PREMIUM GLASS UPGRADES

Estimates Suggest That

Up to 26% of all the heat lost in the home escapes through the windows.

Modern energy efficient windows help to reduce this heat loss.   As well as capturing the heat from outside, they also lower the heat needed to heat the home.

Energy Efficient Glass

Works in two ways to lower the heating required to maintain your home to your desired temperature.

Firstly, it allows more warmth from the sun (“free energy”) and natural daylight to pass through the glass. Secondly, it retains more heat within the room.

The Achievable Energy

Savings from each home will depend on a number of factors, but can be upto 22% on your heating bills.

Planitherm Total+ is Europe’s best selling high performance low-emissivity glass (Low E), incorporating the very latest advancements in thermally insulating coating technology.

Planitherm is the UK’s leading Low-E glass of choice when it comes to achieving the best possible Window Energy Ratings.

With its transparent, invisible metallic coating, Planitherm captures free energy from natural daylight, allowing it to pass through the glass and warm the home.

At the same time, the coating reflects the heat generated in the home back into the room, rather than allowing it to escape through the glass, further contributing to the energy efficiency of the home.

Planitherm offers many traditional features, which set it apart from traditional Low-E products.

Over the years, glass technology has changed greatly, so old glass units may now have a range of glazing problems.

These include –

  • Old inefficient glass units
  • Misted and blown units
  • Draughty and insecure frames
  • Worn gaskets
  • Broken and non-lockable handles

At Lancashire Glass Replacement, we fully refurbish and upgrade your existing windows. Most large window companies are only interested in completely replacing your windows. This is because they have made large investments in frame manufacturing plants.

You do NOT need to replace your frames if they are in good condition. You could save £'s by contacting Us Today!

Our glass sealed units are made up of two special types of glass; the inner pane is Planitherm Low-e glass. (The UK’s bestselling low emissive glass) which stops heat escaping, and the outer pane of Planitherm Low Iron glass, a special “extra clear” glass which allows more solar heat in through the windows.

The sealed units are bonded together with a Warm Edge Spacer bar in between the two panes of glass.

When it’s cold outside and warm inside, heat escapes through the traditional aluminium spacer bars, leaving the inside edge of the window colder than the rest of it. This heat loss means more heat is needed to maintain a comfortable indoor temperature.

The energy efficiency of a sealed unit can be further increased by substituting dehydrated air with an inert gas, such as argon. The introduction of Argon into the cavity of a double glazed unit reduces the heat transfer between the panes, helping to keep more heat in during the winter, and out in the summer. This phenomenon results in a 34% lower thermal conductivity than air.

Our PREMIUM ‘A’ Rated glass unit upgrade consists of

  • Low E glass upgrade.
  • Low Iron glass upgrade.
  • Argon gas filled units.
  • Spacer bar upgrade.
  • Frame reseal as required
  • Clean UPVC frame.
  • Gasket upgrade as required.

With ever increasing energy bills,  it’s important to ensure your home is as energy efficient as possible. By upgrading your sealed glass units to Planitherm glass, you can significantly reduce the cost of heating  your home.

How Low E Glass Coating Works

PROMOTIONAL VIDEOS

Performance Data

Heat Transmission

The amount of the sun’s radiant heat, which is allowed to pass through the glass. A higher number will contribute to greater energy efficiency.

Light Transmission

The amount of the daylight that is allowed through by the glass. A higher number indicates a greater degree of daylight comfort.

UV Reduction

The amount of the sun’s UV rays which are blocked by the glass. The higher the number, the greater the UV protection.

U-Value

A measure of internal heat loss for the window. The lower the number, the greater the insulation.

Indicative WERs

The typical Window Energy Rating that could be achieved with each Glazing Option. Note that the actual WER will be affected by the other window components such as frame, spacer bar and gas filling – your PLANITHERM Network Installer will be able to advise you on this.
