Bevelled

Ovolo

Lipped Casement Windows simply have sashes that open out on special hinges that use friction to keep them open in the position you chose. Because this type of window opens out and has a rebated sash which lips over the outer-frame they offer superb protection against the wind and rain. They can be used to replicate any popular style of timber window with sashes that can open from the side or the bottom

Lipped Tilt & Turn Windows are most popular across mainland Europe allowing the biggest possible glass area. They are characterised by the fact that they open into your house. This can be useful if you have limited clearance outside and they are very easy to keep clean as even the outside of the glass can be washed easily from inside the room. Using a very clever hinge and locking arrangement you can either open the top of the sash at a ﬁxed angle to allow gentle ventilation or you can open it from the side giving the maximum possible aperture to let in as much fresh air and light as possible. Be careful to consider your available space inside, as a big tilt & turn window can take up quite a bit of space in a small room

We will help you design the style best suited to your property, this could be simply copying the existing window on maybe something a little different. There is a separate information sheet available showing the most popular configurations if you want to see what else is available

Advanced Technology

With the rapid advancement in PVC-u technology, you would often now be hard-pressed to tell the difference between PVC-u products and their timber equivalents. This provides you with a multitude of finish options. You may find for example that choosing a realistic Woodgrains like Rosewood or one of our Oaks woodgrain the finish will help to blend more sympathetically with your home and garden. Colours such as Black, Grey, and Cream are also increasingly being used to great effect as well as an array of bespoke coloured woodgrain colours. And remember, unlike their timber equivalents, they will not need painting, and they will be guaranteed for years to come

What is more, we can Kolorbond your windows in virtually any colour combination for the hundreds of available RAL colours - including dual colour, in smooth and textured

All styles come with your choice of Clear, Obscure, Satin, Leaded, Georgian or decorative glass with Stains and Bevel

We design your windows on our laptops and tablets in-store or in your home, so you can see exactly the style and finish, as you are making your choices - you also get to see how design and colour choices affect price

Window Energy Ratings

As part of the Governments overall initiative to reduce the levels of carbon dioxide emissions, they have put controls in place to reduce the energy lost from domestic dwellings

Window heat loss can account for up to 30% of the total heat loss from your home. Therefore replacement windows are now energy rated which will help to reduce harmful CO2 emissions and help cut the cost of heating bills. Ultimate window profiles along with the glass sealed unit specification are fed into a computerised simulation test to measure

Based on the results, windows are then rated from A-G with A-Rating being the most thermally efficient

Thermal losses from convection, conduction and radiation

Warm air leaks out through the window

Why choose Ultimate?

In order to meet the governments thermal performance targets and current Building Regulations, all replacement PVC-u windows are to achieve a U-value not exceeding 1.6 (W/m2.K), therefore certified to Energy Ratings "C" or better

All Heronhurst Ultimate Collection Windows are certified A for our domestic customers

Made to measure

All Ultimate window and door profiles are produced 70mm in depth, often the same depth as conventional wooden windows

Because of this, Ultimate frames are more likely to provide a direct replacement for the windows that have been removed and will refit up against existing plaster lines for a neater finish

Advanced compression

Internal and external gaskets are fused to all sections which will prevent the seals shrinking over time

A 9mm ‘flipper’ seal compresses against the glass sealed unit to ensure ultimate weather protection. The seal remains in-line with the profiles to enhance the finished appearance

Chambered Profile

The PVC-u profiles have internal chambers that will not only help improve thermal performance but can also include metal reinforcing as and when specified to add rigidity and strength to the frame

Built to last

Manufactured from 3mm Grade-A PVC-u, Ultimate profiles guarantee a consistent, superb surface finish. An internally sloped surface directs any water penetration away from the window via a built-in drainage route

Ali-lock Georgian Bar

You may decide to have decorative Georgian Bars applied to your windows

The unique Ali-lock Georgian Bar includes scribed PVC-u clip-on bars connected to full length aluminium fixing strips. This innovative system ensures the Georgian grille does not shrink, warp or detach, regardless of weather conditions

Smart Safety Solutions

For your safety, easy clean/fire escape hinges are fitted as standard to all side-opening windows. These will open to a full 90 degrees to give you an alternative means of fire escape (dependent on window size) and can slide towards the centre to allow easy external cleaning

Turn the slot-bolts located on the top and bottom hinges 90o and simply slide the window across for easy external cleaning

The window will automatically realign upon closing. The unique dual purpose key can be used to lock your window handle and to operate the hinge slot-bolts as shown right

Safety, industry-leading security, and quality built-in as standard, giving you complete peace of mind

Our windows make more of ambient heat

In winter, the energy efficient coated glass used in our windows retains warmth within the home. It’s also designed to exploit radiant heat energy from the sun. These properties result in significant fuel savings compared to a single glazed dwelling.

Above: The images show just how effective fitting energy efficient windows to your property can be. The right-hand side of the property still has the original windows – the reds and pinks show heat escaping. However, the new extension on the left is fitted with energy efficient windows, the lack of reds and pinks proving they help dramatically reduce heat loss

Energy Saving Windows and Doors - A Better Choice for Your Home

Modern double glazing doesn’t just look good. It can save you money too. From styling to performance to saving energy, our advanced glazing technologies are engineered to give you a comfortable, secure, quiet, energy efficient home

Reduce wasted energy and cut bills

Choosing energy efficient windows, doors and conservatories to replace single glazed or older double glazed units saves energy from day one. In fact, replacing the windows alone could reduce your heating costs by up to 20% - perhaps worth up to £321 a year*

Choose better looking frames

Clear, uncluttered sightlines ensure windows look well proportioned, elegant and attractive. Features like our low sightline weatherseal ensure performance and style with savings

Reduce condensation and noise

Lowering heat loss at glass edges can cut window, external door and conservatory condensation by up to 80%. Glass units and our high performance gasket helps reduce noise pollution over a wider temperature range, too

Handle styles

We offer a range of handles from modern through to traditional - even hand forged handles, in 8 finishes so you can individualise your windows to your home

Means of Escape

When replacing any window, the opening should be sized to provide at least the same potential for escape as the window it replaces. If the original window that is being replaced was larger than necessary for the purpose of escape, then the new window opening could be reduced to the minimum as specified in the criteria below

The means of escape should be considered for any new window installed to an extension or existing dwelling. If an escape window is required, then criteria set out below should be followed. It is also generally good practice to replace any window on the first floor that is not used as an escape window with an escape window

See below for the general criteria for egress windows:

Width and Height - Either of these are not to be any less than 450mm
Clear Openable Area - No less than 0.33m²
Cill height - The bottom of the openable area should be no more than 1100mm above the floor area

Only one window per room is required

Ventilation

Windows and doors provide ventilation to rooms within a dwelling and rules apply to how much ventilation. The type and extent of ventilation will be dependent on the use and size of the room. For example, rooms where steam will be produced (kitchens, bathrooms, utility rooms etc) should be provided with higher levels of ventilation (normally mechanical fans and windows) than other rooms where suitably sized window openings and background ("trickle") ventilators may suffice

Safety glazing

Safety glazing should be provided to any glass in a critical area. Below is a list giving general view as to when safety glazing is required:

Unobstructed openable area: At least 0.33 square metres and at least 450mm high and 450mm wide
Within any glazed door up to 1500mm from floor level

Unless otherwise stated, all glazing provided by Heronhurst is Safety Glazing (Toughened) as standard regardless of its location, for your peace of mind
