of glazing. Replacing your old windows with double-glazing offers several benefits to both household and commercial property owners.

  • Double-glazed windows provide improved insulation by using gas between the panes to slow the transfer of heat from inside to outside. This helps to keep the property warmer and can prevent up to 30% of heat loss during the colder months. Installing double-glazed windows is a solution to combat the problem of heat loss in Peterborough properties.
  • Double glazing is a recommended home improvement as it is energy efficient and can save you money. It helps trap heat inside, reducing the need for excessive heating and resulting in lower bills and a more comfortable home temperature.
  • The new windows and insulating gas reduce noise pollution, providing a peaceful and comfortable environment.
  • By reducing the moisture on windows can also decrease the occurrence of mould and other allergens, which can affect vulnerable individuals.
UPVC Windows are made from durable plastic that is highly resistant to weathering. They do not rot, warp, or corrode, making them a cost-effective and secure option for improving thermal efficiency in homes.
The Optima system used in our windows is highly efficient, with low U-Values and high Window energy ratings. This reduces the need for central heating and decreases a property’s carbon footprint. It is an effective home improvement. As fabricators, we prioritise thermal efficiency. We strive to reduce our own carbon footprint and energy consumption. We also focus on recovering and recycling manufacturing waste and materials from end-of-life products.
We offer new windows with the Optima profile. These windows meet high security standards. They have a high-security multi-point locking system and are internally glazed. This prevents burglars from removing the pane from the outside. The uPVC profile is durable and strong. It can withstand uninvited visitors. The Central Eurogroove in the profile gives the sash greater rigidity. Our Window Locking System is Secured by Design as standard. It includes dog bolts to the hinge side of the window and appropriate glass where needed.

KLIC Home offers a variety of colour options for our casement window range, including multiple foil and colour options. We also have an in-house spraying booth to ensure all windows, doors, and ancillary items match perfectly.

Additionally, we provide a diverse selection of styles including:
