Windows and Doors


Aluminium windows and doors offer strength, durability and are highly resistant to rust and corrosion. They provide slim-lines, more glass area and less visible frame. Aluminium windows and doors are a premium product, maintenance free and built to last, with the life span of aluminium being measured in decades rather than years. Aluminium is very sustainable, endlessly recyclable and very environmentally friendly.

Another benefit of aluminium is the ability for your windows and doors to be coloured any of over 200 different RAL colours. You can even have your windows and doors manufactured to have different colours inside and out. Aluminium Products are painted in a polyester powder coat finish, which is baked on for a tough and resilient paint finish that will not flake or fade over time.

UPVC windows combine style and performance – for every building type.
Obsidian can source UPVC window and door systems to suit any building, from country cottages to apartment buildings and from schools to commercial office blocks. The ranges include contemporary and traditional styles offering exceptional energy efficiency, security and durability, plus easy fabrication and fitting.

A major advantage of UPVC doors is that they are much stronger than traditional wooden doors due to the way in which they are constructed. A major problem with wooden doors in a largely damp climate such as the UK is that of warping. When wood is exposed to damp conditions for long periods it can swell and warp, this is a major disadvantage for doors that you really want to open and close with ease. UPVC doors are rigid and they are weatherproof and dam proof, which means they are not susceptible to the conditions that cause wooden doors to warp. Because UPVC doors maintain their original shape despite the weather conditions, it is rare for them not to fit snugly in their frame and be easy to open and close no matter what the weather is doing.

UPVC doors, like UPVC windows, require very little maintenance. You may need to oil the locking mechanisms from time to time as all locks can become stiff over time. All that is really needed in the way of maintenance is light cleaning of any glazed areas and an occasional wipe down of all other areas as needed. UPVC is an exceedingly durable material, which is one of the reasons for its popularity in the making of windows and doors. Most UPVC installation companies are so confident of the strength and durability of the material that they offer ten year guarantees on their installations.


There are a number of benefits to choosing wooden window frames over other materials such as uPVC or HYPERLINK “” metal. Wooden window frames are:
Attractive – HYPERLINK “” wooden window frames look great in any home and particularly suit older homes and period properties. You can tailor your wooden window frames to suit your home by choosing from a variety of wood types such as oak, mahogany or maple, which each achieve a different look. Wood can also be painted, stained or carved to further customise your window frames.

Environmentally friendly – as a natural material, wooden window frames are automatically more eco-friendly than manmade options such as metal or uPVC, especially if the wood is sustainably sourced, meaning that trees are replanted to replace timber. You can also choose to use reclaimed timber to make your wooden window frames more eco-friendly.

Naturally insulating – wood is a naturally insulating material, which means that wooden window frames help to retain heat within your home, which will in turn lower your household carbon emissions, keep your home warm and reduce your fuel bills.
Long lasting – if properly maintained, HYPERLINK “” wooden window frames can last a lifetime and resist wear and tear well.

Timber is generally available in either softwood or hardwood with some softwoods being harder than hardwoods and vice versa but generally hardwoods are better as they are generally more resistant to rot. As well as a choice of different timbers you also have a range of wood treatments and finishes which help to increase the woods life expectancy. All external joinery supplied by us is treated and then white primed or base stained as standard.
