Warmcore Windows & Bi-Folding Doors

Warmcore Windows & Bi-Folding Doors

This new window and door system is designed to be as thermally efficient as possible, built around an innovative full width thermal core, with an aluminium outer frame, keeping your heat in your home yet not compromising on strength as the outer profile is made from high grade aluminium.

Strong and secure, Warmcore windows and doors are 25% more thermally efficient than traditional aluminium systems and come with multi-point locking, internal beading and a 10-year guarantee.

Available with a flush sash option that brings the frame perfectly level with the opening part of the window or door.

Our windows can be glazed either externally with enhanced security clips and slimline looks or internally glazed. We offer a range of profile colours; white, light oak and rosewood and the artisan range. However, we can also spray your windows any RAL colour.

From Our Website

We are quite unique in the double glazing industry, we supply and install the best quality products and some of our installers have been fitting for Supreme for 20+ years, with an unblemished trading history since 1986 when it was first formed. There are still a lot of hard sell companies in the industry, no price is given on the initial visit, so you do not have the pressure to sign on the night, you make your decision in your own time. On our first visit we would go though the details of the product you require, take measurements, this very often only takes about 20 to 30 minutes, then we will prepare a detailed quotation at our office, which we can e-mail, post or hand deliver to you.


Supreme Installations was formed in 1986 by Mick Nunney, and has enjoyed over 30 years unblemished trading. When originally formed we were an installation company only, sourcing only the highest quality products for our customers. We have now been continuously trading for many times the guarantee we give, we still strive to maintain and improve our product range and production procedures, so as to offer our customers the very finest double glazing, at a price that suits their budget, but even more important to us, is our commitment to our customers.


When you are looking to invest a substantial amount into enlarging your home with a conservatory, it is firstly worth considering some of the most popular design styles and features. So to make things simple, we have created a guide to the most popular styles of conservatories in England. Victorian conservatories are one of the most popular styles of conservatory in England, and the Victorian style compliments most types of property. Victorian conservatories traditionally have three or five facets to their front elevation plus ornate detailing along the ridge of the apex roof, although the size of detailing can be varied depending on your taste.


Also known in the industry, as vertical sliders, these are elegantly traditional windows, combined with modern practicality, Supreme's sliding sash windows ideally suit many different styles of older property, making them ideal if you wish to maintain your home's period charm. Our PVC-u sliding sash windows combine precision engineering, so not only do our windows slide up and down but both panels inwardly tilt for ease of cleaning and ventilation. Supreme supply and fit a variety of vertical sliding sash window systems to meet many requirements and can be made for you with a whole host of features.


If you have a problem, please give us a call. In many cases we are able to give advice over the telephone, or we will arrange for our service engineer to contact you. You can contact us on 01621 856650 or email info@supreme-installations.co.uk with your information and details of any fault. In the event that the fault represents a security risk to your home your enquiry will receive priority attention. Certass, licensed in 2006, is a not for profit government approved Competent Person Scheme.
