  • Sticking During Hot Weather 
  • Failure to Open from the Inside or the Outside 
  • Windows/Doors Sticking in the Locked Position 
  • Not Opening at the Top or Bottom 

The good news is that when any of these issues occur, our double glazing Eastleigh team can visit your home to put things right. We have plenty of experience as double glazing installers and just as much experience fixing double glazed windows and doors.

How Much Does Double Glazing Cost

Benefits of Double Glazing

If you’re considering replacing your current windows, we strongly recommend that you give The Window Company a call, especially if your windows are single-glazed. Single glazing is woefully ineffective at keeping a property warm or preventing damp ingress, only serving as a simple barrier against the elements. 

Even if your property has double gazing, Eastleigh customers, consider how old your windows and doors are. Predictably, doors and windows become less effective with age. But more importantly, technologies have improved, and the modern designs available now are far more efficient than older double glazed doors and windows. 

Modern double glazing is designed with a gap of 16mm between two glass panes (something single glazing lacks for obvious reasons). An inert gas, usually argon, xenon, or krypton, floats within this gap. It’s this gas that helps to reduce heat transfer, slowing the rate of heat loss. 

Here are a few reasons why modern double glazing would be a wise investment, especially with winter on its way: 
  • Energy Efficiency 
  • Noise Reduction 
  • Increased Security 
  • Less Condensation 
  • Better UV Protection 
Double glazing traps warm air better than single glazing, slowing heat transfer which results in a room retaining its temperature for longer. This translates to less energy used in heating your home. Your home will be comfortable, and your energy costs will be lower. Add some blinds, and energy efficiency is improved further. 

Because double glazing, Eastleigh customers, is designed to eliminate drafts, this has the added advantage of shutting out unwanted noises. 

Most modern double glazed windows and doors have an array of security features, such as 3-star rated anti-snap locks. These systems make it considerably harder for thieves to force entry, keeping your home, family, and possessions secure. 

Condensation forms in response to the levels of water molecules in the air. As the warm air inside meets the cold air outside, water droplets form. Condensation can be a huge bugbear for homeowners, leading to mould and structural damage. The gas-filled gap between the two panes, watertight sealants, and warm edge space bars help to mitigate this. 

Double glazing won’t eliminate condensation but will reduce it to a more manageable level. Lastly, double glazing can help filter out more of the sun’s harmful UV rays than single glazing, protecting your furniture, possessions, carpets, etc., and most importantly, you and your family.
