Unlike many double glazing companies who do a "little bit of everything" that is all that we supply and install.

Whether the problem you currently face is heat loss, draughts or too much noise from your existing windows it is the best solution to make your home more comfortable and reduce your heating costs.

Our expert aluminium secondary glazing installers will ensure that their many years of experience are used to fit the units effectively, correctly, quickly and with minimal disruption. There is normally no need to do any internal redecoration after you have had your windows fitted.

Whether you are considering secondary double glazing windows for thermal insulation or for noise reduction you can be reassured that our quality products have been fitted in hundred's of properties throughout the UK.

Why do so many people trust us to meet their internal double glazing needs?  Because it gives great noise insulation, reduces heat loss helps to reduce condensation and improves security.

With no disruptive building work needed and no redecoration it is the ideal product for retaining the character of your property.

We offer a comprehensive range of well-designed and reasonably priced windows which are cleverly designed for ease of fitting and come pre-assembled. As standard they include an aluminium frame combined with an integral timber frame to make it easy to fit to your existing window frame whatever the circumstances.

Where noise is a major irritant, by creating the correct gap between the primary window and the secondary glazing we can achieve massive reductions in noise transmission and it is the best product to use if you are bothered by outside noise.

Black Knight products are ideally suited to most types of property but is particularly useful for listed buildings and those in conservation areas where the replacement of the primary window is often not allowed at all, or brings huge cost to comply with the official requirements.

Planning Officers will often insist on full replication of existing windows with the costs being prohibitively expensive.

However, the best residential secondary glazing systems are not just a suitable alternative – in most cases they will surpass the performance of primary windows both for heat loss reduction and noise reduction. 

Don’t go to the expense and inconvenience of having your existing windows replaced unnecessarily – opt for the cheaper, easier to install & more environmentally friendly alternative.

We will always advise you fairly and answer any questions you may have honestly and without any pressure. If you need advice or a quotation please call free on 0808 168 5208 or send an e-mail and we will contact you to discuss your requirements.
