All our garden buildings have been designed on the basis that any competent DIY customer should have no problem installing a product themselves in a short amount of time. You do not have to be an expert at DIY to build a Dunster House garden building, as we do provide you with comprehensive pictorial instructions. We totally understand that DIY is not for everyone therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you. But before you do, check out our construction video and decide for yourself!

We only use full lengths of engineered precision cut and routed tongue and groove timber in our log cabins. These logs go through a process of being planed, leaving you with a smooth finish. We believe that using full lengths of planed timber gives you a more aesthetically pleasing and stronger product.

Other companies are happy to provide you with rough offcuts, glued and finger jointed together, creating a weakened cabin and off-putting appearance.

We never compromise on quality which is why the insulation that we use in our Warmalog cabins is of the highest specification. It’s called polyisocyanurate and it is one of the best insulators available, it’s so effective that even NASA has used it to insulate the external fuel tanks of their space shuttles!

Polyisocyanurate is a great material because not only is it lightweight and versatile, its high thermal conductivity makes it sought after. Competitors insulation might be cheaper, but they may use Rockwool or polystyrene, which are inferior materials. Polyisocyanurate is said to be 50% more efficient than Polystyrene and up to 100% more efficient that Rockwool.

It’s not just the walls that are insulated in a Warmalog cabin! We also provide the same kind of insulation for the roof (60mm thick) and for the floor (50mm thick). As well as this coverage, the Warmalog cabin comes with double glazing as standard.

All of this heat-retaining technology ensures that any Warmalog cabin can achieve a U-value of 0.69. The U-value assesses the rate of heat loss / gain through all the thicknesses of the combined elements that make up a building component such as a wall, floor or roof. Simply put the higher the U-Value the worse the product performs. Our Warmalogs U-Value of 0.69 is considered to be very low, meaning you’ll save a fortune on heating bills compared to Polystyrene or Rockwool insulated cabins!

Purlins are the large timbers used for structural support in buildings. We use very thick, heavy duty roof purlins to support your garden building.  At 140mm x 45mm they are amongst the thickest purlins available on the UK market. Competitors will often use thinner purlins to keep their costs down which means their roofs will not be as strong as ours. Using thinner purlins risks the roof collapsing or sagging during extreme weather – and that’s the last thing anyone wants!

Unlike our competitors, we only use high-quality spruce timber on our wooden products rather than cheap pine or mixed timber. Why do we use slow grown spruce rather than the much cheaper knotty pine alternatives?

Spruce is considered more stable as it expands and contracts less than pine. This stability means that the spruce timbers in our garden buildings minimise splits from appearing as the timber changes along with the weather.  We responsibly source all our timber, where it grows slowly in the cold northern regions. We all know the old adage of counting the rings to see how old a tree is, well our timber grows slower and takes longer to get to size meaning it has more rings in it. This means it has a tighter grain, and each ring helps prevent cracks and shakes from appearing in the densely packed timber.

Our wooden garden buildings and climbing frames really are built to last therefore we use only the highest quality, slow-grown spruce.  Spruce is much more resilient to warps and splits compared to its cheaper alternative pine. Being a whitewood, it doesn’t discolour anywhere near as much as pine so it is also much more aesthetically pleasing for a garden structure. Considered more stable, less knotty and resinous than pine, spruce will also produce a lot less sap. It is also less dense meaning it is not as susceptible to mould and rot.

Security is important for your garden building, to ensure all your belongings and any valuable equipment is safe. Our uPVC doors feature an industry leading 12-point locking system. Meanwhile, the windows feature multipoint locks with secure key locking handles.

Our 12-point locking consists of four shoot bolts, three mushroom headed espagnolettes, three hook bolts, a locking latch and a 6-pin euro cylinder. The windows feature a multi-point locking system consisting of mushroom-headed espagnolettes which move in opposite directions into metal keeps. Why would you risk your possessions by using less?

So, if you are comparing garden buildings, don’t forget that our uPVC windows and doors offer additional security benefits!

There is nothing more annoying than being in the middle of building something and finding that you don’t have the right fixings to continue. We include all of the screws, nails and fixings that you will need to put your garden building together – not many of our competitors are that thoughtful. This eliminates the need to worry about the type of screws or the length of nails you might need to get started – it’ll all be with your delivery.

All of our garden buildings have pressure-treated floor bearers as standard. This treatment prevents the timber bearers from rotting for up to 10 years and causing your garden building to sink. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do. Who wants to have to annually deconstruct and re-treat the bearers each year!

Due to this costly but effective process, we can offer our customers a genuine 10-year guarantee against rot and insect infestation on the bearers.  We do however recommend applying a good quality water repellent to the timber to prolong the longevity of the timber. Shockingly many of our competitors still offer untreated bearers to keep their costs down, so beware!

All our Pressure Treated timber is for Use Class 3

This log cabin is supplied with domestic standard uPVC window and door frames, just like you would find in a residential property. They come in a colour choice of either White or Anthracite Grey Wood Effect, so you can tie them in with your home, or customise your garden building. We’ve been manufacturing uPVC windows and doors for over 30 years – so we really know our stuff!

The fully glazed French doors provide easy access to your log cabin, make the most of natural light, and can be thrown open to let in plenty of fresh air. They also feature trickle vents to aid ventilation and avoid moisture building up when doors and windows are closed.

To control natural expansion and contraction in the timber, the Warmalog features steel straps on the inside and outside of the cabin known as storm braces, secured by screws and bolts, these braces are adjusted to spread the timber’s natural movement equally across a much larger area, thus avoiding the worst effects of localised expansion and contraction within the wood.

Our cabin logs are designed to interlock with a chamfered finish to ensure a snug fit. The chamfered notch system is designed to prevent damp or wind penetration. Our interlocking logs make for speedy installation and minimal need for tools. Our garden buildings have been designed on the basis that any competent DIY customer will have no problem installing a product themselves in a short amount of time.

Unlike some competitors, we provide interlocking precision-engineered chamfered logs. Keeping your log cabin watertight and free from unsightly draft-producing gaps.

OURS:

THEIRS:

Add a flyscreen to the windows of your garden building, so you can benefit from letting the fresh air in while keeping those pesky insects out, without restricting visibility. An insect screen will allow you to still view out of the window to survey your surroundings, watch nature and look out at the beauty of your garden.

As the effects of global warming take place, the Earth is changing, with reports suggesting an expected increase in the number of insects around the world. An increase in temperatures over the coming years will speed up the growth rate of some insects. This includes the domestic housefly, which could see a rapid rise in its population. Order your flyscreens now to protect you for the future.

Keeps out insects

It’s always nice to be able to throw open the windows of your garden room to enjoy a warm summer breeze or cooling air. With the addition of a flyscreen mesh, you can enjoy the warm weather without worrying about unwanted insects getting in. Keep those flying insects from buzzing around as you try to work in your garden office or relax in your summer house.

Ventilation and comfort

Ventilation and circulation of fresh air is also important for the wellbeing of you and your garden building and helps to maintain a relaxed and comfortable environment inside. Flyscreens for windows give effective protection so you don’t have the annoyance of flies and other creepy crawlies.

Durable materials

The fly mesh is made of strong and water-resistant materials to last. Easy to fit

It is provided as a simple ready to install screen to fit the size of your garden room or log cabin window and fixes to the window frame. Easy to follow instructions will be provided alongside your order.

Easy to use

The roller flyscreen is easy to operate, with a handle to pull it down when the window is open, and a small clip will keep the screen in place. When not in use, the retractable flyscreen design allows it to be discreetly hidden away.

The bearers of your garden building are pressure treated to help protect your garden building from the ground up. We provide a 10 year guarantee against rot and insect infestation for all pressure treated timbers.

Unlike some competition, we can offer a genuine 10-year guarantee against wood-eating fungal and insect infestation on pressure-treated timber.

All our Pressure Treated timber is for Use Class 3

Our garden rooms are supplied with domestic standard uPVC windows and door frames available in White as standard or Anthracite Grey Wood Effect. So you can either tie in with your home frame colours or customise your office or garden room!

Not all double glazing is the same, and what truly makes our double glazing stand out among the rest is the sealed unit. We supply a 28mm, double glazed sealed unit. These units comprise of 2 panes of 4mm toughened glass on either side of a 20mm aluminium spacer bar, designed to absorb any moisture within the sealed unit, which could lead to condensation inside the glazing. These sealed units comply to BS EN 1279 standards. This EN standard covers the requirements for insulating glass units, including thermal and sound insulation. The sealed units are independently tested to show that they will not suffer from any form of condensation within the unit.
