Double Glazing Glasgow, Glasgow Window Company

If your Glasgow home still has older single glazed or worn out double glazed windows, a surprising amount of your heating budget is going straight through the glass every winter. Draughty frames, failed sealed units, and condensation between the panes are all signs that your windows are working against you rather than for you.

Heating a home with poorly performing windows can add a significant amount to your energy bills year on year. That heat you are paying for is escaping through gaps in the frames, cold glass surfaces, and seals that have long since broken down. Over a few winters, that adds up to a real cost that new windows and doors could have prevented.

A Rated Windows and Doors Make a Noticeable Difference

All the windows and doors we install here at Glasgow Window Company carry an A or A+ energy rating. That rating is not just a label. It reflects how well the unit retains heat inside your home, which means your boiler does not have to work as hard to keep rooms at a comfortable temperature. Modern double and triple glazed units use low emissivity glass coatings and argon gas fills between the panes, both of which slow heat transfer considerably. You will feel the difference on a cold Glasgow morning, rooms hold their warmth for longer and cold spots near windows become far less noticeable.

New Windows Cost Less Long Term Than Repairing Old Ones

Old windows tend to become a maintenance drain. Seals fail and let moisture in, hinges and handles wear out, frames warp and stick, and misted glass units need replacing individually. Each repair call costs money, and none of those fixes actually improve the thermal performance of the window itself. Replacing with a quality uPVC or composite unit removes that cycle of ongoing repair costs. The frames we fit are virtually maintenance free, they do not rot, they do not need painting, and they will not warp over time. Every installation also comes with a full ten year guarantee, so if anything does go wrong you are covered.

Six Ways New Windows and Doors Save You Money Over Time

  • Lower heating bills as A and A+ rated units retain far more heat than older glazing
  • No repainting or restaining costs as uPVC frames stay looking good without annual maintenance
  • Fewer repair callouts because modern multi point locking mechanisms and quality hinges are built to last
  • Better home security reduces the risk of break ins and potential insurance claims, multi point locks and toughened glass come as standard
  • Reduced condensation and damp means less chance of costly mould or plaster damage inside your home
  • Added property value as buyers notice quality windows and doors, and energy efficient homes carry more appeal in the current market

Our Current Sale Gives You the Best Time to Buy

Glasgow Window Company is currently running a sale across our full range of windows and doors, including uPVC windows, composite front doors, French doors, patio doors, and triple glazing. This is a genuine reduction, not a price that has been artificially inflated beforehand. If you have been putting off replacing your windows because of the cost, this is a good time to get a quote and see what the actual numbers look like for your home. We offer free, no obligation quotes with no pressure to make a decision on the day. Our fitting timescales run to around ten weeks from order to installation, so if you want new windows in place before the worst of the winter weather, getting in touch sooner rather than later makes sense.

Our team covers Glasgow and the surrounding areas, and we have completed projects right across the city with a strong track record of five star reviews from homeowners who came to us with exactly the same concerns you might have now. Give Glasgow Window Company a call today on 0141 310 9808 and we will put together a free quote for your home.
