Norwich Double Glazing Windows - Strong, Safe, Secure

KLIC Home locking systems are Secured by Design. All components have been purpose designed and selected to ensure the performance of the finished product can surpass all standards laid down for enhanced security and is also durable, long-lasting and pleasing to the eye.

Locking points that secure the window in all four corners and sides of the frame, and an internally glazed design that prevents the glass from being removed from the outside.

Installing KLIC Home ‘A’ energy-efficient windows can significantly improve the sound quality in your home. With high-performance glazing, sound resistance is enhanced and a higher quality of air, noise and light filtration is achieved – ultimately providing you with a more comfortable internal environment.

Our energy-efficient windows cut heat loss through windows and can significantly reduce fuel bills for householders. Just by reducing the running time of your heating system and locking in thermal energy, you can achieve a warmer, healthier home.

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 refer to a type of construction within windows. They consist of two panes of glass as opposed to one, and between the two panes is insulation gas – krypton and argon. These make perfect new windows to replace your old ones for several benefits:

  • Improved Insulation – The insulation gas between the two panes works by having gas that slows the transfer of heat from the inside to the outside, meaning that your house stays warmer as a result. It’s estimated that up to 30% of a household’s heat is lost through your windows during winter – a potential problem with the Norwich weather. Avoid this by installing double-glazed windows to keep your home warmer.
  • Energy Efficient – Double glazing is a highly recommended home improvement due to how it can save you money through its energy-efficient properties. By trapping your heat inside, you spend less on heating replacing the heat you lose. This can result in reduced bills, and a more comfortable temperature for your home.
  • Noise Reduction – Your new windows and the insulating gas within does not only slow the transfer of heat, but it acts as a barrier against sound. Noise pollution will be dampened when it reaches your window, allowing you to leave your house in peace and comfort.
  • Reduced Condensation – By reducing the moisture of your windows, you can also reduce the amount of mould that appears in your house as a result, alongside other allergens that may affect vulnerable parties.

UPVC Windows refer to the construction within the frames of a window and are made of rigid, durable plastic that is highly resistant to the weather. It does not rot, warp, or corrode. Amongst home improvements, uPVC windows and doors stand out as cost-effective options that offer thermal efficiency and a high level of security.

Yes, and in more ways than one! The Optima system excels in thermal efficiency, giving U-Values as low as 0.9W/m2K and Window Energy Ratings of up to A+. This will lead to less need for central heating and reduce the property’s carbon footprint, making them incredibly effective as far as home improvements go. As fabricators, we believe it’s important to provide a thermally efficient product. That’s why we’re committed to reducing our own carbon footprint, delivering increased efficiency and reduction in our energy consumption. We are also committed to recovering & recycling manufacturing waste & materials generated by end-of-life products.

By using the Optima profile, we can offer new windows that meet the highest standards of security. Our windows and doors are fitted with a high-security multi-point locking system and is internally glazed, preventing a burglar from removing the pane from the outside. The uPVC profile itself is durable and strong, standing tall against uninvited visitors. The Central Eurogroove within the profile gives the sash greater rigidity. Our Window Locking System is Secured by Design as standard with dog bolts to the hinge side of the window and appropriate glass where applicable.

KLIC Home is able to offer our casement window range in a variety of different colours. We offer multiple foil and colour options including our own in-house spraying booth which can ensure all windows doors and ancillary items match perfectly.
