Wood windows to keep you warm this winter

Fri 20 Nov 2015


The last couple of winters have been exceptionally mild in the UK. But, according to Met Office predictions, this year’s El Nino phenomenon could lead to a colder and snowier winter than usual, similar to ‘The Big Freeze’ of 2009/2010. That was the coldest December since records began.

This will mean a struggle to keep warm for those still living with single-glazed windows, not to mention the draughts and condensation. Yes, drawing heavy curtains at night will help, or you could install secondary glazing, but the best solution is replacement windows.

To give you an idea of the difference in energy-efficiency of single, double and triple-glazed windows, you would expect a typical single-glazed sliding sash window to have a u-value of around 5.4W/m2K, compared with around 1.4 for double-glazing and 1.0 for triple-glazing.

Will fitting modern double or triple-glazed windows save enough on your fuel bills to pay for themselves? No, not at current fuel prices.

Will they make a difference to the comfort of your home? Absolutely. You’ll have a warmer, draught-free home and the added benefit of lower fuel bills. Modern double or triple-glazed windows make a real difference to the way a house feels, eliminating draughts and cold spots; giving your heating a chance to get your home comfortably warm.

The right replacement windows will also add value to your home

PVC-u or wood? There’s no question that PVC-u is the cheaper option, but, particularly for people living in a period house, wood is likely to provide better long-term value. Not just because high performance wood windows will last twice as long as PVC-u, but also because they will maintain the character of your home, adding to its desirability and value. A national survey of Estate Agents carried out by English Heritage found: ‘Unsympathetic replacement windows and doors, particularly plastic/PVC-u, are the single biggest threat to property values in conservation areas.’
