Double Glazed Windows

Double Glazing Windows Price and Features

Classic Window Replacements have introduced a range of high performance double glazed units; where with the inclusion of soft-coat Low E glass can achieve a centre pane U-value as low as 1.1 in double glazed units.

Our 28mm A-rated double glazed unit is made up of 4mm soft coat low E glass, a 20mm Thermex warm edge spacer bar which gives a thermal brake from the outside and inside glass panes and finally a 4mm low iron white glass.

All of our A-rated high insulation double glazed units are filled with Argon gas which adds another thermal barrier from outside elements.

Our process of sealing our units includes a dual PIB and Polyeurothane seal. This will insure our customers of premium quality, durability and argon-retention.

Our manufacturing unit is licensed by Pilkington Energikare.

Customer Reviews

  • Lisa Stutter

    We ordered in 2014 over 36 windows for our house and a townhouse of different sizes and styles. The windows are great, the savings on electrical has been awesome and the tint we got for the house is so good that no one can see into our house at night with light in the background! We are so pleased with our investment and the pricing was reasonable compared to others!

  • Mike Struffonilo

    They did a great job. Most reasonable quote of 3 and got it done in a timely manner. Then when I needed additional windows, they came back out and did those quickly. Great Experience and highly recommend.
