Secondary glazing installations across North Wales, Cheshire & Merseyside

A period home with secondary glazing

You are probably reading this page because you are pondering what options to take to lower your energy costs, retain warmth to your home and Reduce noise pollution through your period windows, these are usually sliding sash windows or casement windows, often fitted to properties that are listed building or are in conservation areas.

You have several options at hand if you are not in a listed building or conservation area, you could double glaze the windows with our slim double glazing system this will give you double glazing in your original period windows without altering the look of the windows as they are virtually indistinguishable from single glazing and give you the thermal performance of a new window, just click on the double glazing button above for more information.

For those of you that live in grade II listed buildings or conservation areas your options start to get a bit more restrictive due to government regulations and local authority guidelines that require you to keep the historic time line of your period property in tact as much as practically possible.

So this is where secondary glazing will come in to its own, it can be retro fitted to the inside your windows with minimal disruption to the internal fabric of you period home and can be fitted in a quick ant timely manner, the typical fitting of secondary glazing in the average sized home is around 1-2 days.

There are many layouts and styles of secondary glazing to suit your individual needs, they are individually made to fit the sight lines and profiles of your period sliding sash windows or casement windows, with ultra-thin aluminum profiles to let in as much natural daylight as possible.

All our secondary glazing is available in three standard colour choices of White, anodised Aluminum or Brown, but all frames can be sprayed in any RAL colour for an extra cost.

This is just a brief description of our secondary glazing systems and what we can provide for a detailed analysis of our products please go to our sister company at the link below.
