The Benefits of uPVC

From Value to Durability, find out why PVC-u quickly became the nation’s favourite

One of the important factors you need to consider when installing new windows is the material with which the frames will be made. Over recent years, the use of PVC-u has grown hugely in popularity and is now one of the most widely available materials on the market.

Below are the pros and cons to using PVC-u over its alternatives of aluminium, timber, hardwoods and softwoods:


Due to its resilience and strength, PVC-u is very dependable when it comes to security. The frame is both very strong and hard, making it extremely damage resistant and highly burglar proof, second only to aluminium frames.


When it comes to choosing a material the first thing to note is the cost, Timber generally being the most expensive, then Aluminium, then PVC-u. The added advantage of PVC-u is the low maintenance cost, with no need for sanding and staining you’ll be saving on care products and time.


PVC-u was created with insulation in mind. It surpasses both timber and aluminium frames in this respect and is the best at keeping warmth in and noise out. Plastic is an excellent insulator by nature, and the multi boundary design of PVC-u units lends it extra acoustic insulating properties.


PVC-u is an inherently inert material, this property coupled with its hardness gives it the best durability of the available materials. Unlike wood products, PVC-u does not rot, warp or peel and unlike aluminium it does not rust. Also there is no problem with sap extrusion or breathability. We are so confident in the quality and longevity of our PVC-u frames that we offer a ten year guarantee.
