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 are some of the best home improvements available for homes across the UK. Unlike single-pane windows, double-glazed windows come with a massive amount of benefits.

Here are the things you can expect from your double-glazed windows:

  • Improved Insulation – A double-glazed unit comes with a space between the two window panes. Within these panes is an insulated gas, such as argon and krypton. This gas prevents the transfer of heat from inside your home to travel outside. As such, this means that more heat is retained in the home – something that’s especially useful in Norwich.
  • Energy Efficiency – With the heat of your home escaping through single-pane windows, you are essentially paying more through heating to replace that energy lost, or even simply not feeling the benefit of the heating you pay for due to it all being lost through inefficient insulation.
  • Noise Reduction – The extra layer of glass, as well as the insulating gas within the double glazing, creates a sound screen that dampens the noise pollution outside. This is particularly useful if you live in a place with a lot of hustle and bustle, such as Norwich City Centre. This reduction in noise means you can enjoy your home in the peace you deserve.
  • Enhanced Security – Double glazing is a lot stronger than single-pane windows. Not only do they have an additional pane of glass, but the frames are built to be sturdier than the average window pane to embolden the effects of noise cancellation and energy insulation.
  • Reduction in Condensation – Due to the high-quality window frames that double glazing comes with, you can expect to see minimal to no condensation at all on your windows. This keeps your home dry and reduces infestations of mould. This is particularly useful for those sensitive to allergens.

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.
