4. Fit the long fillet in the gap between the two roof
panels as shown in the photo.
5. Fix on the four corner strips with three 40mm nails in
each.
6. Measure the length of the roof panel and add 100mm
for cutting the lengths of felt. (Three lengths will be
needed). Once the felt is cut lay the pieces to overhang
the side of the roof by at least 60mm. Lay the third piece
of felt along the centre of the roof to overhang the other
two pieces.
7. Nail the felt around the outside of the roof every
100mm.
8. Place the Perspex panel into the window frame using a
suitable sealant, then nail the 20mm x 20mm interior
beading strips into place starting with the bottom strip.
For added protection we recommend using a clear
silicone seal around the edge of the Perspex.
9. Fit fascia pieces into place with two screws in each to
front and rear of shed.
Please read carefully
Your shed has been pressure preservative treated, which is designed to prevent rot and insect attack for
up to 15 years and to give softwood construction and landscaping timber products an extended and low
maintenance service life. The treatment is not intended to perform as a waterproofing agent.
When using pressure treated cladding timbers in the construction of sheds or garden buildings the
following guidelines should be followed to help prevent any water ingress:
1. The Timber Research and Development Association (TRADA) recommends a 16-19mm nominal
thickness for cladding timbers, this shed has a nominal cladding thickness of 19mm.
2. Fixings should only be driven marginally below the surface of the cladding timbers.
3. A suitable airflow should be allowed throughout the structure to assist on-going drying, during which it
is perfectly normal for some shrinkage of the cladding timbers to occur.
4. The dry, external timbers can have a water ingress protection added with the application of an
appropriate and well maintained water repellent coating. This would involve a proprietary water
repellent coating product which could be applied to the dry external timbers following the relevant
manufacturer’s guidelines. Recommended products include Thompson’s WaterSeal, Hickson Decor
Wax Coat and RESTOL Wood Oil.
5. For added protection and waterproofing we recommend using a clear silicone seal around the edge of
the Perspex & corners before fixing on the corner strips
