A pick of the lat­est and most in­ter­est­ing cladding prod­ucts for your self build, ex­ten­sion or re­model project

Trespa’s MeTeon

Trespa’s Meteon pan­els (shown on open­ing page) of­fer a highly con­tem­po­rary, low main­te­nance, durable op­tion for those look­ing for a cladding ma­te­rial with a dif­fer­ence. They are made from high pres­sure lam­i­nate (HPL) which con­sists of 70% wood fi­bre and 30% resins. Ac­cord­ing to Trespa, they have two key ben­e­fits over tim­ber cladding. The first is that they re­quire no rou­tine main­te­nance for the life of the prod­uct (BBA cer­ti­fied for 50+ years). Sec­ondly, they won’t fade. They have a global guar­an­tee for 10 years, but in the UK cli­mate, they can of­ten last many years more with min­i­mal change in colour. Ad­di­tion­ally, they are highly im­pact and scratch re­sis­tant. Although wood-ef­fect pan­els are pop­u­lar, the prod­uct isn’t re­stricted to wood looka­likes — there is a large choice of other colours and fin­ishes, in­clud­ing an eye-catch­ing metallics range. The in­stalled price for the Meteon pan­els vary de­pend­ing on the fram­ing sys­tem used. Prices range from £150/m2 to £250/m2. (The Meteon el­e­ment of this is ap­prox­i­mately a third, with the fram­ing sys­tem be­ing the largest el­e­ment.) The cost vari­a­tion largely de­pends on whether you want the fix­ings to be vis­i­ble or not.

Trespa’s pura sys­TeM

For those af­ter cladding boards, Trespa’s Pura plank­ing sys­tem (right) is well worth a look, too. The sys­tem has the same ben­e­fits as the Meteon, but comes as pre­formed planks. It is avail­able in both flush and over­lap­ping fin­ishes and can be in­stalled either ver­ti­cally (a pop­u­lar choice at present) or hor­i­zon­tally. It is fast to in­stall and Trespa sup­plies the whole sys­tem, in­clud­ing colour-co­or­di­nated trims. A typ­i­cal in­stalled price for the com­plete Pura sys­tem would be ap­prox­i­mately £130/m2, in­clud­ing ma­te­ri­als and labour. (trespa.com)

sioo:X

The pop­u­lar­ity of tim­ber cladding means prod­ucts which en­hance its beauty and pro­tect it from the el­e­ments are con­stantly be­ing devel­oped.

SiOO:X is an en­vi­ron­men­tally friendly, wa­ter­based wood pro­tec­tion sys­tem. The treat­ment prom­ises sig­nif­i­cant pro­tec­tion against un­even, patchy weath­er­ing and dis­coloura­tion, as well as against al­gae, fun­gus, spore and sur­face rot, not to men­tion splin­ter­ing and curl­ing. It is also largely main­te­nance free — it can be left for 10-15 years be­fore re-ap­pli­ca­tion should be needed. Boards can either be given a fac­tory fin­ish be­fore be­ing de­liv­ered, or can be treated on site.

Ap­plied in two stages, a wood pro­tec­tor is first ap­plied to pen­e­trate the fi­bres of the cell walls of the wood, where it forms a net­work of sil­ica crys­tals to cre­ate a bar­rier which is bonded to the sur­face. The sur­face pro­tec­tor is then ap­plied, bind­ing with the wood pro­tec­tor to pre­vent wa­ter pen­e­tra­tion. SiOO:X then cures by re­act­ing with at­mo­spheric car­bon diox­ide and mois­ture to form an in­sol­u­ble and flex­i­ble sil­ica net­work within the sur­face.

The min­eral sil­i­cate starts to turn tim­ber an even sil­ver/grey in 10-16 weeks. SiOO:X mid grey and light grey are specif­i­cally for use with sawn sur­faces and only avail­able as fac­tory-ap­plied coat­ings (top right and left). Avail­able from Russ­wood from £6 for 250ml. (russ­wood.co.uk)

porce­lanosa eX­Te­rior Bond­ing

Tiles have long been used as an ex­te­rior cladding ma­te­rial in many parts of the world — think the beau­ti­fully tiled façades seen all over Por­tu­gal, for ex­am­ple. How­ever, this is a rel­a­tively new sys­tem in the UK.

In ad­di­tion to in­ter­nal tiles, Porce­lanosa is now pro­duc­ing ex­ter­nal cladding sys­tems (above), in con­junc­tion with its high-tech di­vi­sion, Butech.

The sub­strate (for in­stance, the block­work) is first pre­pared be­fore be­ing clad with porce­lain tiles, us­ing me­chan­i­cal fas­ten­ings as an ex­tra form of re­in­force­ment along with suit­able ad­he­sives, be­fore be­ing grouted, with a min­i­mum 5mm joint.

Home­own­ers can choose be­tween a bonded façade or a ven­ti­lated façade — the lat­ter is the more ex­pen­sive of the two. Prices de­pend on the cho­sen tiles. (Porce­lanosa.com)

yukari shou sugi Ban TiM­Ber

Shou Sugi Ban (charred tim­ber cladding) is en­joy­ing huge pop­u­lar­ity among self-builders and ren­o­va­tors alike, of­fer­ing a rich and dra­matic ap­pear­ance, full of char­ac­ter. This an­cient Ja­panese tech­nique of char­ring tim­ber cladding means no two boards will be the same.

Other ben­e­fits in­clude nat­u­ral pro­tec­tion from UV rays and an ex­tremely tough and durable end re­sult. Charred tim­ber is also more re­sis­tant to fire and pests.

Yukari is a new type of Shou Sugi Ban — it’s 100% FSC (For­est Ste­ward­ship Coun­cil) cer­ti­fied and with new tex­tures to those pre­vi­ously seen. With a smooth, sanded sur­face, Yukari has a strik­ing con­tem­po­rary ap­pear­ance that works with both pe­riod prop­er­ties (as above) as well as be­ing suit­able for con­tem­po­rary new builds.

It is avail­able in stan­dard lengths of up to 4.9m through James Latham, and man­u­fac­tured by Shou Sugi Ban. The range, de­pend­ing on fin­ish, quan­tity and pro­file, costs ap­prox­i­mately £125/m2. (lath­am­tim­ber.co.uk)

co­rian® eX­Te­rior pan­els

While most of us are fa­mil­iar with the com­pos­ite ma­te­rial Co­rian® – made from a blend of min­er­als and acrylic poly­mer – as a work­top ma­te­rial, as an ex­te­rior cladding it is a rel­a­tive new­comer.

It comes sup­plied as large pan­els that can be built up seam­lessly to achieve any shape or form re­quired. The pan­els are fixed to pro­vide a ven­ti­lated façade that al­lows for thicker lev­els of in­su­la­tion to be in­stalled be­hind, and can also be used on ren­o­va­tions in or­der to im­prove on ex­ist­ing in­su­la­tion lev­els.

The ma­te­rial is durable, long last­ing and re­sis­tant to hu­mid­ity, fungi and bac­te­ria, plus the UV-stable colour runs through the en­tire thick­ness of the pan­els, which means the edges are the same colour as the face of the pan­els.

The pan­els use a me­chan­i­cal fix­ing sys­tem based on an alu­minium grid. They can be in­stalled by cladding con­trac­tors or pro­fes­sional cladding in­stall­ers. How­ever, in some cases as­sis­tance may be re­quired by an ap­proved Co­rian® fab­ri­ca­tor in work­ing the Co­rian® be­fore it is in­stalled (for ex­am­ple, if ther­mo­form­ing is re­quired).

On this ex­ten­sion to a 19th-cen­tury house in North Lon­don (above), de­signed by Al­i­son Brooks Ar­chi­tects, two ta­pered vol­umes have been added to project into the gar­den. The ends of each block are en­tirely glazed, while the sides are clad in Black­berry Ice Co­rian® pan­els. “Each trape­zoidal plane of the scheme is either fully glazed or fully solid — there are no punched win­dows,” ex­plains Al­i­son Brooks. “Both roof and wall planes are one ma­te­rial. This ap­proach cre­ates an ar­chi­tec­ture with­out mass and weight. It is more like the folded sur­faces of origami.”

Rain­wa­ter down­pipes are con­cealed be­hind the ven­ti­lated Co­rian® façade.

Co­rian® Solid Sur­face is dis­trib­uted in the UK & Ire­land ex­clu­sively by CD (UK) Ltd. The in­stalled cost is ap­prox­i­mately £600/m2. (cdukltd.co.uk)
