Underfloor Heating and Screed

Underfloor Heating and Screed

This is a view of a section of Celotex insulation sheets, they are aprox  100mm thick , on top of this a layer of black plastic sheeting is applied before the underfloor heating pipes are applied.

This section shows the underfloor heating pipe applied to the surface, the pipes are secured by plastic staples. You can see that there is approximately  200mm of space between each pipe. 

This view shows all the zonal pipes coming back to the manifold.

This image shows the manifold , all the zonal pipes meet at this junction, the manifold is then connected the the air source heat pump and the expansion vessels.

Another view showing the under floor pipe layout.

This shot shows the metal leveling instruments positioned with the aid of an infra red surveyors level. The screed will be poured until it meets the underside of the adjustable screw of each tripod. this will enable the screed to be poured and an even level will be achieved throughout the ground floor area.

This shot shows the ducting for the IT and electrics for the main open plan office.

The Screed arrives. Lorries arrive within 10 mins of each other from a depot outside Dorchester.

The Screed is poured in to a trough which has a pump attached on the underside, any over sized particles can be removed by using a mesh above the trough.

The Screed is poured, more is required in this zone  !

The main ground floor office being filled.

Screed is directed through a large hose pipe so all areas are covered and a large leveler is used to make sure

the screed is evenly spread.

This shot shows the screed set the next day. A white colour as this jagged edged sand comes from a sand quarry in Dorset, as opposed to a pink colour that you will find with screed processed from Devon quarries, notably Rockbeare.

A shot showing the floor in the gallery. The Screed will be sanded in 2 weeks time to remove any uneven areas and to provide a finish for the final floor application, in this case engineered wood flooring 14 mm .

Floors and Wind braces.

Floors and Wind braces.

This shot shows all the first floor joists in place.

This shot was taken from the exterior scaffolding.

The floor panels went in over 4 days, giving you an idea of the height and space created on the first floor.

The western gable end is not supported with a floor, therefore we have had to install wind bracing which firms up the wall. this photo shows one of 6 wind braces which we need to install. they are anchored into place using the ground floor block and beam construction.

This shot shows the anchor brace.

A View showing the Wind brace terminating at the eaves level.

Installation of exterior wall panels.

Installation of exterior wall panels.

The exterior wall panels came in approximately 44 sections, they were manufactured in south wales and delivered to us by articulated lorry.We had to unload the articulated lorry from a near by lay by using a tractor and trailer kindly lent to us by Wilfred Tratt our neighbour. The panels went up very quickly, they were all up within a week. Small adjustments had to be made.

This view is looking West to the gallery at the end.

The wooden panels are lined with a vapour blanket which deals with any condensation

that might arise.

This view is taken from the South West showing all the panels in situ and highlighting the layout of the windows.

The cladding is attached to battens. The cladding is pressure treated Douglas Fir, the panels are approximately 12 inches wide. This is a view looking towards the air source heat pump shed.

Another view taken from the South west but showing the basement to the far left of the building.

Installing the Roof and Liner, insulation and the exterior cladding .

Installing the Roof and Liner, insulation and the exterior cladding .

The first job was to put up the inner liner, this is a steel corrugated sheet painted white which will form the inner side of the roof. This went up over 2 days on the main curved section of the roof. The Lean to roof was a composite sandwich of liner insulation and exterior corrugated roof, which you can see has already been installed in this photo.

This is a view of the white liner from the ground floor. The galvanized purl-ins will be etched in acid and painted white to match the main white beams.

Another shot of the liner and part of the first floor showing the joists.

A view taken in the gallery atrium giving you a sense of the scale of the atrium space.

A view of the underside of the composite roofing for the lean to.

A View of the lean to roof with part of the liner and metal tracks of the curved roof.

This shot shows the 12 inch thick insulation wool being laid in the channels before the exterior roof is applied.

This shot shows a metal roof cladding, we have tried to keep as close as possible to the original black bitumen corrugated roofing of the old Dutch barn.

This shot shows as profile of the exterior roof sheet and the gutter boards installed ready for the guttering.

A View showing the completed lean to roof and curved roof.

Timber Frame Walls to be erected and final roofing installed.

Scaffolding is erected on the south side to help the roofers install the curved roof. The curved roof comes in 3 parts. The metal liner is installed first, followed by metal spacers and insulation finally the exterior curved sheet is installed to complete the roofing.

This shot shows the timber framed wall panels which will be installed to form the basis of the new walls. The Timber framed walls were manufactured by JSI Timber frames by Nathen's team in Milford Haven and designed by Andy best from www.studs.org.uk in Trowbridge.  This 12 wheel articulated lorry delivered to a large Lay-by just north of Monkton, 1 mile from Woodhayes. We loaded the timber frames on to a tractor and trailer so that we could transport to Woodhayes. The Articulated Lorry would not have reached the site due to the narrow East Devon Lanes.

This shot shows the 6 x 2 inch capping plates which will be installed above the steel I beams to take the lower end of the curved roof and tie in the new timber framed walls. Bellow the 6 x 2 timber is half of the Douglas Fir cladding which will be applied to the exterior of the building.

This is a shot of the curved roof components including the insulation which will be sandwiched between the lower steel liner and the exterior steel curved roof.

"Battlesden Copse", a new Broad Leaf Copse for Woodhayes Farm

This track was created late last year to enable access to Crown All Wood. This will enable timber wagons to move timber from the ancient woodland without disrupting farming on the lower park fields. The Track is on a steep gradient and will have a 9ft Deer gate either end. 

This shot shows a bundle of lime tree saplings which we planted out over the Easter weekend. Brian Clapp helped me to plant 400 tree saplings, including 80 Acer, 40 saplings from each of the following varieties :  Silver Birch, Small Leaved Lime and Rowan, 15 Hazel, Blackthorn and Dogwood and 155 European Oak. All purchased from Perrie Hale Forest Nursery just outside Honiton. It was appropriate that Brian helped plant these trees as he helped to Plant Knappy Woodlands with his father approximately 43 years ago ! Now a semi mature Woodland.

Some of the items required, including spiral plastic rabbit guards !

Tree saplings planted showing canes, clear spiral rabbit guards and a portion of turf removed to allow for watering and the removal of competing weeds. We will weed kill approximately 1 meter radius around the sapling, this will allow the sapling to grow 3 times quicker.

A view showing more of the saplings planted out and spaced approximately 2.5 meters apart we have fenced the perimeter with a 9ft deer fence which was erected by Andrew Tuckers team from Luppitt.

Andrew Tuckers team erecting the 9ft high Deer gate at the new entrance to the copse. According to the www.carbonfootprint.com web site each tree will absorb 1 tonne of carbon dioxide during its lifetime, so our copse will certainly help to reduce the Woodhayes carbon footprint by 400 tonnes over 100 years !
