Window FAQs

How long do uPVC windows last?

Anglian windows are manufactured to British Standards. Our uPVC windows last around 20 years. If your uPVC windows are showing signs of cracking or chipping then your windows may need replacing sooner. We guarantee our window frames for 10 years and the sealed units for 15 years. If your Anglian windows show signs of damage before then, you can get them replaced under your guarantee.

How much does it cost for double glazing?

How much does it cost for double glazing? It’s difficult for double glazing companies to provide a fixed cost for double glazing, as the price will depend on the individual requirements and specification of the home. We provide a bespoke window fitting service, so the price is bespoke too. Request your quote here.

Is triple glazing better than double glazing?

With the highest energy rating possible of A++, triple glazing is the most energy-efficient glazing option on the market. It is at least a grade higher than double glazing. Triple glazing is made from two panes of Low E glass and one pane of Low Iron glass. It is the best option for your home if you want to retain the maximum amount of heat and block out noise.

What is the difference between PVC and uPVC?

PVC is a lightweight plastic that has special plasticisers added to it to increase its flexibility. It is used in a variety of everyday materials including packaging, electronics and even clothing. uPVC has no plasticisers added to it, so is strong and rigid. This makes it a great material to construct windows from.

Do coloured uPVC windows fade?

uPVC windows are durable, hard wearing and low maintenance. If correctly maintained in accordance with the manufacturer's instructions, there should be no noticeable fading to uPVC windows within our 10-year guarantee.
