Double Glazing: Your Range Of Options When You Choose Seemore Glass

uPVC Double Glazing

Flush Sash Windows

Our flush sash windows are ideal for period or listed properties or homes located in conservation areas. It’s even possible to request a heritage specification when talking to a member of our team about your design requirements. Our thermally efficient double glazing can comfortably achieve a U-value of 1.3 to make your home in Brentwood warmer.

Sliding Sash Windows

Our heritage sliding sash windows are characterised by slimline designs. But there is more to our sliding sash double glazing than stunning aesthetics. Depending on the specification you choose, a U-value of 1.0 could be yours to enjoy. Internal beading and a multipoint locking system will be used to prevent forced entry into your home in Brentwood.

Our sash windows form part of a wide spanning collection that includes different styles, so you’ll be able to choose a product that’s right for your double glazing project in Brentwood. Choose from our heritage range to enjoy a sash window that can tilt inwards and includes ovolo beading to provide incredible year-round protection for your property.

If you prefer something a little bit different, we can install mock heritage sash windows that perfectly reproduce the look of timber. This look is achieved through the introduction of mechanical joints that are created without the need for welding.

Aluminium Windows

Our aluminium double glazing is hardwearing. It isn’t susceptible to rusting, rotting, warping or any other form of deterioration. Your installation will also achieve finer sightlines than those produced by an equivalent window made from uPVC. Your home in Brentwood will also be quieter, thanks to the acoustic-cancelling technology included.
