Sash Vs Casement Windows

Emre Gurler • May 14, 2022

When it comes to period and listed properties, there are two main types of windows; Sash and casement. But what is the difference between a sash window and a casement window.


Sash windows


One of the biggest advantages of sash windows over casement windows is that because the windows slide up and down rather than opening outwards, they are more protected from the weather and tend to last longer. Sash windows became popular in the Georgian era and remained popular until the Edwardian era. 


Sash windows tend to be far more suited to a traditional home design and can add a distinctive and elegant feel to any home.


Their flat designs are often more practical when next to space restricted areas in gardens and patios. Hanging internal blinds and shutters with casement ironmongery can often be a challenge, but with Sash windows this becomes a far easier task, with an end result of more ventilation with no compromises on privacy


Casement windows


Casement windows are hinged windows, usually side hung. They started to gain popularity in the Edwardian era, and became the window of choice in the 1920s and 1930s onwards. 


Some of the very oldest windows still surviving today are casement windows. In Tudor times when glazed windows first started to emerge, casement style windows were made by fusing together a series of small panes of glass with lead. 


Due to their sleek and unobtrusive look it has made them very popular in modern design. Casement windows are often more energy efficient than Sash windows because it fits tightly against the frame when closed


Casement windows can also be easier to open, however well maintained Sash windows are too.

Why We Prefer Sapele Timber Over Anything Else

By Emre Gurler • 14 May, 2022
Why We Prefer Sapele Timber Over Anything Else Not all timbers are created equal, different types of wood have different features and profiles that will work best in different contexts and different projects. Sapele is a robust West African Hardwood timber that is reddish-brown in colour and does not have any natural defects like knots and split such as other timbers, in particular softwood. If you are in the market for a strong hardwood that offers durability and weather resistance for your clients, then Sapele could be the right option for you. In this month’s blog post, we explain why we prefer Sapele over other types of wood and why you should choose it too if you want the absolute best in quality & reliability. Replace your windows Around 10% of heat loss occurs through your windows. So if you’re serious about saving on energy bills and driving down heating costs, your windows are a great place to start. Many assume that just because they have double glazing that their windows are energy-efficient. But this isn’t necessarily the case. Not all double glazed windows are created equal, and the [British Fenestration Rating Council](https://www.bfrc.org/) has a scale of energy efficiency ranging from A++ to E. And don’t make the mistake of assuming that replacing your windows means compromising on their style or character. We provide bespoke windows made from the highest quality glass as well as Sapele hardwood, coated with Sikkens microporous paint. So you can get improved durability and energy efficiency without compromising on appearance. 1. Extremely Durable Sapele is a very strong, stable and durable tropical hardwood that is very well suited to joinery manufacture. The timber is sourced from West Africa and Cameroon and is classified as moderately durable with a Class 3 to 4 durability rating. It can be used for both indoor and outdoor applications. With Sapele there is no requirement for preservation treatment as the wood lacks permeability which makes it resistant to treatment, this does also make it particularly suitable for heritage properties. Another durability point to consider is the fact that Sapele is highly rot and weather resistant which in turn makes the wood an ideal choice for external joinery applications such as windows and doors. Durable hardwoods such as Sapele have become virtually synonymous with properties in conservation areas.

What is the difference between hardwood and softwood?

What is the difference between hardwood and softwood? In general, hardwood comes from a deciduous tree which loses its leaves annually and softwood comes from a conifer, which usually remains evergreen. Hardwoods tend to be more dense The denser a wood is, the harder, stronger, and more durable it is. Most hardwoods have a higher density than softwoods. When it comes to doors and windows, hardwoods are far more common, and with good reason. Softwood however is less expensive than Hardwood. Whilst Hardwood is typically more expensive, this has to be factored against the longevity of Hardwood making it potentially more cost effective in the long run with reduced maintenance costs and increased lifespan. Sapele is a very strong, stable and durable tropical hardwood that is very well suited to joinery manufacture. The timber is sourced from West Africa and the Cameroon and is classified as moderately durable with a Class 3 to 4 durability rating. It is very attractive, thanks to its dark reddish brown appearance. With Sapele there is no requirement for preservation treatment as the wood lacks permeability which makes it resistant to treatment, this does also make it particularly suitable for heritage properties. Although all wood is extremely susceptible to fire, hardwoods are naturally more fire resistant than softwoods. This makes it perfect for properties that may have had a history of fire-damage, or that are particularly vulnerable to fire damage. And whilst hardwoods are, in fact, hard, softwoods are not really soft; they're simply more susceptible to dents and knocks. Impervious to such incidental damage, durable hardwoods such as Sapele have become virtually synonymous with properties in conservation areas.

Increasing the Sell-ability of Your Home

By Emre Gurler • 18 Nov, 2021
As well as many other benefits like energy savings, soundproofing and reduced condensation, having replacement windows and doors can significantly increase the sellability of your home. Research suggests that on period properties in particular, sash and wooden windows when sympathetically and professionally installed can in fact increase the value. Whilst timber windows are traditionally more expensive than UPVC it’s all relative, in that the increased outlay is more than matched on the value added to your home, easing any potential sale and increasing the asking price. When replacing windows particularly with listed properties they should be replaced like for like, should this not be the case it can act as having a negative effect on the value of your home. Estate agents insist that new double glazed windows will add value and make your home more sellable. One Sussex agent (Henry Adams) stated that they had sold an edwardian terrace cottage for 40,000 more than predicted basis the owners had replaced single glazed windows with wooden framed double glazed windows costing 18,000. So in conclusion, it makes sense to consider all the options and not discount the possibility of opting for timber windows, as otherwise you may just end up having to discount the price of your home!

WOOD vs UPVC

By Emre Gurler • 18 Nov, 2021
Today’s timber frames continue to be developed and innovated, all to offer homeowners the best performance as well as functionality. That’s why we make no bones about the benefits of hardwood double glazed windows. To help highlight this we thought it would be best to dispel some of the myths about them. You might find yourself surprised by what the facts show MYTH: If looking for double glazing, you need UPVC windows. Far from the truth; hardwood windows are in fact able to be double, even triple glazed, and we are one of the few companies that can offer this service. At Landmark Windows we can replace both single glazed Sashes with Double glazed units. Alternatively there is slimlite double glazing, giving all the energy saving benefits, whilst maintaining the character and feel of the windows. Slimlite double-glazing windows are constructed with a clear outer self cleaning pane. The emissivity coating is on the inside face into the cavity and reflects the heat back into the room. The warm edge technology ensures maximum energy conservation. MYTH: Wood rots quickly and is not cost effective, whereas UPVC will stand the test of time and does not discolour. A big misconception in the public is how UPVC lasts longer as it will not rot. But, it’s the other way around, plastic will degrade overtime whilst most hardwood windows have an estimated service life of around 60 years, that’s twice the life of UPVC windows. Plastic windows can become discoloured and brittle as a result of exposure to the sun, unlike wooden framed windows, which can be repaired, plastic can not and will have to be replaced. At Landmark Windows we only use the best Sapele hardwood, to enable us to offer our clients long lasting guarantees on all our work, giving you a lasting peace of mind. MYTH: Wood windows are too expensive Although wooden framed windows may be slightly more expensive initially, in the long run they are often much more cost effective during their lifespan. This is due to the ability of being easily maintained and re-painted, whilst UPVC windows would ultimately need to be replaced. MYTH: UPVC adds value to your property Research shows that carefully manufactured and installed sash windows can have an immense impact on the sellability of your property. Often house buyers will take into account the cost of replacement when valuing a property or making an offer. DID YOU KNOW; If you have a period home or a home in a conservation area, UPVC windows could even devalue your house by as much as £20,000! Unsympathetic replacement of windows and doors-with a large percentage being UPVC- represents one of the biggest threats to property values. Research has also proven that whilst UPVC windows can decrease the sellability of your home, it can also dissuade prospective buyers from making an offer. MYTH: Timber windows are a poor insulator Here’s a myth that continues to bemuse. While it’s true that aluminium and UPVC window frames have thermal breaks and internal multi-chambers for better insulation, wooden windows insulate naturally and don’t require such an extra level of design. Put simply, timber doesn’t just evoke a sense of warmth, but literally helps keep you warm. Especially, if double glazed. Is it time to replace your windows? Or are you just looking into options for the future? Whatever it may be, we are here to help you!
