>>>>>>>01327 263085<<<<<<<

NEW for Post Pandemic -  discounts for purchases of three or more frames.

Insulating windows for Listed, Period, Historic or contemporary buildings where plastic is unwelcome!     

The price lists, later, relate to the "one off" costs for supply only windows.
WE SUPPLY ONLY using the style illustrated here. WE FIT  - more products and solutions are available when fitting  - delivery currently up to 20 working days; still adjusting for CV-19!   
FITTING APPOINTMENTS are currently being made for 6/8 weeks ahead due to work volume and backlog.

D.I.Y.  fitting is so easy with these fully assembled, ready to screw in place; secondary window frames!  Your Handy-PERSON can do it! If you can do IKEA furniture, you can do this!

Noise Reduction:

Using thicker glass than that in your primary windows improves noise reduction by a huge amount by reason of differing resonant frequencies. In some situations, we use Stadip laminated Noise Reduction glass; due to it's high cost, not everyone can budget for it - although it is becoming increasingly popular on NEW ESTATES where the houses are often bordered by main roads and by-passes...


The price lists in the later pages can be used as a top end BUDGET only. We use this as a basis for costing single windows, delivered to Mainland U.K.  Multiple units are, of course, subject to HUGE savings, as are fitting contracts. 

GET IN EARLY for Winter ...  

around the corner????

Reduced prices on ALL new project orders placed in June & July ... a minimum of 10% saving guaranteed.

START SAVING ENERGY and reducing your fuel bills by using Pilkington "K" glass in your new secondary windows.

Secondary Double Glazing will reduce bills NOW and reduce the price rise impact over the next 5 years and into the future......

About Us

Secondary Double Glazing operates in a wide radius of our base near Banbury. We were created from a glass merchant, which I managed in London, S.W.3. CHELSEA GLASS, previously Chelsea Glassworks Ltd.  1976 saw us establish in our own right. We expanded across the South, covering, Sussex, Hampshire, Kent, Surrey and parts of South London.

After the Central London area became unrealistic in cost and service terms during in the 1990's the business grew from its new home... near Amberley, West Sussex. I decided to close the business there in 2006 having provided solutions to 1000's of properties.

NOW, since 2008, the business has grown again based on the Warwickshire & Oxfordshire  borders. We cover a wide radius; taking in Birmingham, Oxford, Leamington Spa, Warwick, Stratford on Avon, Berkshire and further afield on larger projects. We have a presence of great significance at Derby and Yorks, working in Wales, Borders and  other parts of the Kingdom. Our installation crews are now a stand alone business. Your enquiries for supply and fit will be responded to by Graeme or David.


Period, Listed and Conservation homes and commercial properties find it difficult to enhance heat retention and reduce noise ingress. We have the answers!

Poor quality "builders" pvcU products are often resourced from the lowest end of the marketplace - hence, sadly, we provide answers to NEW BUILD properties too.

In the first instance, CONTACT US and we'll send you drawings and details of the multitude of options via e-mail. 

We have no salespeople so no need to worry about the things that concern so many ... having a "closer" sitting in the living room all night!!!


We supply and fit ....
