Pressure treated floor bearers
Our 70mm thick floor bearers are pressure treated. This forces the treatment deep into the timber using a large pressure treatment tank. This treatment protects the timber during years against rot and insect infestation on these parts.
Slow grown spruce
We use slow grown spruce for the walls of all our Garages as it is better all round than pine. Spruce is less porous than Pine and so less likely to shrink, warp or split. We only select slowly grown timber from colder climates which also helps keep the timber more stable as the rings are densely packed. It is also a less resinous timber than Pine, which makes the possibilities of sap ruining clothes or furnishings much less likely.
4mm toughened glass
We use 4mm toughened glass in our windows and doors for increased safety and security. It's much better than 3mm horticultural glass, commonly found in garden buildings, as it's a lot harder to break, and if ever it is broken it breaks into small pieces rather than large shards. It is also much harder to scratch than the plastic alternatives, styrene, acrylic and perspex, so will preserve the clear view out for far longer.
Tall walkthrough height
With our extra tall doors it is possible to walk right the way through without any danger of bumping your head. Unless you are over 1.86m.
Avoid sagging roof
Our heavy duty 140mm or 210mm high by 45mm wide supporting roof beams prevent unsightly sagging.
Adjustable Storm Braces
Our adjustable storm braces tie the garage roof to the rest of the building so it withstands stronger winds. Unlike others on the market they are adjustable to allow for the natural movement of the garage, which helps prevent gaps appearing between wall logs as the logs settle and move.
24mm Double Glazing
The double glazing on these garages is 24mm thick. We make these sealed units ourselves to European Standard EN1279. It is an excellent way of insulating your cabin and extending its usage from a seasonal building to one that can be used throughout the year.
3 Gate Hinges
Gate style hinges create a more authentic and traditional finish to the garage.
Plastic Vents
We have included ventilation as part of our garage kit to help prevent condensation build up within the building. We use two pairs of plastic base plates, one round and one square. The external round vents have chamfers to help direct water away from the hole, the inner square vents have an integral fly screen to prevent insects from entering through the vent. The pair of vents allows a flow of air through your garage to help keep out musty smells.
No Glued together Offcuts
We only use full lengths of timber in our garden buildings - we don't glue separate offcut pieces together with finger joints. Not only are they stronger, but they look much better too.
4-Point Locking System
Our exceptional doors feature an industry leading four point locking system. It features a hook, locking latch and two roller locks. We use a type of lock that has 6 pins and has been tested to BSEN 1303:2005 classification to ensure it is a safer, more secure locking system. Our windows have multipoint locking as well, using the same type of system as we supply with our uPVC windows and doors.
